The buildings are designed to conserve energy and are primarily heated by heat pump and ground-source technology, recycled surplus heat plus solar energy. The electricity to power lighting, processes or to produce supplementary heat, is provided by a windmill located at the coast, in which the building proprietor has an ownership interest, and by Statoil which supplies green electricity.
The buildings for Ford, McDonald’s and Statoil are linked by culverts that make it possible to recycle surplus energy in the form of heat from McDonald’s hamburger grills and deep-fryers as well as heated coolant water from Statoil’s refrigeration system. The surplus energy is transported to the heat pump in the car dealership thus allowing all buildings to benefit from the energy surplus. The result is efficient energy use and resource conser vation.
