One of the aimsof BREEAM is to encourage the use of materialsthat have lower impact on the environment,taking account of the full life cycle of thematerials in question.How does BREEAM work?BREEAM assesses the performance of buildingsin the following areas:• Management• Health and wellbeing• Transport• Ecology• Materials• Energy use• Pollution• Land use• Water52 Measuring environmental success
