Passivhaus building certification
The Passivhaus Standard is voluntary and based purely on building physics which applies to both domestic and non-domestic buildings. The criteria for Passivhaus certification are performance based, instead of individually specified construction or technical details. Certification requires that overall planning is carried out with a calculated energy assessment within the Passive House Planning Package (PHPP), plus elaboration of the details and supporting documentation on components and services. This ensures that the planned building will actually perform as designed.
Certification is intended to ensure a good quality of work. Airtightness, thermal bridges, the quality of the windows and their installation, the ventilation system and other building services will all be checked as part of the project. The main factor in successfully achieving certification is planning, as only careful and considered planning will ensure you complete all the required factors to achieve the Passivhaus standard.
The QA certificate
After the building has successfully achieved the required airtightness level and the commissioning of the building services has been completed, the project is assessed and checked as part of the final quality assurance check, or Certification. Upon successfully achieving all criteria the building certifier will issue the ‘Passivhaus Quality Assurance Certificate’ to the design team or client.
