What is Passivehaus?

Passivehaus certification is an internationally recognized high performance-building standard developed in Germany that focuses on the design, construction and operation of energy efficient buildings.

Buildings designed and constructed to the Passivehaus standard are characterized by high levels of comfort with low energy consumption – up to 90 percent less space heating and energy consumption than conventional buildings – hence the term “passive” as they need little active heating or cooling to stay comfortable throughout the year.

This is achieved by design that minimizes air leakage through the building envelope (e.g. windows, insulation, heat recovery ventilation), while maintaining indoor air quality and thermal comfort.
