DGNB Sus­tain­abil­ity Day

The DGNB Sustainability Day is the central event for everyone interested in sustainable building. It's the ideal opportunity to look at things from a different angle, forge valuable contacts and initiate potential partnerships. With a mix of formats, topics, ideas and people, one thing’s certain: wherever you join us from, it’s a day brimming with novel ideas. And if you recently joined us as a DGNB member, the day is ideal for exchanging views and networking with other DGNB members.

The event always begins with the association general assembly. It is here we present all key information on recent developments at the DGNB and new topics we’re working on. Every two years, DGNB Members elect the association's Board of Directors. This part of the event is open exclusively to the employees of DGNB Members.

This year, DGNB Sustainability Day took place on 25 June 2025.
