BREEAM - A summary of changes to the 2011 version (Version 1)

TRADA image

The Building Research Establishment Energy Assessment Model (BREEAM) has dominated environmental assessment of UK buildings for nearly 20 years. BREAAM has become a leading environmental assessment method and rating system for buildings with 200,000 building certified using the assessment ratings and over a million registered for assessment.

A BREEAM assessment uses recognised 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.

This Construction Briefing explains the changes, which have been made since the 2008 edition of BREEAM and provides the reader with useful commentary on how the changes might affect them.

This sheet also gives a background to BREEAM and explains the process used to calculate a building's BREEAM rating, as well as the scores required to pass each of the benchmarks.
