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 22 and March 4, 2019.
The drywall bulkhead beneath the skylight showed signs of water damage (staining). Minor mold growth (<2 square feet) was observed on the back side of the drywall. The area was dry at the time of investigation as determined with the use of a moisture meter (drywall/gypsum setting).
The thermostat cover appeared damaged and set to 76 degrees Fahrenheit. Winter setting is to be 68-70 degrees.
The re-heat coils of the room's variable air volume box (VAV) had moderate particulate buildup on its ends. This may reduce the efficiency (airflow and/or heating).
The ventilation unit serving the Pod was inspected. The condensate pan had rust / scale which during the cooling season may allow condensate to become stagnant or clog the condensate drain.
Housekeeping of the Pod was acceptable. The vacuums used to service the area were inspected and found to be used and in acceptable condition and are equipped with a High Efficiency Particulate Air (HEPA) filter.
Low indoor relative humidity levels were noted within the concern. It is not uncommon and it is expected for humidity levels to be below 30% during the heating season / winter months. The recommended range is 30-60%. Portable humidifiers are not permitted because they can cause clinical environmental illnesses (i.e. humidifier fever) by dispersing bacteria due to lack of maintenance.
A small brown water stain was noted on a ceiling tile.
Building Services will be assessing the source of leak that caused the water damage to drywall and correct as necessary. Once source of the leak is corrected, the damaged drywall will be removed and repaired.
Building Services (HVAC) will assess thermostat setting and operation, clean unit's condensate pan prior to cooling season, and clean VAV coils.
Building Services is to assess the cause of water stained ceiling tile, correct the source, and replace the ceiling tile.
