What if we weren't allowed to construct new buildings anymore? What if the climate crisis had already caused a 3 °C rise in global temperature by now? And what if we honestly asked ourselves how much space and comfort we truly need? Questions like these are the starting point for the exhibition 'What If: A Change of Perspective', curated by the DGNB.
What is the 'What If: A Change of Perspective' exhibition about?
We are inviting you to Aedes to question established ways of thinking and acting and be open to new perspectives. In the process, you are introduced to the idea at the heart of building sustainably: designing good buildings and neighbourhoods that people feel comfortable in, that are affordable, and that provide answers to the most pressing environmental issues at the same time.
The exhibition illuminates how multifaceted the topic of sustainable architecture is, and highlights the developments in this field over the past few decades. It suggests ways that everyone can contribute to change – without pointing fingers. The exhibition is also a call to learn from good solutions from the past, instead of constantly reinventing the wheel. This is exemplified by the projects that have won the German Sustainability Award for Architecture since it was created in 2013.
In this sense, 'What If: A Change of Perspective' is also a plea for an open, honest look at what's possible if we're prepared to think differently. And an invitation: to rethink, to think over, to think ahead – so that together we can create a built environment that's liveable and future-proof.
The exhibition is bilingual: German and English.

You would like to know more about sustainable building and the DGNB? On selected days, representatives of the DGNB will be on site from 4:30 p.m. and will be happy to answer any questions you may have.
A second exhibition at Aedes, 'Democratic Design: Space for Cooperation, Collaboration and Compromise', will be running concurrently to the DGNB exhibition for its entire duration. With an international audience in mind, both exhibitions are in English as well as German. The exhibitions are aimed at anyone interested in architecture, regardless of how much they already know about issues relating to sustainable building.
