Passivhaus Principles – a primer

As awareness of the Passivhaus standard has grown, so has appreciation of the underlying principles of building fabric: insulation, airtightness, ventilation, high-performance windows, and minimised thermal bridging. This must be seen as a positive. However, these five principles are only part of the story.

The reliable performance and wide-ranging benefits that Passivhaus is renowned for can only be delivered by taking an integrated approach that also encompasses these three core principles:

• detailed performance and comfort criteria
• modelling in the Passivhaus Planning Package (PHPP), and
• rigorous quality assurance across design, construction and commissioning.

This 2-page primer introduces the Passivhaus standard and sets out all eight underlying principles.
