Answer: C

Explanation:

A building owner should use an air tightness test to assess the building envelope’s performance in regard to moisture protection. An air tightness test measures the rate of air leakage through the building envelope, which can indicate the potential for moisture infiltration and condensation. Moisture can enter buildings and building assemblies in four ways: bulk water, capillary water, air-transported moisture and vapor diffusion. Air-transported moisture is the most significant source of moisture problems in buildings, as it can carry large amounts of water vapor through small openings and gaps in the envelope. By conducting an air tightness test, the building owner can identify and seal any air leaks that could compromise the moisture protection of the building envelope.
