BREEAM is the world’s foremost environmental assessment method and rating system for buildings, with 200,000 buildings with certified BREEAM assessment ratings and around a million registered for assessment since it was first launched in 1990.


BREEAM sets the standard for best practice in sustainable building design, construction and operation and has become one of the most comprehensive and widely recognized measures of a building’s environmental performance.

A BREEAM assessment uses recognized measures of performance, which are set against established benchmarks, to evaluate a building’s specification, design, construction and use. The measures used represent a broad range of categories and criteria from energy to ecology. They include aspects related to energy and water use, the internal environment (health and well-being), pollution, transport, materials, waste, ecology and management processes.
