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 30, 2018 and September 5, 2018
The individual indicated the concern had been resolved once the ventilation issue was corrected (see corrective action below).
Building Services indicated ventilation controls may have been compromised during the roofing and/or fireproofing work which took place over the summer.
The area is served by Air Handling Unit (AHU) 11. The condition and operation of AHU 11 was acceptable.
Prior to this investigation, Building Services reviewed and addressed ventilation controls disrupted by roofing and fireproofing work which occurred over the summer. The roofing/fireproofing work likely impacted thermal comfort.
