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

Mold growth was observed on two bulletin boards and on the side of a bookshelf.

The room is serviced by its own individual Fan Coil Unit (FCU). Building Services (HVAC) assessed the unit and did not find any deficiencies.

A discussion with the teacher indicated that the office door (which adjoins the gymnasium) may have been left open during the summer. 

Gymnasiums typically become very humid during the summer due to their construction/HVAC systems. Humidity from the gymnasium likely migrated into the office due to the open door and/or formed condensation when contacting cooler surfaces within the office.

No mold growth was observed in the gymnasium at the time of the assessment.
