Which parameters actually matter

CO2 is the workhorse: it tracks how well ventilation keeps up with people, and it is the metric HSE’s workplace ventilation guidance leans on. Temperature and humidity are the comfort pair — most complaints live in their interaction, not in either number alone. TVOC catches off-gassing after fit-outs and cleaning regimes gone wrong; particulates matter near busy roads or workshops.

Spend where people concentrate: meeting rooms fail first because ventilation was designed for four people and the room hosts ten. A sensible rollout is CO2-class sensors in every enclosed meeting space, mid-tier units per open-plan zone, and cheap temperature/humidity everywhere else. That pattern gives complete office air quality monitoring coverage at roughly half the cost of uniform top-tier hardware.

• Meeting rooms: alert at 1000 ppm CO2, act at 1500 ppm
• Comfort band: 21–24 °C and 40–60 % RH covers most UK offices
• TVOC spikes after fit-out or new furniture are worth a look, not a panic
• PIR-equipped models add occupancy context — was the room even in use?
• Battery sensors relocate freely when floors are re-planned
• History defends the FM team when the complaint reaches the board
