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(s) of Assessment: October 7, 2019

A slight nuisance odor was detected indicative of the materials in the space.

No mold growth was observed within the space.

No paint irregularities indicative of moisture intrusion were observed on the exterior wall. 

No mold growth or moisture concerns were identified above the drop-ceiling. 

No odors were noted above the drop-ceiling.

The Roof Top Unit (RTU) was inspected. The filters and coils were in good condition. The outside air dampers were closed. The outside air dampers being closed would impact odors sensed in the room as limited outside air would be supplied to the space for dilution.

Corrective Actions
October 29th, 2019

Building Services (HVAC) will address the closed outside air dampers and perform a precautionary assessment of the room's Variable Air Volume (VAV) box.
