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 14, 20, 2018, and February 12, 2019

No odors were identified within the space on any of the days the Office of the Environment, Building Services (HVAC), or Custodial Services visited the space.

Several markers were observed in drawers of the individuals desk. The markers did not appear to be the source of the odor. The Office of the Environment requested that the markers be re-located during the assessment.

The individuals cabinet/desk doors were removed to look for potential odor sources behind drawers. No potential sources were identified.

The supply duct above the individuals desk contained an air filter (which is unusual for this location). The filter appeared dirty and outdated.

Building Services (HVAC) assessed the unit that serves this location and areas around the unit. No concerns/potential sources were identified.

The Office of the Environment inquired if Building Services (HVAC) uses any chemicals in the system such as glycol (an anti-freeze). No such chemicals were reported to be in use.
