CO2 levels above 1,000 ppm are associated with reduced cognitive performance and increased occupant complaints. Elevated particulate matter, humidity variance, and VOC levels all contribute to poor indoor environment quality (IEQ). For facility managers, documented indoor air quality testing and monitoring in Brisbane commercial facilities also supports Workplace Health and Safety Queensland compliance obligations and demonstrates proactive building management.

QPT installs CO2 sensors in commercial environments including offices, meeting rooms, classrooms, retail spaces, and hospitality venues. Sensor placement follows ASHRAE and NCC guidance to produce meaningful measurements. We also test and calibrate existing CO2 sensors: NDIR sensors drift over time and must be periodically calibrated to remain accurate.

Beyond CO2, comprehensive IAQ monitoring in Brisbane commercial buildings covers temperature, relative humidity, PM2.5, PM10, VOCs, and TVOC levels. QPT installs monitoring systems that provide real-time data, trending, and alerting to support proactive facility management.

CO2 monitoring can identify ventilation deficiencies that commissioning reports missed in practice. Where elevated CO2 points to inadequate fresh air supply, QPT’s combined electrical and mechanical capability means we can work with your HVAC team to address root causes within the same contractor relationship.
