Indoor Air Quality Monitoring India | NABL Accredited

Auriga Research provides NABL-accredited indoor air quality (IAQ) monitoring for offices, factories, hospitals, data centres, and commercial buildings across India. Our IAQ assessments measure CO2, TVOC, formaldehyde, PM2.5, PM10, CO, temperature, humidity, and airborne microbial counts per ISHRAE 10001, NBC 2016, and ASHRAE 62.1 guidelines.

Poor indoor air quality directly impacts occupant health, productivity, and regulatory compliance. Our monitoring identifies ventilation deficiencies, chemical off-gassing sources, and microbial contamination — providing actionable data for HVAC optimisation and green building certification requirements.

IAQ Monitoring Parameters

CO2 — ventilation adequacy indicator (NDIR method)
TVOC — total volatile organic compounds (PID method)
Formaldehyde (HCHO) — DNPH cartridge with HPLC analysis
PM2.5 and PM10 — laser particle counter
CO — electrochemical sensor
Temperature and relative humidity
Airborne microbial counts — total bacteria and fungi (impaction method)
Ozone (O3) and NO2 — for photocopier/printer zones
Radon — for basement and ground-floor assessments

Who Needs IAQ Monitoring

Green building projects pursuing IGBC, GRIHA, or LEED certification
Corporate offices conducting occupant wellness assessments
Hospitals and cleanrooms verifying air handling performance
Industrial workplaces complying with Factories Act exposure limits
Data centres and server rooms monitoring air quality

Turnaround Time

On-site IAQ monitoring for a single floor or zone takes 1-2 days. Microbial sample incubation requires 5-7 days. Complete IAQ assessment reports are delivered within 10-12 business days of field monitoring.

Frequently Asked Questions

What parameters are measured in indoor air quality testing?

Indoor air quality testing covers CO2, CO, temperature, relative humidity, PM2.5, PM10, TVOC (total volatile organic compounds), formaldehyde, ozone, NO2, and airborne microbial counts (total bacterial and fungal colony counts). For industrial workplaces, we additionally monitor specific chemical exposures per the Factories Act and OSHA/ACGIH TLV guidelines.

What standards govern indoor air quality in India?

ISHRAE Standard 10001 provides indoor environmental quality guidelines for Indian conditions. The National Building Code (NBC 2016) specifies ventilation and IAQ requirements. For industrial workplaces, the Factories Act 1948 and DGFASLI guidelines specify permissible exposure limits. GRIHA and IGBC green building certifications also mandate IAQ monitoring against ASHRAE 62.1 ventilation standards.

How often should indoor air quality be monitored?

Green building certifications (IGBC, GRIHA, LEED) typically require IAQ testing during commissioning and annually thereafter. Industrial workplaces should monitor occupational air quality quarterly or semi-annually depending on hazard classification. Commercial offices and hospitals benefit from annual IAQ audits to verify HVAC performance and occupant comfort conditions.
