Office Indoor Air Quality
Good office indoor air quality is non-negotiable for modern employers. It is also straightforward to measure and surprisingly tractable to improve.
- CO₂ under 800 ppm during occupancy
- PM2.5 under 12 µg/m³
- TVOCs under 300 µg/m³
- RH 40–60%
- Temperature 21–24 °C
- Continuous monitoring in place
What good looks like
A modern, well-run UK office should hold the targets above through normal occupancy hours, with no sustained exceedances and a visible monitoring story for occupants.
