Summer Energy Saving Initiative

Utility costs are among NC State’s largest expenses, and summer presents a strategic opportunity to save energy, particularly during evening hours and on weekends when many buildings are unoccupied. Campus buildings with classrooms are being reviewed for energy saving opportunities during Summer I and Summer II sessions. After the last scheduled class or event of the day (based on schedules provided by the University Registrar), air conditioning levels will be reduced so that the university is not paying to cool unoccupied spaces (research areas and other critical spaces are excluded from this initiative). When unoccupied, indoor temperatures will be allowed to increase up to 80ºF. These energy-saving settings, which occur mostly in the evenings and on weekends, will automatically adjust so that normal building temperatures are restored before the building opens the following morning.

Frequently Asked Questions

Are labs or critical server rooms impacted?

Some teaching labs will be impacted, but labs designated for research are excluded from this initiative. Rooms with critical servers requiring precise climate control will also not be impacted by this initiative.


I just added an event that’s after my building’s air conditioning schedule. What do I do?

If the event is scheduled through the University Event Scheduler at least 48 hours in advance of the event, a work order will automatically be submitted to adjust the air conditioning schedule and you won’t have to do anything in addition to scheduling your event. If you do not schedule the event via Astra, there are two options for overriding the air conditioning schedule. First, the facilities liaison for your building can submit a work order 48 hours before the event so that the air conditioning schedule can be modified in advance. Or, many buildings have a wall-mounted override switch, which will allow for a one-time override of the building’s energy-saving schedule. One switch is located on each floor and is identified by a gray sign (see photo). It can take up to an hour for normal temperatures to be restored, so submitting a work order in advance is preferable.

Why was my building chosen to be part of this summer energy saving initiative? 

Some of the university’s buildings have been equipped with sophisticated temperature controls that allow the air conditioning levels to be adjusted remotely and scheduled in advance. Buildings with this capability are part of this energy-saving initiative.

Why do some buildings just have classrooms impacted and other buildings are impacted as a whole?

Some campus buildings are equipped with special zoning equipment that allows air conditioning levels to be adjusted in just classrooms while keeping surrounding offices, labs and lobby areas at normal operating temperatures. In those buildings, the temperatures in unoccupied classrooms might be setback beginning at, for example, 2 p.m. even though the entire building isn’t setback until 5 p.m.

Who is in charge of this initiative?

This initiative is a collaborative effort of the University Registrar, University Sustainability Office, Energy Management and Building Maintenance and Operations. If you have questions or concerns about this initiative, contact or call 513-3244. This initiative is similar to the Winter Holiday Energy Saving Initiative that the university has done for more than a decade.

When will schedules be posted?

HVAC schedules will be posted on this webpage prior to the beginning of each summer session.
