We can save a lot of electricity.
Why do computers need to be on all Thanksgiving break if no one is going to use them? This applies to even weekday nights/weekends. We should get into the habit of shutting them down when we don't need them. Just think of all the electricity U.Va spends and we students pay for for these idle computers that have been on since the beginning of time.
Classrooms are available from 8 am until 11 pm daily and are used for academic purposes as well as student group meetings. Many rooms had scheduled events in them over the Thanksgiving break.
Also, every night, after normal operating hours, the equipment is updated using remote access, scripts, and other means. The computers are refreshed each night, deleting files which have been added in during the working hours and loading operating system updates and specific configurations for the following day's classes. The hardware used in the rooms--Crestron, Extron, LifeSize, etc. require updates as well, which also happen nightly and during gaps during the day.
We do use equipment Power Setting features when possible. The projectors are turned off every night and ITS Classroom Support already makes an effort to turn these off throughout the day when not in use as well.
