Certification

Buildings: All proposed Passivhaus designs must undergo energy modelling conducted via the Passivhaus Planning Package (PHPP.) Tests ensure these targets are met, completing the quality assurance process. A certificate is only issued if the exactly defined criteria have been met without exception. Learn more about the different classes & certification process for Passivhaus buildings.

Designers: Certification for designers/ consultants who have the expertise to deliver Passivhaus buildings. The qualification covers training on PHPP, a design tool used to inform the design process and to assess or verify compliance with the Passivhaus Standard. If you can't find a UK consultant via our members map - check a list of international certified designers here.

Tradespeople: Contractors have developed their basic building knowledge & understand key Passivhaus principles such as airtightness. If you can't find a UK contractor via our members map - check a list of international certified tradespeople here.

Components: Certified products have undergone independent uniform testing. This allows useful quick comparisons and eases the task for designers to confidently specify high-quality, energy-efficient products. Check the database of certified Passivhaus components.
