Baseline Air Quality Survey
Trusted since 1999 · Proven delivery partner
A baseline air quality survey establishes the reference conditions for your building — providing the benchmark against which all future measurements are compared. Green Air Monitoring delivers baseline surveys that create the foundation for ongoing IAQ management, trend analysis, and compliance evidence.
What a Baseline Survey Establishes
The baseline survey captures your building's IAQ profile under normal operating conditions, creating a documented reference point.
- CO₂ concentration profiles across occupied zones
- VOC and formaldehyde levels from furnishings and finishes
- PM2.5 and PM10 particulate concentrations
- Temperature and humidity patterns
- Ventilation adequacy assessment
- Identification of any existing issues requiring attention
When to Commission a Baseline
Baseline surveys are most valuable at the start of a new tenancy or lease, following building handover from construction or refurbishment, when establishing a new IAQ monitoring programme, before or after significant fit-out changes, and when taking over FM responsibility for a building.
Building on the Baseline
Once established, the baseline enables meaningful trend analysis at subsequent surveys. Deterioration from baseline triggers investigation and remediation before complaints arise. Improvement from baseline demonstrates the value of your maintenance and ventilation management programmes.
