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

Savings from DPM software• Community IT Innovators:
40% reduction in PC energy consumption
• Bread for the World: 30% reduction in PC energy consumption
• Howard County (MD) Community College: $50k savings per year
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
10
Established Green policiesRevamped Green MetricsChanged to 100% recycled
paper productsAfter certification, decided
to switch to green cleaning services

Some ways we can help• Green IT audit• IT energy usage measurement
and assessment• Desktop power
management• Server virtualization• Recycling computing
equipment • Other services
