Kistefos Museum is an exhibition building located in a museum parc in Norway. The building is designed as a bridge structure and cladded with glass and metal facades, flat and double curved Due to the steel bridge structure and extreme weather conditions the facades and water membranes has been designed to large deflections and thermal movements. The entire facade geometry is defined in Grashoppr scripting, combined with similar scripting from the structural engineer and architect. This was the only way to efficiently update and control the design through the optimization stages of the steel structure.
Both the glass and metal facades are challenged by a double curvature in the twisted center part of the building and all build-up and substructures for both glass and opaque facades are bespoke designed systems. The weather layer is covered by an outer metal skin. Due to heavy snow build-ups 4 months a year the two layer facade build-up has been specifically designed to avoid ice build-up between the layers.
