Executive summary

Lebanon is working towards medium term reconstruction, recovery and reforms program to align itself with the Millennium Development Goals (MDG). Recovery and reconstruction was one of the prime representations of the country at the Paris III conference in January 2007.

The Government elect (since November 2009) has adopted a policy note and an action plan in order to increase cost effective reliable availability of electricity in the country.

One of the major requirements for reliable supply is timely capacity addition to meet the growing demand; the flip side is that new investments can happen subject to operational efficiency and profitability of the entity responsible for supply of electricity in the country. The country has not witnessed increase in electricity tariff for more than a decade although the cost of import of fossil fuels (used for electricity generation) has increased by more than 300% which has severely impacted the operational margins of Electricitie Du Liban (EDL). Although international community has offered assistance to Lebanon in revival of its electricity sector, there has been an overarching requirement of considering environment performance of the system at par with reliable availability for consumption.

There are two possible approaches that can help curb the emissions as well as add to the energy security of the country:

- Addition of new generation capacities with better performance (low GHG emission) and /or induction of renewable energy facilities

- Reduction in consumption of energy in certain target sectors (Energy efficiency)

Building sector consumes a major portion of electricity in any country (around 40% in Lebanon) with modest recoveries and performance control over the equipments implemented and used in the building establishments unless specific performance standards are adopted at country level.

The United Nations Development Program (UNDP), through the funding from Global Environment Facility (GEF) executed the project for development of Thermal Standards for Buildings in Lebanon (TSBL) between 2002 -2005.

The major activities under this funding initiative were:


- Establishing climatic zones in the country- Carry out economic feasibility study of energy efficiency interventions in

the buildings along with energy analysis- Development of thermal standards for various kind of buildings- Development of technical guide and software tool for practicing

engineers and implementing agencies

Along with this, a major portion of the funding was used for capacity building, stakeholder consultation, technical workshops and conferences along with specific studies and development of regional coordination.

The thermal building standards developed as an outcome of this study could not get implemented in Lebanon for various reasons. In the year 2010, the construction sector licensing body, the Order of Engineers and Architects (OEA), through French Agency for Environment prepared a revised version of the thermal standards for buildings in Lebanon and approached Lebanese Standards Institution (LIBNOR), the statutory entity for standardization, for adoption in the country.

The adoption / implementation of thermal building standards require:

- Relevance of the standards for the growing building sector in Lebanon- Modalities of implementation of standards- Stock taking of concerns of stakeholders- Roadmap for short and medium term and integration with the existing

laws and legislations in the country.

The World Bank (WB) in conjunction with the Lebanese Centre for Energy Conservation (LCEC), and as part of a broader program support for energy efficiency in Lebanon decided to bridge the gap between the TSBL and its actual implementation through this assignment “Lebanon: Thermal Building Standards Review and Implementation Plan”, which may in-turn outline the fitment of the thermal standards and actual requirements / preparedness of the implementation structure in the country.

This assignment has following inter related objectives:

- Address fundamental requirements for an effective implementation of TSBL in Lebanon

- Review of the thermal standards developed in 2005 and 2010 and report their appropriateness for implementation and defining areas in which standards must be updated

11 | P a g e


- Help prepare Lebanese institutions and allied stakeholders for a successful implementation of a thermal building standards program by identifying barriers to implementation and developing the roadmap to address these issues.

During the course of development of assignment objectives, it was deliberated that implementation of TSBL in its present form may not be sufficient to meet the objectives of the National Energy Efficiency Action Plan (NEEAP) which details out various energy efficiency measures for the country with ambitious target of 1.4 mtoe over 20 years [NEEAP 2010].

It is therefore proposed to develop a prescriptive code for the country so that energy efficiency can be incorporated in the ongoing and near future construction. This prescriptive code can be used in short term and add minimum efficiency levels of equipment in the current thermal standard. In the medium term the performance based Building Energy Efficiency Code (BEEC) can be developed and implemented. Simultaneously efforts can be made to transform the market to take over from the present condition to matured international best practices.

This study has thus been expanded from comparison of the two TSBL (2005 and 2010) to proposing a roadmap for the country to graduate to a comprehensive building code.

The roadmap for BEEC in Lebanon has been proposed considering the fast pace implementation / construction of new buildings in the country vis-à-vis the availability of resources, tools and techniques and preparedness of the country to switchover from the status of limited regulation in terms of building Energy Efficiency (EE) to a performance based BEEC.

The possible energy savings through efficient building envelope range between 10 – 50% depending upon the building size, climate, internal load and allied parameters. Usually in large buildings, the energy saving potential through building envelope is only upto 20% whereas additional energy saving potential of similar magnitude can be obtained through use of efficient lighting, Heating Ventilation and Air Conditioning (HVAC) and Solar Water Heating (SWH) systems. Hence, the scope of elemental BEEC is proposed to include requirement of efficient lighting, HVAC and SWH systems along with building envelope.

Short Term Road Map

For an initial period of two years, the short-term roadmap has been proposed with a target of implementing an elemental BEEC to capture immediate opportunities of improving energy efficiency in building sector. For this

12 | P a g e


purpose, the approach for modifying the existing TSBL (2005 and 2010) for inclusion of prescriptive requirements for energy efficiency lighting, HVAC and solar water heating system have been presented in this report. To begin with, elemental BEEC may be adopted for public / Government buildings and later may be mandated for all the buildings.

Medium Term Road Map

It is proposed that after first two years, staged replacement of theprescriptive elemental code by a performance based BEEC takes place. Similar to thestaged implementation of the elemental BEEC, the performance basedBEEC should also be implemented in multiple stages i.e. first forgovernment buildings and then for all buildings. Needless to mentionhere that until the performance based code becomes mandatory for anyparticular type of buildings, they would need to comply with theelemental code. Thus, life of the elemental code extends beyond twoyears and continues till the time performance based BEEC becomesmandatory for all building types.

Considering the overlap of activities for the two versions of BEEC andimportance of both, the elemental BEEC and performance base BEEC; a medium termroadmap for implementation of performance based building energyefficiency code has also been proposed and presented separately inthis report. The time-frame for implementation of medium term roadmaphas been proposed as three years starting from the end of second year.In medium term roadmap, it is intended that the country would worktowards establishment of testing facilities, policies for performancemonitoring and inspection (post implementation of buildings) throughtrained officials and can look forward to meeting the global bestpractices of BEEC.

The details of the short & medium term plan can be summarized as follows:

Short Term Medium Term

Duration 2 years 5 years

Target Mandating Elemental BEEC Mandating BEEC

Purpose Quick response to market Stabilizing as per international best practices

Feature Prescriptive approach through use of Performance based

standardized equipments (Standards & labelling program of LIBNOR)

approach with actual quantification of efficiency improvement – whole building performance evaluation

The implementation of BEEC would also result in direct reduction of primary and secondary energy consumption. The present Kyoto regime permits development of such initiatives as candidate Clean Development Mechanism (CDM) opportunities which can help overcome the investment barriers and reduce payback period by providing direct returns to the investors through transaction of Green House Gas (GHG) emission reductions. The possibility of development of CDM projects for building efficiency gains projects is also covered in this report.

1. RATIONALE AND SCOPE OF ROADMAP FOR BEEC1.1 RationaleLebanon was involved in a long civil war until 1990 followed by regional and national instability that has resulted in a rather neglected growth of energy sector. The country is majorly dependent on service sector activities with energy intensity of 0.20 toe / $ 1000 which is about 33% more than the global average. [Isabella 2011]

Lebanon is highly dependent on service sector, recovering from war and is banking on the reconstruction of infrastructure along with a spur in new construction activities. In addition to this, the country is dependent on fossil fuel for more than 95% of its electricity demand with inefficient generation facilities that can meet around 60% of the demand of its 4.2 million people [Isabella 2011].

It is therefore imperative that energy conservation and efficiency gain activities are carried out to arrest wastage and reduce dependence of the country on import of energy (electricity) and fossil fuel. Recently, the Government of Lebanon has taken up an ambitious plan of increasing its Renewable Energy share to 10% by 2013 [Isabella 2011]. In addition to this, additional capacity of about 600 MW is proposed for implementation.

The proposed new capacity addition, both in the form of renewable energy as well as conventional generation will take its own course of implementation; whereas careful attention to the Demand Side Management (DSM) can also add to the efforts in increasing electricity availability within Lebanon. DSM in building sector would require addressing the four phases shown in Figure 1.1

Figure 1.1: Phases of Demand Side Management (DSM) in building sector

A very careful planning is required to ensure that limited resources are devoted to the highest-priority, highest-impact actions in the near term while laying the groundwork for longer-term improvements. The planning is therefore required to take the investment of time and resources consumed in development of TSBL (2005 and 2010) to a logical conclusion through development and implementation of building code.

It is of utmost importance that the planning is in tandem with the pace of construction and developmental activities that the country is witnessing. A

PLANNING IMPLEMENTATION MONITORING REVIEWING


detailed performance based building code might take considerable time in development, implementation and acceptance by market players. A rather smart approach should be to look at the available resources, time and goal at the same time and execute the plan accordingly.

It is always easier to adopt deemed savings by use of equipments with benchmarked performance than to measure actual performance due to limited availability of technical expertise as well as equipment for measurement. With availability of standards (with LIBNOR) for performance of various building equipments such as solar water heaters, compact fluorescent lamps, air conditioning units, refrigerators, electrical and gas water heaters; it is easier to develop a philosophy for building performance evaluation through equipment benchmark standards.

Once the short-term goals are achieved with prescribed measures, and the systems are established to evaluate and revisit the achievements, a rather thorough approach for performance based building code can be implemented to device the techniques for better penetration and enhanced results.

The globally practiced approach, with slight modifications to suit the requirements of Lebanon, is therefore proposed to form the basis for development of a holistic BEEC with initial emphasis on quick turnaround through prescriptive code followed by performance standards for buildings.

With respect to Lebanon:

- 2003 onwards development of TSBL is taking place, it is time to move from just the building envelope to BEEC.

- Refurbishment as well new construction activities are happening all over the country, marking a change in the building sector and its participation in the growth of the country.

Lebanon has well established setup of statutory entities such as LIBNOR with operational insight on issues pertaining to performance standardization, which can be leveraged during the course of development of performance standards for buildings with reasonable assurance and controls.

1.2 GoalLebanon passed Law 462 in September 2002 to regulate the power sector. The primary objective of the law was to establish independent statutory bodies / regulatory commissions to detail out strategy for energy conservation as well as increased share of renewable energy in country. The law was reviewed and amended in November 2006 with a new law 775 to permit Independent Power Production (IPP) for personal use. The revised law 775 has not addressed the

16 | P a g e


issue pertaining to legal framework for private sector players in electricity generation which is responsible for meeting more than 33% of electricity demand through backup operations. It is important to note that none of the two laws were actually implemented.

Lebanon has not added new electricity generation facilities in past 15 years although a steady increase in demand ranging between 3 to 8% has been recorded. The resent estimates of the line ministry (MEW) indicate a shortage of 700 MW in country. To further aggravate the situation, the building sector is witnessing a spur in reconstruction activities as well as new constructions resulting in increased demand of electricity, which is essentially been supplied at a subsidized rate in the country.

Lebanon being a part of League of Arab States (LAS) may consider aligning itself with larger interests of the region. The European Commission along with LAS has developed the framework of Arab EE Directive with participating countries to set EE targets and assign public entities to draw a three year NEEAP [NEEAP 2010]. Under this framework, the overall national indicative target for building sector has been kept at 5% reduction in growth rate beyond the existing average baseline consumption of 5700 GWh.

The proposed target requires serious measures towards setting up standards for the existing and new buildings, to identify acceptable performance levels for building envelope as well as for equipments used within the structural framework of buildings.

This assignment is therefore to review the existing thermal building standards for Lebanon and finalize a roadmap for their adoption as an integral part of building approval procedures in the country.

1.3 ScopeThe original scope of the assignment was:

Reviewing existing thermal standards developed in 2005 and 2010 and either ratifying these standards or defining areas in which standards must be updated;

Identifying and outlining any factors related to establishing thermal standards for new buildings, including categorization of standards and application for different types of buildings (residential, commercial, etc), and legal and regulatory structure to promote adoption of TSBL that has not been considered in past studies.

Reviewing existing thermal standards, as appropriate, in light of changed fuel and electricity production costs, and changes in building design and construction practices and energy utilization;

17 | P a g e


Developing roadmap for the implementation of a Thermal Standards Program for new buildings in Lebanon, including consideration of legal and regulatory requirements for mandatory adoption of thermal building standards;

During course of review of the existing thermal building standards (2005 and 2010) and comparison with international best practices, it was deliberated that targeting building envelope may not bring in intended efficiency gains and thus instead of developing a roadmap for induction of TSBL in the building approval process, a roadmap for prescriptive BEEC followed by performance approach should be looked as the revised scope.

2. CURRENT STATUS OF ENERGY/THERMAL STANDARDS IN LEBANON

2.1 Lebanon Energy ScenarioLebanon is dependent on import of fossil fuel for generation of electricity; almost 95% of the electricity generated in the country is either supplied by EDL or through local backup production. Although the country is nearly 100% electrified, the country sustains 40% of the day through various backup arrangements.

In addition to the in-house production, the country relies on imports from within Middle East & North Africa (MENA) region, with major imports from Syria, Egypt and a small portion from Jordan. The contracts with Egypt and Jordon are essentially for surplus electricity which is supplied to Lebanon during off-peak hours. Since August 2010, Lebanon is facing problem with imports from Egypt, whereas early this year Jordon suspended supply to Lebanon due to disruption of regional gas pipeline.

To further aggravate the situation, it has been observed that the operation efficiencies as well as plant availability of two of the generating facilities have gone down to 60% and 54% respectively .

In addition to the significant gap between generation and demand, the electricity sector is also observing high transmission and distribution losses, approximately to the tune of 15% and non t3echnical losses of about 17.8% [El-Fadel 2009].

