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)
Dates of Assessment(s): August 27 and 29, 2024
The room is finished with block walls and a drop ceiling. The room is primarily carpeted, with floor tile located near the sink area.
As odors can be subjective, two different staff members from the Office of the Environment visited the site on different days. No musty/malodors were identifed on either day by either individual.
The cork board on the wall (near the desk) was assessed. No odors were identifed from behind the corkboard and no obvious indications of a moisture intrusion event were observed.
A variety of surfaces were assessed for the visible mold growth. No visible mold growth was observed.
No evidence of leaks were observed under the sink or above the ceiling.
The carpet was probed with a moisture meter. No elevated moisture was detected.
The kickplates associated with built-in cabinetry was probed with a moisture meter. No elevated moisture was detected.
No obvious indications of leaks were observed in association with the sink in the space.
A non-issued aerosol disinfectant was observed under the sink.
Pest droppings were observed under the sink.
The return air vent is located in the opposite corner of the room as the desk. The supply diffuser is located in between the desk and the return and the supply/return are fairly close together. It is possible that some of the supply air provided is being entrained into the return prior to circulating through the room. This may cause stagnant air near the desk, and odors from the room may be more prominent in that location.
Custodial staff was sent a communication to clean rodent droppings using a High Efficiency Particulate Air (HEPA) vacuum.
A work order was created for Building Maintenance to move the supply diffuser closer to the desk/farther from the return, to improve air circulation in the corner of the room where the desk is located.
An aerosol disinfectant spray was observed. Such products are not permitted since they can be an airborne irritant when used. Disinfectant wipes and/or the approved cleaning solution from Custodial are permitted.
