The resource sets out the PEP partners' proposals for certification of
PassivHaus dwellings. The report identifies the benefits of a 'supply chain' approach for certification, which involves certification, and hence the control of quality, of the design process, the construction process, and the post construction inspection and testing of a PassivHaus. However, the PEP partners recognise that with the current state of the PassivHaus market, it would be difficult to introduce such a 'supply chain' approach in many
countries. The PEP partners have, therefore, also proposed a simpler scheme for the current emerging market scenario. This scheme involves the verification of the 'as built' design in accordance with the Passive House Planning Package (PHPP) by a competent PEP partner and confirmation of the airtightness of the completed building by a fan pressurization test performed in accordance with EN 13829 by an accredited organisation or
an organisation recognised as competent by the PEP partner.
This report recommends that the supply chain certification approach should be used if possible and when the market becomes sufficiently developed. This approach, if adopted, would allow any certification body with an interest in certification of PassivHaus dwellings to gain accreditation for these activities. This will provide an open market and competition for
certification services, while enhancing security and the management of risk for all those involved
