IEQ assessment
Indoor Air Quality Assessment
A structured indoor air quality assessment gives you defensible evidence of what occupants are actually breathing — and a prioritised plan to fix what matters first.
- CO₂, PM2.5, TVOCs, formaldehyde, temperature, humidity
- Calibrated sensors with 1-minute resolution
- CIBSE TM40, WELL v2 and BREEAM Hea 02 benchmarks
- Floor-by-floor heatmaps and trend charts
- Chartered written report with costed actions
- Optional occupant comfort survey
What an IAQ assessment covers
An indoor air quality assessment measures the pollutants and conditions most strongly linked to occupant health, cognition and comfort: carbon dioxide as a proxy for ventilation effectiveness, fine particulates (PM2.5) from outdoor air and indoor sources, total VOCs and formaldehyde from finishes and furnishings, and the thermal envelope of temperature and relative humidity.
Measurements are taken across a representative sample of workspaces over a one- to four-week monitoring window so the data reflects real occupancy patterns rather than a single spot check.
Who this is for
Our assessments are commissioned by facility managers, property managers, HR and wellbeing leads, health & safety teams, workplace consultants and building owners who need credible IAQ data for occupant briefings, lease negotiations, refurbishment scoping, or WELL and BREEAM evidence packs.
Our assessment process
1. Scoping call to confirm objectives, building geometry and sample size. 2. Pre-deployment HVAC walk-through. 3. Continuous monitoring across representative zones. 4. Data analysis against published benchmarks. 5. Written report with prioritised, costed recommendations. 6. Optional debrief with your facilities and wellbeing teams.
What you receive
A signed report covering compliance position, root-cause analysis of any exceedances, and a 30/90/365-day action plan separating quick BMS-level wins from capital interventions. All raw data is delivered alongside the report so you retain a defensible audit trail.
Frequently asked questions
- How long does an assessment take?
- Typically 2–4 weeks of monitoring plus one week for analysis and reporting.
- Do we need to vacate the building?
- No. Measurements are non-intrusive and produce more representative data when taken during normal occupancy.
- Will the report stand up for WELL or BREEAM evidence?
- Yes. Reports are written to be portable into WELL v2 Air concept and BREEAM Hea 02 evidence packs.
