Indoor Air Quality (IAQ) Monitoring

Indoor air quality directly affects occupant health, productivity, and — for regulated environments — product safety. Auriga Research provides NABL-accredited indoor air quality (IAQ) monitoring for offices, factories, hospitals, cleanrooms, data centres, and commercial buildings across India, measuring CO₂, TVOC, formaldehyde, PM2.5, microbial counts, and comfort parameters from our Bahadurgarh Environmental & Industrial Monitoring Laboratory.

IAQ monitoring is not universally mandatory in India — but it is required for LEED / IGBC / GRIHA green building certification, for pharmaceutical and food cleanroom compliance under GMP and ISO 14644, and is increasingly specified in occupational health audits for factories under the Factories Act 1948. The reference guidelines are ASHRAE 62.1, ISHRAE 10001, and the draft IS 15848 — we scope testing to the driver that actually applies to you rather than over-testing.

TVOC is measured by GC-FID per ASTM D6196 / IS 13010 (with PID screening for site mapping), and formaldehyde by DNPH-HPLC. Backed by the Arbro Group's analytical heritage — Arbro Lab since 1990, Auriga Research since 2007 — with NABL ISO/IEC 17025 accreditation, reports compare measured values against the applicable ASHRAE 62.1 / ISHRAE 10001 / IS 15848 or ISO 14644 benchmark and are accepted by green-building assessors, occupational-health auditors, and cleanroom validation teams.

On-site monitoring 1–2 days | Report in 10–12 working days (microbial incubation 5–7 days)

IAQ Monitoring Parameters

Each parameter is mapped to its measurement method so facility, EHS, and certification teams can match scope to the ASHRAE 62.1 / ISO 14644 benchmark at a glance.

CO₂

Ventilation Indicator

Carbon dioxide by NDIR — the primary indicator of ventilation adequacy and fresh-air supply.

TVOC

Total Volatile Organics

Total VOCs by GC-FID per ASTM D6196 / IS 13010, with PID screening for real-time mapping of off-gassing sources.

HCHO

How It Works

Get a Quote & Scope

Share your facility type, the zones / floor area, and the driver (green-building certification, GMP / ISO 14644 cleanroom, or an occupational health audit). Your dedicated SPOC scopes the parameters, the applicable benchmark (ASHRAE 62.1 / ISHRAE 10001 / IS 15848 or ISO 14644), and the on-site schedule before the visit.

On-Site Monitoring

The Bahadurgarh lab team monitors at your premises with calibrated instruments — CO₂, CO, PM, T/RH, ozone, NO₂, and radon on-site, with TVOC sorbent tubes, DNPH formaldehyde cartridges, and microbial impaction samples collected for lab analysis. Samples are bar coded and registered in YLIMS on return to the lab.

Lab Analysis & QA Review

TVOC is quantified by GC-FID (ASTM D6196), formaldehyde by DNPH-HPLC, and microbial samples incubated for bacterial and fungal counts at the Bahadurgarh lab (NABL TC-7710). Every result is compared against the applicable benchmark and passes a formal internal QA review and sign-off before the report is generated.

Why Auriga for IAQ Monitoring

Bahadurgarh Environmental Lab — NABL TC-7710

Auriga's primary environmental monitoring facility, with a NABL scope covering air quality parameters — on-site monitoring and lab analysis under one accreditation.

Honest, scoped regulatory guidance

IAQ is not universally mandatory in India — we scope testing to your actual driver (green-building credit, GMP / ISO 14644 cleanroom, or occupational health audit) instead of selling unnecessary panels.

TVOC by GC-FID, not just a PID number

Reported TVOC is the quantitative GC-FID result per ASTM D6196 / IS 13010 — the lab-confirmed value certifiers accept — with PID used only for real-time site mapping.

Microbiology + chemistry in one lab

Bioaerosol incubation, DNPH-HPLC formaldehyde, and GC-FID TVOC all run in-house — one consolidated IAQ report, no cross-lab handover.

Green-building & cleanroom ready

Reports formatted against ASHRAE 62.1 / ISHRAE 10001 / IS 15848 for LEED / IGBC / GRIHA, and against ISO 14644 class for pharmaceutical / food cleanroom validation.

