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)
Findings

Date of Assessment:  August 26, 2021

An odor was not detected at the time of the visit.

The back side of supply air diffusers had spotting/grime.

Furniture surfaces were inspected for mold growth.  Suspect appearance (cleaning residue or lint from cleaning rag) was observed under one work table.  The table was cleaned /disinfected as a precaution by the Office of Environment.

The thermostat's fan mode was set to "on" instead of "auto" which allowed the fan to operate 24/7.  This can increase humidity levels within the portable dependent upon weather conditions.  Increased humidity may alter aromas of contents and building materials within the portable.  The fan mode was set back to "auto" since the the portable is used as an office and not heavily occupied. 

Corrective Actions
September 24th, 2021

Building Service is to replace supply air diffusers with new.
