Indoor air quality (IAQ) is a high profile issue that affects million of workers around the world. The World Health Organization estimates that as many as 30% of new and remodeled buildings world wide can be classified as “problem buildings” – where productivity is impaired by poor IAQ.

Many issues can affect building air quality – volatile organic compounds (VOCs), formaldehyde, particulate matter, mold and moisture intrusion, and poor ventilation. These issues often find their way into the courtroom where property owners, occupants, attorneys lenders can all be drawn into the equation. The EI Group, Inc. provides comprehensive Indoor Air Quality services, from initial building screening, to air testing, problem building resolution, and litigation support. Our scientists have advised NIOSH, CDC and other federal agencies, on indoor air quality, and have conducted hundreds of problem building investigations.

Let EI professionals assist you in providing effective Indoor Air Quality services, including:


The EI team has been fantastic to work with. ABM had a high profile opportunity with Gallaudet University, a school for the hearing impaired, in the heart of Washington DC. Their focus was to insure the facilities were safe for students and staff to return. EI services were instrumental in determining this by conducting pre and post IAQ analysis on the facilities as we made changes to their equipment. Given the size of the campus, this required extensive coordination and flexibility by the EI team. EI was always able to adjust as needed, participate in sessions with the end customer, and made all their commitments. We are thrilled with the relationship and partnership we have developed with EI and look forward to many more successful projects.

What the EPA’s Newly Released Clean Air in Buildings Challenge Means for Indoor Air Quality

With the onset of pollen season, what better time to discuss indoor air quality? As defined by the Environmental Protection Agency (EPA), indoor air quality (IAQ) is the air quality, specifically as it relates to the health and comfort of occupants, within and around buildings and structures. COVID-19 has increased the population’s general awareness and importance of IAQ as well as the transmission of infectious diseases. The EPA recently released a Clean Air in Buildings Challenge as part of the Federal government’s new IAQ initiative, which happens to also be a facet of the National COVID-19 Preparedness Plan.
