What is a Passive House?
A Passive House is a construction standard which achieves extraordinarily low energy consumption. Occupants of a Passive House enjoy excellent comfort conditions and high indoor quality during both winter and summer.
Typically this requires high insulation levels, very good building airtightness and a simplified heating and - if necessary - a cooling system. Excellent indoor quality is guaranteed by a mechanical ventilation system with highly efficient heat recovery.
Passive House – a leading concept for
- Thermal bridge free design
- Airtight construction
- Heat recovery ventilation
- Highly insulating windows
- Innovative building services

Why Build Passive Houses?
The Passive House standard offers a cost-efficient way of minimizing the energy demand of new buildings in accordance with the global principle of sustainability, while at the same time improving the comfort experienced by building occupants.
It thus creates the basis on which it is possible to meet the remaining energy demand of new buildings completely from renewable sources - while keeping within the bounds set by the limited availability of renewables and the affordability of extra costs.
But the most important argument:
Every Passive House is also an active contributor for climate protection.
