Indoor Air Quality Assessments

ECG understands the importance of responding quickly to our clients when indoor air quality problems arise. We can typically be on site to investigate your IAQ issuewithin 24 hours of a service request.

Two factors commonly involved with indoor air quality problems are pollution sources and the heating, ventilating and air conditioning (HVAC) system. The pollutant is a source of contamination that causes odors, various physical symptoms, and/or discomfort. The HVAC system can be a source of contamination, or, when not operating properly, it can fail to effectively control air contamination and ensure thermal comfort (temperature and humidity).

The 10 most common indoor air pollutants and parameters include:

  • Asbestos
  • Carbon monoxide
  • Carbon dioxide
  • Sulfur dioxide
  • Nitrogen dioxide
  • Volatile Organic Compounds
  • Formaldehyde
  • Particulates
  • Temperature
  • Relative humidity

ECG has extensive experience with indoor air quality investigations and testing. We also provide annual testing services for several buildings in the downtown Chicago area.

ECG has conducted several IAQ projects related to the Leadership in Energy and Environmental Design (LEED) specification, outlined in LEED for New Construction Version 2.2, Credit 3.2.

Currently, ECG is an approved provider of IAQ services for: JPMorgan Chase, Jones Lang LaSalle, The John Buck Company, Roosevelt University, Northeastern Illinois University, MB Real Estate, ComEd, The John Hancock Center, Inc., and Grubb & Ellis.

When selecting an environmental consulting firm


“We contacted ECG to get help with a stubborn indoor air quality problem at our facility. Another environmental company had tried, but failed to identify the source of the problem. During their site visit, they really impressed us with their ability to quickly identify the problem and propose a solution.”
