Indoor Air Quality Investigations

The EPA estimates that 60 percent of the buildings in the United States have poor indoor air quality, resulting in health problems, reduces productivity, and strained landlord/tenant relationships. The latter may foster negative publicity that creates potential liability for building owners.

CECI investigates indoor air quality (IAQ) and mold concerns to evaluate whether a problem exists, pinpoints the most probable cause, and determines the most effective solution


CECI first interviews building occupants to help define complaints, identify symptoms, and locate specific problem areas within a building. Although immediate air sampling may seem the logical response to an air quality problem, it may, in fact, be unnecessary, and could prove to be misleading. Therefore, CECI performs a visual inspection to determine the location of any suspect mold, moisture, or indoor air quality problems.

Since over 50 percent of reported indoor air quality problems are linked to inadequate ventilation, CECI evaluates the heating, ventilation, and air conditioning systems to ensure they are properly designed, constructed, operated, and maintained in conformance with industry standards.

After gathering data from occupant interviews, design evaluations, and any necessary air quality measurements, CECI recommends the most effective corrective actions
