HVAC air quality monitoring
HVAC air quality monitoring for commercial buildings
Make your HVAC system observable. Inline duct, AHU and return-air sensors stream live data on filtration efficiency, fresh-air rates, CO₂, PM and humidity — feeding BMS controls and FM dashboards.
Why monitor
The HVAC metrics we instrument
HVAC systems consume around 40% of commercial building energy and govern almost every air-quality outcome occupants experience. Monitoring closes the loop between design intent and delivered performance.
≥10 L/s·p
BS EN 16798 Cat II per occupant.
ePM1 ≥50%
WELL / BREEAM target for offices.
<250 Pa
Beyond this, replace filter stage.
<1000 ppm
Drives demand-controlled ventilation.
Inline duct sensors
CO₂, PM2.5, VOC and RH probes mounted in supply and return ducts.
BMS / BACnet integration
Sensor data streams to BMS for demand-controlled ventilation strategies.
Filter verification
Pre/post-filter differential pressure and PM ratios confirm filtration class.
Energy optimisation
Right-size fresh-air delivery to occupancy without sacrificing IAQ.
Use cases
Where HVAC air quality monitoring earns its keep
New AHU commissioning, post-retrofit verification, healthy-building certification, complaint investigations, and any portfolio targeting net-zero where fresh-air delivery has to be evidence-based rather than assumed.
Pair with indoor air quality monitoring, continuous air quality monitoring and CO₂ monitoring.
Benchmarks
HVAC reference standards we report against
