ClearVU Inspections, performed a compartmentalized one-point air tightness, blower door test on the
building unit identified as 80 Main Street, Apt 211, Queensbury, NY, to determine the air changes
per hour on April 14, 2024. The building was depressurized and the testing procedure performed as
per ICC–380.4.3.2.
Test conditions were as follows:
Fan location - Unit B entry Door
400’ above sea level
621 CFM50
45°F outside air temperature
60°F inside air temperature
Pre-Test Baseline Building Pressure -1.5 Pa
-50.0 Pa testing pressure
TEC DG-1000 & Model 3 Fan
Boundary Area Calculated via architectural plans
Altitude Correction Factor = (1+(.000006 x altitude)) x CFM50 = n/a
Results: ( 621 CFM75 x 0.985 ) / ( 1,797 boundary area) =
0.340 cfm/ft2
IECC – C402.5 - The thermal envelope of buildings shall comply with Sections C402.5.1 through C402.5.8, or the building thermal envelope shall
be tested in accordance with ASTM E 779 at a pressure differential of 0.3 inch water gauge (75 Pa) or an equivalent method approved by the code
official and deemed to comply with the provisions of this section when the tested air leakage rate of the building thermal envelope is not greater
than 0.40 cfm/ft²(2.0 L/s ⦁ m²). Where compliance is based on such testing, the building shall also comply with Sections C402.5.5, C402.5.6 and
C402.5.7.
During testing:
1. Exterior windows and doors, fireplace and stove doors shall be closed, but not sealed, beyond the intended weather stripping or other
infiltration control measures;
2. Dampers including exhaust, intake, makeup air, backdraft and flue dampers shall be closed, but not sealed beyond intended infiltration control
measures;
3. Interior doors, if installed at the time of the test, shall be open;
4. Exterior doors for continuous ventilation systems and heat recovery ventilators shall be closed and sealed;
5. Heating and cooling systems, if installed at the time of the test, shall be turned off; and
6. Supply and return registers, if installed at the time of the test, shall be fully open.
