Leadership in Energy & Environmental Design, is redefining the way we think about the 

The U.S. Green Building Council. 1993 

BREEAM is the world's foremost environmental assessment

places where we live, work and learn.

BREEAM is the world s foremost environmental assessmentmethod and rating system for buildings, with 250,000buildings with certified BREEAM assessment ratings andover a million registered for assessment since it was firstglaunched in 1990.

The German Sustainable Building Councilwas founded in 2007 by 16 initiators from various subjectareas within the construction and real‐estate sectors. Theaim was to promote sustainable and economically efficientbuilding even more strongly in future.
