Sustainable and environmentally friendly 

The museum’s renovation relies on energy-efficient, climate-friendly solutions – not only during renovation, reconstruction and the construction of the new building, but also during operation once the project has been completed. To ensure that these targets can be met, several different aspects need to be addressed: building shape, energy supply, construction materials, HVAC and lighting technology. 

The replacement building will be constructed in line with the principles of sustainability. Studies at the beginning of the competition process showed that there is no preference for preservation or new construction in terms of sustainability over the entire life cycle. The solid construction will indeed bring about more grey energy during construction, but will make it possible to save energy on air conditioning during operation. Accordingly, sustainability was taken into account as a central suitability criterion throughout the entire competition process under the direction of Prof Brian Cody. 

Even today, Kunstmuseum Bern is already connected to the municipal district heating supply of Energie Wasser Bern. This efficient source of energy is to be guaranteed. 

The transformation of Hodlerstrasse will improve the urban climate. It will get less hot in summer thanks to the permeable surface. The new row of trees will also contribute to a more pleasant urban climate. Planted areas are envisaged for the museum square as well. There will be a gap between the new building and the Stettler Building which will allow cooler air from the slope of the Aare to flow into the city.
