What is a Passive House?

What is a Passive House?
A Passive House is a rigorous, voluntary standard for energy efficiency in a building, which reduces the building’s ecological footprint. It results in ultra-low energy buildings that require little energy for space heating and cooling.
 
Passive House buildings save energy and reduce greenhouse gases – not just a little but a great deal. They allow for heating and cooling related energy savings of up to 90 percent compared with typical building stock and over 75 percent compared with average new builds. In terms of heating oil, Passive House buildings 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.
 
They’re a building standard that is truly energy efficient, comfortable, affordable and ecological at the same time. Passive House is not a brand name, but a construction concept that can be applied by anyone and that has stood the test of practice.
 
Passive House buildings are also praised for their high level of comfort. They use energy sources inside the building such as the body heat from the residents 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 walls, roof and floor slab keep the heat during winter in the house – and keep it out during summer.
 
Are Passive House buildings a good investment? Passive House buildings not only save money over the long term, but are surprisingly affordable to begin with. The investment in higher quality building components required by the Passive House Standard is mitigated by the elimination of expensive heating and cooling systems.
