The definition of passive house is based on its extremely low energy need. Passive houses consume less than quarter of the energy required for a standard building. They have no separate heating systems apart from heat recovery ventilation. The efficiency is based on well-insulated and air-tight passive building envelope solutions.
The structures are designed and built without any cold bridges that reduce heat insulation. The building’s outer shell is air-tight and the microclimate is draught-free and evenly warm. The high annual utilisation rate of heat recovery in ventilation guarantees only minor heat losses in ventilation. The remaining small energy need for heating can be covered using simple building system solutions.
The technology harnessing the world in which we live
The Passive House is not an energy standard but an integrated concept assuring the highest level of comfort.
