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)
The Office of Environment was performing an Indoor Environmental Quality Assessment at West Friendship Elementary School on August 19, 2020. Minor (<1 linear foot) mold growth was observed on two isolated areas of chilled water pipe insulation located above the drop ceiling in the hallway outside of the cafeteria and staff lounge.
On August 26, 2020, the Office of Environment cleaned and disinfected the pipe insulation.
The pipe insulation was damp in some areas due to too cold of chilled water temperature and uninsulated valves and/or drain ends. On August 28, 2020, Building Services raised the chilled water temperature and had a contractor insulate valves and drain ends.
On September, 9. 2020, the Office of Environment applied mold inhibiting paint / encapsulant on the two impacted sections of pipe insulation.
