German Sustainable Building Council (DGNB)
What if we were no longer allowed to build new structures? Questions like this - and many others - are raised in the exhibition What If: A Change of Perspective by the German Sustainable Building Council (DGNB). The DGNB is a non-profit association based in Stuttgart that has been advocating for future-oriented and responsible building for 18 years. With the DGNB Certification System, it has developed an internationally recognised planning and optimisation tool for assessing sustainable buildings and districts.

The exhibition invites visitors to question conventional ways of thinking and to rediscover the essence of sustainable architecture: buildings and districts that offer people a good home, remain affordable, and provide design-driven answers to the climate crisis. A central narrative traces the evolution of sustainable building, accompanied by six thematic sections and the award-winning projects of the German Sustainability Award for Architecture.
The Exhibition
What If: A Change of Perspective is a call to learn from past solutions rather than constantly reinventing the wheel. Exemplifying this are the previous award-winning projects of the German Sustainability Award for Architecture, which the DGNB has jointly awarded with the German Sustainability Award Foundation every year since 2013. In the exhibition, these projects are presented through models, photographs, and images, each assigned to one of the six thematic areas.