Arbro Group analytical heritage

Established analytical heritage through the Arbro Group (Arbro Lab since 1990, Auriga Research since 2007), with NABL ISO/IEC 17025 accreditation — the audit trail facility, EHS, and QA teams look for in an IAQ partner.

Frequently Asked Questions

Is indoor air quality monitoring legally mandatory in India?

For most businesses, no — there is no single universal statutory IAQ standard for offices in India, and MoEFCC does not mandate office IAQ testing. IAQ monitoring is primarily driven by: (1) LEED / IGBC / GRIHA green building certification, which require it during commissioning and recertification; (2) pharmaceutical and food cleanroom compliance under GMP and ISO 14644; and (3) occupational health audits, which are increasingly specified for factories under the Factories Act 1948. The applicable reference guidelines are ASHRAE 62.1 (international), ISHRAE 10001 (Indian indoor environmental quality), and IS 15848 (the draft Indian IAQ guideline) — these are guidelines and certification criteria, not a blanket legal requirement. We help you scope testing to the specific driver that applies to you rather than over-testing.

Which Auriga lab performs indoor air quality monitoring?

Indoor air quality monitoring is conducted by our Bahadurgarh Environmental & Industrial Monitoring Laboratory (NABL TC-7710), Auriga's primary environmental monitoring facility, whose NABL ISO/IEC 17025:2017 scope covers air quality parameters. Trained technicians carry out the on-site monitoring at your premises, microbial and DNPH samples are returned to the lab for incubation / HPLC analysis, and the accredited report is issued from Bahadurgarh.

How is TVOC measured, and what method do you use?

Total volatile organic compounds (TVOC) are measured by gas chromatography with flame ionisation detection (GC-FID) per ASTM D6196 (or the IS 13010 equivalent) on samples collected onto sorbent tubes — this is the quantitative, lab-confirmed method suitable for certification and compliance reporting. For real-time site mapping we also use a photoionisation detector (PID) to locate off-gassing hot-spots, but the reported TVOC value is the GC-FID result. Formaldehyde is determined separately on a DNPH cartridge by HPLC, since it is poorly captured by general TVOC methods.

What parameters are measured in indoor air quality testing?

IAQ testing covers CO2, CO, temperature, relative humidity, PM2.5, PM10, TVOC (GC-FID), formaldehyde, ozone, NO2, radon (for basements / ground floors), and airborne microbial counts (total bacterial and fungal colony counts). For industrial workplaces we additionally monitor specific chemical exposures against the Factories Act and ACGIH TLV guidelines as part of an occupational health audit.

How often should indoor air quality be monitored?

It depends on the driver. Green building certifications (IGBC, GRIHA, LEED) typically require IAQ testing during commissioning and annually thereafter. Pharmaceutical and food cleanrooms monitor on the frequency set by their GMP / ISO 14644 qualification (often quarterly, with continuous monitoring of critical parameters). Industrial workplaces running occupational health audits typically test quarterly or semi-annually by hazard classification. Commercial offices and hospitals benefit from an annual IAQ audit to verify HVAC performance and occupant comfort.

How does IAQ monitoring support pharmaceutical / food cleanroom compliance?

For pharmaceutical and food cleanrooms, IAQ monitoring supports GMP and ISO 14644 cleanliness classification — airborne particulate counts (by ISO 14644 class), microbial bioaerosol counts (settle plates / active air sampling), temperature, relative humidity, and differential-pressure context. This is distinct from office IAQ: the acceptance criteria come from the cleanroom's qualified class and the product's GMP requirement. Auriga reports the data against the applicable ISO 14644 class and the facility's qualification limits, formatted for the validation / requalification file.

Are Auriga IAQ reports accepted for green building certification and audits?

Yes. Because monitoring is performed under the Bahadurgarh lab's NABL TC-7710 accreditation, the reports are accepted by IGBC, GRIHA, and LEED assessors for the IAQ / ventilation credits, by occupational health auditors under the Factories Act, and within pharmaceutical / food cleanroom validation files. Reports compare measured values against the relevant ASHRAE 62.1 / ISHRAE 10001 / IS 15848 (draft) or ISO 14644 benchmark, with the accreditation reference included.
