Developed in Germany in the 1990s, Passivhaus (or ‘passive house’) is a quality assured standard and methodology for low energy building, which can help create buildings which use around 75% less energy than standard practice for UK newbuild.
Key Passivhaus features
- Super insulation
- Stringent levels of airtightness
- Minimal thermal bridging
- Optimisation of passive solar gain
- Mechanical ventilation with heat recovery

What is Passivhaus? Guidance from the Passivhaus Trust www.passivhaustrust.org.uk/what_is_passivhaus.php
Average UK dwelling stock uses energy at a rate of 278 kWh/m2/annum (Source: AECB yearbook – the Sustainable Building Guide – 2006/7) and space heating makes up 56% of all domestic energy use. (Source: DECC 2007 figures).
Passivhaus houses use around 90% less energy for space heating than the average UK home (15 kWh/m2/annum, as opposed to 155.68 kWh/m2/annum for average dwelling stock). Space heating needs for Passivhaus are 15 kWh/m2/annum.
