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

Relative humidity mold growth was observed in localized areas on the carpet.

A musty odor was observed within the kindergarten rooms.

Building Services (HVAC) was contacted to assess the ventilation unit that services the room. A refrigerant line had broken. Humidity was not removed from the outside air due to the broken refrigerant line.

Corrective Actions

A board-approved restoration contractor cleaned/disinfected the carpet. A precautionary cleaning was conducted on the remaining surfaces (desks, chairs, etc.) within the room. Air scrubbers equipped with High Efficiency Particulate Air (HEPA) filters were operated during the cleaning. The air scrubbers were left in place for approximately 24-hours after the cleaning.
