Heat losses are slashed (by up to 90%) so that the amount of energy required to run the building is minimal, which in turn protects the occupants from ever increasing fuel bills and can provide a solution to combating fuel poverty. As well as savings on energy bills over the life of the building, investing in a high-quality build should result in less building defects and require less maintenance. The drastic reduction in energy needed to operate the building makes us less reliant on unsustainable fuel sources. If you prioritise drastically reducing energy, and then couple this with efficient renewable energy generation, it can provide a robust solution to meeting zero carbon targets and sustainable developments. Passivhaus provides a tremendous opportunity to tackle climate change. Proven Performance Crucially, Passivhaus buildings perform exactly as intended. All certified Passivhaus buildings undergo a rigorous compliance process to verify that the building meets stringent criteria. The Passivhaus certified seal of approval guarantees that the rigorous quality control processes have been followed correctly, which helps eliminate the performance gap. Over twenty years of experience demonstrates that the high levels of comfort and energy savings associated with the Passivhaus Standard is achieved through independent quality testing. 4 ECOBUILDER - THE SPECIFIER SPRING 2018

FEATURE ARTICLE: THE PASSIVHAUS TRUST Certification is also available to individual building products and professionals. Building products are categorised into 3 core areas: 1 – Opaque building envelope, 2 – Transparent building envelope, or 3 – Building services. Criteria requirements will vary for different climate regions for certification. As a guideline Passivhaus components are usually two to three times more efficient than the corresponding commonly used products. This high level of efficiency is critical to achieving the Passive House Standard. To find out more and how to apply please visit the Passivhaus components database. The Passivhaus Trust The Passivhaus Trust is an independent, non-profit organisation that provides leadership in the UK for the adoption of the Passivhaus standard and methodology.
