Indoor air quality and workplace wellbeing: the business case
Indoor air quality affects productivity, absence and staff retention. Here's why more Irish employers are measuring it — and what a good IAQ survey covers.
Niamh O'Brien Air Quality & Occupational Hygiene SpecialistWe spend around 90% of our time indoors, yet indoor air quality (IAQ) is often an afterthought — until people start complaining of headaches, stuffiness or fatigue. For employers, the return on getting it right is measurable.
Why IAQ is climbing the agenda
- Productivity. Studies consistently link elevated CO₂ and poor ventilation with reduced cognitive performance.
- Absence and wellbeing. Stuffy, poorly ventilated spaces contribute to the vague-but-real “sick building” effect.
- Post-pandemic expectations. Ventilation is now something staff, unions and facilities teams actively ask about.
What a good IAQ survey measures
A meaningful indoor air quality assessment goes well beyond temperature:
| Parameter | Why it matters |
|---|---|
| CO₂ | A proxy for ventilation adequacy and occupancy |
| PM2.5 / PM10 | Fine particulates from outdoor air and activities |
| VOCs | Off-gassing from furnishings, cleaning, printing |
| Temperature & humidity | Comfort, and mould/condensation risk |
| CO | Combustion safety where relevant |
Reading the results
The value is in interpretation. A CO₂ reading spiking each afternoon points to under-ventilation at peak occupancy. Elevated VOCs after a refurbishment suggest off-gassing that will settle — or a source that needs removing. A good report tells you not just the numbers, but what to do about them.
Practical, low-cost wins
Many IAQ issues resolve without major capital spend:
- Commission or rebalance existing ventilation
- Adjust fresh-air rates for actual occupancy
- Review cleaning products and printing locations
- Add localised extraction where needed
