Indoor Air Quality Monitoring
CO₂, temperature, humidity, particulates, and VOC assessment for occupied buildings
What Is Indoor Air Quality Monitoring?
Indoor air quality (IAQ) monitoring assesses the physical, chemical, and biological parameters that affect occupant comfort and health in non-industrial buildings — offices, schools, hospitals, and retail spaces. Parameters include CO₂, temperature, relative humidity, airborne particulates, VOCs, and mould.
While CO₂ above 800 ppm indicates inadequate ventilation, the WES of 5,000 ppm is an occupational limit. IAQ investigations typically reference ASHRAE 62.1 and the AIOH IAQ Position Paper for ventilation rates and comfort parameters.
How Is It Done?
Direct-reading instruments for CO₂, temperature, humidity, and PM2.5/PM10. VOC screening via PID. Mould sampling (spore trap or swab) where bioaerosol concerns exist.
