Building Services had placed humidity data loggers in select areas within the school due to historical issues with mold growth. The recent humidity data trends indicated the potential for mold growth.
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 Office of the Environment inspected perimeter classrooms on the second story of the school. The start of mold growth was observed within two student desks and on the underside of a work table.

The only room observed to have mold growth was Room 15.

The classroom's ventilation unit was operating beyond scheduled hours allowing for the increased introduction of unconditioned humid air into the interior classroom space.
