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: August 5, 2024
The Office of the Environment spoke with custodian who informed that staff member believed that staining on carpet and black staining on boxes may be mold. The custodian informed the Office of the Environment that custodial staff had cleaned boxes prior to the site visit. Therefore, the Office of the Environment could not visible determine if the staining was mold.
The Office of the Environment collected temperature (76.6 F), relative humidity (45.5%), and carbon dioxide (553 ppm) readings within the space.
The Office of the Environment used a moisture sensor on carpeted areas. No elevated moisture within the carpet was identified.
Staining on carpet appeared to be from historic spill or water damage.
The Office of the Environment used a moisture meter to measure moisture within the drywall walls. Elevated moisture was identified around the windows in the office.
Water damaged drywall around the windows and water staining on panels underneath the windows was also observed.
Ants were observed entering the office space from the vicinity of the windows.
No visible or olfactory evidence of mold was observed at the time of the assessment, however a moisture issue was identifed and believed to be associated with the window(s)
Building Maintenance to remove water damaged and wet drywall and seal areas to prevent future water intrusion.
Integrated Pest Management (IPM) to address ants and other insects entering into the office space via the exterior wall and windows.
