Snøhetta is one of the partners in the Powerhouse project, along with the construction company Skanska, the environmental organization ZERO, the aluminium companies Sapa and Hydro, the consultancy company Asplan Viak, and the property management firm Entra Eiendom.
The team’s ambitious goal is to develop and construct buildings that produce more energy than they consume over the course of their lifetime.
Kjørbo is situated by the seafront in Sandvika in Bærum municipality outside of Oslo, Norway. The two renovated buildings were originally built in 1980 and each cover approximately 2 600 m2. Together they had an energy consumption of 250kWh per square meter annually.
After the renovation, the buildings' expected energy needs will be met by local production of solar panels. The solar panels can supply over 250.000kWh, or 41kWh/m2 each year.
Combined ventilation shaft and stairs.
A good indoor environment is important for the success of the project.
All interiors are upgraded into modern office spaces.
Walls, ceilings and windows are tight-fitting and well insulated. Exterior sun shading and internal solutions, including exposed concrete decks, contribute to a reduced cooling needs in summer.
