Villa Nyberg is an part of the first series of Sweden passive houses designed Kjellgren Kaminsky. It’s designed as environmentally friendly house and is situated in Borlänge, central Sweden. The idea of passive houses is based on the knowledge that people and household equipment generate a lot of energy. That’s why passive houses are extremely well-insulated buildings that are largely heated by the energy already present in the building. Energy simulations shows that Villa Nyberg will have an energy consumption for heating of only 25 kWh/m²year. Reduced heat loss is an another important feature of the house. The round shape of the villa eliminates coldbridges and reduces the enclosing wallarea of the house. It also effects the way you live in the house, during the day one will move from room to room around the building experiencing different views and daylight conditions.
