Certification process

We recommend contacting a certifier* early on in the planning process. Any problems identified by the certifier can be easily corrected at this point in time. In principle however, 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 (airtightness test, documentation of flow rate adjustment, construction manager's declaration) will be checked during the final inspection.

*The Passive House Institute itself carries out building certification. For a quotation, please contact us at: building.certification[at]

If all criteria are met, the building owner will receive the following:
