ClearVU Inspections, performed a one-point air tightness, blower door test on the single family
dwelling located at 11B James Place, Queensbury, NY, to determine the air changes per hour on
February 02, 2024. The dwelling was depressurized and the testing procedure performed as per IECC
– R402.4.1.2.
Test conditions were as follows:
Fan location - Rear Door
350’ above sea level
619 CFM50
43°F outside air temperature
39°F inside air temperature
Pre-Test Baseline Building Pressure .05 Pa
-50.0 Pa testing pressure
TEC DG-1000 & Model 3 Fan
Altitude Correction Factor = (1+(.000006 x altitude)) x CFM50 = n/a
Results: ( 619 CFM50 x 1.000 x 60 Minutes) / 14,256 cubic feet) =
2.557 ACH50
