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: March 4, 15, and 16, and April 1, 2026
The classroom consisted of concrete masonry unit (CMU) and drywall walls, drop ceiling tiles, and vinyl floor tiles.
No visual evidence of leaks or water intrusion was observed in association with the sinks or above the ceiling tiles.
No evidence of visible mold growth was observed within the classroom or above the ceiling tiles.
No thermal anomalies indicative of moisture intrusion were detected using an infrared camera.
The drywall walls and wood cabinetry were assessed for elevated moisture using a moisture meter; no elevated moisture levels were identified.
No malodors were detected at the time of the assessment. When asked, staff members present also indicated that they had not noticed any malodors in the classroom.
A data logger was placed within the classroom between March 15 and April 1 to measure temperature, relative humidity, dew point, and carbon dioxide levels. The measurements collected did not indicate any obvious deficiencies in the Heating, Ventilation, and Air Conditioning (HVAC) system.
The HVAC system consists of a Dedicated Outside Air System (DOAS) that supplies outside air to the room, as well as a Fan Coil Unit (FCU) and a Variable Air Volume (VAV) box that controls the temperature within the space.
The Dedicated Outside Air System (DOAS) was found to be operational, and no obvious deficiencies were noted. The FCU and VAV box will be evaluated by Building Maintenance (HVAC) as a precaution.
Building Maintenance (HVAC) to investigate the FCU and VAV Box that service the room for deficiencies and provide routine maintenance.