19 | P a g e


The total installed capacity in the country is 2312 MW (as per 2009 data). The electricity demand in the country is approximately 15000 GWh against which EDL was able to supply 11522 GWh. The balance has been partially met through backup generation [Isabella 2011]. The electricity tariff in the country has not changed for more than a decade; the last tariff fixation was carried out on the 1996 oil price (import at $ 25 / Barrel) with delivery tariff of $ 0.094/kWh against the average landed cost of $0.17/kWh to EDL. EDL is thus operating through subsidies.

The focus should therefore be on:

- New capacity addition through conventional as well as renewable energy sources

- Tapping of energy efficiency opportunities within operational setups / sectors with residential consumers consuming the subsidy

- Better regional coordination for a phase change from present electricity imports to electricity exchange among the participating countries in the region. Aligning the country with developments taking place in the region and actively participating in the opportunities of international cooperation to develop long term strategy for sustainable development including opportunities to develop candidate CDM project for possible additional revenue stream through transaction of emission reduction.

The Ministry of Energy & Water (MEW) has developed a policy paper in June 2010 with 10 strategic initiatives to augment power sector indicating a 3 – 4 years time frame for the turnaround.

2.2 Institutional FrameworkLebanon has following entities responsible for institutional framework for energy sector:

2.3 Regulatory FrameworkThe regulatory framework for implementation of policy directive for voluntary as well as compliance for built space is present in Lebanon with various statutory bodies both under the government / line ministries as well as

independent entities like the OEA with appropriate powers to deliver the intended output from this sector.

It is envisaged that for induction of BEEC, strengthening of regulatory framework is required in order to:

- Integrate BEEC in the licensing / approval framework for buildings

- Understand and apply the BEEC in correct manner for both retrofit as well as new constructions

- Monitor actual performance and impose penalties for non-compliance

In addition to this, the regulatory framework may also consider role of third party independent agencies to validate and certify the performance of buildings as well as the equipment used in it. Globally, it is observed, that public private partnership (PPP) approach has worked successfully in achieving desired results.

2.4 Major Efforts and AchievementsThe development of thermal building standards in Lebanon has been one of the major works carried out targeting building sector to achieve intended results of energy conservation. Through this important initiative, some of the key tasks completed with respect to buildings in Lebanon were

- The study of climatic zones was carried out and completed- The building envelope performance indicators for specific climatic

zones were established through simulations- Energy analysis and feasibility of sample buildings- Technical guide and software tools developed with a proposal for

voluntary implementation for 5 years followed by mandatory compliance.

- About 2000 professionals were reached out to share the results of this initiative

- Incentives proposed for adopting TSBL in the new building law.- Establishment of LCEC

Since its establishment LCEC has institutionalized national efforts to:

- Improve and raise awareness of energy efficiency in the main sectors of the economy

- Encourage the use of renewable energy technologies through technical and policy support

- Provide reliable data on energy demand patterns and distribution

Further, in its agenda, LCEC intends to check the growth of energy demand in various sectors with measurable and sustainable global benefits in terms of long-term GHG emissions reductions, which will contribute to the mitigation activities within the country.

LCEC is investigating the possibilities of GHG reduction by:

22 | P a g e


- Providing businesses and the public sector with expert advice, finance and accreditation

- Stimulating demand for energy efficiency and renewable energy products through developing national awareness campaign

- Developing energy efficiency standards and labels- Creation and support of Energy Services Companies (ESCOs)- Establishing partnerships with public and private sectors- Representing Lebanon in international energy efficiency and

renewable energy associations- Providing a national energy database- Promoting the CDM for carbon offsets

Lebanon has also fixed up targets under the NEEAP. These targets have been fixed in line with the European Commission Directive (2006/32/EC). The first NEEAP for 3 years has commenced from 2011 and will continue until 2013. The planned measures cover following areas:

1. Ban on import of incandescent lamps in Lebanon by year 2012. The initiative will result in saving of 1401 GWh.

2. Adoption of Energy Conservation Law and institutionalization of LCEC.

3. Promotion of decentralized power generation through RE sources like Solar PV and Wind for residential consumption. A capacity addition between 50 – 100 MW is planned to be carried out by 2015.

4. Implementation of Solar Water Heaters in residential sector with a possible savings of more than 300 GWh / year.

5. Implementation of efficient public lighting system with a possible savings of about 6 GWh/year.

6. Implementation of 60 to 100 MW of Solar energy and 100 to 200 MW of wind in next 5 years.

7. Hydro capacity addition to the tune of 100 MW by 2015.

8. Development of projects around other non-conventional technologies including but not limited to Geothermal and Waste to Energy.

9. Establishing Building Energy Code to save about 16000 GWh in next 20 years

3. FEATURES OF EFFECTIVE BUILDING ENERGY EFFICIENCY CODE(S)

3.1 Building Energy Efficiency CodeThe BEECs were introduced in most of the developed countries for residential and non-residential buildings since the first oil crisis in the mid 1970s. These codes are mandatory in several countries. In some countries, the energy efficiency codes have been integrated in the building codes and in some other countries, these codes are standalone. In most countries, these codes have been formulated at the national level and enforced at the local level. The following sections have been essentially drawn from the World Bank report – ‘Mainstreaming Building Energy Efficiency Codes in developing Countries’. [WB 2010].

3.1.1 Scope

The BEECs primarily address new construction but some of the codes are also applicable to extension and alterations in existing buildings with some renovation. The BEECs principally cover two aspects:

1. Thermal performance of the building envelope 2. Energy efficiency of equipment and devices installed during building construction

The energy efficiency of the equipment and devices can be determined either by BEECs or by separate energy efficiency standards for appliances

3.1.2 Compliance Approach

Based on the compliance approach, the BEECs are often categorized as prescriptive or performance based.

Prescriptive approachThe prescriptive approach is generally component specific and give the

minimum performance levels for various components. In case of envelope components such as roof, wall, window, the maximum U factor is provided. For HVAC systems, service water heaters and lighting systems, requirements are given for sizing and minimum energy efficiency values.

For developing countries, especially, those which are introducing energy efficiency codes, following benefits can be achieved by adopting simple, prescriptive and component performance based BEECs:

25 | P a g e


o Gradual market transformation with stronger supply chains capable of meeting energy efficiency requirement

o Building up of compliance enforcement capacity

Table 3.1: Benefits of prescriptive approach to different stakeholders

Stakeholders BenefitsDesigners and builders compliance simpler to understand and

executeProduct manufacturers a firm baseline for their product development

or retooling their product linesEnforcement system checking and inspecting prescriptive

requirements to help put in place fundamentals of the compliance process

All and others Better understanding of energy efficiency features expected in a building

Performance based approach

According to [WB 2010], generally the performance based approach refers to specifying the annual level of overall energy consumption (energy budget) in the targeted building and the methodology to calculate the sub Energy budgets of different energy uses regulated by the BEEC, such as space conditioning, lighting, and service water heating.

Performance based compliance approach provide more flexibility in building design and equipment selection as compared to prescriptive based approach. However, this requires more skills and sophistication for code compliance.

3.1.3 Adoption Approach

Based on the preparedness of a country, BEECs can be adopted as mandatory or voluntary.

Mandatory BEECs

If a country has some existing structure of codes like building structural/fire codes, mechanical codes, and electrical codes and also has the

26 | P a g e

In both the approaches, many BEECs have certain mandatory measures.


infrastructure to implement those codes, the BEEC can be adopted as mandatory. The mandatory codes yield better compliance rates leading to more energy savings.

Voluntary BEECs

The BEECs can be adopted as voluntary till there is sufficient preparedness in terms of involvement of stakeholders. Voluntary BEECs generally have low compliance.

3.2 International Best PracticesFourteen international best practices, as compiled from various sources, are listed in the Table 3.2. The best practices are categorized into three aspects:

Technical scope of codes Mechanism for implementation and enforcement of codes Code implementation support

Table 3.2: International Best Practices

3.2.1 Technical Scope of Codes

1. Whole building scope

One of the very prominent and clear best practice that has emerged after studying various reports is that the codes that include building systems in their scope in addition to the envelope, achieve a higher level of overall energy efficiency than those that only address single systems such as building envelope alone. It has been identified that doing so not only captures most of the energy savings opportunities, but also proves to be cost effective. A code that sets strict efficiency requirements for HVAC systems in the absence of reducing energy leaked through the envelope

will not be cost-effective, overall, to the owner. The same is true if the code sets stringent requirements for the envelope without specifying HVAC efficiency requirements.

As per the report “Can building codes deliver energy efficiency? Defining a best practice approach” [RICS 2008], the code should be performance-based and should take the form of an integrated energy calculation that includes the demands generated by the building fabric and its occupants upon all the fixed building services, and the performance of the systems that satisfy those demands. It should include all energy supplies to the building. The wide scope and flexibility of this structure allows changing energy policy priorities to be reflected without changing the basic structure: for example by changing the relative weights applied to different energy supply sources.

Further, [RICS 2008] makes no recommendation about the common metric into which each consumption is converted as this will depend on the energy policy priorities of the implementing government or authority. At the moment climate change is a key policy driver in many countries, but this has not always been so and may not always be so. Other possibilities include primary energy, or might prioritize electricity or imported fuel consumption.

According to the report prepared by the Building Codes Assistance Project of the Alliance to Save Energy – ‘Building Energy Codes Best Practices Report for APEC Economies’ [ASE 2009], among the APEC countries Australia, Canada, Hong Kong, Japan, Korea, New Zealand, Singapore, and the United States all set energy codes which cover most systems. Typically, codes cover the envelope, lighting, HVAC, service water heating, and electrical power.

2. Addressing climatic variation

According to [ASE 2009] the code should recognize different climates and need for differences in efficiency requirements. The World Bank working paper [WB 2010] emphasizes that greater attention should be given to development and implementation of appropriate BEECs in warm-climate developing countries. There is a large gap in the adoption of BEECs between cold-climate and warm-climate developing countries. Same aspect of climate is also highlighted in [IEA 2008].

The United States addresses 8 climate zones in the residential and commercial energy codes. Climatic differences are contained together within the prescriptive requirements, and updated together.

28 | P a g e


3. Addressing residential and commercial buildings

Codes that do not address all major building systems lose opportunities to save energy, but so do codes that cover only part of the building sector. As per [ASE 2009] and [IEA 2008], code requirements typically have differences between low-rise commercial, multi-family housing, public and private, and the type of commercial use, so it is important to assess the construction market in order to target energy conservation efforts where they can have the greatest impact.

According to [ASE 2009] the following APEC economies all have building energy codes for construction in both their commercial and residential sectors: Australia, Canada, China, Hong Kong, Japan, Korea, Malaysia, New Zealand, Philippines, Russia, Singapore, Chinese Taipei, and the United States.

4. Specific calculation structure

On the basis of various studies related to building energy efficiency codes, following three practices are identified with respect to specific calculation structure:

1. Integrated energy metric should be compared with that of a reference building

2. There should be a single calculation procedure for integrated energy metric for ease of compliance

3. Generic targets in kWh/ m2/yr are good for existing buildings and should be based on measures data

The study [RICS 2008] states that as best practice, the calculated integrated energy metric should be compared to that of a reference building of the same size and geometry but with defined elemental properties, such as thermal resistance of envelope elements, boiler efficiencies. These elemental properties should be clearly defined and should allow the reference building energy metric value to be calculated without further input.

With this convention (and without the use of general ‘improvement factors’) a designer and regulator knows that satisfying all the elemental requirements will automatically meet the calculated target. Therefore, in

29 | P a g e


practical terms, the regulation appears to be identical to one based on elemental values, but retains the flexibility of an integrated calculation.

The study further shows that a single procedure ensures consistency of calculation and removes the risk of market competition for ease of compliance between rival procedures. Alternative calculation procedures may be allowed but should be subject to extensive checking for consistency with the preferred method. The compliance target for integrated procedures can be set either using a general consumption intensity, typically kWh/ m2/yr, for different types of building or with a customised target that reflects the calculated consumption of a reference building of identical size, shape and use to the actual building. Simpler methods assign points to different features rather than applying an explicit calculation.

The two approaches are not mutually exclusive. Regulations may have prescriptive requirements for some features – for example air-tightness – and performance limits on others – such as summer overheating. Elemental methods often include trade-off rules, for example to allow lower insulation levels in some elements to be offset by higher ones elsewhere. Integrated methods commonly include limits on the performance of individual elements.

Further, [RICS 2008] states that generic targets are typically expressed in kWh/ m2/yr with different target values for different building types, such as offices, schools, and sport halls. Ideally such targets should be based on measured performance of a representative sample of buildings, though this is obviously impractical for new buildings. They are conceptually straightforward, but in practice it is difficult to derive targets that are reasonably equitable between different buildings of apparently similar types. For example, ‘hotels’ might be a single classification, but different hotels provide different facilities and serve different markets. Put another way, a generic target will result in different elemental requirements for buildings that do not precisely match the standard building configuration.

A single target value is probably unrealistic, and even multiple classes of, for instance, hotels will not completely deal with the issue. Customized targets are based on a reference building that allows the energy target to reflect the particular mixture of activities within the building. The reference building has the same size and geometry as the actual building but each element has a standard level of performance. Thus, in the reference building, U-values of envelope elements are fixed – as are the efficiencies of boilers. In this way, a building containing a specific mixture of activities is compared with one with identical use. The impact of some types of data error, such as physical dimensions, is alleviated because the same error is applied to both the actual and reference

30 | P a g e


buildings. This is particularly useful when the method is applied to existing buildings, for which data quality is likely to be relatively poor. With careful design of the process, it is possible to combine the advantages of both approaches.

The elemental performance levels set for the reference building of an integrated method comprise a set of requirements that guarantee compliance. Therefore, there is no need to carry out the calculation for a building that complies with all the elemental requirements. Only if the designer chooses to take advantage of the flexibility offered by the integrated approach is a calculation needed.

