IAQ surveys and LEV validation for healthy, productive workplaces
Indoor air quality assessments evaluate the full spectrum of contaminants — VOCs, particulates, CO/CO2, biological agents — and verify ventilation effectiveness. We benchmark conditions against WHO, ASHRAE, and ACGIH guidance and design ventilation upgrades aligned to ISO 16000.
A practical, phased delivery approach — from gap assessment through operational embedding — built around your regulatory context.
Investigate IAQ complaints per AIHA / NIOSH / EPA BAQ / WHO IAQ — symptom survey, occupant interview, walkthrough; establish baseline measurement plan per ASHRAE 62.1 / EN 13779.
Measure IAQ parameters — CO₂ (proxy for ventilation), CO, PM2.5 / PM10, total VOC (PID), formaldehyde, radon, mould (viable / total spore count), temperature, humidity; align with ASHRAE 62.1 / EU EN 16798.
Evaluate HVAC per ASHRAE Standard 62.1 — outdoor air supply rate (cfm per person), filtration (MERV rating), economiser operation, controls, condensate management, maintenance frequency; align with LEED IEQ credits.
Design source control — VOC source removal (low-emission materials per LEED / EU GreenBuilding), mould remediation (IICRC S520), CO source elimination (gas appliance), radon mitigation (sub-slab depressurisation per EPA 625).
Design ventilation upgrade per ASHRAE 62.1 / 62.2 — increase outdoor air, demand-controlled ventilation per CO₂, MERV-13+ filtration, UVGI (ultraviolet germicidal irradiation) where applicable per ASHRAE 185.
Implement IAQ continuous monitoring (CO₂, PM, VOC) per LEED OM / WELL Building Standard; specify monthly review and corrective action workflow; align with HVAC commissioning and continuous commissioning.
