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: February 28 and March 4, 2020
The room consists of block walls, carpeting, and a drop-ceiling. Casework and a sink are located in the back of the room.
No visible mold growth was observed in the space.
A slight odor was sensed upon entering the room. The odor was indicative of carpeting.
Temperature (7.1 degrees Fahrenheit (F)), carbon dioxide (671 parts per million (ppm)), and carbon dioxide (0.0 ppm) levels were acceptable.
Relative humidity would be considered low (16.5%), however this is typical for HCPSS schools as the ventilation system does not humidify air before introducing it to occupied spaces. Humidification can introduce clinical health conditions such as humidifier fever.
No elevated moisture was detected in the rooms carpet.
No elevated moisture was detected in the rooms casework (particularly under/around the sink).
No thermal anomalies indicative of elevated moisture were identified.
An odor eliminator was observed stored in an upper cabinet (left of the sink).
The Roof Top Unit (RTU-3) that services the space was in good condition. The outside air dampers were open and the coils and filters were observed to be in good condition.
The volume of air being delivered to the space was measured (190 cubic feet per minute). This measurement is within 10% of the designed specifications and is acceptable.
Building Services (HVAC) assessed the unit. Static pressure was determined to be slightly lower than designed within the rooms Variable Air Volume (VAV) box.
Administration is to have the odor eliminator spray removed. Air fresheners are restricted due to their potential to cause allergic reactions and they may mask an odor/building deficiency that requires maintenance/repair.
The static pressure in the VAV box was slightly increased. The increase will deliver slightly more outside air into the space and may help dilute the nuisance carpet odor.
