The PH Certification Process
Buildings meeting the strict Passive House certification criteria can be certified as Passive House buildings by any of the Passive House Institute accredited Building Certifiers operative worldwide.

APHA recommend contacting a Passive House Certifier early on in the planning process, where any problems identified can be easily corrected at this point in time. In principle, certification can also be applied for after completion of the building.

As a rule, all energy-relevant planning documents and technical data of the construction products are submitted before the start of construction work. After careful checking and comparison with the energy balance calculation, the certifier will provide information about any necessary corrections.

After completion of the construction, any changes in the planning will be updated and documents relating to construction will be checked during the final inspection.

As an independent authority, the Passive House Institute tests and certifies products based on their suitability for use in Passive Houses. Products that carry the “Certified Passive House Components” certificate have been tested according to uniform criteria; they are comparable in terms of their specific values, and are of excellent quality regarding energy efficiency. Their use facilitates the designer’s task and significantly contributes to ensuring the faultless functioning of the resulting Passive House.
