About This Standard

ISO 16000-40 specifies management system requirements for indoor air quality (IAQ) in non-industrial buildings including offices, schools, retail premises, and public buildings. It provides a framework for monitoring, measuring, and improving air quality to protect building occupants from chemical pollutants, biological agents, and particulate matter.

The standard addresses the growing concern about the health impacts of poor indoor air quality, which can include volatile organic compounds (VOCs), CO2, particulates, humidity, and biological contaminants. It establishes systematic management requirements rather than prescribing specific measurement techniques.

ACI-certified auditors assess IAQ management systems and evaluate the effectiveness of monitoring, communication, and improvement processes in real estate and facilities management contexts.
