Green Building with BREEAM How BREEAM works BREEAM rewards performance above regulation which delivers environmental, higher comfort or health benefits. BREEAM awards points or ‘credits’ and groups the environ- mental impacts into the various sections. The total number of points or credits gained in each section is multiplied by an environmental weighting factor which takes into ac- count the relative importance of each section. Section scores are then added together to produce a single overall score.
