AbstractThis paper provides a comparison of the air change rates measured by perfluorocarbone tracergas (PFT) and SF6 tracer gas decay, and the house airtightness measured by a blower doorduring the winter season of 2008-09 in 68 homes in Québec City, Canada. The average airchange rates for all the homes were similar for SF6 and PFT, however the individualmeasurements did not correlate well. A better inverse correlation was obtained betweenmeasured formaldehyde concentrations and the air change rates based on PFT measurementsthan those based on SF6 measurements. Using on the PFT measurements, 83% of the homesdid not achieve the nominal guideline of 0.35 air changes per hour for residential buildings.
