DGNB Annual Congress

The two-day digital congress highlights current developments around sustainable building

Sustainable building means diversity - diversity of possibilities, of perspectives, of people. Our Annual Congress on 27-28 February 2024 focused on this very diversity. The event assessed where we are at the start of 2024 in terms of sustainable building and discussed promising ways forward for a sustainable future for the building and real estate sector. Keynote speeches offered inspiration and opened our eyes to what is possible. Discussion panels in themed rooms brought together expertise on the key challenges facing the industry. Two days of sustainable building in all its facets, perspectives and options.

You will soon be able to watch all the keynote speeches and discussions from the themed rooms on the DGNB YouTube channel.

“PLAN B not Planet B” (Keynote in English)

It is increasingly clear that the green movement has not progressed as planned. While more spending are spent on green solutions, “business-as-usual” has not been tackled adequately to shift the needle of sustainability. There is now an urgent need to find PLAN B to achieve a more workable solution. AI and machine learning are new entrants to the formula. Applied correctly, it would bring fresh perspectives as part of PLAN B.

Sustainable finance: the role of banks and insurance companies in transforming the built environment

Health in buildings: How to design, build and operate allergy-friendly buildings
