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:  August 22, 2018

Relative humidity mold growth was observed on various surfaces within the gym office.

Surplus furniture was being stored within the gymnasium and had been there for a few weeks.

The gymnasium and gym storage were inspected for additional mold growth. Several pieces of furniture stored within the gym were found to have mold growth.

The mold growth was thought to be related to over cooling (creates condensate) of the office space and/or unconditioned warm humid air from the gym entering into the gym office.  Overall, this summer's extended and excessive moist air was a main contributor.
