Indoor air quality is primarily concerned with what?

Indoor air quality focuses on the measure of air health inside buildings because it directly impacts the well-being and health of occupants. This quality is assessed by analyzing various factors, including the presence of pollutants, humidity levels, and the adequacy of ventilation. Good indoor air quality is associated with lower levels of allergens, toxins, and harmful substances, contributing to better respiratory health and overall comfort for individuals within the space.

While energy usage in buildings, temperature control, and external air pollution levels can influence indoor air quality, they are not the primary concern when it comes to assessing how well the indoor environment supports the health of its inhabitants. For instance, adequate temperature control and energy efficiency can enhance comfort and reduce energy costs, but they do not specifically measure or ensure air health. Similarly, external air pollution can affect indoor conditions but does not define the quality of air within the building itself. Therefore, the focus on air health is what distinguishes indoor air quality as a critical aspect of building environments.
