In many countries, the use of hazardous materials such as Volatile Organic Compounds (VOCs) and lead in paints has been restricted due to their potential negative health impacts. VOCs can significantly affect respiratory health and may increase cancer risks, while lead is known for its toxicity and potential to cause serious health issues. Therefore, minimizing the use of these substances in paints aligns with the WELL Materials concept, which encourages the use of products tested for low VOC emissions and free of harmful ingredients like lead​​.

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.

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.
