Indoor environmental quality
Indoor Environmental Assessment
An indoor environmental quality (IEQ) assessment looks beyond air alone — it characterises the four factors that shape occupant experience: air, thermal, light and sound.
- IAQ baseline (CO₂, PM, VOC)
- Thermal comfort (PMV/PPD)
- Daylight & lux levels
- Acoustic environment
- Occupant survey
- Integrated IEQ scorecard
The four IEQ pillars
Air, thermal, light and acoustic conditions are usually surveyed in silos by different specialists. We deliver them as one integrated assessment because occupants experience them as one environment.
Who this is for
Facility managers, property managers, HR and wellbeing leads, health & safety teams, workplace consultants and building owners commissioning a major refurbishment, pursuing WELL or BREEAM, or responding to broad-based occupant dissatisfaction.
Deliverables
Integrated IEQ scorecard, per-pillar deep-dive sections, prioritised action plan, and a clear translation layer between technical findings and HR/occupant communications.
Frequently asked questions
- Do you use external specialists?
- We lead the assessment and bring in accredited acoustic and lighting partners where required.
- How does this compare to a WELL pre-assessment?
- An IEQ assessment is broader than WELL Air but lighter than a full WELL gap analysis — it's a useful first step.
- How long does it take?
- Typically 4–6 weeks end-to-end.
