BREEAM (Building Research Establishment Environmental Assessment Method) is a leading and internationally recognized sustainability assessment method for evaluating the environmental performance of buildings. Developed in the United Kingdom in 1990 by the Building Research Establishment (BRE), BREEAM provides a comprehensive framework for assessing, rating, and certifying the sustainability of buildings across various categories. These categories include energy usage, water efficiency, materials selection, waste management, indoor environmental quality, and innovation in design.

The BREEAM assessment was designed to help reduce the negative environmental impact of buildings by promoting sustainable practices and encouraging the construction of environmentally responsible buildings. It offers a clear and measurable way to assess a building's environmental impact and sustainability performance throughout its lifecycle, from design to construction and operation.

Since its inception, BREEAM has grown from a UK-based certification system into an internationally recognized standard. Today, BREEAM assessments are applied to buildings and developments around the world, making it one of the most popular environmental rating systems globally.
