Back to Best Practices
General
- Power off electronic devices when not in use (i.e., fans, typewriters, calculators, copiers, etc).
- Do not turn on electronic devices until you will actually be using them.
- Avoid using the switch on a power strip to turn on all your equipment simultaneously.
- Purchase only "Energy Star" compliant devices.
Computers
- Power off computer equipment during non-business hours.
- Use wake-on-lan technology to apply security patches during non-business hours. For technical setup instructions visit: http://www.vpaf.uni.edu/tss/energy/documents/power_mgt_wol.pdf
- Configure your computer to go into low-power or sleep mode after 20 minutes of inactivity.
- Consider powering down the hard drive after inactivity.
- Purchasing Suggestion:
- A computer with a low-profile or "small form factor" chassis generally consumes less energy than a mini-tower or full-sized desktop machine. You may not need the larger machines that requires more robust power supplies to accommodate expansion options such as additional drives or plug-in cards. Laptop computers, although more expensive, are even more energy efficient.
Monitors
- Do not use screen savers.
- Configure your monitor to go to sleep (blank screen) after 20 minutes of inactivity.
- Power off the monitor when not in use.
- Purchasing Suggestion:
- Flat-panel (LCD) displays, although more expensive than conventional (CRT) monitors, are far more energy efficient. They are more space efficient as well.
- Buy a monitor only as large as you really need. Larger monitors typically use more energy than smaller devices.
Peripherals (including printers)
- Power off peripherals during non-business hours.
- Configure peripherals to operate in power savings mode (particularly printers).
- Share peripherals within the office. Examples:
- Use networked printers, reducing the use of individual printers.
- Install a departmental scanning station.
- Don't turn on your printer, scanner, etc., until ready to use.
- Purchasing Suggestion:
- Consider purchasing "multifunctional" devices that combine technologies (print, copy, fax, scan, etc) in a single device.
- Consider purchasing a printer with a duplex capability to allow printing on both sides of a sheet of paper.
Servers
- Turn off monitors when not in use.
- When possible, consolidate multiple servers to a single, higher-performance device.
- When possible, utilize virtual machine technology to reduce the number of physical devices necessary.
- Locate server technology in data centers built to manage heating and cooling in an efficient manner.
- Purchasing Suggestion:
- Consider purchasing hardware with built-in power management features (i.e., Dell PowerEdge PowerNow!) that adjust processor power states, voltage and clocking frequencies depending on workload.
- Consider utilizing blade technology
Paper
- Review your document on screen instead of printing a draft. Reduce wasted printing by using the "print preview" option to find errors before printing.
- Do not use a printer for multiple copies. Copiers are more efficient for this purpose and the cost is less.
- Avoid printing out copies of email unless necessary.
- Reduce paper use by printing on both sides.
- Rather than printing and filing documents in a cabinet, file documents electronically for future access.
- Use email instead of faxes or send a fax directly from a computer to eliminate the need for a printed copy.
- When possible, use smaller font sizes to save paper.
- Disable the power-on test page print for those devices that include this feature.
- Prior to recycling paper, set it aside for use as scrap paper.
- Buy and use recycled paper.
- When possible, circulate printed materials instead of making printed copies for each person.
