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(s) of Assessment: June 4, 5, 7, and 14, 2019

No mold growth was identified on visible items within the portable (desk, chairs, etc.).

The Office of the Environment and Building Maintenance (HVAC) inspected the portables HVAC unit. No concerns were identified.

Temperature, relative humidity, carbon dioxide, and carbon monoxide readings were acceptable.

A thermal imaging scan of the portables walls and ceilings was conducted. No signs indicative of moisture intrusion were identified. 

No elevated moisture was detected in the rooms carpeting (present at the doors).

Elevated moisture was detected around both of the portables doors. 

A test cut was made near the floor and the entry door (highest moisture reading) to check the back side of the drywall. The back side of the drywall contained mold growth. The cause of the mold growth was due to a leaking light and a few small penetrations in the portables siding.
