What is Indoor Air Quality (IAQ)?

Indoor Air Quality (IAQ is a term used to characterize health and comfort-related conditions inside a building designed for human occupancy. Relevant factors include air temperature, relative humidity levels, airborne and surface contaminant concentrations, lighting, and noise. A building\’s IAQ is typically considered acceptable if occupants are not exposed to harmful contaminant concentrations and a large majority of the occupants are satisfied with Indoor Air conditions. Occupants\’ perceptions of IAQ for a building, or a space within a building, can vary because of individual variations in temperature/humidity level preferences and sensitivities to chemical and biological contaminants. Perceptions can also be affected by issues that are not associated with Indoor Air conditions, such as unrelated health problems and psychosocial factors (work-related or personal stress).
