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.

High levels of carbon monoxide (CO) and nitrogen dioxide (NO2) indoors typically indicate the presence of combustion sources. These gases are common byproducts of combustion processes, such as those from burning fuels in vehicles, stoves, lanterns, and furnaces, or when wood or gas is burned. Effective ventilation, maintenance of combustion appliances, and proper building envelope design are critical to preventing the accumulation of these gases in indoor environments, as outlined in WELL standards for maintaining optimal air quality.

Feature A11: Source Separation mandates that spaces with high pollution potential, like copy rooms, have their air exhausted directly outside to prevent indoor air quality deterioration. Copy rooms often house equipment like photocopiers and printers, which can emit volatile organic compounds (VOCs), particulate matter, and ozone, contributing to indoor air pollution. By ensuring that air from these spaces is expelled rather than recirculated, the strategy minimizes the spread of pollutants throughout the building, safeguarding occupant health and aligning with the WELL Standard's emphasis on optimal indoor air quality.
