How can good quality carbon
reduction schemes be achieved
through the planning process?
Steve Charter
Training Development Manager
Green Gauge Trust
Can you achieve good quality sustainability / carbon reduction in planning in a viable way?
However, this depends on having a good understanding of what is:
� good quality
� viable e.g. in cost and buildability
in terms of both:
� sustainability/carbon reduction
� planning policy and practice
Yes
There’s 26 million existing homes to deal with now.
Responsible for 27% of current UK carbon emissions …
Why buildings are important: 45% CO2 emissions
All new homes ‘zero carbon’ by 2016;
All new commercial & public buildings ‘zero carbon’
by 2019
Domestic CO2 emissions to be reduced by 26% by
2020, and by 80% by 2050
80% of homes in 2050 have already been built
Planning System
Purpose of the planning system:
• To deliver sustainable development
• To encourage ‘good design’ and prevent ‘poor
design’
• To complement other regulatory and policy
approaches
Plus:
• To help mitigate and adapt to climate change
PPS1, Design - paragraph 35
Para 35:• High quality and inclusive design .... means ensuring a place will
function well and add to the overall character and quality of the area, not just for the short term but over the lifetime of the development. This requires carefully planned, high quality buildings and spaces that support the efficient use of resources.
Good design should:– address the connections between people and places by considering the needs of people to access jobs and key services;
– be integrated into the existing urban form and the natural and built environments;
– be an integral part of the processes for ensuring successful, safe and inclusive villages, towns and cities;
– create an environment where everyone can access and benefit from the full range of opportunities available to members of society; and,
– consider the direct and indirect impacts on the natural environment.
PPS1, Design - paragraph 36
• Planning authorities should prepare robust
policies on design and access... Key objectives
should include ensuring that developments:
– are sustainable, durable and adaptable
(including taking account of natural hazards
such as flooding) and make efficient and
prudent use of resources;
PPS1, Design - paragraph 38
Para 38
Design policies should avoid unnecessary prescription or detail and should concentrate on guiding the overall scale, density, massing, height, landscape, layout and access of new development in relation to neighbouring buildings and the local area more generally.
Local planning authorities should not attempt to impose architectural styles or particular tastes and they should not stifle innovation, originality or initiative through unsubstantiated requirements to conform to certain development forms or styles.
It is, however, proper to seek to promote or reinforce local distinctiveness particularly where this is supported by clear plan policies or supplementary planning documents on design.
PPS1: Climate Change Supplement
• Tackling climate change is a key Government priority for the planning system.
KEY PLANNING OBJECTIVES
9. To deliver sustainable development ... all planning authorities should prepare, and manage the delivery of, spatial strategies that:
• in providing for the homes, jobs, services and infrastructure needed by communities, and in renewing and shaping the places where they live and work, secure the highest viable resource and energy efficiency and reduction in emissions;
• secure new development and shape places that minimise vulnerability, and provide resilience, to climate change; ...
• conserve and enhance biodiversity ...;
• respond to the concerns of business and encourage competitiveness and technological innovation in mitigating and adapting to climate change.
PPS1: Climate Change Supplement
10. Regional planning bodies and all planning authorities should apply the following principles in making decisions about their spatial strategies:
• the proposed provision for new development, its spatial distribution, location and design should be planned to limit carbon dioxide emissions;
• new development should be planned to make good use of opportunities for decentralised and renewable or low carbon energy;
• new development should be planned to minimise future vulnerability in a changing climate;
• climate change considerations should be integrated into all spatial planning concerns;
PPS1: Climate Change Supplement
31. There will be situations where it could be appropriate for planning authorities to anticipate levels of building sustainability in advance of those set out nationally. When proposing any local requirements for sustainable buildings planning authorities must be able to demonstrate clearly the local circumstances that warrant and allow this.
