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 28, 2018
No mold growth was identified.
In general, the room is cluttered. Various materials such as plastic furniture, toys, bean-bag chairs, etc. were present within the room.
An odor was present within the room that seemed consistent with the various materials noted above. As temperature and humidity fluctuate in the room these various materials may off-gas, giving off various odors.
Several toys were present on the rooms Fan Coil Unit (FCU). The condition noted above may be exacerbated by the materials proximity to the FCU, especially during heating season.
A microwave and refrigerator were present.
Food items were not stored in plastic containers.
The fiberglass insulation (along the rooms exterior wall) was inspected. No signs of moisture, mold, or water staining were present.
A thermal imaging survey was conducted. No signs of elevated moisture were detected.
A moisture meter was used to sample the rooms casework for elevated moisture. No elevated moisture was detected.
The rooms FCU was inspected. No concerns were identified with the FCU's coils or filters.
The Roof Top Unit (RTU) that supplies outside air to the space was inspected. No concerns were identified.
Regarding the room above B24 (Room D-13):
- An extensive IEQ investigation (related to an odor concern) which included multiple visits did not identify any mold growth within Room D-13 (Fall/Winter 2018).
The Office of the Environment does not recommend microwaves and refrigerators in classrooms (energy consumption). Administration should determine if these items are necessary for instruction.
In general, the space is extremely cluttered. Many of the items in the space are also fabric. Administration should discuss the clutter with the teacher as this makes it very difficult for custodial staff to properly clean. Additionally, items brought in by teachers need a plan to be cleaned regularly as custodial staff are not responsible for cleaning items the teachers bring in.
Administration should alert teachers that items should not be stored on the outlet vent of the room's FCU.
Administration should inform staff that food should be stored in sealed containers to limit pest concerns.
