Drivers

EISA 2007

California Zero Net Energy Action Plan

Outcome-based Codes

Presenter
Presentation Notes
Code Progress - Outcome-based Codes, Performance Approach for Building Energy Use Energy Independence & Security Act All New commercial buildings by 2030; Fifty percent of all commercial building stock by 2040; and All commercial buildings by 2050. All new commercial construction in California will be zero net energy by 2030 and 50% of existing buildings 2030 Challenge as the full support of the 80,000 AIA members, the Council of Mayors, and literally hundreds of organizations and Leading Firms CBC – represents leaders forming the recommendations and technical approaches on behalf of DOE to create the pathway to the low-energy future needed to address the major carbon and climate issues of our time. Market uptake of EnergyStar, LEED, USGBC and the Living Building Challenge through the Int. Living Future Institute and Cascadia GB Council is dramatic. It is really a watershed time of moving to buildings that reflect this millenium’s abilities and interests in improved technology and designs – and occupant comfort – in the built environment. The amount of energy provided by on-site renewable energy sources is equal to the amount of energy used by the building. · A ZNE building may also consider embodied energy – the quantity of energy required to manufacture and supply to the point of use, the materials utilized for its building.

Ratings & Labels

Presenter
Presentation Notes
One of the most important market and regulator trends is the increase in ratings and labeling. Driven first by green building labels such as LEED and Energy Star, but followed now by disclosure ordinances that are adopted or pending in over a dozen localities. Energy Star Score ASHRAE Building EQ (Energy Quotient) Label – pilot underway – Durst, BNIM zEPI (based on Charles Eley’s Beyond Percent Savings) New CA Building Energy Asset Rating System (BEARS) Also mention the 2030 Challenge Another area where policies and requirements help move design practices is with labeling of buildings. The two powerhouse labels in the market are LEED and Energy Star but I want to mention that there are several trends that go further to influence actual energy performance. This is the inclusion of an as-designed label and an as-operated label in the regulatory and the market vernacular. Energy Star is an operational label and USGBC added a requirement for post-occupancy energy information to their new construction program and requires a Energy Star rating for their existing building program. CA is developing BEARS and there is a wide recognition that we have to move “beyond percent savings” to a scale aligned with Net Zero Energy policies. All of these provide the design team both opportunity and accountability.

Presentation Notes
For Example – map from International Inst. For MT These Disclousre requirements rely primarily on whole building annual energy data and in most cases the representation of that data through the Energy Star Portfolio Manager benchmarking tool. In a recent meeting with a group of A&E firms they identified this trend as being one of the largest shifts in attention to energy use by their clients they have seen – thus it is facilitating their proposals to go deeper in the recommended energy improvements.

Plug Loads Now becoming 30-60% of high performance buildings energy use

Presenter
Presentation Notes
NBI and ECOS recently completed research through the CA PIER program that showed a potential to reduce the office equipment energy use through low-to-no cost improvements to existing equipment by 15-40%, much more at the time of replacement. You CAN’T address deep energy savings without approaching the behavorial and power mgmt. Aspects of Plug Loads.

RMI Deep Retrofit Needs Assessment1. Financing: none available

2. Risk/litigation: never done it before; don’t want to reduce installed cooling capacity, don’t want to force on tenants, etc.

3. Business case: rapid building turnover; more compelling alternative investments, etc. Value of energy efficiency

4. First cost: cost of technologies and of services, etc.

5. Split incentives: tenant/landlord; costs of sub-metering, etc.

6. Retrofit process: time-consuming phases; non-standardized analysis/audit procedures; difficult to engage all stakeholders

7. Design: few capable engineers; cream-skimming habits; no incentives to maximize savings, etc.

8. Awareness and demand: uncertain tenant demand for energy efficiency, etc.

What about data?

