Note: The Office of the Environment has recently transitioned to a new Online IEQ platform (as of August 2018). The new platform does not allow the back-dating of IEQ concerns. This concern is inappropriately dated September 28, 2018. The concern should be dated August 1, 2018.
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 investigation: August 10, 2018
A slight odor was detected and thought to be the inherent odor associated with the newer portables.
The flooring (trial) was relatively new and not sealed with wax by the custodial staff. The flooring may have contributed to the slight odor.
No volatile organic compounds were detected within the portable or up against the flooring with the use of a photoionization detector.
No mold growth was observed.
No wall cavity moisture concerns were discovered per visual and with the use of a moisture meter.
A water stained ceiling tile (no mold growth) was observed in the closet.
The cleanliness of the ventilation unit was acceptable. However, the operation of the outdoor air damper was in question.
Building Services has decided to replace the trial flooring with HCPSS standard floor tile scheduled for October 2-5, 2018.
Work order #81477 was submitted to address the stained ceiling tile. Building Services patched a hole in the roof. Custodial staff can replace the ceiling tile.
Work order 81683 was submitted to address the uncertain operation of the ventilation unit’s outdoor air damper. Building Services indicated all components were functional.
