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: December 17, 2025
Temperature, relative humidity, and carbon dioxide readings were found to be acceptable.
Walls were found to be non-porous except for a wall adjoining science storage. No elevated moisture was identified in this wall via moisture meter.
Elevated moisture readings were identified within the wood kickplates underneath several sink cabinets.
A malodor was observed underneath a sink cabinet due to stored milk jugs (used and not rinsed). Staff member indicated that they were probably used for the gardening club and would be discarded.
Two Fan Coil Units (FCUs) were observed within the room. Filters appeared to be in good condition and dated 12-1-2025. Staff member reported that a leak associated with the fan coil unit closest to front of the classroom occurred earlier in the school year. Staff member indicated that the technician was to return to replace water damaged fiberglass pipe insulation. Insulation debris was observed near the FCU.
No obvious visual indications of mold were observed below or above the ceiling tiles at the time of investigation.
Outside air is supplied to the classroom via a dedicated Outside Air Handling Unit (OAHU) on the roof. The outside air dampeners were observed to be open and filters in good condition.
Visible deposits of dust were observed to be collected on shelves and built-in cabinetry.
A datalogger was placed in the classroom to collect temperature, relative humidity, dew point, and carbon dioxide readings. The datalogger was collected on January 5th, 2025. Readings did not indicated deficiencies.
Building maintenance (Carpentry) removed vinyl cove base to expose wooden kickplates underneath the sink cabinets. One of the kickplates from was removed from each sink cabinet to provide access to the backside of the wooden kickplates.
Minimal water damage was observed in locations with elevated moisture readings.
No visible mold was identified except for on the backside of one kickplate associated with sink station "7".
The impacted kickplate was removed and replaced. The remainder of the kickplates were allowed to dry.
Kickplates were found to be dry on 12-30-25.
The vinyl covebase was reinstalled on 1-5-2025.
Custodial staff were informed by area manager of deposits of dust and requested the area be thoroughly cleaned.
Building Services (HVAC) conducted an investigation on the FCUs within the classroom and did not identify deficiencies.
The above mentioned pipe insulation debris (fiberglass) was removed.
