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: January 24, 2019 and March 21, May 13, and July 8, 2019

January 24, 2019

The weather was rainy.

A slight odor resembling dirty water was identified in Room 156 by the Office of the Environment. A source was not identified. 

An odor was not sensed by the Office of the Environment in the adjoining rooms (155 and 154).

No thermal anomalies indicative of moisture intrusion were identified within the Rooms.

No odor was sensed within the Air Handling Unit (AHU) serving the area.

There is a sink located in the main hallway of the pod. Building Services (Plumbing) assessed the trap and did not identify any concerns.

The occasional flooding in Room 156 is to be addressed by Building Services as noted in IEQ report CXCLES201800002A. As an odor was detected by the Office of the Environment in 156, the odor sensed in adjoining rooms by others may be associated with the cause of the occasional flooding.
