BREEAM – Building Sustainability Rating System

BREEAM (Building Research Establishment Environmental Assessment Method) sets the standard for best practice in sustainable building design, construction, and operation and has become one of the most comprehensive and widely recognised measures of a building’s environmental performance.

Green Building Certification

The increasing demand for sustainability, in relation to products and processes, is leading to rapid changes in policies, laws, and regulations around the world, to encourage more sustainable projects.

A number of rating systems, therefore, exist to assess the environmental impacts of buildings, constructions, infrastructure, urban-scale projects, and community projects.

BREEAM is a Green Building Certification that is designed to assist projects to be more sustainable by providing frameworks with a set of criteria that cover several aspects of a project’s environmental impact.

Our Team Can Help You Achieve Green Building Status for Your Building


Many clients want to protect their building assets and do so by embarking on a formal sustainability or health and well-being rating system. This can attract higher rent yields, and market demand and ultimately add more value than non-related equivalents.

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 assess areas related to management processes, health and well-being, energy, transport, water, waste, land use, and ecology and pollution.

There are five possible ratings that can be achieved:

  1. Pass
  2. Good
  3. Very Good
  4. Excellent
  5. Outstanding

If you would like to know more about BREEAM and whether it is the right rating system to assess how green your building project is please get in touch with one of the team today – we have a dedicated BREEAM Accredited Professional and a BREEAM Assessor in-house.
