Indoor Air Quality Standards are air quality guidelines that establish minimum acceptable concentrations of indoor air pollutants commonly found in indoor air environments. These standards set limits on the concentration of specific pollutants such as volatile organic compounds, particulate matter, carbon monoxide, and lead. Indoor air quality standards are used by businesses, public health organizations, and governments to help promote the health of workers, occupants, and visitors to indoor air environments. They are especially important in the context of “sick building syndrome” where occupants experience symptoms due to prolonged exposure to indoor air pollutants.
Indoor air quality standards also have an impact on energy efficiency and building design. Poor indoor air can lead to higher energy costs due to inefficient HVAC systems, as well as higher maintenance costs due to reduced equipment life. When designing an indoor air space, experts are able to account for indoor air quality standards by assessing ventilation and filtration systems. The goal of these systems is to maintain indoor air quality by trapping and removing airborne pollutants, while ensuring ample fresh air supply. Without proper consideration of indoor air quality standards, occupants would be exposed to potentially dangerous levels of pollutants.
