Abstract:Air exchange rates were measured repeatedly in seven Fairbanks buildings throughout the 1982-1983 winter. These buildings ranged from small private homes to medium sized grade schools. Only the two grade schools had mechanical ventilation systems. Two air exchange measurement techniques were used, the ASTM Standard Leakage Rate by the Sulfur hexafluoride (SF6) Tracer Dilution Method and the continuous sampling method developed by Brookhaven National Laboratories (called AIMS). The AIMS method yielded somewhat lower air exchange rates than those measured by the SF6 method. It gave integrated 22 and 33 day air exchange rates ranging from 0.06 to 0.67 air changes per hour (ACPH). Average air exchange rates with the SF6 method ranged from 0.14 to 1.71 ACPH. There was no apparent correlation between air exchange rate and time of year, relative humidity or inside versus outside temperature difference. The effect of wind was not evaluated because wind speed was rarely high enough to be measurable. Air exchange rates measured in buildings without mechanical ventilation systems were considerably lower than those reported in the literature for buildings elsewhere in the United States.
