Holiday Energy Saving Initiative

Since 2005, NC State’s Holiday Energy Savings Initiative (HESI) has safely lowered building temperatures and utility costs in unoccupied campus buildings during the winter holiday period when the university is closed for about 10 consecutive days. 


The 2018-19 Holiday Energy Saving Initiative will go into effect in stages between December 19, 2018 and January 6, 2019.

  • Temperatures in classrooms and teaching labs will be adjusted Dec. 19 (after final exams) through Jan. 6 (the day before spring semester classes begin).
  • Temperatures in residence halls will be impacted Dec. 20 – Jan.1 while those buildings are closed to students.
  • All other university buildings not exempt from the program will have temperatures set back while the university is officially closed Dec. 22 through Jan. 1. See full calendar



Campus research labs and occupied support spaces are excluded from this program, and an exemption may be requested for other spaces. Exemption requests will be reviewed and the status of each request will be available on this webpage by December 17 at 5 p.m. If you have additional questions, contact

Parking Impacts


Lighting impacts in parking areas are noted in this map. Be mindful that beginning the evening of Dec. 21 through the morning of Jan. 2 the following parking decks will be blocked off and inaccessible: Dan Allen, Coliseum, Partner’s Way, Oval West Deck, Toxicology and MRC. The top two levels of the CBC and West Decks will be inaccessible. Campus partners on Centennial Campus may park in the following areas: Partner’s I lot, Capability lots, Partner’s II lots, Research I, II, & III lots, Poulton Deck and on-street parking along Main Campus Drive.


How You Can Help


In addition to the temperature setbacks, the campus community can save energy by taking the steps below:

  • Turn off lights and office/lab equipment
  • Unplug non-essential electronics (printers, coffee makers, etc.)
  • Clean out and unplug office refrigerators
  • Close lab fume hoods
  • Shut exterior windows and doors
