Passive House is fundamentally about design. It is best approached as an integrated design process with the whole design team involved. As a fabric-first construction standard summarised by 5 design principles and performance criteria, it ensures a design delivers very high performance and comfort for the lifetime of the building, plugging the “Performance Gap” often experienced in building operations.

It relies on building physics and carefully integrated, minimal building services and technology. By eliminating the need to bolt expensive additional technology onto a poorly performing building, it eliminates the risk of bolt-on green-bling compromising the architecture.
