Some steps to energy efficiency #1: Assess existing energy

consumption and costs, establish baseline

#2: Pursue highest return for savings first = desktop power management and server consolidation

#3: Take other actions such as w/ printers and office equipment, and consider changing some workstations over to Thin Clients

Server consolidation

7

Server virtualization helped us reduce the number of physical servers andlower energy costs

Other actions

8

Replace desktops (110 watts)w/ Thin Clients (17 watts)

Use power switch timers to turn off printers at night, consolidate ratio of printers to staff, and use default duplex printing on all printers

Additional energy efficiency actions

Purchasing: Electronic Product Environmental

Assessment Tool (EPEAT)Energy Star

Lights: Signage for shutting off the lights when leaving a room

Temp settings: 68 degrees winter, 75 degrees summer

Staff and vendors: education and commitment

Additional certification actions
