The DGNB aims to promote a uniform quality standard for buildings. Therefore the total score alone is not sufficient for a certificate.
A certain basic level – the minimum performance index – must be reached in all the result-relevant quality sections to be able to obtain the relevant certificate.
A score of at least 65 per cent in the first five quality sections is required for gold. A score of at least 50 per cent means silver and the building is awarded bronze for 35 per cent
