Role of Building Products within BNB (German Assessment System for Sustainable Buildings)

Topics of Sustainable Building from the perspective of public administration

Development of sustainability assessment systems for other applications (eg, green campus)

Development of further methods, indicators, tools and databases

Development of instruments for exchange of experiences, public relations, etc.

Integration of the building sector into the national sustainability strategy

Formulation of objectives for international cooperation and international competition

Improvement of education and training

Improvement of the cooperation with associations of the building sector regarding the further development of sustainable building in Germany

The Guideline for Sustainable Building was implemented into the practical work of theFederal Building Authorities

The Assessment System Sustainable Building (BNB) has been successfully applied for federal buildings

Sustainable procurement is a fundamental principle of the of the Federal Government in Germany

The federal government will support the Federal States and municipalities in the implementation of sustainability assessment.

BNB - implementation of the national sustainability strategy.

Research Initiative “Future Building” of BMUB will promote further development of methods and tools for sustainability assessment.
