We, ClearVU Inspections, performed a one-point air tightness, blower door test on the
single family dwelling at 13 Glen Hall Drive, Queensbury, NY to determine the air
changes per hour on August 18, 2019. The dwelling was depressurized and the testing
procedure performed as per IECC— R402.4.1.2.
Test conditions were as follows:
Fan location -Side door ,� � ��11� 2� n�
442' above sea level �"'1'v
1511 CFM50
70°F outside air temperature
72°F inside air temperature
Pre-Test Baseline Building Pressure -0.1 PA
-50.0 Pa testing pressure
TEC DG-1000 & Model 3 Fan
Altitude Correction Factor= (1+(.000006 x altitude))x CFM50 = n/a
Results: (560 CFM50 x 1.000 x 60 Minutes)/(20,031 cubic feet) =
1.68 ACH50
IECC—R402.4.1.2-The building or dwelling unit shall be tested and verified as having an air leakage rate of not
exceeding 5 air changes per hour in Climate Zones 1 and 2,and 3 air changes per hour in Climate Zones 3 through
8.Testing shall be conducted in accordance with ASTM E 779 or ASTM E 1827 and reported at a pressure of 0.2
inches w.g.(50 Pascals).Where required by the code official,testing shall be conducted by an approved third party.
A written report of the results of the test shall be signed by the party conducting the test and provided to the code
official.Testing shall be performed at any time after creation of all penetrations of the building thermal envelope.
