Indoor Air Quality Monitoring for Global Capability Centres (GCCs) in India
India’s Global Capability Centres (GCCs) have evolved well beyond their original role as offshore support handling back-office operations. Today, GCCs function as strategic hubs for product engineering, artificial intelligence, research and development. According to the Nasscom-Zinnov GCC Landscape 2026, India has more than 2,100 Global Capability Centres (GCCs), employing approximately 2.36 million professionals.
This evolution has also changed what a GCC workplace needs to support. Teams may work across multiple time zones, operate in shifts, spend long periods in enclosed meeting rooms and collaborate on work needing sustained concentration. In such environments, indoor air quality (IAQ) is more than a comfort issue. It is part of the physical environment in which high-value decision-making happens.

Why Global Capability Centres
Have a Distinct Indoor Air Quality Challenge
Unlike conventional corporate offices with predictable nine-to-five occupancy, GCC workplaces can experience significant changes throughout the day. An office may be relatively quiet in the afternoon and become heavily occupied later as teams in India connect with colleagues across North America and Europe. These working patterns create three distinct indoor air quality challenges:
- Variable and sudden occupancy: Training sessions, town halls, project meetings and designated collaboration days can create short periods of much higher occupancy, increasing the ventilation required within specific rooms and zones.
- Fixed HVAC schedules: Building systems do not always respond automatically to changing occupancy. An HVAC system may continue cooling a space without adjusting its fresh-air supply. In continuously occupied meeting rooms, this can result in rising CO₂ levels. At typical office concentrations, CO₂ is primarily useful as an indicator of occupancy and ventilation adequacy.
- Outdoor pollution and filtration: Increasing outdoor-air intake can improve ventilation, but it may also introduce particulate matter during periods of elevated outdoor pollution. Facility teams must therefore manage ventilation, filtration, HVAC operations and building design together rather than treating them as separate concerns.
What Happens
When Indoor Air Quality Is Overlooked?
Poor indoor air quality is not easy to notice. A room may look clean and feel comfortable while still having inadequate ventilation or elevated particulate matter. Over time, these conditions can contribute to headaches, fatigue and general discomfort.
A study by GBCI India and Saint-Gobain Research India assessed 30 offices across nine Indian cities. It examined indoor air quality parameters including CO₂, nitrogen dioxide (NO₂) and particulate matter, alongside broader indoor environmental factors such as lighting and thermal comfort. Only one office maintained healthy indoor air quality across the parameters reported. CO₂ exceeded the recommended threshold in 75% of offices, while NO₂ and particulate matter exceeded their respective thresholds in 67% and 63% of offices. Despite these findings, most occupants reported being satisfied with the air, underlining how perception can differ from measured conditions.
For GCCs, this matters because their work depends heavily on concentration, accuracy and timely decision-making. A study led by researchers at the Harvard T.H. Chan School of Public Health followed 300+ office workers across six countries, including India. The research revealed that higher indoor PM2.5 and CO₂ levels were associated with slower response times and lower performance on cognitive tests. Continuous monitoring can thus help facility teams identify when and where these conditions occur, and allow them to take action before they become a recurring workplace problem.
Why GCCs Need Continuous
Indoor Air Quality Monitoring
Periodic indoor air quality assessments offer a snapshot of conditions at the time of inspection. The downside is that GCC workplaces rarely remain static. Occupancy changes between shifts, meeting rooms fill and empty, outdoor pollution varies, and HVAC performance can vary across floors and hours. A reading from the afternoon may not show what happens in the same space during a heavily occupied evening shift.
Continuous monitoring adds the missing dimension: time. It allows facility teams to move beyond asking whether the building passed an assessment and analyse how conditions change during actual operations. They can investigate specific questions: Does CO₂ repeatedly rise in certain meeting rooms or during specific shifts? Does indoor PM2.5 increase when outdoor pollution rises? Are particular floors experiencing recurring air quality issues?
This turns indoor air quality from a periodic compliance exercise into an operational dataset. Historical readings help teams recognise patterns, identify recurring problems and check whether an intervention delivered the expected result.
How Real-Time IAQ Data Creates Operational Value
for Global Capability Centres
An indoor air quality management system can support several priorities at once. Its value is not limited to displaying pollutant readings; it gives workplace, facility and sustainability teams information they can use to manage occupied spaces more effectively.
- Employee wellness and workplace experience: Continuous monitoring provides measurable information about the conditions employees experience throughout the working day. This is useful in meeting rooms, collaboration areas and densely occupied zones, where conditions can change quickly. When teams can identify recurring problems and respond to them, workplace-wellness commitments become more visible.
