Why Passivhaus

Integrating Passivhaus standard principles into a building allows you to enjoy the following benefits:

Free of condensation, damp and mould at 17°+

Passivhaus requires all surfaces within the building envelope to remain above 17° Celsius without any input from the heating system. 17° is the dew point of water. As a result all Passive houses are free of condensation and resultant mould.


Triple glazed windows have excellent sound insulation qualities making Passivhaus an ideal choice for noisy locations that were previously deemed unsuitable for housing.

Go off-grid with renewables

Passivhaus is so efficient that it is possible to go off-grid with Heat Pumps and Solar Panels.

Uniform comfortable temperature

The MVHR system ensures that heat is spread evenly throughout the house. Triple glazed windows are free of any cold radiant effect. You can comfortably sit next to them in mid-winter.

Reduced heat demand = smaller heating system

The heating system in a Passivhaus is typically 1/4 the size of an that in an equivalent building.

High standard = low maintenance

Passivhaus is much more rigorous than traditional building. As a result the house will require less maintenance and repairs over time.
