"---" indicates that no data was submitted for this field

Does the institution use timers to regulate temperatures based on occupancy hours in at least one building?:
Yes

A brief description of the technology used:

The university uses a Siemens APOGEE-based Building Automation System (BAS) to provide normal temperature and humidity control for approximately 80% of campus buildings. Beginning in 2009, Virginia Tech’s Facilities staff began implementation of time-of-day scheduling of HVAC Air Handler Unit operation and associated chilled water flow based on occupancy rates in non-critical buildings. Academic year nighttime and weekend automatic schedules are programmed for approximately 30% of campus buildings as well as further reduced schedules for extended breaks and summer operation.
