Transcript of Code for Sustainable Homes 11 th May 2010 Planning and Regeneration.
Code for Sustainable Homes
Introduction to the Seminar
Ruth Bamford Head of Planning and Regeneration
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%)
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
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
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
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 planPollution
• Avoiding GWP products • Reducing of NOx from
heating
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
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 standardsLevel 2 – • Energy and CO2 18% improvement over
Building Regulations
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
The Code - Levels
Level 4 - • Likely to be mandatory 2013 • Energy and CO2 44% improvement over
2006 Building RegulationsLevel 5 -• Energy and CO2 100% improvement over
2006 Building RegulationsLevel 6 –• Likely to be mandatory 2016• “Zero Carbon” • 33% improvement in water efficiency
