Ever wondered if your heating or air conditioning in your house is really necessary? Passive House (Passivhaus) is a design approach to buildings that reduces the energy required drastically. This video explains briefly in 90 seconds how it's done.
Passive House (Passivhaus) is considered to be the most rigorous voluntary energy-based standard in the design and construction industry today.
Passive House (Passivhaus) buildings consume up to 90 percent less heating and cooling energy than conventional buildings. Applicable to almost any building type or design, the Passive House high-performance building standard is the only internationally recognized, proven, science-based energy standard in construction.
*All heating and cooling calculations are based on the net usable floor area of the building. If cooling (air conditioning) is required, the annual cooling energy demand must also not exceed 15 kWh/m2
From the outside, Passive Houses are no different from conventional houses, because the term “Passive House” refers to a standard and not a certain construction method. Good planning and careful implementation of details are decisive factors in the construction of Passive Houses.
The quality of the building envelope and building services is crucial for a Passive House. The Passive House Institute (PHI) provides certificates which make it easier to ensure a high standard of implementation.
