SUMMARY OF TESTING AND RESULTS
On February 12, 2024, QED LAB performed a computer
automated air exfiltration assessment at the Port of Edmonds
project. The project is located at 471 Admiral Way in
Edmonds, Washington.
QED LAB performed airflow measurement on the new
structure. Not all features of the building were included within
the test area. Testing methodology was in conformance with
ASTM E 779: Standard Test Method for Determining Air
Leakage Rate by Fan Pressurization per the Washington State
Energy Code.
Target Leakage Rate: 0.250 CFM/SF
Allowable Leakage Rate
Not to Exceed:
6,718 CFM

Testing was performed utilizing a calibrated Retrotec blower door
system which consisted of one (1) DM32 Controllers and one (1)
3300SR fan systems with accessories. Prior to testing, all equipment
and flow measurement instrumentation was calibrated as required.
Installation of this system is shown to the right. Testing was
performed utilizing positive pressurization (exfiltration).
A total of one (1) formal test was performed to determine air leakage
within the test area. Testing showed acceptable results per the project
specifications and the Washington State Energy Code for the positive
pressure test, resulting in a pass.
Some features of the building were excluded from the test, including
but not limited to: bathroom vent and range hood. In addition, all
exterior doors were closed and locked, as well as all interior doors
propped open in order to achieve pressure equalization within the
conditioned space. Representative sample photos of these isolations
and building preparation are included on this page.

Technicians performed a 75 pascal positive pressure test and recorded an air leakage rate of 0.245 CFM/SF at 6,577
CFM. Areas of air leakage were minimal and are estimated at 4.90 square feet in total. The leakage rate per square foot
at 75 pascals (1.57 PSF) was less than the maximum allowable leakage rate per the project specifications, resulting in a
pass for this test.
The chart on the right shows gauge pressure
during the test in +/- 15 second intervals. A base
reading was recorded over the first 45 seconds
in order to determine bias pressures (mostly
caused by wind) to allow the software to adjust.
Technicians record CFM in stepped pressures
from 35 pascals up to 75 pascals in 5
increments. At the end of the pressure test,
technicians took another round of base readings
to ensure accuracy by balancing bias pressures.
The chart shows all the measurements taken
during the test. This procedure is typical on all
tests performed at this project. The chart below
shows gauge pressure vs flow. This comparison
shows volumes of air as related to pressures
achieved in the building.
Note:
The weather at the time of testing was
moderate winds (see weather information within
this report), which creates for unstable
pressures in the building. These unstable
readings are balanced using bias pressure
readings and averaging hundreds of pressure
and flow calculations to determine a leakage
rate at 98.9% accuracy.

The above charts show specific fan and pressure gauge equipment and range plate settings as used in tests at this
project. Calibrations are performed by the product manufacturer (Retrotec) and the accuracy of range plates are
determined by the testing agency directly related to the area of air barrier. The fan utilized the "Open" range plate setting
for a maximum flow of 8,300 CFM. The fan used for these tests was a 3300SR model.
Weather conditions for Monday, February 12,
2024, are identified on the chart to the right.
Bias pressures such as wind can create
unstable building pressures, therefore recording
the weather activity aids in eliminating those
bias pressures from the building airflow
calculations.

COMMENTS
The Washington State Energy Code and ASTM E 779 testing standards normally require testing with positive and
negative pressures and recording both test results. In our experience, testing with negative pressure on this type of
building with exposed interior -faced insulation creates damage, as well as opens up an avenue for air leakage. This can
have effects on the air leakage, leading to false results. See photo of exposed interior -faced insulation, below.
The Washington State Energy Code allows for testing using positive pressure only per section C402.5.1.2, Subparagraph
1 (Test shall be accomplished using either (1) both pressurization and depressurization or (2) pressurization alone, but not
depressurization alone). The decision to test using positive pressure is in compliance with the Washington State Energy
Code and ASTM E 779 testing standard.