5. Calculation procedure

As per [RICS 2008], there should be a single recommended calculation procedure which should be inherently flexible but should have a user interface designed for regulatory purposes, rather than general design purposes. A single procedure ensures consistency of calculation and removes the risk of market competition for ease of compliance between rival procedures.

General design interfaces are unnecessarily complicated for regulatory purposes. Specifically-designed interfaces should be easier to check and are likely to be less prone to user error.

3.2.2 Mechanism for implementation and enforcement of codes

1. Regular updating of BEEC

Some governments only periodically update their building energy codes while others have a process in place for regular improvements. An automatic update ensures the code will continue to evolve and reflect changes, requirements, clarifications and new opportunities to increase energy efficiency.

According to [ASE 2009], as energy codes become outdated, drifting away from common practice and even farther from innovative building solutions, they quickly lose their effectiveness. It is important that codes reflect cost-effective energy-saving practices and products and keep up with market developments. If not, builders and contractors who pursue least-cost construction options will continue to prevent a portion of the building market from improving.

31 | P a g e


According to [WB 2010], the BEEC development and revision cycle as shown in Figure 3.1 is complex, quite lengthy, and costly. In some developing countries, it has been supported through funding from bilateral and multilateral development agencies.

Figure 3.3: BEEC development and revision cycle [WB 2010]

2. Staged implementation

As per [RICS 2008], Building Energy Codes that do not include an integrated calculation procedure should be designed to be steps towards such a structure. The recommended integrated calculation structure is only practicable given an adequate level of understanding and training amongst designers, builders, and those who must enforce the code. This will not always be present, and elemental codes – perhaps including provision for some trade-offs may be as far as it is reasonable to go.

It is desirable to move to an integrated calculation when circumstances allow and this possibility should be borne in mind when introducing elemental codes.

The documents further suggest a typical development sequence of building energy regulations:

2. Survey local buildings,

3. Technical, energy economic analysis

protocol

6. Technical and capacity building public awareness

7. Evaluation of energy savings and

effectiveness of BEEC


a) Elemental thermal requirements

b) Add trade-offs between elements

c) Fully integrated calculations

d) Extension to energy performance rating

From the review of various codes covered under international best practice study, it has been observed that several revisions of energy codes have been carried out in order of increasing sophistication. In any particular country, this typically represents a historical sequence that reflects changes energy policy concerns: for example developing from concerns about the availability and price of oil and gas; towards global environmental concerns. The increasing complexity is only feasible with a parallel increase in the level of understanding amongst designers and builders, and a well-developed and increasingly costly infrastructure to educate and police the regulations.

In practice the position of an individual country in the sequence seems to be primarily determined by this level of supporting infrastructure more than by differences in policy drivers. Most countries have taken several decades to move through this sequence and many regions of the world are still in the early stages of code development.

3. Mandatory compliance

As per [ASE 2009], a voluntary code is much like a voluntary program, without financial incentives, recognition, or any of the other typical elements found in these programs. The intent of codes to set a minimum baseline for new construction also implies that the level of efficiency is such that it is in the best interest of all citizens.

[IEA 2008] also highlights importance of mandatory compliance of BEEC. It states that “Because the efficiency of a new building will influence its energy consumption until renovation or even the whole lifetime, the decisions taken during design and construction will influence decades of building use. Lost opportunities in the construction phase will lead to increased costs if done at a later stage and can wildly inflate the running costs for future users. While individuals continue to determine much about a building’s fate, the energy efficiency of a new building should not be viewed only as a matter for individual choice but as a more collective issue, influencing society at large and a future generation of building users”.

33 | P a g e


According to [RICS 2008], as a general principle, mandatory minimum performance levels should reflect an assessment of the balance of costs and benefits to society, including external costs. Typically, codes reflect common practice, as well as materials and equipment that are readily available. The justification for mandatory codes is that there should be a societal benefit that would not be gained in the absence of legislation.

The fundamental justification for minimum standards is to require people or organizations to take steps that they might not take voluntarily. This lack of action may be due to ignorance, or because the benefits do not accrue to those who have to take and pay for the actions. Typically, this is because the benefits are societal rather than individual.

From an economic perspective, the compliance levels should reflect best estimates of whole-life costs and benefits to society as a whole. Buildings have long lives and so the costs and environmental impacts inevitably depend on uncertain estimates of the future. These may be unrecognized or incompletely recognized by the market place – and hence form a justification for regulation.

4. Thorough enforcement procedure

In general, code compliance is viewed as a serious problem. There are many strategies for enforcement along with some essential elements. As per [ASE 2009], a review of the design plans to check for code compliance catches problems before construction and can facilitate low cost fixes. Additional site inspections during construction are essential for checking on the quality of installation and the accuracy of following through on design details important to efficiency and the code requirements. In addition to inspectors who know how to inspect for efficiency, the building sector must also know how to demonstrate compliance. Clearly defined policies/tools for demonstrating code compliance are essential. Importance of thorough enforcement procedure has also been identified in [IEA 2008], [WB 2010] and [REEEP 2010].

5. Penalties for lack of compliance

Several APEC economies impose penalties for noncompliance with building energy codes. Penalties for not complying with the energy code can include stopping construction, withholding permits, levying fines and even imprisonment [ASE 2009], [IEA 2008]. According to [ASE 2009], the Building Construction Authority in Singapore operates under the Ministry of

34 | P a g e


National Development and is accountable for building regulation enforcement. Non-compliance with the Building Control Act and subsequent regulations results in a significant penalty– an individual is found to be guilty of an offense and can be fined or imprisoned for up to six months. Continuing failure to comply may result in additional fines.

6. Track compliance rates

Unless code compliance is measured, it is difficult to make improvements, understand where gaps exist in education, and account for related energy savings. According to [ASE 2009], in China, as in many large countries, local governments have the responsibility for adopting national codes. City governments are in charge of enforcing the requirement for designs reviews and site inspections. Since 2005, these must be carried out by a certified independent organization. If this process is not complied with, construction will be prevented or suspended, if already started. If the building is complete and not in compliance, it will not be allowed to be sold or used.

Under Japan’s Energy Conservation Law - 2005, a mandatory report is required to be submitted on energy conservation to local authorities on all new construction, additions, alterations, major repairs, and remodeling for homes and buildings over 2,000 square meters. Penalties are incurred if the project is not compliant; however, the process does not involve site inspections. The submission rate is reported to be 100% by the Ministry of Land, Infrastructure, and Transport and compliance is reported to have gone up between 2000 and 2005. Further, [ASE 2009] mentions that in Korea, building owners must submit an energy-saving worksheet signed by a licensed professional, such as architects and mechanical and electrical engineers, for approval. This office has the option to audit the buildings after construction and revoke the permit or order the building to be rebuilt if elements of the energy-saving worksheet have not been implemented.

3.2.3 Code implementation support

1. Code training and certification

As per [ASE 2009], there are no examples found to demonstrate required training or certification on the energy code for building officials or builders and design professionals. However, there does appear to be training available in many countries. Training may be helpful at several levels involved in the implementation of code including but not limited to building designers, architects, professionals for building services such as lighting, HVAC. In addition, separate training programs for officials involved with evaluation and permission related processes is required for better implementation.

The report further says that in some countries, induction of the code and related skills in the academic curriculum has helped a great deal in developing trained manpower.

2. Voluntary high performance incentive programs

As per [ASE 2009], countries that have building energy codes but are interested in achieving additional cost-effective energy savings can adopt advanced code amendments or voluntary high performance incentive programs. Another powerful strategy for reducing energy use in buildings is combining energy codes with voluntary programs such as ENERGY STAR, Home Energy Rating System (HERS), or Leadership in Energy and Environmental Design (LEED) systems. The code establishes a bare

minimum for energy efficiency while the program encourages innovation and provides incentives for better performance.

Figure 3.4: Role of voluntary and mandatory programs for energy efficiency [Concept - ASE 2009]

36 | P a g e


3. Demonstration projects

As per [RICS 2008], and [REEEP 2010], programmes should demonstrate the feasibility of buildings that exceed current regulatory minimum performance levels. This is required to build industry confidence by ensuring that the technical feasibility and cost of higher level of performance have been properly and practically explored before making them mandatory.

Although integrated calculation methods can alleviate the costs of substantial changes in requirements, it is preferable to demonstrate feasibility and provide time to allow the construction industry to become familiar with new demands before they become mandatory. This will reduce the risks associated with new techniques.

3.3 BEEC Development and Enforcement

3.3.1 Code Development

Code development is the process of updating energy codes to match advances in building science and construction practices. Developing a BEEC is an elaborate process requiring a variety of data and analyses. It is critical that building energy code provisions are consistent and conflicts between codes are minimal. Four issues need to be considered for the development of a BEEC [WB 2010]:

1. Decide whether the code should emphasize simplicity (and thus easier application) or provide for flexibility to allow designers and architects to find effective ways to meet the code requirements. In new code developments that cover all new buildings, often both prescriptive and performance based compliance paths are introduced, allowing designers to choose. Especially for smaller, less complex buildings, the simpler prescriptive path is generally preferred.

2. The code needs to be technically accurate. The prescriptive and performance compliance options should be roughly equivalent, so that one does not become a loop hole. Also, for energy calculations to more closely reflect reality, code requirements should take into account design flaws, such as thermal bridges due to metal framing around windows, metal studs in walls, and projecting concrete balconies.

37 | P a g e


3. The code needs to take into account the local availability and costs of equipment and materials.

4. The code requirements should be beneficial for society as a whole. This means that any additional costs of implementing the necessary measures, plus the costs of any supporting programs are balanced by energy savings and other benefits over the lifetime of the building, if not less.

3.3.1 Code Enforcement

Enforcement is the process that building inspection departments undertake to ensure that site plans and construction follow the previsions of the energy code. Without a significant emphasis on enforcement, compliance diminishes, and the outcome is always the same: new building or renovation projects that fail to realize their full potential for energy savings and the myriad benefits that go along with them.

Enforcement Options:

Even though most countries do not integrate the BEEC into the general building code, according to [WB 2010], most experts agree that the enforcement of BEECs should be integrated into the regular enforcement system for the general building code with plan review and inspections as part of the routine construction process. This will, however, be effective only if there is a sufficient number of well trained code enforcement staff in addition to compliance manuals, forms, and software. Separate enforcement would require the build-up of a separate enforcement infrastructure that would be even costlier and could easily double the number of inspections that need to be done before a building is allowed occupancy.

Table-3.3 presents various key features, requirements and implications related to enforcement of BEEC through three institutional options.

Table 3-3: Institutional options for enforcing building codes (Source: [WB 2010] Adapted from BRE (2008), p. 29 (based on Maine Public Utilities Commission (2004))

Examples United States; prevailing option

According to [WB 2010] almost universally, the main reasons cited for lack of enforcement are high enforcement costs and under resourcing of public agencies, including for staffing and staff training, inspectors’ lack of qualifications and specialist knowledge, and finally, the perception that the energy saving building regulations are not as important as safety related regulations.

The solutions proposed for better enforcement of BEECs are quite similar in different regions of the world, including the following:

39 | P a g e


Impose political energy savings or CO2 reduction targets on all levels of government to heighten the importance of energy efficiency matters.

Provide sufficient resources for enforcement by government agencies, with budgets supplemented by utilities, carbon finance, and other interested parties.

Make specialist training available for code officials and all trades involved in building issues, with budgets supplemented by utilities, carbon finance, and other interested parties.

Establish a system of accredited third party enforcement, possibly in conjunction with government spot checking and significant sanctions against fraudulent approval.

Provide information and incentives to builders and homeowners. Consider penalties for non compliance in the longer term.

3.4 Energy Efficiency GovernanceAs per [IEA 2010] Energy efficiency governance is the combination of legislative frameworks and funding mechanisms, institutional arrangements, and co-ordination mechanisms, which work together to support the implementation of energy efficiency strategies, policies and programmes.

The International Energy Agency (IEA) conducted a global review of many elements of EE governance, including legal frameworks, institutional frameworks, funding mechanisms, co-ordination mechanisms and accountability arrangements, such as evaluation and oversight. The research tools included a survey of over 500 EE experts in 110 countries, follow-up interviews of over 120 experts in 27 countries and extensive desk study and literature searches on good EE governance. This study has identified three main aspects of energy efficiency governance: enabling frameworks, institutional arrangements and co-ordination mechanisms. Each aspect includes specific activities that contribute to an overall system of good EE governance.

Figure 3.3: Energy Efficiency Governance

a. Enabling frameworks

Enabling frameworks confer authority, build consensus, attract attention to and provide resources for EE policy implementation. Important enabling frameworks include laws and decrees, strategies and action plans and funding mechanisms. In many countries, laws and decrees (or directives and proclamations) provide for other governance mechanisms, such as implementing agencies and funding and co-ordination mechanisms. Strategies and action plans comprise the second enabling framework. Some countries use national strategy formulation or an action planning process to engage stakeholders, build consensus and enable energy efficiency measures to be taken. Sometimes the strategy formulation process serves other functions, such as identifying the need for new laws and new institutions. Funding mechanisms are the last – and perhaps most important – enabling framework. Experience from around the world shows that access to adequate, stable and dedicated funding sources is critical for the development of EE organisations and for the professionals that carry out policy implementation.

b. Institutional arrangements

Institutional arrangements constitute the second pillar of energy efficiency governance. This review describes six main types of institutional arrangements: implementing agencies, resourcing requirements, energy providers, public-private sector co-operation, stakeholder engagement and international development assistance. Collectively, these arrangements reflect the broad range of actors that play leading roles in EE policy implementation. Resourcing requirements are an important consideration in making sure that

implementing agencies have the financial and human resources needed to assume their policy implementation responsibilities.

