14. Air infiltration management
To minimize air quality and thermal comfort issues resulting from the infiltration of untreated air through the building envelope.
Indoor 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 growth of molds and the infiltration of pests or polluted air.
The following is performed after substantial completion and prior to occupancy to ensure the structure is airtight:
One of the following methods is used to evaluate the building envelope:
