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 28 and 31, 2025
Approximately 13 square feet of mold growth was observed on the block wall within the storage closet.
A temperature differential was identifed on the block wall. Ambient block temperatures were approximately 69 degrees F while the block wall adjoining the walk-in freezer was approximately 64 degrees F. Under certain temperature/humidity conditions, the cooler block wall likely reaches the dewpoint of the surrounding air and condensation forms along the wall.
The Office of the Environment requested Food and Nutrition Services utilize their refrigeration contractor to assess the walk-in freezer for deficiencies related to seals, leaking, and insulation.
A work order was created for Building Maintenance (HVAC) to perform an general cleaning/preventative maintenance of the wall-mounted unit. Additionally, the temperature settings during cooling operations were checked and were set too low. It is believed that the thermostat in the storage room was tampered with during the summer.
A board-approved restoration contractor cleaned/disinfected and encapsulated the impacted block wall.