Many types of organisations can be implementing agencies: government energy ministries, specialist clean-energy agencies, energy providers, private and state-owned enterprises and non-profit organisations. There are both advantages and drawbacks for each of these organizational types and the choice of implementing agency should reflect historical development, country context, alignment with sector and EE objectives and the existing institutional map. Public-private sector co-operation ensures that government policies take full advantage of the resources and commercial acumen of the private sector and allows public funding to be leveraged through private investment. Such co-operation also supports market transformation strategies, as new demand for higher efficiency products needs to be satisfied by new products, developed and manufactured by the private sector. Stakeholder engagement is important for building political consensus on policy and implementation strategy and for ensuring that policy deliberations consider a diverse range of perspectives and practical experiences. International development assistance has proven important in establishing EE implementing agencies and in creating other EE governance mechanisms in developing countries.

c. Co-ordination mechanisms

Co-ordination mechanisms include governmental co-ordination mechanisms, targets and evaluation. Creating co-ordination mechanisms both within and across levels of government directly influences the quality and effectiveness of EE policy outcomes. Intra-governmental co-ordination helps avoid overlap and duplication, and allows informed discussions about how best to implement policies. Co-ordination across levels of government enables national governments to devolve implementation responsibility to local authorities, while retaining overall programmatic control. Targets are useful co-ordination mechanisms because they help to motivate policy implementers, track implementation progress and identify the need to make mid-term policy adjustments. Targets can provide a concrete basis for developing multi-year programmes, mobilising funding and identifying agency staffing needs. Evaluation is critical to good EE governance, as it serves to test planning assumptions, monitor overall results, compare programme performance, fine-tune implementation processes and incorporate the lessons learned into future policies and programmes. Evaluation also provides the foundation for oversight and accountability arrangements

4. BARRIERS IN IMPLEMENTATION OF BEEC

The operational building energy efficiency codes (BEEC) require continuous updating along with continuous monitoring of enforcement to transform a country to achieve energy modesty in construction sector.

Implementing bodies / statutory agencies in various developing countries with recent history of implementation of BEEC have identified following key operational shortcomings

These barriers have been essentially qualified on the grounds of:

- Political barriers- Complexity of procedures- Market barriers

4.1 Political Barriers

It has been observed that countries with overall supervision / government oversight on the construction sector as well an established supply chain in terms of engineering capabilities have seen tremendous growth in building compliance rate to requisite performance standards set out in a country.

Lebanon was facing political challenges in past, but now it is observed that the country is aligning itself towards economic growth coupled with sustainable development. Various recent policy developments at the MEW indicate a sound political will to bring about the above said goals.

4.2 Complexity of proceduresThe BEEC with performance-based compliance are more complex and require technical knowhow to understand, implement and monitor. The key of compliance, of a BEEC, remains with statutory bodies like municipal corporations beyond the construction where technical expertise is largely present with the architects and engineers.

With respect to Lebanon, it will be possible to achieve near expected results in a shorter span with minimal complexity, whereas once the systems and policies are in place, the country can graduate to performance based standards for the country.

4.3 Market BarriersIt is well established fact that subsidies distort the market and long term success is always achieved through market driven mechanisms; still in most of

44 | P a g e


the cases, new policy initiatives are supported by incentives and penalties till the market matures. The policy makers should look at the need to move from bad subsidies to good subsidies.

The government of Lebanon as part of LAS-EC framework, has put forth an ambitious target of reducing energy consumption in all sectors with building sector as one the prime area for developmental targets. Although EDL is not able to provide electricity against demand and backup arrangements are the only source for electricity for 40% of the demand, a subsidized tariff is one of the major barriers for the market to look and adopt EE measures.

A country in which service sector is delivering a major portion of the GDP, the cost of energy is generally passed through to the buyers of services, whereas in manufacturing sector, investment on energy has a direct impact on the final product. This difference could be considered as additional bottleneck for EE adoption. EDL and the policy makers will have to play a major role by creating an infrastructure for reliable electricity availability to help market players look at investments in EE measures in building sector.

Adoption of thermal standards for buildings or a holistic BEEC would require availability of tools and testing procedures at the disposal for statutory entities, through third party service providers as well as in-house facilities within the government framework. This would be required to establish checks and balances in the form of financial gains to the investors complying to codes as well as penalties for non-compliance.

To sum up, it can be represented as:

There is a good potential for implementation of BEEC in Lebanon as political will, technical skills as well as growing market would help sustain such initiatives.

Support from developmental setup of Europe and the World Bank is available for taking up both advocacy initiatives as well as implementation plans.

Prescriptive approach is the simplest approach for implementation especially for small buildings which are going to contribute most on under / non compliance because of smaller individual consumption of energy.

LCEC as well as other organizations such as OEA, LIBNOR, IRI, LGBC are already active in the field of energy efficiency. LCEC is also operating at the grass-root level through programs like CFL

45 | P a g e


distribution.

Following action can further help overcome the barriers:

Need to develop compliance infrastructure can be carried out in medium term to support the larger goal of meeting / exceeding international best practices. In due course, the building rating system should be the goal for the country.

Need infrastructure for training installers, engineers and for accrediting assessors and inspectors.

Give market time to anticipate to a new standard and prepare itself for future

Make sure all stakeholders are skilled to ensure proper implementation and this should apply to even the investor / owner of the building to have basic understanding of EE and its benefits.

Government can promote energy efficiency program in buildings through different incentive for all stakeholders (owners, consultants, producers, etc.) in forms such as grants, loans, tax reduction and recognition certification

Raising awareness and improving technical assistance and capacity building.

Improving legal and macroeconomic framework conditions for EE and renewable energy technologies specifically for the technologies with possibility of integration with building envelope

Expanding development partnerships with the private sector (especially Banks).

Need for establishing certified accredited laboratories.

High profile demonstration pilot projects are necessary to propel the community.

Establishing data base on locally available natural and ecological

46 | P a g e


building materials.

While proposing the roadmap, care has been taken to suggest activities and initiatives that help overcome the above mentioned barriers.

5 APPROACH OF ROADMAP FOR IMPLEMENTING BEEC IN LEBANON

The roadmap for BEEC in Lebanon has been essentially proposed considering the fast pace implementation / construction of new buildings in the country vis-à-vis the availability of resources, tools and techniques and preparedness of the country to switchover from the status of no regulation in terms of building EE to a performance based approach.

The existing thermal buildings standards in Lebanon require revision in some of the sections in order to align it to the international best practices. Details of these revisions are provided towards the end of this report in Appendix-2. Integration of thermal standards in present form will have a positive yet limited impact on the EE gains in the building sector, whereas with use of available standardized equipments used in the buildings, a further reduction in energy consumption is possible. It is thus advisable to look at the development of a prescriptive BEEC for the country for quick adoption and easier inspection, which could result in better performance.

The present procedure of approval for building construction requires further strengthening of the technical skill sets for performance based inspection of the buildings.

In medium term, it is targeted that the country would work towards creation of testing facilities; policies for performance monitoring and inspection through trained officials and can look forward to meeting the global standards of BEEC.

The short term target of prescriptive code followed by medium term performance based code is thus suggested in the roadmap for Lebanon. The activity schedule for next 5 years has been prepared and presented in Section 10. Figure 5.1 presents the overview of approach that has been followed for proposing the overall roadmap for BEEC.

6. DETAILS OF SHORT TERM ROADMAPThe approach and major milestones starting from development of code to compliance are shown in the Figure-6.1 given below.

Figure 6.1: From code development to compliance [WB 2010]

The roadmap for Lebanon has been proposed following similar approach.

6.1 Code developmentIt is proposed that the existing TSBL is modified and converted into elemental BEEC. While arriving at the values for various elements such as R value of insulation, SHGC of glass and efficiencies of lighting and HVAC systems, detailed payback analysis should be carried out using energy simulation of typical building typologies. The proposed modifications are detailed in the following sections.

6.1.1 Modification of existing Thermal Standards (TSBL) into Elemental Building Energy Efficiency Code

a. There are two versions of the Thermal Standards for Buildings in Lebanon, namely TSBL 2005 and TSBL 2010. Comparison of both the versions with international best practices suggests that some modifications needs to be carried out and the existing recommendations of TSBL are to be revisited before converting either of them into a code.

Review and comparison of TSBL 2005 and TSBL 2010 is given in Appendix-1, Comparison of TSBL 2005 and TSBL 2010 with international best practices is given in Appendix-2; and recommendations for adopting

TSBL 2005 and TSBL 2010 for developing elemental code and BEEC are given in Appendix -3

b. TSBL 2005 and 2010 cover only the building envelope. As per the recommendations given in Appendix-3, it is recommended to add prescriptive requirements for minimum efficiency in lighting, HVAC equipment and solar water heating. This will help in developing elemental building energy efficiency code. Approach for specifying the minimum requirements for lighting, HVAC equipment and solar water heating systems is given in the subsequent sections.There are two alternatives for bringing in such a feature:

Option-1: LIBNOR defines/modifies the standards for lighting energy efficiency defining minimum energy efficiency of lamps, and maximum permissible Lighting Power Density based upon international practices. In that case BEEC may consider referring to the standards of LIBNOR as requirement.

Option-2: The requirements for the new standards may directly be advised in the BEEC by the committee, stating that in future, if LIBNOR releases any standard in this regard, stringent of the two may be considered.

A technical committee comprising of representatives of major stakeholders and subject matter experts may be constituted to develop the elemental BEEC. The Figure 6.2 below depicts the scope of work for the technical committee.

6.1.2 Specifying Lighting Efficiency through Lighting Power DensityEnergy consumption for internal illumination of buildings using artificial lighting is one major end use of electricity. Energy saving can be ensured by use of efficient fixtures and efficient lighting design. To allow flexibility to the designers, it is suggested to specify in the BEEC, maximum interior lighting power allowance in buildings. Internationally there are two commonly used methods for defining this allowance: building area method, and space function method. In the building area method, aggregated lighting power density of the whole building is not to exceed the LPD values prescribed in a table for various types of buildings. Table-6.1 shows examples of such values following the building area method.

In the space function method; lighting power density for individual type of area within a building are specified. The maximum allowable Lighting Power for the building can be calculated by summing the maximum lighting power for each space where maximum lighting power for each space can be calculated by multiplying the area of the space by corresponding LPD as given in the table 6.2. Table 6.2 shows example of such values following the space function method. It may be noted here that the values provided in Table 6.1 and 6.2 are indicative only and are given as an example. Such target values may be decided by the committee working on the elemental BEEC based upon the values followed in various standards such as ASHRAE, EN etc.

Similar tables can be specified in the elemental building energy efficiency code of Lebanon.

6.1.3 HVAC system efficiencyIt is suggested to specify minimum energy efficiency performance levels for the heating ventilation and air conditioning systems. This can be achieved by specifying the minimum Coefficient of Performance (COP) for cooling and heating equipment of each type. Designer can have flexibility for selection of equipment; however, for any type of equipment, the COP should meet the minimum requirement as per the elemental building energy efficiency code. Sample table for the purpose is given below as Table 6.3:

Table 6-6: Minimum COP values for HVAC systems

Equipment class Minimum COP

4.1 ARI210/240

Unitary Water Cooled Air Conditioner ≥ ≤ 40 kW [≥ 11 tons]

3.22 3.02 ARI210/240

Since a large number of buildings use heating systems, similar to the minimum COP of cooling systems, minimum efficiency of heating systems such as gas heaters and electric heaters should also be defined in the code.

6.1.4 Solar Water Heating

There is already a program going on in Lebanon for promoting use of solar water heating systems in buildings. It is recommended that the requirements of solar water heating systems considering the type of usage, climatic conditions, no. of floors etc. may be added in the elemental BEEC as requirement. Individual houses and low rise buildings would have a possibility of replacing a larger fraction of the conventional water heating systems by solar water heating; whereas, due to limited roof availability, such possibility for high rise buildings would be very limited. To address this difference, and to set realistic targets, following points may be considered:

- Setting up different minimum requirements for residential buildings as per the no. of floors

- Promoting use of common solar water heating facilities in high rise residential buildings, in place of individual family owned systems.

- Setting up separate minimum requirement of solar water heating system capacity for commercial buildings using hot water or steam to support various processes such as laundry, cooking, dish washing.

- Promoting use of concentrating solar collectors in commercial

56 | P a g e


buildings using hot water and/or steam, such as hotels, hospitals etc.

Further, it would be worth mentioning here that considering the use of roof for solar water heating systems, and also due to economic considerations, solar photovoltaic systems have not been recommended for inclusion in the elemental BEEC.

6.1.5 Covering major retrofitting and extension of existing buildings:

Since there are large numbers of existing buildings in Lebanon with a need to reduce their energy consumption, it is proposed that retrofitting of lighting, HVAC systems, or change in envelope parts such as glass may be covered under the BEEC. The retrofitted parts/systems should be compliant with the code. Similarly, extension of buildings should also be required to meet the requirements of BEEC.

6.1.6 Mechanism for short term code development

Since attempts are already underway for making the LCEC as the National Energy Agency in Lebanon, and they have experience of developing TSBL 2005, it is recommended that LCEC takes lead for this purpose and coordinates this activity. On behalf of Ministry of Energy and Water, LCEC should also act as custodian of the BEEC in the country.

It is suggested that representatives of the various stakeholder groups should be involved in defining the requirements of lighting and HVAC system in the elemental building energy efficiency code. Following major stakeholder groups may be involved for this purpose:

a. Research organizations: to incorporate the trends and technology development

b. Suppliers of lighting equipment: to incorporate availability of equipment in market

c. Suppliers of HVAC equipment: to incorporate availability of equipment in market

d. Professional bodies: to incorporate the preparedness of market forces

57 | P a g e


such as professionals, designers, manufacturers, installers

e. International experts: to incorporate the international trends and prevailing norms of energy efficiency worldwide

6.2 Adoption As per the report ‘Energy Efficiency Governance, IEA 2010’ and the ‘National Energy efficiency Action Plan for Lebanon, LCEC 2010’ it has been noted that through the adoption of the Energy Conservation Law, the process of institutionalization of the Lebanese Center for Energy Conservation (LCEC) as the national energy agency for Lebanon has initiated in 2010 as a regulator for energy efficiency in Lebanon. It is therefore recommended that at country level, the LCEC should be given the responsibility, powers and provided with funds through budget/taxes/international funding agencies for implementing this roadmap in collaboration with other agencies as per their domain and expertise.

