Internationally Recognized Systems for Building Sustainability
BREEAM
The “Environmental Assessment Method” (EAM) for buildings was originally developed by the “Building Research Establishment” (BRE), a British research institute, under the name BREEAM. BRE has certified and operates more than 100,000 buildings in 15 countries outside Great Britain. This makes BREEAM the world's leading and most widely applied certification method for buildings.
DGNB
“German Society for Sustainable Building” (DGNB): The task of this organization is to develop and promote ways and solutions for the sustainable planning, construction and use of buildings. The DGNB evaluates quality over the complete life cycle of the building. When the specified criteria are fulfilled through the standard, DGNB awards bronze, silver and gold level certificates. DGNB also offers advance certification during the planning phase.
LEED
“Leadership in Energy and Environmental Design” (LEED) is a classification system for ecological construction developed by the “U.S. Green Building Council.” The aim of this certification standard is to define a high-quality, ecological method of construction for healthier, more environmentally friendly and more profitable buildings. Buildings are evaluated by awarding points for individual criteria. The sum of points awarded determines how the building is classified for certification.
