Housing: Carbon Emissions

Volume 464: debated on Tuesday 16 October 2007

To ask the Secretary of State for Communities and Local Government how many tonnes of carbon are emitted each year by an average home built in accordance with (a) current building regulations and (b) the level three energy/carbon standard of the Code for Sustainable Homes. (157403)

If an average home is assumed to be a semi-detached house with a gas-fired boiler and a floor area of 88.8 metres squared, then the carbon emissions associated with space and hot water heating, ventilation and fixed lighting (not appliances) is estimated to be:

(a) 0.553 tonnes of carbon per annum for a home build to Part L of the current Building Regulations (2006);

(b) 0.415 tonnes of carbon per annum for a Code level 3 home.

The energy/carbon standards set for Code level 3 homes represents a 25 per cent. improvement on current building regulations and will become the minimum regulatory standard for new homes when Part L of the Building Regulations are revised in 2010.
