Which testing method is not included in the USACE 2012 standards?

The method of testing that is not included in the USACE 2012 standards is repeatable multi-point testing. This approach is not part of the recognized standards and guidelines established by the U.S. Army Corps of Engineers, which focus on methods that can be more consistently applied within the scope of building airtightness testing.

The other methods—multi-point testing, single-point testing, and two-point testing—are specified within the USACE 2012 standards, providing defined protocols for assessing airtightness in buildings. Multi-point testing allows for multiple pressure differences to be measured, giving a more comprehensive understanding of a building's leakage characteristics. Single-point testing establishes a pressure difference at one point in time, while two-point testing measures the building's performance at two designated pressure points. These methodologies are standard practices in the field, ensuring that testing is both reliable and comparable across different evaluations.
