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)

Dates(s) of Assessment: October 19, 2018

A light green film was observed on the screen of the PA speaker. The film is assumed to be mold growth.

No additional mold growth was observed on surfaces within the room (desks, chairs, cabinets, etc.).

The fan mode on the thermostat was set on the "on" position as opposed to the "auto" position. This means the fan for the HVAC system continuously ran, delivering humid outside air into the space.

No thermal anomalies indicative of a moisture intrusion issue were observed.

No elevated moisture was detected in the drywall.

Corrective Actions
October 19th, 2019

Custodial Services performed a precautionary cleaning of all surfaces within the space. The tennis balls (on the bottoms of chairs) were removed as a precaution as they are a porous surface that cannot be easily cleaned.

October 19th, 2019

The thermostat was reset to the "auto" position. 

October 29th, 2019

The speaker was removed and replaced.
