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: October 2 and 20, 2020
Temperature and humidity readings were collected in the Principals Office and Assistant Principles Office. Temperature (low 70's) and humidity was acceptable (55.9-66.2%).
No odors were present.
No mold growth was observed on surfaces.
No elevated moisture was detected in the carpet or drywall of the offices or the main administrative area.
No recent leaks or odors were reported by custodial staff or administrative staff working in the area.
The supply air diffusers were delivering air to the space (qualitative check).
No concerns were identified above the drop ceiling (Principals Office, AP's Office, or Main Admin Area).
The HVAC unit serving the area was assessed.
The filters were in good condition (recently installed).
The drain pan and coils were in good condition.
The outside air dampers were slightly open (less than 10%). When comparing the unit to other nearby units, it seemed they could be opened further to allow for a greater percentage of outside air to be supplied.
Building Maintenance (HVAC) adjusted the minimum damper position for the Administrative Office Unit (RTU-O). This allows additional outside air to be supplied.
