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)
The Office of the Environment visited the room early in the morning. No odors were identified.
No elevated moisture was detected in the carpet.
No thermal anomalies indicative of moisture intrusion were identified.
No mold growth was observed.
The plenum was assessed and was acceptable.
The ventilation unit that services the room was assessed and was acceptable.
Carpeted classrooms can have a nuisance odor early in the morning. The odor then becomes diluted by outside air, which is introduced through the ventilation system.
Removing the carpeting for the purposes of science demonstrations should be discussed with the school's administration.
