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)
Dates of Assessment: November 4 and 5, 2020.
On November 4, 2020, the Office of Environment performed the school's annual IEQ inspection. The window sills of the two windows towards the school showed signs of moisture damage (sill warped in sections and debris generated from ants). The window sills were damp as determined by a moisture meter. The moisture detector did not detect moisture in drywall surrounding the windows.
On November 5, 2020, Building Services and their contractor did further assessment. In addition, they identified rotting wood floor substrate at each doorway. Mold, water damage, and ants were observed within the wall cavity around the windows. The cause was due to poor window and door flashing details along with the door thresholds not being sealed.
The contractor finished demolition, repair, and finishing work on November 13, 2020.
Building Services' contractor removed water damaged materials and made repairs to windows and door details to prevent further water intrusion.