32. When proposing any local requirement for sustainable buildings planning authorities should:
• focus on development area or site-specific opportunities;
• specify the requirement in terms of achievement of nationally described sustainable buildings standards, for example in the case of housing by expecting identified housing proposals to be delivered at a specific level of the Code for Sustainable Homes;

What is Good Design:
‘Good design’ now clearly relates to:• Location
• Layout (including orientation)
• Landscape
• Appearance
• Functional DESIGN i.e. performance of any development and buildings in energy and carbon terms

Defining Sustainable Building
The terms ‘sustainable building’, or ‘sustainable
construction’ should be:
a) Defined in a meaningful way in practical terms
b) Consistent & clear
c) Based in environmental, social & economic realities
In your experience, are they?
Defining Sustainable Building
• Not a single definition
• or an ‘A + B + C = D’ definition
In essence, it’s about:
a) Design + Construction + Use + Demolition /Re-Use
b) Significantly Reducing ‘Whole Life’ Negative Impacts
c) Consciously Increasing ‘Whole Life’ Benefits
• i.e. Sust Building = Whole-life x minimised negative
impacts x maximised positive benefits
The Environmental Baseline
Fundamental environmental baseline for development
/ building to become ’sustainable’:
To stabilise climate change:
– 80%+ reduction in CO2 / GHG emissions
For sustainable resource use:
– 65-75%+ reduction in impacts / improvements in resource efficiency (i.e. based on ecological footprint & lifecycle impacts);
– shifts to circular resource cycles.
(These are not up for debate here ... I won’t tell you how to lay bricks, if you don’t tell me what’s sustainable ...)
Core Environmental Components for
Sustainable Building
• Energy and Carbon / climate impacts;
• Waste & Resource Efficiency;
• Water;
• Health & Pollution;
• Ecology & biodiversity;
• To transform the quantity of impacts
• To transform the quality of impacts
Source: PHI Darmstadt / AECB
2. Max Thermal Efficiency
/ Min Heat-loss
• Super insulation: walls, floors, roof
• Airtightness & MVHR/heat-recovery
• Minimum thermal bridging
• Buffer-zones / sun-spaces
• High performance windows & doors
4. Minimising Energy
& Electrical Demand
• natural lighting
• e.g. LED lighting
• AA* appliances
1. Max Solar Gain &
Min Over-Heating
• Location &
orientation
• Summer shading
• Low-e glass
5. Minimising Water
Demand & Runoff
• low flush toilets
• efficient showers,
taps, appliances, etc
• rainwater harvesting
• greenroof, SDS, etc
3. Natural / Low Impact
Products & Materials
• structural & insulation
• internal & external
finishes
• local-regional supplies
4. Waste
Minimisation
• materials selection,
not over-specifying
• re-used / recycled
materials
• site waste minimis-
ation plan
6. Enhancing Ecology
& Biodiversity
• site works
• landscaping
• within structure e.g.
greenroof, built-in bat
boxes, etc
Need: Skills for doing
these things well ...
Other Key Components & Considerations
• Buildability and Usability / Simplicity : not a fiddley and complicated building envelope; not dependent on complex technologies which users don’t understand or use properly; no-one local to maintain or repair, etc.
• Future proofed: adaptable, re-usable building / components, etc.– adaptation to & mitigation of climate change i.e. to prevent over-heating
Economic & Social Components:
• Local-regional supply and local employment & training : supply chains; local multiplier effects; training & skills; SROI (Social Return on Investment);
• Affordability: emphasis depends on sector
– affordability in construction + affordability in running costs (very important social housing driver) + affordability in in R&M costs (very important social housing driver)
– maintaining value.
• Balance between Economic Efficiency & Commercial Efficiency: often presented as the same thing, but they are not.

