Indoor Environmental Monitoring — Measuring Indoor Environmental Quality

Occupant complaints rarely arise from a single pollutant. Hot, stuffy meeting rooms feel uncomfortable long before CO₂ breaches any guideline. Low humidity in winter triggers dry-eye complaints that get blamed on "the air conditioning". Measuring the full environmental picture lets the report explain what people are actually experiencing, not just what one sensor happened to record.

Frameworks like WELL v2, BREEAM Hea 02 and RESET Air explicitly require multi-parameter monitoring — a single CO₂ trace will not satisfy any of them.

Sensor positions are chosen by zone use and ventilation topology, not by convenience. Wall-mounted breathing-zone sensors sit between 1.1 m and 1.5 m above floor level, away from supply diffusers, windows and direct sunlight. Networks are LoRaWAN or secure Wi-Fi; data flows into a dashboard with role-based access for facilities, HR and senior leadership.

Where existing BMS or building analytics platforms are in place, we integrate via BACnet/IP or REST so a single pane of glass shows IEQ alongside energy and occupancy. For a sensor-led starting point, see our indoor air monitoring systems page.
