About Passive House

Passive house (or PassivHaus) is a building standard which requires buildings to use very little energy for heating and cooling. Typically, a Passive House uses just 10% of the energy used by an ordinary house. Solar glazing is used to maximise height gain from the sun and because a Passive House is so well insulated and has so little heat-loss that the sun's rays bplus the heat produced by the occupants, electrical appliances and sunlight can build up enough to keep the building warm. Sophisticated heat-transfer ventilation systems are used to provide fresh air and prevent condensation without losing heat while adaptive shading and ventilation sytems plus good design minimises excess heat in the summer.