Once the BEEC is submitted by LCEC to the Ministry of Energy and Water, the Ministry may consider forwarding it to the Council of Ministers as a bill for adoption for Stage-1: Mandatory for government buildings. In order to make the BEEC mandatory for all buildings, the council of Minister may consider forwarding the bill for approval by the parliament for adoption at the national level.

The adoption of BEEC by parliament would authorise the local bodies to enforce the recommendations of elemental code. Without having the code adopted, the local bodies, would not have the necessary authority to force the builders and developers towards such code. Adoption of code also motivates the market and other agencies such as educational and research institutes, professional bodies to enhance their efforts in this direction.

Adopting the BEEC would ensure that all builders in the area are building to the same standard. Without having the code adopted by government, some builders/developers might cut corners to provide a competitive advantage.It is recommended to have adoption and implementation of the code in phased manner as shown in figure 6.3:Stage-1: Mandatory for Government / Public buildingsStage-2: Voluntary for all buildings

58 | P a g e


Stage-3: Mandatory for all buildings

Figure 6.3: Phased implementation of the elemental code

The phased adoption and implementation would help in the following ways:

In the initial phases, there is relatively less ‘know-how’ about new materials and technologies. Also, the materials and technologies are relatively expensive in the beginning. Wider use of technology brings in economy of scale and helps in reducing the costs. Implementation of code on government building would avoid passing on such load of extra cost directly to the public. If required, extra funding for implementation on government buildings may be arranged through international agencies or extra budgetary provisions within the country.

While the code is mandatory for government buildings in the first phase, it can be voluntary for other buildings. Some highly motivated and aware builders might come forward as early adopters of the code. Sometime doing so helps improve their corporate image. This may be treated as second phase and may start slightly after the first phase is launched.

Once there is sufficient ‘know-how’ and the awareness building efforts

6.3 Implementation

Although it is recommended that LCEC on behalf of Ministry of Energy and Water should act as custodian of the BEEC and be responsible for implementation of the entire roadmap, LCEC should coordinate various activities in association with other agencies/institutions as per their respective domain and expertise for successfully capturing the opportunity of energy saving in buildings.

a. Awareness workshops:Awareness about the elemental BEEC, its benefits, implications should be spread through organizing awareness workshops throughout the country, targeting different stakeholder groups. In the successful implementation of the BEEC, outreach plays a very important role. It is necessary that all the stakeholder groups, including developers, and building owners understand the intent of the code and get convinced about various requirements.

Such workshops can be organized by entities such as OEA, and other similar organizations

Print and electronic media can be used to spread the awareness about the benefits of the code to individuals and to the country as a whole.

LCEC has been involved in increasing the awareness about energy efficiency through other ongoing/completed programs such as SWH program, CDM etc. Their experience of conducting awareness campaigns may be utilised to create awareness related to BEEC.

b. Demonstration project:

60 | P a g e


In addition to launching an awareness drive or campaign, following the principle of ‘seeing is believing’, it is suggested to carry-out few demonstration projects. These demonstration projects should demonstrate the following:

- Reduced energy saving in the BEEC compliant building

- Display of energy efficient equipment materials

- Showing the process of meeting requirements of BEEC in the design decision making process

- Showing the process of evaluation of project for compliance checking. This would be especially useful for the representatives of authorities who would be carrying out such evaluations on regular basis.

Some professional body or research organization can be given the assignment of converting the entire process starting from design stage to evaluation and release of compliance certificate, into a case study that can be referred by designers and evaluators in future. Any possibility pertaining to road shows may also be considered for sensitizing the market at the grass root level.

c. Training:For successful implementation of code it is very important that trained manpower is ready at all levels. Large base of trained professionals who can design code compliant buildings is strength of any country. It is equally important that training is imparted at all levels that are involved in the process. Sometimes, lack of training starts creating a negative feeling in various stakeholder groups that eventually becomes a barrier for implementation. It is therefore recommended to conduct training through the following modes:

On site class room training programs Web-based training programs

It is further recommended that first the training modules should be prepared in association with educational institutes that specialise in imparting trainings, and preferably have international exposure and have been involved in the process of development of code.

It has been seen that some countries even take help of international experts in developing training modules and in conducting training programs. However, it is recommended that local trainers or potential trainers are utilized for this purpose with only occasional assistance from international experts as and when required. For this purpose, as done in several countries, first of all ‘train the

61 | P a g e


trainer’ workshops are conducted that provides large no. of trainers and help in conducting large number of training programs throughout the country.

d. Establishing and utilizing enforcement infrastructure, tools, and systems:

As per the international best practices, a computer based tool for checking compliance of BEEC should be developed. There are many computer-based tools and services to help automate and streamline the enforcement process. Some efforts have already been made in this direction for development of a tool for TSBL 2005. It is recommended that either the tool developed for TSBL 2005 should be modified covering modifications or extension of the TSBL, or a new tool may be developed. This tool enables designers and professionals to check their design specifications for compliance, as well as it assists the staff of enforcement agency to check projects fast with a significantly reduced possibility of manual error. Besides being technically correct and tested through variety of cases, it is recommended that such tool should also be ‘easy to use’. For this purpose, a beta version of the tool is to be launched first, and on the basis of comments received from prospective users, modifications should be made to release the final version.

e. Implementation support mechanism: query, clarification etc.,

Since BEEC would be a new document for most of the professionals in Lebanon, it is quite likely that professionals may not fully understand the specifications and requirements. A possibility of requiring issuance of post-release clarifications cannot be ruled out. To cover all such issues, a government agency, preferably LCEC or equivalent neutral body that has been involved with development of code, should be given responsibility to act as nodal agency for answering queries of end users and for releasing interpretation related clarifications.

f. Market transformationDespite having a good code and skilled manpower being present, a supporting market providing required material and equipment at competitive prices is one key factor for success of BEEC. In most cases, new and efficient products face challenge from existing inefficient products through availability of material, availability of spares, and price. In order to curb the barriers for a healthy market for efficient materials and products, following actions may be considered:

62 | P a g e


Launching standard and labelling program

Import duty exemption on efficient products and equipment

Waiver of sales tax or any other tax on efficient product

Discouraging use of inefficient products, through media, notifications etc.

Awarding/rewarding efficient products with subsidies, rebates, discounts

Soft bank loans for code compliant buildings and standard equipment

Energy efficiency CESS: Additional tax on sale of inefficient equipment. The income from this additional tax may be made available for supporting energy efficiency related projects in the country

LCEC has recently been involved in market creation/transformation projects related to solar water heating systems. Lessons learnt from that program may be utilized for transforming the market for energy efficient equipment required for BEEC compliance.

6.4 Enforcement

Enforcement is the process that building inspection departments undertake to ensure that site plans and construction follow the provisions of the energy code. Without a significant emphasis on enforcement, compliance diminishes, and the outcome is always the same: new building or renovation projects that fail to realize their full potential for energy savings.

Following building permit system already exists in Lebanon [CUB Engineering & LCEC 2011]

Elemental BEEC compliance report with supporting documents for large buildings by LCEC-

Figure 6.5: Enforcement of the elemental BEEC

It is proposed to have only the design stage approval as the requirement for compliance. It is especially important to note that the proposed life of the elemental BEEC is just three to four years due to the fact that detailed BEEC would be underway, it is not practical to have pre-occupancy inspection and approval as requirement.

Since the projects first get registered with the OEA, it is proposed that the same agency should be entrusted with the responsibility of checking design stage compliance of the elemental code through LCEC-OEA certified BEEC professionals.

A separate cell may be created at the OEA, which in association with LCEC should be conducting tests for certified BEEC professionals.

This cell may consider conducting training programs and LCEC-OEA certificate test. These LCEC-OEA certified BEEC professionals would be recognized as third party inspectors.

In case of small buildings, compliance report generated using the compliance checking tool would be submitted to the Order of Engineers by LCEC-OEA certified BEEC professionals. Such report from third party professionals would automatically be sufficient for small buildings and no separate design stage approval would be required from the Order of Engineers and Architects.

Random audit of some reports would be carried out in case of small buildings by the joint committee of the OEA and LCEC, to ensure that the declarations issued by qualified BEEC professionals are correct.

In case of large buildings, the Technical department would check entries of compliance report prepared by LCEC-OEA certified BEEC professional through the plans and design documents submitted at the stage of registration. It is proposed to make declaration of conformity with elemental building code by the technical department necessary for issuance of construction permit in case of large buildings.

The promoter/builder/building engineers should be required to declare that the building will be made as per the documents submitted at the stage of registration. In case a deviation is found, some provision of penalty may also be kept to discourage such mismatch. One way of addressing this could be provision of loosing certificate for practice. In case the details used to generate


the compliance report for small building is found to be different from the actual details, the LCEC-OEA certified professional should be losing the BEEC professional certificate.

7. DETAILS OF MEDIUM TERM ROADMAPFollowing the international best practice, it is recommended to develop complete building energy efficiency code encompassing envelope, all the components and equipment used in the building and renewable energy systems.

7.1 Development of codeThe first important step for developing the code is to identify a team for framing the code. A steering committee is to be formed to initiate the building energy code formulation process. The committee can be given clear understanding that the proposed energy code should be decided based on three considerations:

Their energy saving potential Cost effectiveness of the measures suggested Ease of compliance.

The code developers should conduct the financial payback as well as life cycle cost analysis while working out requirements of the code. Such analysis would require knowledge and good understanding of various economic implications in a building, time based variation in performance of recommended equipment/material properties such as aging of cool roof coating, fouling in HVAC equipment, and integration of real life considerations in techno-economic analysis.

The first task of the steering committee would be formulate a work plan for developing the code and identifying key members of its various technical committees and stakeholders in this process. The committee should be supported from a smaller core group to form the working group. The working groups are to be responsible for coordinating day-to-day activities of the building energy code development on behalf of the steering committee. The committees should involve people from research, consulting, manufacturing, promoters, professional societies and administrative segments to truly represent all the stakeholders.

A broad group of relevant stakeholders should be identified by the steering committee to form the Stakeholders’ Panel. This panel should include professional and manufacturers associations, consumer groups, NGOs, central and state government bodies. They should review the code recommendations at intermediate stages, and provide comments to the steering committee.

Technical Committees (TCs) should be setup to provide criterion and minimum standards for energy efficiency in the design or major retrofit of commercial buildings and provide methods for determining compliance with them. Technical Committees would be responsible for developing code components for

efficiency code

Setting up of a National Energy Agency with statutory powers is therefore one important task towards development of code. This agency should involve key organizations/stakeholder groups working in Lebanon, such as the Order of Engineer and Architects, Lebanon Green Building Council, LIBNOR, IRI, GEF, WB, International Finance Corporation, USAID/Amideast. Representatives from

71 | P a g e


research organizations, trade-associations, professional bodies such as ASHRAE may be involved in the effort at different levels.

Once the draft code is ready, it is extremely important to circulate it among wider base of stakeholder groups and keep it open for comments. This not only gives an opportunity to general public to comment on strictness of the code but also help creating an acceptance and a feeling of ownership. Issues such as cost implications and related direct as well as indirect benefits can be discussed on public platforms to enhance the acceptability before the code is given its final form.

7.2 Adoption

Provision should be made for regularly updating the BEEC that is especially required from switching over from elemental code to the complete BEEC.

Due to various limitations, similar to the elemental code, it is suggested to have phased adoption and implementation of the BEEC. Following three phases are suggested:

Phase-1: Mandatory for govt. buildingsPhase-2: Voluntary for all buildings.Phase-3: Mandatory for all buildings.

Justification for the three phases in medium term road map is same as given for short term roadmap.

7.3 ImplementationAlthough it is recommended that LCEC on behalf of Ministry of Energy and Water should act as custodian of the BEEC and be responsible for implementation of the entire roadmap, LCEC should coordinate various activities in association with other agencies/institutions as per their respective domain and expertise for successfully capturing the opportunity of energy saving in buildings.

a. Awareness workshops:Stakeholders associated with the building sector including design, construction, and real estate, legal, financial and property management professionals, as well as those involved in the sale and rental of buildings should be targeted with tailored advice and technical information on how the BEEC will impact on their particular profession. Wider promotion and information campaigns should be launched to introduce and highlight the benefits of BEEC to the public. It is wise to continue information activities after initial implementation as first-time buyers and tenants enter the market

72 | P a g e


continuously. Information should be disseminated through easily accessible sources such as citizens’ advice, local authorities, real estate offices and websites.

Easy access to up-to-date information is an important aspect of keeping industry and the public informed.

Key steps for promoting awareness about BEEC in Lebanon:

Raise awareness among industry and the public

Ensure that all stakeholders have access to relevant information.

Develop ongoing information campaigns that target general public

Following activities are suggested for increasing the outreach and creating awareness about BEEC in Lebanon:

Series of awareness workshops throughout the country

Advertisement campaign in print and electronic media to enhance public awareness and benefits

Participation in related seminars/conferences/trade-shows of related stakeholder groups

Involving national and internal celebrities, talk and promote BEEC in the country

Since this is going to be a big exercise, several organizations such as Order of Engineers and Architects, Universities, Research organizations, and professional bodies such as ASHRAE are to be involved in it.

b. Demonstration project:Worldwide, showcasing the best practice and demonstration buildings has been a very successful tool for encouraging the penetration of energy efficiency measures in the market.

73 | P a g e


Therefore, it is suggested to have demonstration projects spread through-out the country that:

Display the energy savings in real life situation matching with the claims made by the code

Display the use of energy efficient practices related to building envelope design, use of new materials, equipment design and selection

Besides, bringing up the demonstration projects would also help through the following:

Showing the process of meeting requirements of BEEC in the design decision making process to the building professionals such as architects, civil engineers, lighting and HVAC engineers. This may be done through conducting the design charades in various parts of the country involving local building professionals, working together with national and/or international experts having good understanding of the BEEC.

