Evaluation

Precise adjustments. The weighting of criteria.

To make the DGNB certificate as informative and precise as possible, we have clearly defined target values for all criteria. Each criterion can receive a maximum of 10 points based on its documented or calculated quality. At the same time, it is possible to increase the weighting of each criterion as much as threefold or to disregard it entirely based on its societal or political relevance and its importance for the specific use profile.

Gold, silver, or bronze. Performance-based scoring.

The points granted by the auditor, planner, or architect for each individual criterion and the weighting of the criteria collectively produce the score for the overall building and the six topical categories. The score shows the extent to which the requirements are fulfilled. If the score is 50 percent, for instance, the building will receive a bronze certificate. The score can also be based on grades, with 3.0 being required for bronze. If the score is 65 percent, a silver certificate is granted. A gold certificate requires a score of 80 percent. The goal is to promote a standard of high quality for buildings. The performance in each of the topical categories relevant for the score therefore has to be of a certain minimum level for a certificate to be issued. For instance, gold requires a score of at least 65 percent in the first five topical categories. Silver requires a score of at least 50 percent; bronze, 35 percent.
