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: October 16, 2018
No odors were detected.
Relative humidity mold was observed on the underside of three chairs.
The mold growth appeared minimal and would be considered to be "just starting."
The remaining surfaces within the room were assessed. No other mold growth was identified.
The condition of the plenum was acceptable.
Several other ancillary classrooms were inspected. No other mold growth was identified.
The HVAC unit that services the room was assessed by Building Services and was functioning normally.
The cause of the mold growth was likely the extremely humid/moist weather pattern that occurred during the Summer/Fall of 2018.
The room will be monitored during the Summer of 2019.
All of the chairs within the room were cleaned/disinfected by the Office of the Environment.
