Powerhouse Kjørbp - Bærum - Norway
Powerhouse Kjørbo are two ordinary office blocks from the 80s that are transformed into contemporary and modern office space.
The aim is that the buildings over a lifetime will produce more energy than they use. Using solar cells will Powerhouse Kjørbo produce over 200,000 kWh per year.
The power can be supplied to the technical installations in buildings and at times also to the mains. The multidisciplinary design process right from the start has helped new and innovative solutions.
For the design phase, the project received BREEAM NOR certification Outstanding.
Powerhouse Kjørbo is the first project Powerhouse cooperation has carried out, and it is the first time a building being rehabilitated to energy-positive buildings. The method can be easily transferred to other offices.
Solar cells - electricity (photovoltaic plants), heat pump water-water (energy wells for cooling / heating, heat pumps. 100 percent coverage,also of tap water (own VP), heat pump water-water (condenser heat from the cooling of server equipment used for heating), remote - / local heating (backup in case of failure of the heat pump).
