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)

Date(s) of Assessment: June 13, 2019

An odor consistent with a wood-framed portable was present. 

No mold growth was observed.

A thermal infrared screening was conducted. No thermal anomalies indicative to moisture intrusion were identified. 

The thermostat was set too low (69 degrees Fahrenheit (F)). The portables thermostat will be reset as the system-wide set point has been changed to 78 degrees F.

Water was present within the HVAC unit. It could not be determined if the water was from the condensate line or from the exterior (rain). No mold growth was observed.

There is a small ceiling tile stain above the white-board (no mold growth observed).

The drywall near the exterior doors contained slightly elevated moisture. 

The drywall was removed in the location of elevated moisture content. No mold growth was observed behind the drywall.

The wood framing (behind drywall) was probed with a moisture meter (wood setting). No elevated moisture was detected in the wood studs.

Building Services (HVAC) determined that the water observed within the units was from overflowing condensation pans. The condensation pan drains were cleaned and the condensation lines were re-ran to better drain away from the structure.
