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)
The black material that had fallen from the ceiling had been discarded.
The Air Handling Unit (AHU) that services the room was inspected.
- The black paper (adhered to fiberglass insulation) was observed to be deteriorated.
- Filter bypass was observed to be occurring.
Building Services (HVAC) will be working with a contractor to remove the deteriorating fiberglass insulation and associated paper. They will also be addressing the filter bypass by installing sheet metal into the gap where the bypass is occurring.
