|By optimising and combining known technology in new ways, ordinary office buildings from the 1980s can produce more renewable energy than they consume during their lifetime. This is the case for Powerhouse Kjørbo, where a total rehabilitation of the two first office buildings has resulted in Norway’s first energy-positive office building, and probably also the first renovated energy-positive building in the world.
After the renovation, the buildings’ energy need has been reduced by more than 86 percent. This has been made possible by minimising the energy needs inside the buildings and by generating more renewable energy on site than the buildings consume during their lifetime. The energy accounts include energy consumption related to production of building materials, construction, operation and demolition of the building.
