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: April 13, 2026
The space is finished with floor tile, block wall, drywall walls, and a drop ceiling. The Heating Ventilation and Air Conditioning (HVAC) system includes a single Air Handling Unit on the the roof (AHU-13) that is ducted to a single Variable Air Volume (VAV) box within the space (above the drop ceiling).
The temperature (71.5 degrees Fahrenheit (F)), relative humidity (55%), carbon dioxide (468 (parts per million ppm)), and carbon monoxide (0.0 ppm) were acceptable.
Various surfaces were assessed for visible mold growth. No visible mold growth or malodors were identified.
Various surfaces were assessed for general dust. Moderate to heavy dust was observed on various surfaces.
No elevated moisture was detected in the carpet, drywall or casework.
Areas above and below the drop-ceiling were screened with a thermal infrared camera. No thermal anomalies indicative of moisture intrusion were identifed.
The supply air diffuser was delivering air to the space (qualitative check) and the return air was functioning (tissue test).
AHU-13 was assessed:
- The unit was operational.
- The outside air dampers were open.
- The filters were in good condition and no bypass was observed. The pre-filters had moderate dust loading, however this is to be expected in the Spring.
- No concerns were identifed with the units coils or drain pan.
A work order was created for Building Maintenance (HVAC) to assess the functionality of the VAV box as a precaution.
Custodial Services is to perform a general dusting of horizontal surfaces to include desks, bookshelves, file cabinets, the phone, etc. Additionally, the light fixtures will also need to be dusted. The staff member in the space may need to assist in the process by dusting any personal materials and/or moving personal items so that Custodial Services can have full access for cleaning.
