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: February 15 and 20, 2019
No odors were sensed by the Office of the Environment on February 15, 2019 (prior to school starting).
No mold growth was identified.
The fan coil unit that serves the room was acceptable.
Areas above the drop-ceiling were acceptable.
It was reported that the odor gets stronger towards the end of the day.
An odor was sensed on February 20, 2019 (end of the school day). The odor was consistent with human bioeffluents (i.e. body odor).
The outdoor air unit serving the room was not operating at the time of the assessment. Lack of outside air would cause odors to increase throughout the day.
Building Services (HVAC) turned the outside air unit back on.
