Indoor Air Quality (IAQ) is a measure of the cleanliness and safety of the air inside buildings, influenced by various factors such as pollutants, ventilation effectiveness, temperature, and humidity. In workplaces, maintaining good IAQ is essential for occupant comfort, productivity, and health. Mould growth is one of the most common IAQ concerns, as mould spores and microbial volatile organic compounds (MVOCs) can accumulate in poorly ventilated or damp spaces, leading to allergic reactions, respiratory distress, and other health complaints among employees.
Beyond mould, IAQ can be compromised by factors like chemicals off-gassing from building materials, carbon dioxide buildup from inadequate ventilation, or dust and particulate matter from industrial processes. Regular assessments of IAQ often involve measuring pollutant concentrations, checking humidity levels, and ensuring that mechanical ventilation systems meet established standards (such as AS 1668.2).
Improving IAQ typically involves a holistic approach. Employers might install high-efficiency filters in HVAC systems to reduce airborne particles, use dehumidifiers or air conditioners to control moisture, and enforce “no-smoking” policies or limit the use of chemical cleaners. Proper housekeeping measures, regular maintenance of HVAC systems, and immediate repair of any water leaks are also critical. By prioritizing IAQ, workplaces can provide a safer, healthier environment that ultimately benefits employee morale and reduces health-related expenses.
