What's a Passivhaus?

Passivhaus is a rigorous German standard for low energy homes. By insulating a building and making it completely draught free, it virtually eliminates heat loss and creates a building with very low impact on the environment. The majority of heating required comes from ‘passive’ sources such as sunlight, emitted heat from electrical appliances, heat from the ground, heat loss from the hot water tank, and even bodyheat, meaning almost no extra heating energy input is required.

Fresh air......

A Passivhaus has more fresh air than traditional construction techniques. With a mechanical ventilation system supplying a continuous stream of pre-warmed fresh air, your building will be healthy and free of humidity and its associated mould problems.

A Passivhaus is an extremely low energy building. By creating an highly insulated airtight space and utilising MVHR (Mechanical Ventilation with Heat Recovery) technology to manage the airflow through the building, the energy requirements can be efficiently controlled to deliver an extremely quiet and comfortable living environment whilst needing only a fraction – as little as 8% – of the energy required to power a Victorian house.


As well as being low energy, through controlled ventilation a Passivhaus can create an optimum living environment by regulating temperature, humidity and noise levels which creates unparalleled levels of comfort and tranquillity.


The heat and hot water requirements for the house are supplied by low-energy solutions such as Solar Thermal and MVHR (Mechanical Ventilation Heat Recovery) with any remaining electricity requirements either being taken from the grid or (depending on suitability) technologies such as Photovoltaic solar panels or wind turbines.
