BNB – Assessment system for sustainable building

The Assessment System for Sustainable Building (BNB) is an instrument for planning and assessing sustainable building projects, particularly in the public sector. It supplements the Sustainable Building Guidelines of the Federal Ministry of Housing, Urban Development and Building (BMWSB) and offers a holistic assessment methodology for (federal) buildings and their surroundings. In a two-year collaboration between the Federal Ministry of Building and the DGNB, the first criteria catalog for the Sustainable Building Assessment System was developed based on the requirements of the guidelines.

The system is not only used for the final assessment, but also for quality assurance during the planning and construction phase. The sustainability criteria of the BNB should therefore already be used during project planning as orientation for the target agreement of a construction project. This ensures that the system requirements are also implemented during the construction phase.

Trained BNB sustainability coordinators provide advice and compile the documents required for the assessment.
