Indoor Air Quality Measurement

An indoor air quality (IAQ) Measurement is taken during an IAQ assessment to isolate the source of health irritations or risks within a commercial building.

Poor indoor air quality can result from indoor and outdoor irritants. For instance, outdoor vehicle exhaust or construction materials are frequently cited as the source of IAQ complaints. Inside your building, wood or coal-burning stoves, biological agents including viruses and aerosols, and carpeting or furniture containing volatile organic compounds (VOCs) can be irritating or cause long-term health problems.

Indoor air pollutants can be natural, like mold or CO2, or part of the building materials, such as asbestos or varnishes. While some of these issues may go away after cleaning, others can linger and worsen due to poor ventilation, high temperature, and high relative humidity (RH), and require professional treatment.

Reactions to air quality pollutants can range from mild to severe, depending on the irritant and its intensity. Typically, poor indoor air quality can cause headaches and fatigue, irritation in the eyes, nose, and throat, and impair cognitive functioning in high concentrations.

If you suspect that your building is making your employees sick, get a professional inspection by a licensed and degreed ATS engineer.

Baseline & Complaint Surveys

We begin with a baseline survey to detect potential sources of indoor air quality complaints. Our engineers will perform a visual inspection of your site to check for obvious signs of pollutants, mold, etc. The HVAC system is a common culprit for indoor air quality complaints. If left unmaintained or improperly installed, the HVAC system can fail to adequately filter and circulate air from inside and outside the building. Old or ineffective filters are an easy fix, but sometimes more robust measures are required.

Finally, the technician performs IAQ measurements for irritants and conditions that can worsen IAQ: the presence of carbon monoxide, carbon dioxide, high temperatures, and high relative humidity (RH). These measurements can occur once or at an 8 to 24-hour schedule. Continual monitoring is also available if you or the inspector believe the decrease in indoor air quality is due to a change in the indoor environment.
Next, our technician performs an IAQ complaint survey to assess for common complaints, patterns, and potential sources. Our engineers will use this time to take air and bulk samples for laboratory analysis and monitor for typical indoor pollutants and dangers. Our in-depth HVAC system assessment provides a detailed understanding of the efficiency of your system’s components, such as airflow, thermostat, and variable-air-volume termination operation.
IAQ Response and Remediation
We will work with you to build a response to the findings from the surveys. Sometimes, the source of a problem can be removed, like an old HVAC filter or a carpet with VOCs. In other cases, repair work can mitigate the problem without necessitating removal, as is the case with asbestos. We will work with you to determine the scope of your needs at a price and schedule you can afford.
A licensed contractor will perform repairs on your HVAC system, plumbing, etc. Our trained professionals will adhere to OSHA guidelines and federal and local regulations:
