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.
- Temperatures in classrooms and teaching labs were adjusted Dec. 19 (after final exams) through Jan. 5 (the day before spring semester classes began).
- Temperatures in residence halls were impacted Dec. 20 – Jan.1 while those buildings were closed to students.
- All other university buildings not exempt from the program had temperatures set back while the university was officially closed Dec. 21 – 29. See full calendar
Building Information and Exemption Process
An exemption process is available for specific buildings. The deadline to request an exemption has passed. Requests have been reviewed and results are posted below.Approved Requests Declined Requests
To date, the program has saved the taxpayers of North Carolina more than $4 million. Read more about the program’s success in 2019-2020.
Ways To Save
Here are steps you can take to help maximize energy savings over winter holiday.
- Save and secure. Shut exterior windows and doors to boost security and energy efficiency.
- Hit the switch. Turn off overhead and task lighting before leaving your office, residence hall or lab.
- Pull the plug. Turn off nonessential electronics such as coffee makers, toasters, radios, fans, printers, scanners and other small appliances. Consider also powering down your computer and unplugging desk-side devices or chargers.
- Clear the fridge. If you don’t want to return to a smelly break room refrigerator in January, consider cleaning before you leave for winter holiday. Empty refrigerators can be defrosted and left unplugged for energy savings (be sure to leave the door open).
- Shut the sash. Lab users should close all fume hood sashes and power down non-essential lab equipment. Because labs use more energy than any other type of campus building, small efforts here can make a big difference in energy costs.
