BREEAM (and the Code for Sustainable Homes) is the most widely used environmental assessment method for buildings in the world and continues to drive higher standards of sustainability in the built environment. This BRE Trust Report provides practical information on how to achieve higher BREEAM and Code for Sustainable Homes ratings and improve the sustainability of assessed buildings. It will help all parties involved in a building's construction to streamline and integrate the environmental assessment process into day-to-day design practice. The tools on the accompanying CD-ROM are customisable, visual tables that facilitate the integration of BREEAM and the Code for Sustainable Homes within the design process, issue by issue.
