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:

WE DO NOT USE SET BACK CONTROLLERS. THEY ARE NOT ENERGY SAVERS FOR AN OVER-THE-NIGHT PERIOD OF TIME. WE USE VARIABLE VOLUME HVAC SYSTEMS WITH CO2 MONITORS. THIS TYPE OF ARRANGEMEMENT RAMPS THE INCOMING AIR SYSTEM DOWNWARD WHEN BUILDINGS ARE UNOCCUPIED AND THE CO2 SENSORS ARE SET AT 800 PPM. WHEN THE CO2 LEVELS ARE BELOW THE 800PPM LEVEL THE MINIMUM OUTDOOR AIR SETTING ALLOWED IS ACHIEVED, TYPICALLY WHEN BUILDINGS ARE UNOCCUPIED. WHEN THE 800 PPM CO2 LEVEL IS REACHED THE OUTDOOR AIR DAMPERS OPEN TO BRING IN MORE OUTSIDE AIR.


The percentage of building space (square footage) with timers for temperature control:
