This Information Paper is intended for housing professionals interested in the challenge of delivering housing to zero carbon standards. The Barratt Green House, winner of the 2007 Home for the Future competition, and built on the BRE Innovation Park, uses innovative concrete products to achieve this aspiration with the design and construction involving the application of concrete products in the building fabric. This publication discusses how zero CO2 emissions were achieved through the adoption of low carbon and renewable energy technologies. Finally, the Paper also brings together key conclusions and the wider lessons learned.
