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: September 18, 23, and 25, 2019.
Involved review of areas 17, 28, 29, 36, 39, 59, and 65.
An outstanding and/or unusual odor was not detected during the investigation.
Air handling units 1 and 2 (within a penthouse) serving the PODs in front of the school and unit 7 (located in loft off the side of the stage) serving pre-k were reviewed. With the exception of the exterior portion of the condensate pan of units 1and 2, the condition and operation (i.e. outdoor air dampers) of the components were found to be acceptable. The exterior portion of the condensate pan, where it connects to the drain had a buildup of scale that could block the drain and/or not to allow condensate to flow out from the interior portion (within the unit) of the pan. Scale was floating on a top of condensate in unit 7.
Building Services (HVAC) has data loggers throughout the school (since May 2019) for their purposes. The data loggers recorded temperature and humidity. Data loggers indicated occupied temperatures (73-75 degrees) and relative humidity (<60%) were acceptable since placement.
Mold growth was not observed on inspected surfaces within the areas assessed.
No deficiencies were observed above the drop-ceiling. The roof deck consisted of steel.
Housekeeping was acceptable.
In viewing the kindergarten and pre-k areas, it appears tents and other fabric items (clothes, pom-poms, etc.) are being used.
The carpet (where relevant) was dry as determined by a moisture probe.
Building Services will clean scale from condensate pans in units 1, 2, and 7.
Consider removing and/or cleaning reading area items, role playing clothes, and/or pom-poms if symptoms appear to start or become exacerbated when items are in use.
