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)
January 16, 2026 (D17 and D18)
When speaking with individual, it was noted that a "glue" odor occurred about two weeks ago.
Volatile Organic Compounds were detected (less than 0.5 part per million (ppm) in the space. This was presumably associated with renovation activities that were occurring across the hallway. The construction/renovation activities were observed and no paint/adhesives/etc. were in use. Additionally, no VOCs were detected in the work areas (drywall and electrical work was occurring). VOCs were detected in the hallway outside of the space (no work occurring). A definitive source was not identifed.
The supply diffusers were assessed qualitatively and were delivering air to the space providing general dilution.
It was reported that the construction team would alert the individual if chemicals are planned to be used. The Office of the Environment requested the individual also alert the Office so measurements could be collected/work practices could be observed.
April 14, 2026 (D008)
Rooms D17/D18 were no longer in use. The space now being used was the newly renovated D008.
The Office of the Environment was alerted of a chemical odor in this space. Upon arrival a "newness' odor attributed to new construction was identifed. VOCs were detected in the space from 0.1-0.6 ppm.
Additionally, roofing activities were occurring on the "C" Building, which was upwind of D008. VOC readings were collected downwind of the the roofing activities. No VOCs were detected outdoors, downwind of the roofing activities/outside of D008.
The supply differs were assessed qualitatively and did not appear to be delivering air to the space. The Office of the Environment spoke with the Construction Manager and alerted them that the newly installed unit was not operational. It was indicated that the breaker had tripped that morning, however they were unaware that the unit had not been operating. As it was a warm day, the lack of cooling likely exacerbated VOC off-gassing.
The unit was reported to have been repaired on April 15, 2026. The Office of the Environment returned to the space the morning of April 16, 2026. A newness odor was still detected, however VOC readings did not exceed 0.1 ppm. VOC off-gassing associated with new materials will continue to occur. The general ventilation provided by HVAC is expected to dilute the VOCs. Off-gassing will continue to occur and the "newness" odor will diminish.
The Office of the Environment requested that the Construction Manager alert us directly if any chemicals are going to be used in the D Building to that monitoring could continue.
