Code for Sustainable Homes

1. Code for Sustainable Homes 11th May 2010 Planning and Regeneration

2. Code for Sustainable Homes Introduction to the Seminar Ruth Bamford Head of Planning and Regeneration

3. A Brief Introduction to the Code Matthew Weatherill Building Control Surveyor

4. The Code – What is it? • Assessment of the environmental and social sustainability of new homes. • National standard covering 9 key areas: • Energy and CO2 emissions (36%) • Water use (9%) • Materials (7%) • Surface water run-off (2%) • Waste (6%) • Pollution (3%) • Health and well being (14%) • Management (10%) • Ecology (12%)

5. The Code – How is it Monitored? • Administered (enforced) through the planning (development control) process. • Certificates are required in HIPs • Produced By an Independently Accredited Code Assessor (Accredited By BREEAM or STROMA) • Paid for by the applicant/developer • Design Stage assessment • Post Construction Review including site visit and evidence gathering

6. The Code – Typical design Features Energy • High levels of insulation • Low air permeability • Low carbon heat sources such as ground/air source heat pumps and wood pellet boilers • Designs that reduce solar overheating • MVHR • Solar water heating • Photovoltaic cells • Energy saving appliances • Home office provision

7. The Code – Typical design Features Water Use • Rainwater harvesting • Greywater re-cycling • Water saving WC’s, washbasins, washing machines, dishwashers, showers, smaller baths! Materials • A-rated from BRE’s green guide • Responsibly sourced • Re-cycled

8. The Code – Typical design Features Surface water run-off • Rainwater harvesting • Attenuation systems • Soakaways (where feasible) • SUDS Waste • Space for recycling facilities • Composting facilities • Construction site waste management plan Pollution • Avoiding GWP products • Reducing of NOx from heating

9. The Code – Typical design Features Health and Wellbeing • Good natural lighting • Sound insulation • Private space • Accessibility and adaptability (lifetime homes) Management • Guidance for occupants • Security Ecology • Impact on bio-diversity • Improving ecology of site where possible

10. The Code - Levels Level 0 – • Nil Rated Certificate for HIPs • Mandatory April 2008 • Energy and CO2 as Building Regulations part L 2006 standards Level 1 – • Energy and CO2 10% improvement over Building Regulations • Water usage equal to part G 2010 standards Level 2 – • Energy and CO2 18% improvement over Building Regulations

11. The Code - Levels Level 3 – • Likely to be mandatory October 2010 • Many planning departments already asking for this level including Redditch BC • Energy and CO2 25% improvement over 2006 Building Regulations; equal to 2010 part L standard? • Water usage 12% less than part G 2010 standards

12. The Code - Levels Level 4 - • Likely to be mandatory 2013 • Energy and CO2 44% improvement over 2006 Building Regulations Level 5 - • Energy and CO2 100% improvement over 2006 Building Regulations Level 6 – • Likely to be mandatory 2016 • “Zero Carbon” • 33% improvement in water efficiency
