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:  December 25 and 27, 2022

On December 25, a sprinkler pipe leaked from above the drop ceiling outside of room 309.  Facilities addressed the source and began drying impacted materials by removing cove base from wood casework, drilling holes in wood base, and placing fans to direct air to the base.

On December 27, the Office of Environment did an assessment using visual cues and moisture detecting equipment.  A section of external ventilation duct insulation was saturated and to be removed and replaced.  The base of the wood casework was dry in the room across across from room 301.  However, the base of some drywall in this room was wet.  The Office of Environment removed vinyl cove base from the impacted drywall and moved fans to force air onto the drywall.  Building Services were instructed to leave fans in place for two days which would be enough time to dry the drywall per its current condition.

The above actions were done to prevent the potential for microbial growth.
