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: July 29 and August 13, 2024
Approximately five square feet of mold growth was observed on a block wall within the kitchen storage closet.
The wall adjoins the kitchens walk-in freezer.
The cause of the mold growth is likely temperature differentials between the storage closet in the Summer (unconditioned) and the walk-in.
A board approved restoration contractor cleaned/disinfected the impacted areas. The impacted area was then encapsulated.
After the cleaning, a dehumidifier was placed in the space for the remainder of August and into September (when outdoor relative humidity decreased due to seasonal variation). No regrowth was observed after the cleaning.
The Office of the Environment will work with Building Maintenance to have a portable dehumidifier installed during the Summers as a preventative measure.
