- 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)

The Office of the Environment observed elevated relative humidity (>70%) within the areas serviced by Air Handling Units (AHUs) 3 and 4 during a summer walkthrough and informed Building Maintenance in order for them to investigate.
The Office of the Environment observed visible mold growth in the custodial office (Room 111).
No mold growth was observed in the other rooms serviced by AHUs 3 and 4.
The source of the mold growth is elevated relative humidity within the space due to the Heating Ventilation and Air Conditioning (HVAC) system being tripped while ongoing renovation activities occur.
