Concern
Classroom has a musty odor. I cannot identify the source of the smell. I first noticed the odor when I returned to work 8/21.
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: August 29 and October 16, 2019

No odors were identified during the assessment, however others in the room indicated an odor was present.

No elevated moisture was detected in the carpet.

Temperature, relative humidity, and carbon dioxide were acceptable.

No odors or concerns were identified above the drop ceiling.

The sanitary vent was connected. 

The Fan Coil Unit (FCU) that services the room appeared to be leaking water from the units drain pan. 

The Dedicated Outside Air Unit (DOAU) unit that services the room was not operational. One of the purposes of a DOAU unit is to dilute nuisance odors.

The Office of the Environment returned the morning of October 16th to check the space. A faint carpet odor was noted prior to the HVAC's operation.

Carpet odors are considered a nuisance (not a safety concern) and tend to dissipate after the HVAC begins operation (dilutes odor).

Corrective Actions
August 29th, 2019

The Office of the Environment contacted Building Services (HVAC). Building Services was able to turn the DOAU back on using the Building Automation System.

August 30th, 2019

Building Services (HVAC) assessed the Fan Coil within the Unit and did not identify any issues. The condensate drain was purged as a precaution. As of October 16, 2019, there is no standing water in the unit.
