Passivehaus

Achieving high energy efficient housing.

Developed in Germany, Passivhaus is now a worldwide recognised standard for extremely energy efficient homes.

Insulated Concrete Formwork (ICF) is ideal for helping projects achieve Passivhaus standards thanks to it’s many thermal benefits.

Passivehaus Standards.

What is Passivhaus?

Passivhaus is a low energy design standard that provides exceptionally comfortable buildings with minimum carbon emissions, developed in Germany by physicist Wolfgang Feist.

Key Characteristics

Excellent thermal comfort
Very low energy demand
Consistent fresh air throughout the building
High levels of insulation
Air tight design eliminating draughts
Minimal thermal loss through bridging

The UK building regulations are now following a similar path to the Passivhaus approach and the notional U value for walls of 0.18 W/mK is not that far above the maximum Passivhaus value of 0.15 W/mK. To achieve the Passivhaus standard the thickness of the External Wall Insulation required must increase from the 40mm, required to meet the Building Regs, up to 70mm and can be supplied by Polysteel.
