Miljöbyggnad (MB) consists of two major schemes: one for new construction, and one for existing buildings. Projects that meet the requirements can be awarded certificates at three levels: Gold, Silver, or Bronze. Since the standards of the MB system are based on the Swedish Building Regulations, which govern the entire country, it is applicable to all building projects in Sweden since 2011.
There are only 15 indicators measured for certification, all of which pertain directly to the building itself. The criteria can be clustered into three different categories: Energy, Materials, and Indoor Environmental Quality. During the procedure of Miljöbyggnad certifying, credits given by indoor environment performance is around 60% of the total credits which represents the main portion of building energy and environmental performance.
