Bree Day architects, as a pioneering member of Integer Intelligent and Green, has been working with its partners over many years to improve the environmental performance of its projects. 

The practice was deeply involved in the Millennium Demonstration House at the Building Research Establishment in Watford, which was the first stage of a programme to bring sustainable design to the mainstream.

There is no generic solution, each project needs to respond to the specific characteristics of programme, site and locaton.

Integer advanced the debate and knowledge of sustainability in construction, and had cross party support of MP's and local authorities.
