Air infiltration management

Air infiltration management

Intent: 

To minimize air quality and thermal comfort issues resulting from the infiltration of untreated air through the building envelope.

There is no preferred air leakage testing standard that inherently meets this feature requirement. The testing methods used to achieve Part 2 are generally at the discretion of the envelope commissioning agent, as outlined in the NIBS and ASHRAE guidelines. Documentation submitted to meet Part 2 (Air leakage test results and contractor LoA) must demonstrate alignment between the chosen leakage test results and the test method recommended by the envelope commissioning agent in the envelope commissioning report submitted to meet Part 1.
