Holiday Shutdown Savings

Saving Energy on Holidays

The Energy Conservation Office is proactive in reducing energy waste on holidays. By leveraging the campus’s complex digital building control system, our engineers implement new holiday schedules and temperature setpoints for building heating, ventilation and air conditioning (HVAC) systems. The result is more HVAC systems are given a holiday too, and room temperatures are allowed to drift. These holiday savings and setbacks only affect administrative and classroom spaces and exclude laboratory and animal spaces.

You wouldn’t leave your home’s heating or cooling systems on while you go on vacation. It would continue to run as scheduled and be an utter energy waste.

- Sam Cole, Energy Project Engineer

During the holidays, some buildings are left completely vacant, which means they don't need their temperatures controlled as tightly. Therefore, temperature settings in these buildings are relaxed significantly during the holidays. 

The HVAC system will kick on if it gets too hot or too cold (say, above 85-90°F, or below 55-60°F). This is to both "protect" the building and prevent building temperatures from drifting too cold or hot in case someone shows up during the holiday.           

- Nico Fauchier-Magnan, Energy Engineer Supervisor

The relaxed temperature settings explained by Nico also prevent long warm-up or cool-down times after the holidays, e.g. shortening the time for a building to return to normal operations after the holidays.
