Indoor air monitoring for offices
Office indoor air quality directly influences cognitive performance, complaint volumes and occupancy decisions. We monitor the parameters that actually matter for workplace wellbeing and ventilation operation — not vanity dashboards.
Office monitoring
The core parameter set
A typical office programme combines continuous sensors with periodic deep-dive testing. The four parameters below resolve most ventilation and comfort issues.
< 1000 ppm
Ventilation indicator in occupied zones.
< 15 µg/m³
Filter and infiltration performance.
< 500 µg/m³
Materials, cleaning and refurb impact.
20–24 °C · 40–60 % RH
Operative temperature and humidity.
Workplace wellbeing evidence
Continuous datasets quantify ventilation performance against BS EN 16798-1 and CIBSE TM40 — useful for ESG, WELL and tenant negotiations.
Complaint investigations
Targeted deployments around reported headaches, stuffiness or odours separate ventilation issues from chemistry issues from comfort drift.
Ventilation operation review
Cross-reference sensor data with BMS schedules to confirm AHUs, VAVs and demand-controlled ventilation actually deliver in occupied hours.
Refurbishment check
Pre- and post-occupancy snapshots after fit-outs surface VOC and formaldehyde drift from new finishes, furniture and adhesives.
When to commission
When offices commission monitoring
Tenant complaints about stuffiness or fatigue, new fit-outs and refurbishments, lease negotiation, ESG and wellbeing reporting, or as part of a building-management baseline.
Often paired with office ventilation monitoring, workplace environmental monitoring and long-term programmes.
Benchmarks
Reference values used for office reporting
| Parameter | Reference value | Source |
|---|---|---|
| CO₂ (occupied) | < 1000 ppm typical, 800 ppm above outdoor (Cat II) | BS EN 16798-1 |
| PM2.5 (24-h) | < 15 µg/m³ | WHO 2021 |
| PM10 (24-h) | < 45 µg/m³ | WHO 2021 |
| TVOC | < 500 µg/m³ | WELL v2 Air |
| Operative temperature | 20–24 °C heating / 23–26 °C cooling | CIBSE Guide A |
| Relative humidity | 40–60 % | ASHRAE 55 / WELL v2 |
