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.
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.
Quiet
Triple glazed windows have excellent sound insulation qualities making Passivhaus an ideal choice for noisy locations that were previously deemed unsuitable for housing.
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.
Go off-grid with renewables
Passivhaus is so efficient that it is possible to go off-grid with Heat Pumps and Solar Panels.
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.
