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: November 5, 2019

Flaking/peeling paint indicative of moisture intrusion was observed on the wall.

The missing paint made the bare Concrete Masonry Units (CMU) visible. The black spots observed was pitting in the CMU. No mold growth was observed.

The exterior of the wall was inspected, missing mortar and rust was observed between bricks (indicative of moisture in the wall).

The Office of the Environment contacted Building Services (Roofing). Roofing is already aware of the moisture intrusion and is currently monitoring the situation to identify the likely cause. 

Several roof patches were observed on the roof and may have been historical sources of moisture intrusion.

This area is reported to be receiving a new roof during the Summer of 2020.

A definitive moisture intrusion source was not identified.