As an integral part of the demonstration projects, the evaluation process also requires showcasing for the benefit of the officers, who would be evaluating the projects in regular course. Hand-holding during the evaluation of initial few projects helps them overcoming the barrier of lack of exposure to the new process.

In addition, such officers may also be sent to some other countries to witness the process of evaluation and to discuss their doubt with their peers who might have faced similar issues and difficulties. The Union of Municipalities may be asked to coordinate such an event.

Some professional body or research organization can be given the assignment of converting the entire process starting from design stage upto evaluation and release of compliance certificate, into the form of a case study that can be referred by designers and evaluators in future. Such case studies can be given shape of a reference guide for designers and evaluators. It is important to note that with passage of time, clarifications and interpretations would be required, and the book of case studies, and reference guide also needs to be updated accordingly.

c. Training:

74 | P a g e


Acquiring the necessary human resources may take time and should be started early. The expertise of those undertaking building assessments is critical to achieve a robust and respected certification scheme. To implement BEEC, a country needs assessors with relevant technical experience. Most countries have a shortage of assessors and need to initiate further training. This initial lack of expertise in the market is one of the most likely factors in BEEC implementation delays. It is essential to undertake a review of existing construction profession capacities and capabilities, undergraduate educational programmes and continuing professional development programmes in order to understand what training is necessary to provide the market with properly qualified assessors.

Availability of expertise directly affects the standards of assessment and the quality of the building rating programme. The extent of training resources required may be dictated by the number of assessors needed to deliver energy certification to the market – and by the availability of qualified experts and developed training material.

Following work is required to be taken up on priority for success of BEEC:

Development of training materials Delivering the training to various professionals and officials

If training modules can be defined and delivered within existing training or undergraduate programmes early in the process, this may help to ensure the availability of highly skilled assessors by the time the scheme is scheduled to become operational. It also has the advantage of utilising existing training accreditation and professional trainers, and may allow for adaptation of existing training material.

It is therefore recommended to conduct training through the following modes:

On site class room training programs Web-based training programs

It is recommended that first the training modules are prepared in association with educational institutes that specialise in imparting trainings, and preferably have international exposure and are already involved in the process of development of code.

It has been seen that some countries even take help of international experts in developing training modules and in conducting training programs. However, it is recommended that local trainers or potential trainers are utilized for this

75 | P a g e


purpose with only occasional assistance from international experts as and when required.

Following nature of training workshops would be required:

Train the trainers workshop Train the teachers workshop Train the evaluators/assessors workshops Train the designers/professionals workshops for on job professionals Training of students: professionals of future

Using the potential of internet, web-based training programs can also be launched. This would be helpful for those who cannot spare few days out of their work for attending the training program. Some tutorials can also be developed explaining key aspects of the code and implementation related issues.

The first three types of training workshops may also include organizing study trips and exchange of experiences with other leading countries. The purpose of such activities is to allow trainers, decision makers and key stakeholders to learn from the successful experiences of countries that have instituted energy conservation policies and programs.

In some countries, technical educational institutes and universities have been provided with literature related to basic fundamentals and applications related to the areas addressed by the BEEC. Funding has also been arranged for purchase of licensed simulation software such as Visual DoE, IES, DesignBuilder etc. Similar approach can be adopted in Lebanon to promote understanding and development of skills among the students.

d. Development of computer toolsUse of computers at every stage of building design, system design, project management, registration at regulatory bodies should be exploited to computerise the process through development / enhancement of the following software tools:

Interfaces and libraries for whole building simulation tools: several tools are already available, there is need to recognize and declare the acceptability of simulation tools results of which would be accepted for compliance. Preference may be given to well established and widely used tools that provide support to users. Local interface may also be developed in local language to enhance usability of the same.

76 | P a g e


Quick analysis tools: some application specific tools such as ‘cool roof calculator’, ‘glazing selection guide tool’ can also be developed to help selection of specifications according to the code.

Evaluation tool for compliance: A separate tool would be required for checking the compliance of BEEC. This tool would be useful at the enforcement agency, as well as for independent third party assessors and processionals working in the field to verify compliance.

It is important to note that besides being technically correct and tested through variety of cases, such tool should also be simple to use.

It is therefore, recommended to develop computer tools of various types for assisting designers, decision makers and evaluators/assessors of BEEC compliance. It may however be noted here, that as of now, there is no publically available weather file for Lebanon in the format acceptable for popularly used energy simulation tools. It will be or upmost importance to collect data from atleast one important location in each climatic zone in Lebanon and prepare weather data file for use in energy simulation tools.

e. Implementation support mechanism: discussion groups, query, clarification, appeal etc.

Since BEEC would be a new document for most of the professionals in Lebanon, it is quite likely that professionals don’t fully understand the specifications and requirements. A possibility of requiring issuance of post-release clarifications cannot be ruled out.

To cover all such issues, a government agency, preferably LCEC or equivalent neutral body that has been involved with development of code, should act as nodal agency for answering queries of end users and for releasing interpretation related clarifications.

f. Setting up test labs

BEEC specifies use of materials and equipment having certain minimum performance level in their prescriptive approach. Even in the performance method of showing compliance of BEEC, properties and performance indicators of materials and equipment are required. It is recommended to set up test labs especially for equipment and materials that are locally produced or manufactured in Lebanon.

77 | P a g e


Following needs to be ensures in this regard:

It is to be ensured that such test labs have an easy and affordable access to producers and manufacturers.

Test labs have continuous up-gradation of facilities as per the technological development

Test labs have some quality control and performance checks Internationally acceptable procedures are followed for the tests

Such test labs would also be useful to launch standards and labelling program for non-voluntary performance of equipment that may exceed the minimum required performance level. Presence of test labs would be useful for effective implementation of BEEC

Presently, the Industrial Research Institute (IRI), is major test lab in the country. However, their existing focus is on safety related testing of equipment and materials. The institute is already bringing up the facility for testing of solar water heating systems. In order to support BEEC, addition of new facilities/labs would be required for testing of thermo-physical parameters and energy efficiency.

g. Market transformationDespite having a good code and skilled manpower being present, a supporting market providing required material and equipment at competitive prices is one key factor for success of BEEC. In most cases, new and efficient products face challenge from existing inefficient products through availability of material, availability of spares, and price. In order to curb the barriers for a healthy market for efficient materials and products, following actions may be considered:

Launching standard and labelling program Import duty exemption on efficient products and equipment Waiver of sales tax or any other tax on efficient product Discouraging use of inefficient products, through media, notifications

etc. Awarding/rewarding efficient products with subsidies, rebates,

discounts To support the reduction in cost by economy of scale

h. Standards and labeling program:

Standards and labels are used to create a market pull by adopting approaches such as energy star rating of lamps, air-conditioners and other, appliances through labeling program. More star indicating more efficiency. Such measure

78 | P a g e


is very successful in creating public awareness about energy efficiency of lighting. Similarly, labels indicating performance of building material and products such as fenestration would also be useful in creating a market pull besides making the technical specifications available for compliance checking.

As per NEEAP-2010, the program for promotion of energy efficient equipment is already going on since 2009. This initiative aims to promote the use of energy efficient equipment in households and commercial buildings. This includes focusing on electrical equipment and establishing a national energy efficiency standard. The program for promotion of energy efficient equipment under the NEEAP-2010, may be strengthened and extended to provide standards and labels for various types of equipment, materials and products required for buildings with reference to whole building approach based BEEC.

It is further suggested that the financing mechanisms and incentives, as also mentioned in the National Energy Efficiency Action Plan for Lebanon, [LCEC-2010]] are launched to promote the use of energy efficiency. This is mainly linked to the collaborative work with the Ministry of Finance and the Central Bank of Lebanon. Experience of the initiative to promote solar water heaters in buildings and institutions in Lebanon may be used in this regard for working out subsidies.

7.4 EnforcementEnforcement is the process that building inspection departments undertake to ensure that site plans and construction follow the provisions of the energy code. Without a significant emphasis on enforcement, compliance diminishes, and the outcome is always the same: new building or renovation projects that fail to realize their full potential for energy savings.

Enforcement systems depend on the type of building regulation that is used. If building efficiency is a part of the general building codes and rules for buildings it will often been forced in the same system as other requirements in the building codes. If the code is set in a specific standard it may be decided to leave the control up to a specific system for energy efficiency or to combine this with other types of control. In many cases, it is up to the local authority to control the compliance on building regulations.

Both systems have advantages; if the control is combined with that of other building regulations this will typically imply systems to deny buildings to be taken into use or other sanctions which also apply for safety reasons etc. But, on the other hand, if compliance is controlled by energy efficiency specialists this may ensure that these controllers have the necessary knowledge. In some countries control of efficiency is based on accreditation systems where responsible experts can loose the right to construct or to apply for permits if the rules are violated.

79 | P a g e


The existing building permit system has already been explained in the ‘enforcement’ section of the short term roadmap. Based upon the study of existing system, following enforcement mechanism is proposed for the BEEC:

80 | P a g e

It is proposed to have two stage approvals as the requirement for compliance: one- design stage approval, second the pre-occupancy approval as shown in the flow chart below.

Conformity with Performance BEEC for large buildings

Performance BEEC compliance report by LCEC-OEA certified BEEC professionalPerformance BEEC compliance report with supporting documents for large buildings by LCEC-

Figure 7.2: Enforcement of the performance BEEC

Request for BEEC compliance

Site inspection for compliance with BEEC

It is proposed to keep the procedure upto the construction permit same as proposed in the short term roadmap. In addition to the design stage approval, pre-occupancy approval is proposed as one additional requirement in the enforcement of detailed BEEC.

For the pre-occupancy approval, the following procedure is proposed:

- For small buildings, LCEC-OEA certified BEEC professionals would conduct third party inspection and submit report to the technical department which conducts the other inspections after once the building is ready. Approval by third party inspector would automatically be sufficient for this purpose.

- Random audit of some small buildings would be conducted by the joint committee of Order of Engineers and Architects and LCEC to ensure that the declarations issued by certified BEEC professionals as third party inspectors are correct.

- For large buildings, the Technical Department would conduct inspection of buildings and issue BEEC compliance certificate which is proposed to be a mandatory requirement for issuance of occupancy permit.

7.5 Compliance trackingUnless code compliance is measured, it is difficult to make improvements, understand where gaps exist in education, and account for related energy savings. The advantage of having the enforcement of BEEC done through local municipal level bodies is that it is relatively easy to track compliance since they anyways keep record of the construction taking place in their jurisdiction. Review of compliance should be done on annual basis and reasons for non-compliance need to be discussed with stakeholder groups. This not only helps identifying the measures required for improving the compliance rates, but sometimes, also provides feedback for modification in the code.

In case of Lebanon, tracking of BEEC compliance may be started after completion of one year from the time when BEEC becomes mandatory for all buildings. It may be done through periodic survey and sampling studies conducted by independent agencies in different parts of the country covering various types of buildings..

8. CLEAN DEVELOPMENT MECHANISM

Clean Development Mechanism is one of three flexible mechanisms under the Kyoto protocol that permits reduction of GHG as a flexible environmental investment and credit scheme of its kind, providing standardized emissions offset instrument, CERs.

The Intergovernmental Penal on Climate Change (IPCC) reported in its fourth assessment that the building sector has the largest potential for significantly reducing GHG emissions but also confirmed that the potential so identified is independent of the cost per ton of CO2 equivalent achieved.

The due diligence of the projects can be carried out depending upon the possibility of replication and transaction expenses required for the interventions. It has been observed that large sized conditioned spaces (essentially Government / public buildings, malls and cinema halls) with significantly high space heating / cooling loads can consider development of standalone CDM projects, whereas smaller interventions with possibility of replication at a larger level may consider programmatic approach for development of CDM projects.

The CDM project cycle is detailed below in the Figure 8.1:

83 | P a g e


Figure 8.1: CDM project cycle

The building sector can essentially exploit following opportunities to develop CDM project:

Heating Ventilation and Air conditioning (HVAC)

Energy efficient lighting (Use of CFL / LEDs in place of incandescent lamps)

Thermal insulation in buildings (Glazing etc)

Building management systems (Human occupancy sensors, load management devices etc)

Supporting devices (Variable frequency drives etc)

Development and implementation of BEEC (covering these suggested interventions) has been advocated for Lebanon in this report and the efforts proposed to be carried out to reduce the operational energy cost over the building’s life cycle can further be brought down by carrying out CDM due diligence of the initiatives and registration of the projects with UNFCCC.

The second important aspect is to consider the financial implication of developing a CDM opportunity which would have the following important component

Advisory fee for development of Project Design Document (CDM PDD)

Designated National Authority (DNA) approval (No fee is levied at present)

Fee for validation of the PDD by UNFCCC accredited Designated Operational Entity (DOE)

Registration fee of UNFCCC (if the estimated annual GHG reduction from the project is in excess of 15,000 tCO2e)

Fee for verification of the project performance by UNFCCC accredited DOE

Transaction expenses (Legal & CER issuance)

84 | P a g e


Taxes (as prevailing in Lebanon)

It has been generally observed that projects / interventions with less than 10,000 tCO2e/year (CERs) are not profitable enough and do not add to the bottom-line of investment required to develop CDM project and carry out transactions during its crediting period at the prevailing price band between Euro 10 – 14 /CER.

8.1 Approach & Methodology

The building sector essentially consumed secondary energy (electricity) for meeting the equipment demand and space conditioning. The estimation of possible GHG emission reduction for electrical energy efficiency can be attributed to the emission factor of the grid from which the electricity is consumed and to the back-up units operating on fossil fuel.

The grid emission factor (CO2 emission) for Lebanon is approximately 0.815 kg/kWh (based on the operational power stations in the country) of electricity whereas for fossil fuel, an average of 2.5 – 2.75 kg CO2 /Litre may be considered for estimation of GHG reduction from energy efficiency interventions in the buildings.

The business decision of development of CDM projects should thus be based on the back of envelope calculations and expected price of the commodity (CER). A CER is equivalent of 1 ton of emission reduction.