• ~ 5 million commercial buildings nationwide

• 100,000 using Energy Star Portfolio Manager

• 10,000 Energy Star Labeled, 10,000 LEED buildings, DOE’s High Performance Database, Better Bricks Database, AIA COTE Awards , NBI’s GT50 data, utility programs – est. 25,000 +/-

100 thousand using Portfolio Manager

25 thousand E.S./LEED labeled etc. High Performance Buildings

Presenter
Presentation Notes
High attention and involvement in Estar represents 100,000 buildings and hundreds of the national leading CRE firms and owners. If you round up all the green and energy efficiency programs – to the extent that data is attainable – you might have 25,000 buildings This represents ~<0.5% of commercial buildings with publicly available measured performance data With EPA it is still less than 5% of commercial buildings. Let’s say that, like the qty versus sf slide, these represent big bldgs (which they do on average) and that the sf to size ratio is 10 fold (5% of the bldgs are >50k sf but they represent half the sf) so by sf there “Might be” Up to 30-50% of commercial sf is active in high performance, especially due to the leading CRE firms involved in Estar Certification

Presentation Notes
In order to measure change or progress (change may not always be toward progress) you have to measure against something else. Let’s get some common vocabulary for today’s webinar. Measuring. CBECS – can’t track progress, not that we can’t MAKE progress. Market is most interested in pre and post Typical commercial buildings use, on average, twice the energy of efficient buildings and three to four times that of the nation’s highest performing buildings.

Presentation Notes
Design teams could begin to have a portfolio of performance information. Substantive complexities in the interpretation of the reasons for variations in performance – but the most common, after normalizing for building type and climate, being occupancy density and duration, equipment selection. The psychology of comparative tendency is very powerful and people want know where is my building on this line.

– Real Estate Industry is Repositioning Assets

– Improving existing buildings is the best value now

– Where deepest savings are more likely to occur

– More public and ‘green firms’ continuing to renovate buildings during the economic downturn

– Larger scopes are more likely to be documented

– Single measure or ‘shallow’ retrofits are less likely to be found in a search (more contractor driven)

Why did we find mostly “Renewals”** “renewals”, “major renovations”, “whole building upgrades” all denote that the building had significant changes to the interior, structure and/or activity type in addition to efficiency measure improvements.

• Best of Best – advanced mechanical, daylighting, advanced controls, natural ventilation plus pay attention

• Worst of Best – usually no clue that building not performing, mostly operational issues, occasionally design or construction; Cx post occupancy should fix most

• Ongoing measured performance of buildings is critical– Metering and monitoring

Digging into buildings and data

Cross-Cutting Themes

• Integrated design is more critical to the development of low/zero-energy buildings than is any given technology.

• Moving beyond design and construction into operations, plug loads, process energy and other “unregulated loads” is a critical step.

• There is need for a consistent, long-term metric to measure the performance of buildings and policy, such as the Zero Energy Performance Index (zEPI).

• More measured performance data at the case-study level, and at the system level to support owner and private financing.

Presenter
Presentation Notes
Codes and performance assurance initiatives (O&M and energy management) can get into building operations phase and unregulated loads. This is increasingly important as plug loads’ share of building energy use grows over the years and envelope, HVAC, and lighting are minimized and stabilized. zEPI – metric where 100= avg EUI in year 2000 and 0 = zero Measured performance data echoes needs voiced by technology WGs

Deep Savings Webinar 6/30/2011

What about zero-net energy buildings?• About 20+ built in U.S.

• Documenting net zero capable (i.e. less than 30 kBTUs site)

• Except for NREL, mostly small

• All the basics plus very efficient HVAC, daylighting, natural ventilation, heat recovery and design

• 50+ projects under design/ construction, e.g. Living Building Challenge, Savings by Design, Energy Trust of Oregon

NBI study – to be released soon

How to move existing buildings

• Create and support innovative technical solution sets that build on the strengths of existing buildings.

• Critical need for new financial tools that can support deep savings (40% to 60%)

• Move from widget based efforts to integrated system based efforts with enhanced controls.

• Provide like examples of projects.
