What is Passivhaus?
Passivhaus (Passive House) is the world's leading standard for energy-efficient building design. A Passivhaus building uses up to 90% less energy for heating and cooling than a conventional building, achieving exceptional comfort levels through careful design rather than complex mechanical systems.
The standard focuses on five key principles: superior insulation, airtight construction, thermal bridge-free detailing, high-performance windows, and mechanical ventilation with heat recovery.
