What is Passive House?
Passive House is focused on the health, comfort, durability, affordability, efficiency and predictability of our built environment.
Passive House is a cutting edge approach to design and construction, proposing to make sustainable design a proportionate response to the threat of climate change it dramatically reduces the energy used to operate a building while simultaneously enhancing the occupants' thermal comfort and raising the buildings' indoor air quality to an unsurpassed level.
The comprehensive methodology that is used produces a healthy, comfortable, long lasting, affordable and energy efficient buildings by focusing on a very clear and strict set of energy requirements.
Developed in the 1990s in Germany, the Passive House approach is growing exponentially in Euorpe and around the globe. The Passivhaus Institut (PHI) in Darmstadt Germany forms the scientific foundation for the Passive House approach. PHI has placed a premium on predictability and results, and research has shown (citation needed to cepheus) that PHouses do perform as calculated in the Passive House Planning Package (PH energy model) - making it a less risky than traditional "green" approaches.
Passive House can be applied to almost any building type, from single family homes, to apartment buildings to schools, factories, civic centers and fire houses - virtually anything is possible. Passive House doesn’t prescribe a style, a layout or any material - you are free to design what you want.
Additionally, the term Passive House can refer to three distinct things:
1. Passive House is an energy standard
an energy standard that results in up to 90% reduction in heating and cooling energy requirements.
2. Passive House is a methodology
a methodology that comprehensively addresses the full integration of building components, building science and comfort
3. Passive House is a certified building
In the United States the Passive House Institute U.S. in Urbana, Illinois is the certifying authority. If a building has not been certified it is not technically a Passive House and should not be advertised as such.
