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.
In 2026, we expanded the DGNB Sustainability Day for the first time by adding a networking event on the evening before.
Save the Date
2027 is a special year for the DGNB. At the DGNB Sustainability Day on 29 and 30 June 2027, we want to look back and celebrate "20 Years of DGNB" with you – but above all, we want to turn our attention to the future. Therefore, you are warmly invited to Berlin for the DGNB community’s main event in this anniversary year.
As usual, you can look forward to a varied programme. And, as in previous years, the association’s general assembly will take place as part of this major networking event.
