Does the institution use timers to regulate temperatures based on occupancy hours in at least one building?:
Yes
None
A brief description of the technology used:
Campus HVAC schedules are controlled by the Energy Management System (EMS), which is a Lonworks protocol DDC (direct digital control) system. Schedules are established and verified by Mechanical Services staff who have access to the space scheduling software system. Because TESC buildings are concrete and massive, and the Western Washington climate is temperate, we do not generally operate with a night setback temperature. The general mode of operation is shutting off supply and return fans when the buildings are unoccupied. Exceptions to this occur in the scientific laboratories, where reduced fan speed occurs at night to provide make-up air for the fume hoods. The EMS system does not control Residence Halls. Residence Halls use a control system of their own for central fans, but leave temperature control with the occupants with local thermostats.
A DDC system is not a timer, but TESC meets both the spirit and intent of what this question seeks.
None
