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

Date(s) of Assessment: December 7, 2018

Relative humidity mold growth was identified on two (cubbies). Both cubbies were covered up by curtains during the time of the assessment.

Relative humidity mold growth was not observed on any other surfaces inspected within the room.

No odors were present during the time of the assessment.

No elevated moisture was detected in the carpet.

No elevated moisture was detected in casework, cubbies, etc.

The Fan Coil Unit for the room was operating during the time of the assessment (early morning). The timing of the units operation was in question.

Building Services (HVAC) indicated the unit was running as scheduled. The room was operating on "morning warm-up mode." However, it was found that the morning warm-up sequence was utilizing outside air.

The plenum was assessed and was acceptable.

Several nearby rooms were also inspected for mold growth. No visible mold growth was identified.

The cause of the mold growth within the room was due to this summer's extremely moist weather pattern. The curtains also appear to have played a role by limiting air flow behind them.

Corrective Actions
December 7th, 2018

The mold growth was cleaned/disinfected upon discovery. Administration was to direct the teacher to remove the curtains to be laundered.

December 10th, 2018

The optimum start sequence was altered to not include outside air. Changing the sequence should increase the efficiency of energy use.

December 17th, 2018

Administration should remind staff that the IEQ program does not recommend curtains as they represent a fire hazard.
