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)

Rooms 70 and 71
Roof Top Unit (RTU) #1 serving the area was found in acceptable condition.
No issues were observed within the dedicated outdoor air RTU serving the first floor.
The fan coil units within the room were in acceptable condition.
Mold growth was not observed on inspected surfaces.
An outstanding odor was not detected. However, a slight chemical like aroma was detected in room 70. The rooms has several cleaning products on the sink counter and within cabinetry.
Three non-approved chemicals were observed in the cabinet above the sink. Two were pesticides (against the law and school procedures) along with a "Goof Off" product.
A small brown water stain was observed on a ceiling tile and appears to be from a condensate line from a ventilation unit in the above classroom.
Overall housekeeping was acceptable. However some shelving on the exterior wall had moderate dust build up.
A small section of the chilled water pipe insulation above the drop ceiling had suspect mold spotting.
The exterior wall and book case did not show any signs of moisture intrusion and was dry as determined with the use of a moisture meter calibrated for wood.
No visual signs of moisture concerns with the drywall bulkhead located under the skylight.
The outdoor air dampers in RTU 2 serving the media center were found to be closed.
Overall housekeeping was acceptable and comparable to other HCPSS media centers. A few shelves were found to have moderate dust buildup.
The unapproved chemicals were given to custodial staff. The custodial staff were to inform the teacher so the products could be taken home.
School administration is to inform custodial staff to improve housekeeping of the media and bookcase shelving in room 70.
The stained ceiling tile was addressed by Building Services. Building Services reviewed and addressed by tightening clamps, checking for leaks, and replacing ceiling tile.
Per work order 92306, Building Services reviewed and could not conclude the cause for the discoloration. The insulation was dry at the time of their visit. Building Services will work on scheduling the replacement of the questionable section of pipe insulation.
Per work order 92304, Building Services found the outdoor air dampers on RTU #2 serving the media center to be closed. In addition, the return fan was not operating. The return fan was replaced and over ride control for the outdoor air dampers was corrected.
