What is BREEAM?

Founded in 1990, BREEAM was the world’s first sustainability assessment method for buildings and is the most used rating system worldwide. BREEAM In-Use was developed in 2009 and is the BREEAM program for existing commercial buildings. BREEAM In-Use is a methodology backed by scientific research to rate buildings based on performance benchmarks. There are no prerequisites or other barriers to participation that can make a sustainability program costly and time consuming.
