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.

CO₂

< 1000 ppm

Ventilation indicator in occupied zones.

PM2.5

< 15 µg/m³

Filter and infiltration performance.

TVOC

< 500 µg/m³

Materials, cleaning and refurb impact.

Comfort

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.
