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: October 19, 2018

No mold growth was identified.

No elevated humidity was identified.

No elevated moisture was detected in the carpet.

No thermal anomalies indicative of moisture intrusion were identified.

Areas above the drop-ceiling were assessed and were acceptable.

The room is serviced by a Fan Coil Unit. Outside air is introduced via a Roof Top Unit.

Building Services (HVAC) assessed the outdoor air unit that services the space. No deficiencies were identified.

The damper on the diffuser (in the space) that introduces outside air was closed. Outdoor air helps to dilute nuisance odors and carbon dioxide. 

Corrective Actions
October 19th, 2018

The louvers on the outdoor air supply diffuser were opened. These dampers should remain open so that outdoor air can be delivered to the space.
