What is Passivhaus?

‘Passivhaus’ also known as ‘Passive House’, is a low energy construction standard. It was developed in the 1990s by Dr Wolfgang Feist, who was concerned that buildings consumed much more energy when built than was predicted at the design stage.

As such, a Passivhaus building requires very little energy for heating or cooling, whilst providing a high level of comfort for the occupants. Attention to detail, rigorous design and construction and an exacting certification process ensure that what is designed is built, and what is built performs as it was designed.

This is achieved primarily through a fabric first approach, meaning high levels of thermal insulation, high levels of airtightness and the use of whole house Mechanical Ventilation with Heat Recovery (MVHR).
