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 17, 2025
No moldy/musty odors were observed.
Numerous bookshelves were assessed for visible mold growth. No visible mold growth was identifed.
Note: The root cause of the historic summer mold growth was associated with the Heating Ventilation and Air Conditioning (HVAC) system's design (insufficient dehumidification under certain summer weather conditions). Building Maintenance (HVAC) has altered the design of the system for improved dehumidification.
The Office of the Environment also assessed the HVAC system as part of this concern:
- The outside air dampers were open.
- The filters were in place and in good condition.
- No concerns were identifed with the coils/drain pan.
The Office of the Environment requested custodial services perform a cleaning/dusting of the media center. Custodial Services reported that the task was completed on December 18, 2025.