- HVAC efficiency and demand-based ventilation: Fixed HVAC schedules may ventilate lightly occupied spaces unnecessarily while failing to respond quickly enough to crowded rooms. When real-time IAQ data is connected with HVAC or building management controls, ventilation and purification can respond to actual conditions.
- Shift and space planning: Historical CO₂ and air quality trends can reveal whether evening shifts, collaboration days or recurring meetings place greater pressure on particular rooms and zones. Facility teams can use this evidence to adjust ventilation schedules, room capacities, booking practices or floor utilisation instead of applying the same response across the entire building.
- Maintenance and multi-location management: Historical data helps facility teams move from reactive complaints to evidence-based investigation. They can examine whether CO₂ repeatedly rises in one room, whether particulate levels follow outdoor conditions, and whether readings improve after maintenance. For organisations working across multiple cities, standardised parameters make it easier to compare facilities and hold landlords, HVAC vendors and facility partners accountable.
- ESG reporting and green-building certifications: Indoor air quality links environmental performance with employee wellbeing and governance. Historical readings, threshold alerts and action records can show when an issue occurred, what response followed and whether conditions improved. This information can support ESG reporting, internal reviews and relevant documentation for frameworks such as WELL, RESET and LEED.
For GCCs, the larger benefit is consistency. Continuous indoor air quality monitoring creates a comparable record across shifts, floors and locations, helping teams manage workplace conditions with evidence rather than assumptions.
Aurassure IAQMS:
Translating Air Quality Data into Action for GCCs
A sensor can show that CO₂ is rising or that particulate matter has increased. But the more useful questions are: Where is it happening? How often does it occur? What changed, and what should happen next?
Aurassure IAQMS goes beyond displaying readings. It combines continuous environmental monitoring, AI-driven analytics and compatible HVAC and purification controls, helping facility teams move from detecting a problem to responding and checking whether conditions improved.
Aurassure IAQMS also provides continuous data, historical records and reporting that can support ESG audits and documentation for WELL, RESET and relevant LEED requirements. While certification/ credits depend on project-specific requirements, sensor placement, calibration, data completeness and verification, capabilities offered by Aurassure IAQMS can strengthen certification readiness.
The system brings these capabilities together through a three-step approach: Monitor → Analyse → Act.
Monitor:
The system continuously tracks PM2.5, CO₂, VOCs, temperature and relative humidity. PM2.5 can indicate particulate pollution from outdoor or indoor sources, while CO₂ helps identify spaces where ventilation may not be keeping pace with occupancy. VOC trends may reveal changes linked to cleaning, furnishings or fit-outs. Across a GCC, distributed monitors can also expose differences between rooms, floors and shifts.
Analyse:
Dashboards, alerts and AI-driven analytics combine real-time readings with historical trends. Repeated evening CO₂ increases may indicate a mismatch between occupancy and ventilation schedules, while indoor PM2.5 rising with outdoor pollution may point towards filtration issues. This helps facility teams identify where and when a problem occurs before deciding how to respond.
Act:
When connected to compatible HVAC, building management or purification systems, monitored conditions can trigger actions such as adjusting ventilation or activating air purification. The system then continues monitoring to show whether conditions improved, creating a closed loop from detection to response and verification.
Demand-based operation can also reduce the need to ventilate or cool every space at the same intensity throughout the day. Aurassure reports potential HVAC energy savings of 20–30% through this approach. Actual savings also depend on the building, HVAC configuration, occupancy pattern, control strategy and existing operating conditions.
For GCCs managing multiple floors or locations, this approach creates a consistent view of indoor conditions across the portfolio. Teams can compare spaces, investigate recurring issues, review the effect of maintenance and maintain records for facility reviews, ESG reporting and relevant green-building requirements.
Conclusion: Making Indoor Air Quality Part
of GCC Workplace Strategy
As India’s GCCs take on larger roles in engineering, research, AI and global operations, the workplace becomes part of the infrastructure supporting that work. Indoor air quality is one of its least visible elements, yet it can change considerably with occupancy, ventilation schedules, outdoor pollution and building maintenance.
The objective is therefore not simply to install another monitor. It is to know what is happening, recognise when a pattern is developing, respond when conditions change and verify whether that response worked. By bringing monitoring, analysis and building response together, Aurassure IAQMS helps GCC facility, workplace and sustainability teams manage indoor air quality as a priority rather than an occasional compliance check.
