Passive House certification is a rigorous quality assurance process that determines whether a building meets all of the requirements of the Passive House standard. More importantly, it confirms that the building has been designed to achieve high levels of occupant comfort and health and energy performance.
Max. 15 kWh/m2a OR Heating load max. 10 W/m2
Pressurization Test Result
@ 50 Pa
Max. 0.6 ACH (both over-pressure and under-pressure)
CanPHI strongly recommends a ‘pre-certification’ or ‘design stage review’ approach to certification – i.e. contact the certifier and have your design and PHPP reviewed well before you plan to start construction!!
All heating and cooling calculations are based on the net usable floor area of the building (the so-called Treated Floor Area (TFA) of any Passive House building). If cooling (air conditioning) is required, the annual cooling energy demand must also not exceed 15 kWh/m2
For details and requirements of how to Certify a Passive House building, please refer directly to one of PHI’s accredited Certifiers. Note that Certification is done remotely, and does not include either monitoring or site visits by the Certifier, so they can be based in any part of the world and still certify your project. Be warned that Certification is a rigorous and time-consuming process, which can add a significant extra cost to a small project.
