Air infiltration management
14. Air infiltration management
Building's air quality and thermal comfort can be compromised by leaks and gaps that break the building's air barrier. These weak points are not only wasteful, but can also lead to conditions conducive to mold growth and the infiltration of pests or polluted air.
This feature is a performance test to check for air leakages in the building envelope. Such tests are often used to optimize a building's energy efficiency and can also be used to maintain indoor air quality and comfort.
The following requirement is met:
One of the following methods is used to evaluate the building envelope:
