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 8, 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 9, 2018.
The Office of Environment confirmed mold growth and expanded the investigation to include adjacent hallways and rooms to determine the extent of surfaces impacted. Numerous materials were impacted including doors, seating, and various miscellaneous materials.
The cause was due extreme continuous moist air this summer and possibly respective ventilation units control set points being set too low which may have cause the space to be "over-cooled."
Surfaces and materials in impacted rooms were HEPA vacuumed and/or disinfected in the mini-theater, Rouse Theater (including catwalk area), stagecraft area, and hallway leading from loading area to the Rouse Theater.
A Board approved restoration company performed the cleaning and disinfection.
A Board approved IEQ consultant was hired to provide daily oversight and clear the project.
The entire project was completed September 10, 2018.
Once completed, Building Services and the Office of Environment have been monitoring areas using data loggers recording relative humidity and temperature along with weekly inspection of surfaces. No additional concerns have been identified to date.