Sustainable Building Standards
Low Energy Building Standards
• Passivhaus (Germany; Austria)
• Minergie (Switzerland)
• Super-E (Canada)
• Part L (UK)
Mainstream Sustainable Building Standards
• GreenStar (Australia)
• LEED (USA)
• Code for Sustainable Homes (UK)
• Code for Sustainable Buildings – (UK, impending)
• BREEAM (UK)
Marginal Standards
• AECB Gold & Silver Standards (UK)
Trend: UK v's Global Perspective
UK Focus: on BREEAM, CSH and SAP
Global Focus: now on kWh/m2
Revised Definition of ‘Zero Carbon’
Recommended Fabric Efficiency Standards
• Recommended Metric = kWh/m2/yr– 39 kWh/m2/yr: flats & mid-terrace;
– 46 kWh/m2/yr: semis / end-of-terrace & detached;
• Covering Space heating & cooling energy demand
• Passivhaus as a global benchmark:• Based on building physics; 20 years of experience;
• Methodology based on accurate predictions of performance – not on notional buildings (SAP);
Green Deal and Housing Retrofit:
volume / market
To achieve an 80% reduction by 2050
• 600,000+ housing retrofits per year (UK) =
– 2,500 retrofits/working day; 333/working hour; 5.5 a minute!
• SE region = 45 retrofits / working hr = £1mn / wking hr
• Radian housing stock = 400 homes / year = £8mn / yr
• = 1.5 / working day = £320,000,000 by 2050 at current costs.
South East Skills Needs = (80,000 / 4.5) x 12 =
213,000 Permanent SE retrofit trade workforce?! Plus 6,600+ professional/technical workforce?
• Figures based on conservative estimates from experience of low carbon refurbishment projects, figures developed with Paul Ciniglio, Sustainability Manager, Radian Housing
Example: Whole Life Carbon ProfileTypical commercial building
Building Related Carbon Emissions
Scale of Issue:
� large sector (1.2million people+ construction; 2million incl. buildings/property/housing), many organisations & roles, complex, huge number of subbies & small builders;
� Existing homes: 26 million to low-to-zero carbon;
Knowledge:
� of energy and buildings in the UK is very poor;
� distorted knowledge:
� a) has been new build focused, ahead of existing stock;
� b) focused on Codes, etc not buildings & performance.
Skills:
� (virtually) no body has a complete picture;
� trade based, not outcome-based, team or multi-skill based;
� No comprehensive, coherent qualifications and courses
� Very (very) few competent trainers
UK: Known Problems or Opportunities
Levels of Knowledge & Risk
General Risk and Planning Associated Risk associated with Low Energy Sustainable Building outcomes:
1. Client: 85% of knowledge of key issues for tender and design brief
e.g. Limited knowledge means 90% chance of success in desired outcomes
1. Designer / design consultant: 85% of knowledge of key design issues
2. Project Management: 85% of knowledge of key project management issues
3. Site Management: 85% of knowledge of key site management issues
4. Site Skills: 85% of knowledge of key installation and construction issues
5. Risk Is Cumulative i.e. 0.85 x 0.85 x 0.85 x 0.85 x 0.85 = 0.4437
i.e. Less than 50% chance of achieving desired outcome (this is probably optimistic!)
Where Are We Now?
Risk and Opportunity
7 Factors re the Risk / Opportunity associated with carbon reduction and sustainable building issues are:
1. Becoming very visible: tender requirements; exemplar buildings, good practice, tighter regulations / energy standards, etc
2. Bringing about system change: a little like the Housing Act, or the Egan Review
3. Becoming very current: PPS1 Supplement, new Part L, CSH Level 3 or 4 requirements, Green Deal, etc.
4. Getting simpler: e.g. kWhr/m2 targets; simply a response to regulations and legislation (Part L; CRC; etc) and the market; clearer definitions and targets;
5. Creating a response from the whole sector +govt +individuals
6. Creating clear career and company opportunities and threats: e.g. the threat of not securing enough business because of not being on tender lists /not being able to demonstrate competence
7. Being responded to in matter-of-fact ways in the sector
Predictable Trends: 2010-2015
The best will become clear and be known:
1.Standards, Certification and Competency schemes
2.Building design and construction methodologies
3.Product + Technology combinations
4. TRAINING
It will be good planning to know in advance how to:
a) achieve standards locally;
b) encourage and plan for the above.
Predictable Changes: by 2015
• Anyone learning about or working in planning and built environment sectors now and in the future will be working in a world where:
– Low energy sustainable buildings are the norm
– sustainable building products & energy technologies are either commonplace, the norm or a legislated requirement
• Definitions will be clear & widely understood i.e.
