40 per cent less energy for air conditioning – what we can learn from the Vorarlberg Museum

How do you protect exhibits when the relative humidity is only allowed to fluctuate by ±3 per cent – without relying on more technology?

During the refurbishment and extension of the Vorarlberg Museum in Bregenz, architects, specialist planners and tradespeople found a surprisingly simple solution that reduces the need for climate control systems by a third and saves 40 per cent on annual energy costs.

Jan Hörster takes the audience behind the scenes of this extraordinary construction project. He demonstrates the challenges that had to be overcome and how an intelligent choice of materials interacts with cleverly selected building services. A talk on building physics, cost-effectiveness and the courage to rethink familiar solutions.
