WHOLE BUILDING AIR -LEAKAGE TEST
REPORT
Scope of work:
Whole building air -tightness test conducted at 1715 0 Ave, Anacortes, WA.
Test date:
03/26/2022
Testing Summary: 1
Evergreen Certified, LLC. was contracted by Madrona Real Estatt Services, LLC. to
perform Whole Building Air Leakage Testing in accordance with ASTM E779 per the
requirements specified by the 2015 Washington State Energy Code, Commercial
Provisions section C402.5: Air leakage -thermal envelope.
The building was tested using pressurization and depressurizatibn with a final
combined result of 0.306CFM/Ft2 of envelope at 75Pa with the c6de maximum
allowable air leakage rate of the building envelope at 0.40 CFM/>~t2 of at 75Pa.
The test was performed in accordance with the attached report.

Fan Pressure FP is the measured fan pressure when using a self -referenced fan or when Room Pressure (RP) is
( )
negative. If using a fan which is not self -referenced, and Room Pressure is positive, Fart Pressure is calculated by
subtracting the measured Room Pressure from the Absolute Value of the Fan Pressure.
If PrA>0 and fan is not self -referencing: FP = PrB I-PrA
If PrA<0 or fan is self -referencing: FP = PrB
Flow calculations are not valid if Fan Pressure is less than either IVIF or (K2 x I RP 1).
Flow in CFM using the above coefficients is calculated as follows for standard Ranges:
flow = (FP — (IRPI x K1) )N + (K + (K3 x FP))
Flow in CFM using the above polynomial coefficients is calculated as follows:
f low = (a x W) + (b x W) + (c x FP) + d + ((g — ARP I) x f )

Discussion of Results
Leakage rate
The measured air flow at a test pressure of 75 Pa was 8580.5 CFM which equates to a In equivalent leakage area
of 706.1 sq in, based on adding up the leakage from all the holes and cracks in the exterior.
This leakage also equates to a one inch gap, 58.84 feet long. Your home leaks as if there is one hole this size in
the wall.
