Computer Power Management
As of September 2013, the Office of Information Technology (OIT), in partnership with the Campus Sustainability Office (CSO) has applied power management to most campus computers and monitors. The resulting energy savings will directly support the goals of our Climate Action Plan, save University funds to be spent elsewhere, and promote the sustainability mission that is central to PSU’s values.
- Out of approximately 6,000 computers on campus, 5,000 now have power management settings applied. This amounts to a savings of approximately 15,000 kWh every month, or 180,000 kWh per year!
Power management settings save energy by putting a computer and monitor to sleep after a certain period of inactivity. When a computer is in a sleep state, it is like pausing a DVD player—the computer immediately stops what it’s doing, maintains all open documents and programs, and is ready to start again when you want to resume working.
The project team has developed 3 categories of computers related to power management settings: Normal, Monitor Only, and Public Display. Most users will be in the ‘Normal’ category.

|Category||Monitor Sleeps||Computer Sleeps||Typical Use Members of this Category|
|Normal||15 Minutes (5 for Auxs depts)
||20 Minutes||Normal office use computers|
|Monitor Only||15 Minutes (5 for Auxs depts)
||Never||Computers that people Remote Desktop into, Computers that record/serve data from/to other machines.|
|Public Display *||Never||Never||Kiosks, Instructor stations, computers used to display information to passers-by while no one is actively using them.|
* When appropriate these computers and monitors should be turned off when not in use.
(Macintosh computers are not yet in the scope of this project.)

- National Policy Consensus Center: NPCC rolled out department wide power management settings almost a year ago with no disruptions to users.OIT was able to accommodate our request to exclude one computer from the implementation whose function requires us to keep it operational at all times. The transition went smoothly and was not noticed by staff although they were aware of the changes taking place.
