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 18, 2019

Conducted on a non-school day, no occupant present, and between 12-12:30 p.m.

The day before the assessment, the area had received a significant rain event.

The drywall was probed with a moisture meter (drywall setting). No elevated moisture was detected.

A ceiling tile had a minor brown water stain. This was dry at the time of the assessment.

Wood sided Portables such as this have an inherent odor and varies in intensity and is usually detected upon entering. Occupants then become acclimated / desensitized.  The odor is thought to be related to building construction materials (i.e. wood roof deck with fiberglass batting insulation and/or occupant odor over time due to the inability of the ventilation units to introduce outdoor air (used to dilute body odors).

The thermostats were properly set for fan and cooling mode.

The condition of the ventilation units were acceptable.

The air filter in the left ventilation unit was found on the floor of its closet.

The exterior wood siding (one side) had a panel detaching from the bottom and located between the two windows. 

Corrective Actions
October 22nd, 2019

Building Services will assess and repair the exterior wood panel.

October 22nd, 2019

Building Services will address air filter by inserting spacers and/or finding a better sized filter.

October 22nd, 2019

The Office of Environment does not address thermal discomfort.  This is a Building Services matter and should be reported to them by the school after Custodial staff performs some general temperature readings.  The thermostat may need to be set to auto mode (cooling / heating) if equipped and to the appropriate set points.

October 22nd, 2019

If the stained ceiling tile is not already being addressed, the school is to submit a work order to Building Services.
