“Sustainability is meeting the needs of the current generation without impacting the ability of future generations to meet their own needs”

40% of the energy consumed in the UK is used in the construction and use of buildings. The average 4 bedroom home contains around 200 tonnes of materials, some 84% of which are virgin (never before used). Some 12% of those virgin materials will go straight to landfill without ever being used.

The Welsh Assembly Government has given the home building industry until 2011 to deliver zero carbon houses.
