A Passive House / Building is a building standard that is energy efficient, comfortable, affordableand ecological ALL at the same time.
Passive House / Building is not a brand name, but a construction concept that can be applied by anyone and that has stood the test of practice and literally thousands of years of time. These are modern, beautiful, high-value homes.
Passive Buildings allow for heating and cooling related energy savings of up to 90% compared with typical building stock and over 75% compared with average new builds. In terms of heating oil, Passive Houses use less than 1.5 litres per square meter of living space per year – far less than typical low- energy buildings. Similar energy savings have been demonstrated in warm climates where buildings require more energy for cooling than for heating (thermal mass).
Passive Houses are also praised for their high level of comfort. They use energy sources inside the building such as using the heat from an oven or solar heat entering the building – making heating a lot easier.
Appropriate windows with good insulation and a building shell consisting of good insulated exterior thermal mass walls, roof and floor slab keep the heat during winter in the house – and keep it out during summer.
Ventilation consistently supplies fresh air making for superior air quality without causing any unpleasant draughts. This is a guarantee for low Radon levels and improves health conditions.