The interesting observation specific to the building sector projects (whether standalone or program of activities) is that most of them qualify under the small scale projects for which UNFCCC has approved methodologies which can be straightaway used in development of a candidate CDM project.

In addition to this, for specific interventions, seeking deviation in the existing approved methodologies as well as proposing a new methodology is permitted and once approved by the methodology penal of UNFCCC; the same may be applied for development of PDD.

LCEC is involved in distribution of Compact Fluorescent Lamps (CFLs) in the country in an attempt to reduce energy consumption in building sector; the bulb distribution projects developed as small scale CDM initiatives in the country (after registration with UNFCCC) can help bridge the gap between the price of incandescent lamps and CFL. It is possible to register such projects with

85 | P a g e


UNFCCC until the baseline of the country becomes CFL i.e. every new CFL replaces a CFL.

Similarly HVAC consumes a major portion of electricity in buildings and there is a possibility of considerable savings by improving the coefficient of performance of HVAC both in the case of small units as well as central HVAC units for large buildings can possibly become a good case for CDM project development.

Law 775 of the country which essentially permits IPP for self consumption may also be developed as potential CDM projects where HVAC can be coupled with power generation units implemented for the large building loads (cluster of buildings) and thus this efficient form of electricity generation with almost free HVAC can become a potential project.

8.2 Assurance of revenueAlthough CDM is a flexible mechanism with voluntary participation from the developing countries; the projects developed as CDM opportunities does not guarantee revenue generation for the investor for the following three reasons.

Project baseline Project additionality Common practice

The project baseline plays an important role in estimation of the potential of GHG emission reduction from the project against the Business-as-usual (BAU) scenario. The project baseline is the difference between energy consumption of the base building (without EE interventions) and the proposed building (with EE intervention). The GHG emission reductions from the project are monitored continuously throughout the crediting period of the project. It is important to note that CDM revenue is permitted for a fixed period (10 years or 7 years with possibility of 2 renewals) from the date of registration of project with UNFCCC or from the date of start of operational life of the project, whichever is later and not for the complete life span of a building.

The additionality is another important aspect of the project wherein the EE intervention proposed for a building / set of buildings covered in a program should have viability gap (as compared to the BAU building). The viability gap can be established against the benchmark returns from the investment in BAU and proposed case through financial modelling. It is important for projects in Lebanon to carefully examine the project additionality before attempting CDM registration because the country is dependent upon fuel imports and thus high fuel cost can considerably reduce the investment payback making interventions viable on standalone basis.

86 | P a g e


Common practice will have an impact on CDM registration of a project if projects of similar nature are operating in the region without CDM revenue support. This could be detrimental if projects with viability gap are implemented without CDM registration. If such a situation prevails, the project is required to establish as to how the candidate project is different from other operational projects without CDM registration.

8.3 Important aspects of CDM

CDM project registration is quite rigorous yet very transparent process and involves representation of host country as well as third party independent validation before the project is submitted to the CDM Executive Board with request for registration.

Lebanon ratified the Kyoto Protocol on 11 February 2007 through law 738 dated 15 May 2006. In the year 2006 & 2007, an internal desk study was conducted to establish the DNA process in Lebanon & estimate the potential of CDM. The country adopted single ministry model (which is also practiced internationally) to clear CDM projects based on the sustainable development guidelines of the country. In May 2007, MoE was appointed by the Presidency of the Council of Ministers as the Designated National Authority (DNA) for Lebanon.

At present the DNA in Lebanon is represented by Ms. Rola Sheikh (Department of Air Quality, Lazarieh Centre, 8th Floor, Block A4 New P. O. Box 11-2727 Beirut, Lebanon). All candidate CDM projects are required to be cleared by the DNA before approaching the CDM Executive Board.

To further streamline the process in order to establish seriousness of CDM consideration, the UNFCCC has issued guidance for developers of CDM projects to inform UN within 6 months of start date of project activity about the proposed CDM project. This guidance applies to all the projects conceived after 2 August 2008.

A local and global stakeholder consultation process is also being carried out before a project is validated by a DOE. The process essentially covers the aspects around sustainable and inclusive growth of the community along with economic activities. The local stakeholder consultation is required to be completed before filing the PDD with the DNA and DOE whereas global stakeholder consultation is carried out as a part of the validation exercise.

The CDM project development should be started before project implementation. Ideally the project should be implemented only after CDM registration so as to ensure revenue stream from transaction of GHG emission reduction. For

87 | P a g e


projects with longer gestation period, the registration of the project should get over before the commercial operation date of the project. The average estimated registration time of CDM projects with UNFCCC is about 12 months from the date of preparation of PDD.

LCEC has informed UNFCCC about 6 projects of CFL distribution which are at different stages of development. In addition to this, there are few private sector players developing CDM projects from within Lebanon. A proactive approach by the investors as well as Government can provide the much needed push in development of CDM opportunities available in this sector.

Agencies like IFC are playing pioneering role across the global by securitizing CDM revenue through forward transaction and upfront payment to the investor. This has been a successful model in many countries and a win-win proposition for the investor as well as CER buyer with risk hedging as well as liquidity in the market.

88 | P a g e


9. CONCLUSIONTo implement the comprehensive set of suggestions proposed in this roadmap, the government of Lebanon will need to put in place a short term and a medium term plan. As there is an urgent need for implementing mandatory codes for taping the energy saving opportunities through covering the current construction activities in the country, this roadmap proposes the following short term measures:

1. Modify the current TSBLs to include energy efficiency in lighting and HVAC and also incorporate solar hot water systems. This will ensure that the new elemental building energy efficiency code, enhancing TSBL would cover the envelope, equipment and use of renewable energy in the scope of building scope and have more holistic approach towards building energy efficiency. The elemental code should be prescriptive in nature and easy to implement.

2. This elemental code can be first made mandatory in the government and public buildings followed by mandatory status for all buildings in about 1.5 years from the start of implementation of the recommendations of this roadmap.

While the short term roadmap is being implemented, preparations can be started for implementation of elements of the medium term roadmap for building energy efficiency code. The implementation of short term roadmap will bring in more awareness in the building sector and lay down the process of enforcement of code and start the market transformation for promoting energy efficient products in Lebanon. It will also initiate the capacity building process among all stakeholders.

The medium term roadmap proposes to develop and implement a whole building performance based BEEC. This will be in line with the international best practices and would provide maximum design flexibility by offering tradeoff between all aspects of energy efficiency in the buildings. It is proposed that all the supporting infrastructure and processes which include but not limited to capacity building, training, testing facility, legislative infrastructure, weather data, compliance tools, market transformation are initiated before the comprehensive BEEC is mandated and are in place when it becomes mandatory for all buildings in Lebanon. It is proposed to mandate comprehensive BEEC in phases and be mandated for all the new buildings in less than five years from the start of implementation of the short term roadmap.

APPENDIX 1- COMPARISON OF TSBL 2005 AND TSBL 2010 WITH INTERNATIONAL BEST PRACTICES

International Best practices

TSBL2005 TSBL 2010 Recommendation

Whole building scope

X It is based on thermal cooling/heating energy requirements, and addresses only the envelope of buildings.It only addresses the thermal loads and not fuel and cost of primary energy required to meet the loads.

X It is based on thermal cooling/heating energy requirements, and addresses only the envelope of buildings.It only addresses the thermal loads and not fuel and cost of primary energy required to meet the loads.

Both the standards don’t address the whole building. A lot of fuel is imported in Lebanon, electricity is subsidized and the supply of electricity is intermittent leading to widespread use of on-site diesel operated electricity generators as back-up that are usually expensive to run. The common metric for the whole building approach would hence be very important.

Addressing climatic variation

√ It addresses the climatic variations. However, TSBL-2005 does not split of climatic zone-1 in two sub-categories.

√ In TSBL-2010, the climatic variation in addressed. Climatic zone 1 is split as 1A and 1B, whereas the requirements for envelope as mentioned in the TSBL-2010 are common for these sub-zones are identical.

Split of climatic zone in sub-categories in 1A and 1B to be retained as in TSBL 2010. However, requirements for these sub-categories should be revisited.

Addressing residential and commercial

as low-rise and high-rise.

Specific calculation structure

√ In TSBL 2005, the compliance through performance path can be achieved if the computed annual thermal energy needs of the proposed building is less than computed annual thermal energy needs of the reference building in kWh/sqm/yr. The reference building is similar to the proposed building except that the building envelop components should comply with the requirements of the individual component approach of the prescriptive path. The Reference Building thermal energy usage is the total heating and cooling energy requirements in kilowatt-hours [kWh] determined by the building simulation software using the same inputs as the reference

X In TSBL 2010, compliance through performance path is achieved if the computed annual specific thermal energy needs (cooling and heating) of the proposed building is less than Reference annual specific thermal energy needs [cooling and heating] of same category of building in the specified climatic zone (kWh/m2.year). Further, Simulation Parameters related to occupancy and usage of the building are not fixed but shall be justified according to ASHRAE Fundamentals Book. As per international best practices this is not very desirable in a code, especially for new buildings. This method is more appropriate for existing buildings and these

specific energy targets are based on measured performance of existing buildings. Further, it is desirable that these targets are different for different types of buildings such as hotels, offices, malls etc. TSBL- 2010 has only two building categories i.e. residential and non-residential.

Calculation procedure

√ A compliance tool was developed for TSBL-2005. This tool is specific for TSBL-2005 compliance and hence is on the similar lines as per international best practices

X For TSBL-2010, as of now, similar tool does not seem to be available.

The compliance tool developed for TSBL2005 may be updated or enhanced for use in short term plan to include proposed prescriptive requirements for lighting, HVAC, SWH etc.. For medium term plan, separate tool, covering whole building approach may be developed.

defined to follow the international best practices.

Staged implementation

√ The development of TSBL-2005 seems to be on the similar lines as international best practices, starting from thermal requirements that can be extended to fully integrated energy performance code.

√ The development of TSBL-2010 seems to be on the similar lines as international best practices, starting from thermal requirements to fully integrated energy performance code as shown in Appendix-1.

Since there a spurt of construction activities in Lebanon, it might be better to speed up the staged implementation of BEEC and go for whole building energy efficiency based code at the earliest. This will allow Lebanon to capture the potential of energy savings in all the upcoming construction works.

Mandatory compliance

X Currently TSBL2005 is not a mandatory standard.

X Currently TSBL2010 is not a mandatory standard.

TSBL should be made mandatory as per international best practices. It is a very crucial exercise at this juncture and mandating the code will really

104 | P a g e


help in achieving a larger penetration of code which in turn would yield energy savings for the country. Either the thermal code should be mandated in short term or simple building energy code addressing the envelope, HVAC, lighting, and SWH system through prescriptive approach should be developed and mandated. In medium term, whole building BEEC can be targeted for being mandatory.

Thorough enforcement procedure

X As per available documents enforcement procedure for TSBL is not yet developed.

X As per available documents enforcement procedure for TSBL is not yet developed.

The introduction of a mandatory building energy codes would require the establishment of a verification check at the building permit phase, at the building construction phase, and at the pre-operation phase. The process has not been established as yet in Lebanon. As per the best practice, the enforcement of code would require a holistic approach in tandem with operational agencies at all the phases

105 | P a g e


Penalties for lack of compliance

X As per available documents penalties for lack of compliance have not been spelled out. TSBL 2005 is still not mandatory.

X As per available documents penalties for lack of compliance have not been spelled out. TSBL 2010 is still not mandatory.

Since the enforcement procedure for TSBL is not yet developed in Lebanon, provisions of penalties should be planned for the medium term implementation. The carrot and stick approach has given better results in almost all parts of the world where initial handholding to the new regimes are provided to incentives schemes [favorable policies], recognition followed by corrective actions through penalties and allied controlling measures.

Track compliance rates

X As per available documents mechanism for tracking compliance rates has not been spelled out.

X As per available documents mechanism for tracking compliance rates has not been spelled out.

As per international best practice, a mechanism for tracking compliance rates should be defined for TSBL/BEEC.

Code training and certification

X The available documents do not show a well planned, systematic, multi tier training and certification program for TSBL2005.

X The available documents do not show a well planned, systematic, multi tier training and certification program for TSBL2010.

In most countries, induction of the code and related skills in the academic curriculum has helped a great deal in developing trained manpower. The channel can be established in Lebanon for rigorous training of professional through any of the operational regulatory / statutory bodies responsible for building

106 | P a g e


approvals.

Voluntary high performance incentive programs

X TSBL-2005 is silent about voluntary high performance incentives.

X TSBL-2010 is silent about voluntary high performance incentives.

Some of the voluntary programs for high performance buildings are already present in Lebanon. The Lebanon Green Building Council [GBC] is an independent body and is working towards Lebanese applicable certification and labeling of buildings. This is in line with international best practices. However, some additional incentives can be floated through the TSBL or BEEC.

Demonstration projects

X The available documents do not show plans for showcasing TSBL2005 through demonstration project.

X The available documents do not show plans for showcasing TSBL2010 through demonstration project.

Demonstration projects would be required for TSBL to document the design process including design discussions and decisions, together with the evaluation and approval process.

APPENDIX 2- REVIEW AND COMPARISON OF TSBL 2005 AND TSBL 2010

General observations:

S.No

Observations Reference Recommendations

1. Multilevel numberingThe document has bulleted points and unnumbered sections at several places. It becomes difficult to cite any specific section or bulleted point. Use of multilevel numbering throughout the document might be useful.

-- Multilevel numbering to be followed in the further development of standard.

2. Standard test proceduresStandard test procedures for determining the properties such as U-value of glass, insulation, etc. are not mentioned in either of the codes. To avoid ambiguity, standard test procedures followed by the country/internationally may be mentioned in the code.

-- Standard test procedures for determining the properties such as U-value of glass, insulation, etc. should be mentioned.

