DGNB Certification: Global Benchmark for Sustainability

As a planning and optimisation tool for assessing sustainable buildings and districts, the DGNB System helps to increase real sustainability in construction projects. It is based on a holistic understanding of sustainability that takes into account the environment, people and economic efficiency in equal measure. There are separate variants of the DGNB System for new buildings, refurbishments, buildings in use, construction sites and the deconstruction of buildings. More than 10,000 projects in around 30 countries have already received DGNB awards.

Advantages of DGNB certification

"The DGNB was founded at a time when no one knew what sustainability in construction meant. If you look at how far we have come as an association with our work, it is impressive. The best thing about it is that, as a member of the DGNB, it is possible to incorporate your own ideas in such a way that they have an impact."
Prof. Amandus Samsøe Sattler
DGNB President, co-founder and owner of studio ensømble berlin

More than green: our holistic approach to sustainability

Sustainable is the new normal: this is the motto the DGNB adopted in 2017 for its tenth anniversary. For us, sustainable building means more than green. Holistic and life-cycle oriented is the approach that the DGNB has always pursued. We have developed our own toolboxes on various key topics of sustainable building, which provide you with compact, practical entry-level aids.
