It Started With BREEAM When BRE introduced BREEAM in 1990, it quickly became the industry standard for sustainable building design and construction.

BES 6001 Takes Sustainable Design to the Next Level BRE’s BES 6001 was introduced in 2012 as the environmental standard for the responsible sourcing of construction products. It is one of the nine key criteria used to evaluate sustainable design within the BREEAM assessment process, see figure 1.
