| Abstract | Whole-house and inter-zonal ventilation rates are important parameters to understand energy efficiency and indoor air quality. Under occupancy, passive sampling using thermal desorption (TD) tubes is more desirable due to its simple and less obtrusive nature. In this research, the uptake rates of six perfluoro-carbon tracer (PFT) gases were determined in a laboratory setting for 4 to 7-day passive sampling on two types of TD tubes. The sources of PFTs were manufactured and their stability were investigated for 4 months. The passive method was validated against the SF₆ decay method and applied to determine inter-zonal air flows in a research house. The air change rates measured with the passive release and sampling of PFT gases were comparable to those from the SF₆ method. This study shows that the passive uptake rates determined in a chamber and PFT sources manufactured in-house can be useful to measure the inter-zonal air flows in homes under occupancy. |
