As a leader in the drive for a sustainable built environment since its launch in 1990, BREEAM has contributed much to the strong focus on sustainability in building design, construction and use that now exists in the UK. This publication presents a real picture of BREEAM take-up, from humble beginnings founded on principles that still hold today, to an internationally recognised and applied methodology. The data presented and trends highlighted should be viewed as more than just numbers on the market penetration of BREEAM. They are an increasingly valuable bank of knowledge that reflects the degree to which the buildings we design, construct, operate and occupy are sustainable and therefore lower risk, higher value assets.
