Evaluation and awards

The DGNB has defined target values for each criterion. Up to 10 evaluation points are awarded for reaching the target specifications. Depending on the scheme, some criteria are weighted differently.

The concrete score for the six topics is calculated from the combination of the evaluation points with the relevant weighting. The total score for the overall project is calculated from the five quality sections based on their weighting. Site quality is considered separately and this aspect of the building is included in the commercial viability criterion. With urban districts, on the other hand, the site quality is included in all criteria.

The DGNB’s Awarding system

The DGNB has changed its awarding system for buildings and urban districts. Since 1 of July 2015, Platinum is the highest award that can be achieved under DGNB certification. The evaluation criteria as well as the assessment methodology  remain unchanged; only the colours representing the level awarded, based on the total performance index, have been modified. The new rating system from highest to lowest is:

  • Platinum is awarded to projects that achieve the same conditions of projects previously awarded with a gold certificate.
  • Gold is awarded to projects that meet a performance index previously certified in silver, and subsequently. 
  • Silver is now awarded to projects achieving the requirements previously awarded with bronze.
  • The bronze certificate is no longer used for awarding new buildings.
  • Bronze certificates are only possible for existing buildings and replace the lowest DGNB award, “Certified”. Otherwise, the awarding system for new buildings shall apply.


The DGNB System evaluates according to performance indices

If the total performance index is at least 50 %, the building will receive a DGNB Certificate in silver. If the total performance index is at least 65 %, a DGNB Certificate in gold is granted. To achieve a DGNB Certificate in platinum, the project has to achieve a total performance index of at least 80 %. For existing buildings, the same system applies with the addition that bronze is conferred as the lowest award with a total performance index of at least 35 %.


The DGNB aims to promote a uniform quality standard for buildings. Therefore the total performance index alone is not decisive in achieving a specific certificate. Rather, the result-relevant topics must each achieve a minimum performance index in order to be able to obtain the certificate. To achieve platinum, for example, a minimum performance index of at least 65 % must be achieved in the first five quality sections. A minimum performance index of at least 50 % is necessary in order to achieve a gold certificate. For silver, a minimum of 35 % must be achieved for each area being tested. When awarding existing buildings, there is no minimum performance index for the lowest award level, bronze.


Adaption of previously certified projects to the new DGNB Awarding System

The new DGNB awarding system applies to all projects registered for certification since 1 July 2015. All projects certified according to the previous system can be adjusted to fir the new ratings. This update shall be done on voluntary basis and only if expressively requested in written form to the DGNB.

Previously certified projects will be adjusted with no further evaluations or additional costs. The new award plaque and certificate will be replaced at cost price.
