Indoor air quality testing measures CO2 concentration, particulate matter (PM2.5/PM10), volatile organic compounds, and ventilation rate inside sealed, centrally air-conditioned office buildings — a distinct risk profile from industrial air quality auditing, since the concern in an IT office is occupant comfort, concentration, and sick-building-syndrome-type complaints rather than industrial emission compliance.
ASHRAE 62.1 sets minimum ventilation rate guidance widely referenced for commercial indoor air quality, and CO2 concentration above roughly 1,000 ppm is commonly used as a practical indicator of inadequate fresh-air exchange in sealed office floors, a finding the National Safety Council has noted is common in older IT/BPO buildings where HVAC systems were sized for lower occupant density than current desk-seating actually places on the floor.
In an indoor air quality test Elion completed for an IT company building in Hyderabad, Telangana, several floors showed CO2 levels above the 1,000 ppm comfort threshold during peak occupancy hours, consistent with fresh-air supply not having been re-balanced against current desk density. Corrective recommendations — HVAC fresh-air damper rebalancing and CO2-based demand-controlled ventilation — were estimated at ₹2–5 lakh depending on floor count and HVAC system type.
For IT and BPO office buildings specifically, indoor air quality testing has a direct productivity and attrition angle beyond pure compliance — elevated CO2 is associated with reduced cognitive performance and increased reported fatigue in occupied-space research, which makes this one of the few audit categories with a plausible HR/productivity business case alongside the standard occupant-health rationale.
Indoor air quality testing measures CO2, PM2.5/PM10, and VOCs against ASHRAE 62.1 ventilation guidance — CO2 above ~1,000 ppm signals inadequate fresh-air exchange, common in IT offices where HVAC was sized for lower occupant density than current desk seating.

The Importance of Air Quality Testing in the Workplace
Poor air quality in the workplace can have significant negative effects on employee health and productivity. Exposure to pollutants such as volatile organic compounds (VOCs), particulate matter, and carbon monoxide can lead to respiratory problems, allergies, headaches, fatigue, and other health issues. These health problems can result in increased absenteeism, decreased productivity, and higher healthcare costs for both employees and employers.
Air quality testing in the workplace is crucial for several reasons. Firstly, it helps identify potential sources of indoor air pollution, such as inadequate ventilation systems, mold growth, or the use of certain chemicals or materials. By identifying these sources, employers can take appropriate measures to eliminate or reduce them, thereby improving the overall air quality.
Secondly, air quality testing provides valuable data that can be used to establish baseline measurements and track changes over time. This allows employers to evaluate the effectiveness of any interventions or improvements made to the indoor environment. It also helps ensure compliance with relevant air quality standards and regulations.
Location and Background of the IT Company Building in Telangana, Hyderabad
The IT company building chosen for air quality testing by Team Elion is located in Telangana, Hyderabad. The building is a modern office complex with multiple floors and a large number of employees. It is situated in a busy commercial area, surrounded by other office buildings, restaurants, and retail establishments.
The decision to test the air quality in this particular building was based on several factors. Firstly, the building houses a significant number of employees who spend a significant portion of their day indoors. This makes it important to ensure that the indoor air quality is healthy and conducive to productivity.
Secondly, the building is located in an area with high levels of vehicular traffic and industrial activity. These factors can contribute to increased levels of air pollution, both indoors and outdoors. By testing the air quality in this building, Team Elion aimed to assess the impact of these external factors on the indoor environment.
Air Quality Testing Methodology and Equipment Used by Team Elion
Team Elion used a comprehensive methodology to conduct air quality testing in the IT company building. The testing process involved several steps, including site assessment, sample collection, laboratory analysis, and data interpretation.
During the site assessment phase, Team Elion evaluated the building’s ventilation systems, identified potential sources of indoor air pollution, and assessed the overall indoor environment. This information was used to determine the sampling locations and strategies for collecting air samples.
To collect air samples, Team Elion used state-of-the-art equipment, including high-precision air quality monitors and samplers. These devices were capable of measuring various pollutants, such as VOCs, particulate matter, carbon monoxide, and nitrogen dioxide. The samples were collected over a period of several days to ensure accurate and representative results.
Results of the Air Quality Testing and Analysis
After collecting the air samples, Team Elion conducted laboratory analysis to measure the concentration of various pollutants. The results showed that the indoor air quality in the IT company building was below the recommended standards for several pollutants.
The data collected by Team Elion revealed elevated levels of VOCs, particulate matter, and carbon monoxide in the indoor environment. These pollutants can have detrimental effects on human health, including respiratory problems, allergies, and other health issues.
The analysis also showed that the levels of nitrogen dioxide were within acceptable limits. However, it is important to note that nitrogen dioxide is primarily an outdoor pollutant, and its presence indoors may indicate poor ventilation or infiltration of outdoor air pollutants.
Comparison of Air Quality Results with National and International Standards
To assess the significance of the air quality results, Team Elion compared them with national and international air quality standards. The comparison revealed that the levels of VOCs and particulate matter exceeded the recommended limits set by regulatory agencies.
These findings indicate that the indoor air quality in the IT company building was not up to par with the established standards. This suggests that there may be potential health hazards and risks associated with prolonged exposure to these pollutants.
Identification of Potential Health Hazards and Risks to Employees
Based on the air quality testing results, Team Elion identified several potential health hazards and risks to employees in the IT company building. The elevated levels of VOCs and particulate matter can cause respiratory problems, allergies, and other health issues.
Prolonged exposure to these pollutants can lead to chronic health conditions, such as asthma or lung cancer. Additionally, carbon monoxide exposure can result in headaches, dizziness, nausea, and even death in extreme cases.
The presence of these pollutants in the indoor environment indicates that there may be sources of indoor air pollution that need to be addressed. This could include inadequate ventilation systems, the use of certain chemicals or materials, or mold growth.
Recommendations for Improving Air Quality and Employee Health and Safety
Based on their findings, Team Elion made several recommendations to improve the air quality and ensure the health and safety of the employees in the IT company building. These recommendations included:
1. Improving ventilation systems: The building should be equipped with efficient ventilation systems that provide a constant supply of fresh air and remove indoor air pollutants.
2. Reducing or eliminating sources of indoor air pollution: Employers should identify and address potential sources of indoor air pollution, such as the use of certain chemicals or materials, mold growth, or inadequate maintenance practices.
3. Implementing air filtration systems: Installing high-quality air filtration systems can help remove particulate matter and other pollutants from the indoor environment.
