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: September 12, 2019

A faint stale carpet odor was noted within the space. The odor appeared to be emanating from the carpet.

The wall-mounted return duct was assessed. No odors were emanating from the duct.

The casework and drywall were probed with a moisture meter (wood/drywall setting respectively). No elevated moisture was detected.

The space was screened with a thermal infrared camera. No thermal anomalies indicative of moisture intrusion were observed.

No elevated moisture was detected in the carpet.

An access panel (leading to a clean-out) was opened and assessed. All piping appeared to be connected and no odors were identified within the chase.

Areas above the drop-ceiling were assessed. No concerns/odors were identified.

The Roof Top Unit (RTU) that services the space was inspected.

Mild particulate loading was identified on the filters, however the filters meet the filter replacement schedule (no concerns).

The coils and the drain pan were acceptable. 

The outdoor air dampers were open.

Carpet odors are considered a nuisance (not a safety concern) and tend to dissipate after the HVAC begins operation (dilutes odor).
