From the 2021 IECC:
Exception: When testing individual dwelling
units, an air leakage rate not exceeding
0.30 cubic feet per minute per square
foot [0.008 m3/(s x m2)] of the dwelling unit
enclosure area, tested in accordance with
ANSI/RESNET/ICC 380, ASTM E779 or
ASTM E1827 and reported at a pressure of
0.2 inch w.g. (50 Pa), shall be permitted in
all climate zones for:
1. Attached single and multiple- family
building dwelling units.
2. Buildings or dwelling units that are
1,500 square feet (139.4 m2) or smaller.
Results:
1,001 CFM/ 5,394 Sq Ft Surface
Area = .19 CFM/Sq Ft.
I I Building Passes.
From the 2018 IECC: R402.4.1.2 Testing.
The building or dwelling unit shall be tested
and verified as having an air leakage rate
not exceeding (3.00 ACH50) three air
changes per hour in Climate Zones 3
through 8. Testing shall be conducted in
accordance with RESNET/ICC 380, ASTM
E779 or ASTM E1827 and reported at a
pressure of 0.2 inch 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.
Building is at 3.44 ACH50.
