IAQ Monitoring for BREEAM, WELL & LEED Certification

The Challenge:
Building owners and developers pursuing BREEAM, WELL, or LEED certification must demonstrate compliance with stringent indoor air quality (IAQ) standards to ensure healthy, sustainable, and occupant-friendly environments. Meeting these requirements involves:

Developing an Indoor Air Quality Plan (as required by BREEAM and LEED) early in the design stage to mitigate sources of indoor pollution.
Pre- and post-occupancy testing for critical pollutants such as VOCs, formaldehyde, particulate matter (PM_2.5/PM₁₀), CO₂, CO, ozone, and NO₂.
Adherence to strict pollutant thresholds, such as:
- WELL PM_2.5 limit: ≤15 µg/m³
- LEED TVOC limit: ≤500 µg/m³
- BREEAM thresholds aligned with WHO indoor air quality guidelines.
Accredited lab analysis and comprehensive documentation to support audit readiness and achieve credit under:
- BREEAM
- WELL Features
- LEED EQ credits (IAQ Assessment, Construction IAQ Management Plan)

Failure to meet these requirements can result in certification delays, increased costs, and compromised sustainability goals.

How We Help:
At IEQCheck, we specialise in end-to-end IAQ monitoring and compliance support tailored to the unique requirements of BREEAM, WELL, and LEED.

Comprehensive Air Quality Strategy

IAQ Plan Development: Early-stage planning to minimise pollutant sources from materials, HVAC systems, and construction activities—meeting BREEAM and LEED prerequisites.
Pre-Occupancy Testing
- For BREEAM/LEED: Conducted in representative areas for TVOCs, formaldehyde, PM_2.5, PM₁₀, CO, CO₂, NO₂, ozone, and radon (region-specific).
- Data evaluated against LEED Option 1 thresholds, BREEAM Hea 02 targets, and WHO guidelines.
Post-Occupancy Testing

For WELL: Carried out under Feature X05 to ensure ongoing compliance once the building is in use.

Accredited Analysis and Documentation

All testing conducted by UKAS (ISO 17025) accredited laboratories to meet certification body standards.
Compliance with WELL v2 thresholds, ASHRAE 62.1, and WHO IAQ guidelines.
Full reports mapped directly to BREEAM Hea 02, WELL Features X05/X06, and LEED EQc3 requirements.
