The project is a collaborative scheme in which Snøhetta has worked with the construction company Skanska, the environmental organization ZERO, the aluminum companies Sapa and Hydro, the consultancy company Asplan Viak and the property management firm Entra Eiendom with the aim of renewing a group of offices in Kjørbo, a seaside town in the municipality of Bærum, outside Oslo. By optimizing and combining existing technologies in new ways, the two office buildings from the 1980s were renovated into positive-energy buildings: insulating the walls and ceilings, replacing the frames (and therefore reducing the cold bridges), controlling sunlight in summer with automated shading screens, zoning the plans and sensors to control the need for light and air conditioning, using geothermal systems for heat/cooling, and reducing the speed of hot and cold air supply. All the materials used meet the highest environmental standards, and are low in embodied energy. Furthermore, they fulfill the aesthetic function of blending with the adjacent buildings. The facades are covered with charred wood, which retains the dark colors of the existing building.
