Sample Questions

Question 1
What is the primary purpose of a continuous air barrier in a building enclosure?
To control the unintended movement of air into and out of the building enclosure
To provide structural support for the exterior cladding
To act as the building's primary thermal insulation
To reflect solar heat away from the wall assembly
Question 2
Under most North American codes, the maximum air permeance allowed for an individual air barrier MATERIAL when tested to ASTM E2178 is:
0.2 L/(s·m2) at 75 Pa
0.02 L/(s·m2) at 75 Pa
2.0 L/(s·m2) at 75 Pa
0.0004 L/(s·m2) at 75 Pa
Question 3
An air barrier ASSEMBLY tested to ASTM E2357 must have a maximum air leakage of:
0.02 L/(s·m2) at 75 Pa
0.40 cfm/ft2 at 75 Pa
0.20 L/(s·m2) at 75 Pa
0.10 L/(s·m2) at 75 Pa
Question 4
In the 2021 IECC, the maximum measured WHOLE-BUILDING air leakage rate for commercial construction is:
0.40 cfm/ft2 at 75 Pa (0.3 in. w.g.)
0.25 cfm/ft2 at 50 Pa
0.60 cfm/ft2 at 75 Pa
0.04 cfm/ft2 at 75 Pa
Question 5
When a commercial building's measured air leakage exceeds 0.40 cfm/ft2 but does not exceed 0.60 cfm/ft2 under the 2021 IECC, what does the code require?
Automatic failure and complete air barrier replacement
A diagnostic evaluation using smoke tracer or infrared imaging while pressurized, plus a visual inspection, sealing any leaks found
No further action because it is within an acceptable buffer
Re-testing at a lower pressure of 50 Pa
