Stuffy meeting rooms aren't a comfort issue — they're a productivity tax. A practical look at IAQ for the post-pandemic workplace.
Cognitive performance falls measurably above 1,000 ppm CO₂. Most meeting rooms exceed that within twenty minutes of being occupied. The post-pandemic conversation around indoor air quality has moved from 'nice to have' to a hard productivity metric.
The four levers that actually matter 1. **Outdoor air rate** — design to CIBSE Guide A minimums and verify with airflow testing. 2. **Filtration** — ISO 16890 ePM1 ≥ 50% as a baseline for offices in urban areas. 3. **Humidity** — keep RH between 40–60% for comfort and to suppress aerosol viability. 4. **Monitoring** — CO₂ as a proxy is cheap, visible and changes occupant behaviour.
What we typically deliver An IAQ baseline survey, filter upgrade plan, an MVHR or AHU service uplift, and live CO₂ monitoring in the spaces that matter most. The result is fewer afternoon-slump meetings — and far fewer complaints in the FM inbox.