‘Sustainable’ =
(low energy, low carbon) x (use + construction + end-of-life) = whole-of-life
+ waste min + water efficient
+ healthy (physiological, environmental, social and economic)
cool in summer
= sustainable
Very low running
costs
warm in winter
excellent indoor air quality
A shift in understanding, like going from a privy to a house with indoor plumbing!
It will become know and understood that
well designed, well built
low energy low carbon buildings =
The Future
� Buildings built and refurbished to absolute
energy targets
� Delivered by teams with skills accreditation
Assurance of:
a)design and build quality
b)energy performance outcomes
The Emerging Present & Future:
Summary of Planning Implications
1. Trends in: a) LC Building Policy, Regulations and Standards, and
b) Market & Contract Conditions (e.g. precedents)
These trends imply changes in:
a) what are appropriate planning conditions
2. Implications for Knowledge, Skills & Competence in terms of what constitutes Good Design and how planning can support its delivery
3. Needs for proof of performance at both application and project completion stages in:
a) high building energy performance standards
b) low / zero waste, sustainable procurement, etc

Sustainable Buildings Skills
We can create low energy sustainable buildings in cost effective, efficient and reliable ways whenwe have the skills and knowledge to do so.
• This is so for existing buildings or new build
IMPORTANT - mainly this involves:
a)improving or refining existing skills
b)adding new knowledge.
Planning Skills for Low Carbon Development &
Sustainable Buildings
• In a practical sense, planning skills for low carbon development and sustainable buildings are:
Planning skills & knowledge which:
a) Enable the key components of low carbon development & sustainable buildings to be achieved,
b) In ways that are cost effective, efficient & reliable.
� Skills relating to proper implementation of low carbon development and sustainable building and design methods:
� 5 core components + process skills
Defining Sustainable Building Skills

Other Key Skills: Ecology & Health
• Skills for enhancing ecology and biodiversityEssential for a sustainable built environment – but not essential for all– usually supplied by landscape designers & ecologists. However: basic awareness will be useful.
• Skills for Healthy Buildings
For some clients this will be very important –increasingly recognised as creating higher employee productivity and lower absenteeism costs.
Other Important Skills: various
1. Whole-Life and Costing Skills:– Understanding the whole process – the big picture and the detail
– Adding, subtracting and multiplication - selecting and weighing-up the right coefficients, factors and variables
2. People Skills:– Team / communication skills
– Client e.g. if refurb happens with residents in occupation.
3. Modelling Skills: a) Excel e.g. for PHPP, b) 3D modelling, c) THERM (thermal bridging), d) etc
4. Energy Monitoring & Efficient ICT Systems– Intelligent energy / building monitoring and management systems
– Green ICT – because ICT is a large energy user & secondary heat producer in commercial and public sector.
5. Business development & commercialisation skills: specialist sales, finance & marketing, etc
Training Problems / Challenges
Currently a distinct lack of:
1.Formally accredited courses on sustainable building issues;
2.Low-energy building content within mainstream building-related qualifications e.g. BTECs, NVQs, etc.
3.Trainers with real experience / competence in low energy sustainable building.
Skills Development Planning Process
Problem / Challenge:
Insufficient SB knowledge / skills
Solution:
plentiful SB knowledge / skills
Strategy :
develop & action SB knowledge / skills plan
Sustainable Building Skills Plan
Recommendation:
Develop a Skills Plan / Learning pathway for low energy sustainable building skills & competence
Including getting to know:
a) training which is available now in key skills areas;
b)training which is known to be in development;
c) key organisations involved in providing, brokering & developing sustainable building training e.g. SusCon, AECB Carbonlite, Green Gauge, etc;
Skills Plan Objectives
1. Identify / establish training priorities and progression
routes for staff learning / career development
2. Define your learning system, involving both formal and
informal education
3. Undertake a process of training to fill knowledge/skills gaps.
4. Develop a shared language and understanding
a) In your company
b) With you supply chains / project partners
c) With your clients