3. Trade-off methodIn TSBL 2005, section 6.2 ‘Compliance with the Thermal Transmittance using the Overall Envelope Approach’ gives the trade-off approach. This approach is part of prescriptive path. The overall envelope approach permits trade off between building envelope components, and as such provides more building design flexibility.In TSBL 2010, section 6, the trade-off method is a separate

Page-7, TSBL 2005

Page 8, TSBL 2010

Trade-off method as give in TSBL 2005 can be adopted for further development. Trade off method should be part of prescriptive approach

109 | P a g e


compliance path. There are three compliance path in TSBL 2010- prescriptive option, trade-off option, performance option. Technically both the codes have similar approach for trade-off method, except that in TSBL 2005 it is part of prescriptive approach, and in TSBL 2010 it is a separate option.

110 | P a g e


Comparison of TSBL2005 and TSBL2010 related to prescriptive and trade-off method:

S.No

Observations Reference Recommendations

1. TSBL2010 uses the term ‘Cooling/heating thermal energy requirement/need’. At several places, term ‘Cooling/heating energy requirement/need’ is used. It will be helpful if the terms used are consistent throughout the document and are clearly defined in the code since one of the best practices for building energy efficiency codes is ‘not to have any ambiguity in interpretation’.

TSBL-10, Page-2, last point.TSBL-10, Page-6, para-3. TSBL-10, page-15, section 7.1: ‘Compliance’

Consistency in the terms to be ensured.

2. Climatic sub zone 1A, 1BIn TSBL-2010, Table-2 shows that climatic zone 1 is split as 1A and 1B, whereas the requirements mentioned in the TSBL-2010 are common for these sub-categories. TSBL-2005 does not split of climatic zone-1 in two sub-categories.The climatic zone-1 is split into two sub-zones based upon altitude, wherein 1A is applicable for altitude less than 400m, and 1B is for altitude greater than 400m. The main difference between these two sub-zones is the intensity and duration of winters. 1A has warm and short winter and 1B

TSBL 2010Page-6, Table-2

Requirements for building envelope for sub-zones 1A and 1B should be revisited.

111 | P a g e


has cold and long winter that increases with altitude. However the requirements for envelope in these two sub-zones are identical. This may be revisited.

3. Location of insulation above/below deck.Section 6.1 of TSBL 2010 specifies the maximum reference U-values for roofs, walls, glazing and exposed and semi-exposed floors for the four climatic zones and two building categories viz. Residential and non-residential. Similar table [having different values] is given in TSBL-2005 under section 6.11.However, the code is silent for placement of insulation especially for the roof i.e. over deck or under deck. As per the best practices for energy efficiency, placement of insulation is done as per the climatic conditions. To reduce ambiguity it will be helpful if the code clearly specifies placement of insulation with respect to the deck.

TSBL 2010, Page-8, section 6.1

Over-deck insulation may be recommended for cooling dominated zones, whereas under-deck placement of insulation is recommended for heating dominated zones.

4. Roof insulation for climatic zonesIn TSBL-2005 Table-2, reference thermal transmittance values are given for roof.

TSBL 2005 Page-6, Table-2

The values for TSBL 2005 were arrived at much before the values of TSBL 2010. Also the payback analysis must

112 | P a g e


According to this table, for both the building types in Zone-1,2,3 thermal transmittance values are same i.e. 0.57W/m2K. For zone-4, this value is 0.44W/m2K for both the building categories.In TSBL-2010 Table-3, value for climatic zone-1, non-residential building category is 0.71 W/m2K, and value for non-residential building in Zone-2,3,4 is 0.55 W/m2K.It is observed that not only the values are different in TSBL-2005 and TSBL-2010, but the trend of the values is also different. This may be revisited.

TSBL 2010 Page-8, Table-3

have been done based on the cost of electricity and materials prevailing at these times. Further, both the codes are addressing only the thermal energy aspect of the building the equipment efficiencies considered might not be same as the efficiencies that might be mandated in the proposed elemental code. Hence it is recommended that these values be revisited after the equipment efficiencies are included in the elemental code

5. Maximum allowable WWR in cold zone:TSBL-2010 puts a restriction on maximum allowable WWR for all the building categories in all the climatic zones. TSBL-2005 also puts such a restriction. In TSBL-2005, the maximum reference effective fenestration ratio in Zone-4 [high mountain] is 21% for non-residential buildings as compared to 10-13% in other zones. In TSBL-2010, the values in all the zones ranges between 19-21%. Rather the value in zone-4 [high mountain] for non-residential is 0.2 and in zone-1 for non-residential is 0.21. The values in TSBL-2010 and 2005 are different and the trend also seems to be different. This may be revisited.

TSBL 2005, Page 10, Table-8,

TSBL 2010, Page 13, Table-9,

Before finalization of the standard, a simulation based exercise may be carried out [with combined thermal and lighting analysis] to make sure that the recommendation are based on the current costs and include the efficiency of lighting and HVAC.

Use of term WWR is recommended for this purpose as done in TSBL 2010.

113 | P a g e


6. Architectural shading factor:TSBL 2010 gives the architectural shading factor for windows protected by overhangs only, fins only, both fins and overhangs in Tables 6,7,8. TSBL 2005 also gives the architectural shading factor for windows protected by overhangs only, fins only, both fins and overhangs in Tables 5,6,7. However, the categories of projection factor [PF] for which the architectural shading factor [ASF] is given, as well as values of the architectural factors in both the codes are significantly different. Snapshot of ASF for overhangs only in TSBL-2005:

TSBL 2005, page 9, Table 5,6,7

TSBL 2010, Page 12,13, Table 6,7,8

This difference between the two standards needs to be revisited.

114 | P a g e


The above is the snapshot of ASF for overhangs only in TSBL-2010. The values of ASF for overhangs, fins and combination of overhangs and fins may be revisited.

7. Maximum WWRAs per TSBL-2010 the prescriptive and Building-Envelope Trade-Off path cannot be used when the proposed building has a window to gross wall ratio greater than 45%, or when the proposed building has a skylight to gross roof ratio [the gross roof area is inclusive of the skylight area] greater than 5%. The performance path should be used in these cases.Whereas, as per TSBL-2005 the prescriptive path cannot be used when the proposed building has a window to gross wall ratio [the gross wall area is inclusive of the window area] greater than 0.30, or when the proposed building has a skylight to gross roof ratio [the gross roof area is inclusive of the skylight area] greater than 0.05. The performance path should be used in these cases.The increase in limit from 30% to 45% may be revisited.

TSBL 2010, Page 7, last para

TSBL 2005, Page 4, last para

The values for TSBL 2005 were arrived at much before the values of TSBL 2010. Also the payback analysis must have been done based on the cost of electricity and materials prevailing at these times. Further, both the codes are addressing only the thermal energy aspect of the building the equipment efficiencies considered might not be same as the efficiencies that might be mandated in the proposed elemental code. Hence it is recommended that these values be revisited after the equipment efficiencies are included in the elemental code

8. Provision of cool roof:In both the standards TSBL-2005 and TSBL-

In cooling dominated climatic zones, high albedo roof (cool roof) may be

Comparison of TSBL-2005 and TBL-2010 for performance method:

S.No.

Observations Reference

1. In TSBL 2005, the compliance through performance path can be achieved if the computed annual thermal energy needs of the proposed building is less than computed annual thermal energy needs of the reference building in kWh/sqm/yr as given in section 7.3. The reference building is similar to the proposed building except that the building envelop components should comply with the requirements of the individual component approach of the prescriptive path. The Reference Building thermal energy usage is the total heating and cooling energy requirements in kilowatt-hours [kWh] determined by the building simulation software using the same inputs as the reference building, including the same weather files and fixed simulation parameters which have been approved by the competent Lebanese authority. In TSBL 2010, compliance through performance path is achieved if the computed annual specific thermal energy needs [cooling and heating] of the proposed building is less

than Reference annual specific thermal energy needs [cooling and heating] of same category of building in the specified climatic zone [kWh/m2.year] as given in section 7.2. Further, Simulation Parameters related to occupancy and usage of the building are not fixed but shall be justified according to ASHRAE Fundamentals Book.Approach of TSBL 2005 is on the lines of international best practices. The performance path of TSBL 2010 is based on specific energy targets, this method is generally applied to existing buildings. For simulation parameters, TSBL 2005 refers to competent Lebanese authority, whereas, TSBL 2010 standard refers to ASHRAE Fundamental Book for various parameters.

2. Simulation softwareIn TSBL 2005, under the section 7.2, it is mentioned that the list of approved software packages will be established by the relevant National Institution. From then, any of the approved software packages can be used for the calculation of the expected total annual energy requirements for heating and cooling for the proposed and reference buildings.In TSBL 2010, under section 7.1, it is

TSBL 2005, Page 12

The list of the approved software should be clearly mentioned and it should cover several commonly used software worldwide.

118 | P a g e


mentioned that the list of approved software packages will be established periodically by the Order of Engineers and Architects and LIBNOR. From then, any of the approved software packages can be used for the calculation of the expected total annual thermal energy requirements for heating and cooling for the proposed buildings. Whereas, in the compliance form on page-44, names of seven software are listed. It is not clear if these software are approved by the Order of Engineers and Architects and LIBNOR.

Observations Reference

1. Compliance toolsA compliance tool was developed for TSBL-2005. This tool is specific for TSBL-2005 compliance and hence is on the similar lines as per international best practices. For TSBL-2010, as of now similar tool does not seem to be available.

It is recommended to continue the development of the tool developed for compliance for TSBL 2005 and include the proposed prescriptive requirements for lighting, HVAC etc

2. Compliance formsAnnexure-5 gives the compliance forms for TSBL-2010. No such forms are available for TSBL 2005.

APPENDIX 3- RECOMMENDATIONS FOR ADOPTING TSBL 2005 AND TSBL 2010 FOR DEVELOPING ELEMENTAL CODE AND BEEC

Based on the comparison of TSBL 2005 and TSBL 2010 with international best practices, some recommendations have been arrived at. Some of the recommendations are related to the development of the code and are technical in nature. Others are related to the implementation of the code. Recommendations regarding implementation will be discussed in details in the roadmap to be provided later by PwC consortium.

1. Both the standards don’t address the whole building. A lot of fuel is imported in Lebanon, electricity is subsidized and the supply of electricity is intermittent leading to widespread use of on-site diesel operated electricity generators as back-up that are usually expensive to run. The common metric for the whole building approach would hence be very important.

2. Split of climatic zone in sub-categories in 1A and 1B to be retained as in TSBL 2010. However, requirements for these sub-categories should be revisited.

3. It might be helpful if the standards consider further classification such as low-rise and high rise.

4. Specific calculation structure of TSBL 2005 is on the lines of international best practices. The performance path of TSBL 2010 is based on specific energy targets, this method is generally applied to existing buildings. Hence it is recommended to follow the approach given in TSBL 2005.

5. The compliance tool developed for TSBL2005 may be updated or enhanced for use in short term plan to include proposed prescriptive requirements for lighting, HVAC, solar water heating etc. For medium term plan, separate tool, covering whole building performance based approach may be developed.

6. An updating mechanism can be defined to follow the international best practices.

7. Since there a spurt of construction activities in Lebanon, it might be better to speed up the staged implementation of BEEC and go for whole building energy efficiency based code at the earliest. This will

121 | P a g e


allow Lebanon to capture the potential of energy savings in all the upcoming construction works.

8. TSBL should be made mandatory as per international best practices. It is a very crucial exercise at this juncture and mandating the code will really help in achieving a larger penetration of code which in turn would yield energy savings for the country. Either the thermal code should be mandated in short term or simple building energy code addressing the envelope, HVAC,lighting and solar water heating through prescriptive approach should be developed and mandated. In medium term, whole building BEEC can be targeted for being mandatory.

9.

The process has not been established as yet in Lebanon. As per the best practice, the enforcement of code would require a holistic approach in tandem with operational agencies at all the phases

10.Since the enforcement procedure for TSBL is not yet developed in Lebanon, provisions of penalties should be planned for the medium term implementation. The carrot and stick approach has given better results in almost all parts of the world where initial handholding to the new regimes are provided to incentives schemes (favorable policies), recognition followed by corrective actions through penalties and allied controlling measures.

12.In most countries, induction of the code and related skills in the academic curriculum has helped a great deal in developing trained manpower. The channel can be established in Lebanon for rigorous training of professional through any of the operational regulatory / statutory bodies responsible for building approvals.

13.Some of the voluntary programs for high performance buildings are already present in Lebanon. The Lebanon Green Building Council (GBC) is an independent body and is working towards Lebanese applicable certification and labeling of buildings . This is in line with international best practices. However, some additional incentives can be floated through the TSBL or BEEC.

14.Demonstration projects would be required for TSBL to document the

122 | P a g e


design process including design discussions and decisions, together with the evaluation and approval process.

15.Mulitlevel numbering to be followed in the further development of standard.

16.Standard test procedures for determining the properties such as U-value of glass, insulation, etc. should be mentioned.

17.Trade-off method as give in TSBL 2005 can be adopted for further development. Tradeoff method should be part of prescriptive approach

18.Over-deck insulation may be recommended for cooling dominated zones, whereas under-deck placement of insulation is recommended for heating dominated zones.

19.The values for TSBL 2005 were arrived at much before the values of TSBL 2010. Also the payback analysis must have been done based on the cost of electricity and materials prevailing at these times. Further, both the codes are addressing only the thermal energy aspect of the building, the equipment efficiencies considered might not be same as the efficiencies that might be mandated in the proposed elemental code. Hence it is recommended that these values be revisited after the equipment efficiencies are included in the elemental code

20.In cooling dominated climatic zones, high albedo roof (cool roof) may be inserted as one requirement for building envelope.

21.Instead of giving the list of approved software, it might be better, to give the capabilities and requirements of the energy simulation software and any software meeting these requirements should be allowed to be used. Some names can be listed as examples.

22.It is recommended to continue the development of the tool developed for compliance for TSBL 2005 and include the proposed prescriptive requirements for lighting, HVAC etc

23.It is recommended to continue the development of the compliance forms developed for compliance for TSBL 2010 and include the proposed prescriptive requirements for lighting, HVAC, SWH etc
