About the Passivhaus Trust

The Trust is an independent non-profit organisation that provides leadership in the UK for the adoption of the Passivhaus standard and methodology. Its aim is to promote Passivhaus as a highly effective way of providing high standards of occupant comfort and health without compromising on slashing energy use and carbon emissions from buildings in the UK. Improving efficiency is crucial to meeting Climate Action Targets.

Passivhaus is the leading international low energy design standard. With over 65,000 buildings completed to this standard across Europe, it offers a robust, proven and cost-effective method to help the UK achieve its challenging carbon reduction targets for the built environment sector.
