IEQ Investigation Process

Identify deficiencies that may impact IEQ and/or sources of odor concerns. Typically includes the following depending on the nature of concern, but not limited to:

  • interview/questionnaire of concern individual(s)
  • inspection above drop ceiling (condition of roof deck, pipe insulation, return air plenum)
  • inspection of ventilation system (operation of variable air volume box and outdoor air dampers, check controls, measurements of carbon dioxide, temperature and relative humidity, sources near outdoor air intake, measure return and supply air volume, cleanliness of coils, liner and condensate pan)
  • inspection of exterior
  • inspection below drop ceiling (housekeeping, sink and floor drain traps, signs of past and present moisture concern via visual and/or moisture meter, mold growth, ensure connection of current and capping of abandoned sanitary vents, odorizers, excessive plants and fabric items, identify potential pathways, and measure volatile organic compounds, carbon monoxide, and lighting)

Date Investigated:  June 20, 2018

  • Mold growth was not observed within the gymnasiums, gym office, or storage.
  • A musty odor was not detected in the above areas.  A slight carpet (aged) related odor was detected within the gym office.
  • With exception to a possible anomaly (i.e. soiled) under right corner of the desk, the carpet was dry as determined by a moisture probe.
  • A few areas under the carpet were inspected. No concerns were observed under the carpet.
  • The temperature in the areas was approximately 72 degrees Fahrenheit which is within comfort guidelines.
  • The relative humidity in the areas ranged from 63.5 – 64.7% which is slightly above comfort guidelines. Building Services HVAC Shop was informed of the relative humidity data and is to watch the operation of the gymnasium ventilation units.
  • The moisture content of the wood gymnasium floors was dry as determined with the use of a moisture meter calibrated to wood.
  • Per work order 77196, Building Services reviewed the operation of the ventilation units serving the gymnasiums and were found to be working accordingly. 
  • Building Services provided relative humidity data on August 23, 2018 from a temperature and relative humidity recording device, placed over the summer.  The data indicated bouts of elevated humidity (70+ %), but not continuous enough to create a potential mold growth concern.
Corrective Actions
July 10th, 2018

Since carpeting should not be located within the gymnasium area, Building Services replaced the carpet in the gym office with floor tile.
