According to USACE 2012, what is the maximum baseline pressure?

The maximum baseline pressure according to USACE 2012 guidelines is established as less than 30% of the minimum induced pressure difference. This specification is crucial in whole-building airtightness testing to ensure that measurements taken during testing remain within a defined and reliable range.

A baseline pressure that is set according to these guidelines helps maintain consistency in the testing conditions, enabling accurate comparisons of results across different tests. This percentage serves to ensure that the conditions under which the testing is conducted do not significantly skew the results, providing a more meaningful evaluation of the building's airtightness performance.

By adhering to this standard, testers can effectively manage potential variables and ensure that the results reflect the actual performance of the building envelope without the interference of excess pressure which could affect the outcome of the air leakage measurements.
