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 of Assessment: June 16, 2026
The Office of the Environment observed less than one square of mold on the wall within the closet.
No other mold growth was observed within the closet or the classroom.
No elevated moisture was identified in the walls using a moisture meter.
A stained ceiling tile was observed within the closet.
The ceiling tiles were assessed using a thermal infrared camera. No thermal anomalies indicative of an active moisture intrusion issue were identified.
Although a definitive cause was not identified, the sources were likely related to a combination of an historic leak evidenced by the stained ceiling tile and elevated relative humidity over the summer.
The Office of the Environment cleaned impacted areas using a disinfectant.
Building Services (Plumbing) identified a leaking domestic water pipe. Portions of the pipe and associated fittings were replaced.
After repairs were completed, a final visual assessment confirmed that the leak was no longer present.
