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 27 and October 7, 2019

No odors were identified during the initial visit (approximately 8AM).

A different individual from the Office of the Environment visited the space on October 7, 2019. A slight "cardboard" aroma was noted that may be from the materials in the room.

Surfaces were inspected for relative humidity mold. No mold growth was identified.

The wood cabinetry was probed with a moisture meter (wood setting). No elevated moisture was detected.

The wood cabinetry (back of room) was coated with fine dust. It appeared the cabinetry formerly housed wood-working equipment (saws, sanders, etc.).

No odors were emanating from the supply vents.

Areas above the drop-ceiling were observed. No odors or environmental concerns were observed.

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

Dead bugs were observed in the light fixture.

Stair-step cracking was observed in the back, right corner of the room.

The air-handling unit (RTU-5) that services the space was inspected. With the exception of the outside air dampers the unit was in acceptable condition. The units outdoor air dampers were closed. 

A definitive odor source was not identified however, the outside air dampers being closed could impact general odors noted in the space. With the outside air dampers closed, the unit would not be able to dilute nuisance odors.

Corrective Actions
October 10th, 2019

Administration is to ensure the blue cabinet in the back of the room is cleaned of saw dust. The Office of the Environment recommends vacuuming surfaces first and then wiping them down.

Building Services (HVAC) is to assess and correct the units outside air dampers

October 10th, 2019

Custodial Services is to clean the dead bugs from the light fixture.

October 10th, 2019

A work order was submitted to Building Services to assess and address the stair-step cracking observed in the CMU block.
