Ensure a safe, complaiance building in IAQ sensors

Indoor Air Quality (IAQ) has become a core component of modern sustainability frameworks. Standards such as BREEAM, LEED, WELL, Fitwel, and B-Corp all recognise IAQ as essential to environmental health and occupant wellbeing, often requiring or recommending evidence-based strategies to meet performance criteria and earn credits. Whether through minimum air quality thresholds, post-occupancy testing, or continuous monitoring requirements, IAQ is now central to achieving valuable credits and demonstrating long-term building performance.

The Role of Real-Time IAQ Monitoring

One of the most effective ways to meet these expectations is through real-time indoor air quality sensors. By continuously tracking key pollutants such as CO₂, PM2.5, VOCs, and formaldehyde, these devices provide ongoing insight into indoor environmental conditions. This data supports compliance, enables proactive air quality management, and helps maintain healthier, more sustainable buildings.

How IAQ Supports Leading Certification Schemes

BREEAM

BREEAM places strong emphasis on IAQ through credits such as Hea 02 Indoor Air Quality, encouraging both upfront planning and long-term monitoring. Projects must assess IAQ risks, implement measures to reduce pollutant exposure, and demonstrate ongoing performance.

Continuous IAQ monitoring strengthens evidence for post-occupancy performance, supporting compliance with BREEAM’s rigorous, data-led requirements.

LEED

LEED incorporates IAQ within its Indoor Environmental Quality (EQ) category. Credits are available for Enhanced IAQ Strategies and Indoor Air Quality Assessments, which may involve pollutant flush-outs or post-construction testing. Using real-time IAQ sensors provides reliable proof of consistent air quality over time—helping teams document long-term compliance and secure valuable LEED credits.

WELL Building Standard

The WELL Standard places IAQ at the heart of its health-first approach. Features such as A01 (Fundamental Air Quality), A03 (Enhanced Air Quality), and A05 (Air Quality Monitoring and Awareness) depend directly on measuring airborne pollutants. WELL-certified buildings must meet strict contaminant thresholds and are actively encouraged—or required—to provide live IAQ data to occupants. Continuous monitoring is essential to meeting WELL’s transparency and performance criteria.

Fitwel Certification

Fitwel includes IAQ within its broader focus on workplace wellbeing. While less prescriptive than WELL, Fitwel rewards organisations that can demonstrate reduced exposure to pollutants through data-backed interventions. Continuous monitoring provides credible evidence of building performance under real-world conditions, strengthening Fitwel submissions.

The Value of Continuous IAQ Monitoring

Traditional IAQ assessments capture only a snapshot in time, missing fluctuations caused by occupancy patterns, ventilation rates, building usage and seasonal changes. Continuous IAQ monitoring gives organisations a complete, real-time understanding of environmental performance.

Improving Workplace Ventilation & Air Quality
Improving Workplace Ventilation & Air Quality

2023-07-01

The law says employers must make sure there’s an adequate supply of fresh air in the workplace. There are two ways of maximising the level of fresh air in a workspace, either by natural and / or mechanical ventilation. Ventilation control measures play an essential role in improving air quality and staff well being.
