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.
