BREEAM (Building Research Establishment Environmental Assessment Method) is a leading sustainability assessment method for buildings. BREEAM is used worldwide and helps developers, building owners, and occupants to measure and reduce the environmental impact of their buildings.

BREEAM provides ratings based on a building’s environmental performance, ranging from “Pass” to “Outstanding”. BREEAM “Outstanding” buildings are those that have achieved the highest rating possible in the assessment. So, what makes a building “Outstanding” according to BREEAM? Firstly, a building  must achieve a score of at least 85% across nine categories: Management,  Health and Wellbeing, Energy, Transport, Water, Materials, Waste, Land Use and Ecology, and Pollution.

In addition to achieving high scores across these categories, “Outstanding” buildings must also meet strict requirements for energy performance, including achieving net-zero carbon emissions from regulated energy, and incorporating renewable energy sources on-site or off-site. Furthermore, “Outstanding” buildings must prioritize the health and wellbeing of their occupants, through measures such as providing access to natural light, fresh air, and green spaces, as well as promoting physical activity and healthy food options.

Finally, “Outstanding” buildings must also demonstrate a commitment to sustainable materials and waste reduction, using materials that are responsibly sourced, and minimizing waste throughout the construction and operation of the building.

Achieving a BREEAM “Outstanding” rating is no easy feat, but the benefits are significant. “Outstanding” buildings are recognized for their leadership in sustainability, and are more attractive to tenants, investors, and other stakeholders who prioritize sustainable development. In conclusion, BREEAM “Outstanding” buildings are leading examples of sustainable construction, and demonstrate the potential for buildings to have a positive impact on the environment and the health and wellbeing of their occupants.
