Our featured home is this beautiful Passive House in Comox BC, located on Vancouver Island. The home was designed by Mark Ashby at Fold Architecture, and constructed by Griffith Homes.
The Passive House building standard is established by meeting rigorous energy performance metrics. If we were to compare this home to the BC Energy Step Code, the home would easily reach Step 5.
Passive House air tightness testing uses a slightly different methodology for testing protocols, compared to the ERS (EnerGuide Rating System). With the Passive House Standard (EN13829), we preform two tests, a depressurization test and a pressurization test, then take the average of both scores. The HRV supply and exhaust vents are also sealed for the test. With the ERS standard (CGSB), we test the house as operated, meaning no sealing of any ductwork or penetrations during the final testing, and only a depressurization test is performed.
This home tested extremely well at 0.21 ACH @ 50Pa ( ACH = air changes per hour). The Griffith homes crew did an amazing job with this custom home!

Fan Depressurization
A process by which a large fan exhausts air from a building and creates a pressure difference across the building envelope. An analysis of the flow rate through the fan at different pressure points provides a measurement of air tightness.
