Concern
There was water in this room due to over-condensation earlier this summer, which resulted in a lot of water on the floor leading out of the door into the media center area. Now, there is a very strong overwhelming odor in that room that I would like to have checked out.
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

A "styrofoam" odor was noted within the room.

Several of the objects in the room were assessed for an odor.

The odor appeared to be emanating from the rooms fan coil unit.

The unit  was opened and assessed. The unit appeared dirty. Standing water was observed in the unit (presumably from the summer water incident). The water appeared to be pooled against a strip of Styrofoam within the unit.

Corrective Actions
August 22nd, 2018

The condenser pump (which presumably caused the leak) was replaced. A general cleaning of the unit was performed.

The odor persisted. Building Services (HVAC) then disassembled the unit to better clean it (including the coils).

After the more thorough cleaning, the Office of the Environment visited the site and did not detect the odor.
