Concern
Building Services (HVAC) has been monitoring the relative humidity in several high school auditoriums due to recent relative humidity mold impacts. The Office of the Environment inspected the auditorium based on the recent humidity (elevated) data provided.
IEQ Investigation Process

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)
Findings

The wooden portions of select auditorium seats were impacted by relative humidity mold.

The remainder of the auditorium was inspected, including props, wooden doors, and the catwalk. No other mold growth was observed.

The mold growth was likely due to this summer's extremely humid weather pattern. The area will be monitored for mold growth next summer by the Office of the Environment.
