Definition

Indoor Environmental Quality (IEQ) is a broader and more comprehensive concept than indoor air quality (IAQ). It encompasses various aspects of the indoor environment within buildings or enclosed spaces, focusing on how these elements collectively impact the comfort, health, and overall well-being of occupants. IEQ factors include indoor air quality (IAQ) but also extend to considerations such as thermal comfort, lighting, acoustics, ergonomic conditions, and the overall psychological and social aspects of the indoor environment.

IEQ takes into account not only the absence of pollutants and the quality of indoor air but also the overall physical and psychological aspects that contribute to a safe, comfortable, and productive indoor setting. Achieving good IEQ involves creating spaces that encourage health, comfort, and productivity while considering a range of environmental factors that extend beyond air quality.
