The Code for Sustainable HomesLes Fothergill Sustainable Buildings Division
Content of presentation • Overview of Code for Sustainable Homes • Discussion on proposed section on sound insulation • The content of the Code has not yet been finalised and so is subject to change
Background to the Code:Main Drivers • Climate change agenda and CO2 targets • Rising energy costs • Security of supply of energy • Water conservation • Signals future direction of Building Regulations
Background to climate change 1 • Climate change is already happening. • The ten hottest summers on record have occurred since the beginning of the 1990s • Models predict that global temperature could rise from between 1.4 to 5.8 degrees over the next 100 years
Implications for the UK • milder, wetter winters • drier, hotter summers • higher sea levels - leading to the flooding of coastal areas and floodplains
UK policy commitments • Kyoto Protocol of 1997: ratified by over 150 countries – set legally binding reduction targets of 5.2% below 1990 levels by 2008-2012 • The UK has set itself challenging targets to reduce carbon emissions by: • 20% below 1990 levels by 2010, and • 60% below 1990 levels by 2050 • Energy supply – to produce 12% UK electricity from renewable sources by 2010
Current trend of carbon emissions 2010 target = 129 mtC
Climate change and buildings • 46% of carbon emissions are from the use of buildings • 27% from dwellings
Rainfall Rainfall: Percentage of long term average – November 2004 - March 2006

Why a Code for Sustainable Homes? • Sustainable Buildings Task Group report recommended a single Code for England and Wales - with minimum standards for key resources: energy, water, waste, materials. • Fresh approach to achieve outcomes: • Encourage developers to offer more innovative solutions • Empower homebuyers.
Advantages of a Code • Advantages of a Code over Regulation: • Encourage aspirations above the regulatory base, in measured steps. • Point the way to future regulations and give certainty.
The consultation document 1 • Voluntary Code comprising essential and optional elements • A transparent rating system to inform home-buyers how sustainable the home they are buying is compared to another • Out to consultation (closed 6 March 2006) - over 2100 responses
Government has announced that all homes built with government funding (e.g. Housing Corporation, English Partnerships, etc) will meet Code Level 3 • As an interim measure – BRE EcoHomes “Very Good” from April 2006
Strengthening the Code 1 • ODPM (DCLG) Press Notice issued 9 March 2006 signalled proposals to “Strengthen The Code”; • Based on an initial analysis of consultation returns • Main options: • Make assessment to the code mandatory • Widen coverage of the Code • Encourage micro renewables • Use the Code to signal the future direction of Building Regulations
Strengthening the Code 2: Make assessment mandatory • All new homes and those sold or let will already have an • energy performance certificate • (a requirement of the Energy Performance of Buildings Directive); • Ministers are considering mandatory assessments against the whole Code - a sustainability rating.
Strengthening the Code 3: Widen coverage of Code • Ministers minded to extend the Code to cover existing homes, as well as new ones. • Perhaps to cover non-domestic buildings - new and existing.
Strengthening the Code 4: micro-renewables • Ministers wish to use the Code to promote on-site energy generation. • Homes that use micro-renewable technology will gain extra Code Points. • Details now being worked upon.
Strengthening the Code 5: Signal future direction of Building Regulations • Code should form the basis for the next wave of improvements to the Building Regulations. • It should indicate where the Building Regulations could be in 5, 10, 15 years time.
The Code - is it worth it? • Code base (in Consultation Document) saves up to 25,000 litres of water a year per house. Utility bill potential to save up to £800 per household. • Make homes less wasteful, more secure, and more comfortable. • As easy to understand as washing machine efficiency labels.
