  1. 1. Energy Star labels and Information Technology<br />Rob JonesEnvironmental Manager CSC UK<br />May 2011<br />
  2. 2. Energy Star<br />Voluntary – appliance specific – energy labelling scheme.<br />Sets minimum energy efficiency standards by item type.<br />Created in 1991 partnership with US EPA and Dept of energy.<br />1992 first accredited products including PCs and monitors.<br />Only covers energy in the in use phase of the lifecycle.<br />2003 EU agreement for office equipment only.<br />Quoted in UK Govt buying standards.<br />Standards updated regularly .<br />www.eu-energystar.org<br />
  3. 3. Energy Star Web functionality<br />
  4. 4. Energy Star Web functionality<br />
  5. 5. What does V5.0 Energy Star really mean?<br />Labelled electronically or physically.<br />User information requirements.<br />Power management.<br />Item must fit Energy Star definition (ie Desk top computer, thin client, workstation etc)<br />Internal PSU 85% efficiency at 50% of rated output 82% at 20 and 100%<br />External PSU Must meet Energy star spec for external PSU (separate)<br />TEC <br />Category A ≤ 148 kWh<br />Category B ≤ 175 kWh<br />Category C≤ 209 kWh<br />Category D≤ 234 kWh<br />+ allowances for additional memory and HDD’s<br />
  6. 6. Examples of variance in accredited products<br />ETEC = Min kWh pa ((1.4 x 0.55) + (3 x 0.05) + (35.3 x 0.4)) x (8760/1000)<br />Best to worst difference £12.54 pa<br />With power management disabled (by employee?) best ETEC changes from 131.6 to 309.2<br />Running cost and carbon impact increase by an additional 134%<br />
  7. 7. Energy Star – A cautionary tale<br />“US agencies toughen up Energy Star standards after embarrassing lapses<br />Undercover investigators gain Energy Star accreditation for phony gas-powered alarm clock “<br />Business Green. 16 Apr 2010 <br />
  8. 8. Limitations of Energy Star Labelling.<br />Manufacturers able to submit own data for accreditation.<br />May be substantial variation in compliant product performance.<br />Values are comparative and do not take applications into account.<br />No account of production and supply impact<br />How you manage usage is as important<br />Configuration may disable power management features.<br />
  9. 9. EPEAT – A more comprehensive standard.<br />www.epeat.net<br /><ul><li>Graded performance bronze / silver / gold.

  17. 17. Managing usage – Example 1 CSC deployment of NightWatchman ®<br />The most energy efficient and energy star rated PC’s and servers can waste power if not managed correctly.<br />CSC have employed NightWatchman ® across 50,000 PC’s with 40% reduction in desktop energy consumption.<br />CSC have trialled NightWatchman ® Server edition on 68 Servers.<br />In summary, the pilot has been a positive experience for CSC, with results that provide insight into all areas of data center management. “If asked what the pilot has taught us,” says John Glowacki Jr., Corporate Vice President and Chief Technology Officer, CSC , it would be that we run a tight ship and manage our server fleet well; but also that even a well managed fleet can find efficiency improvements with Server Edition.” <br />
  18. 18. Managing usage – Example 2 Print Rationalisation<br />At quoted monthly volumes existing devices used a combined<br />total of 296.20 kWh of electricity per month.<br />59.22 kWh printing.<br />163.95 kWh in stand by.<br />73.02 kWh out of hours.<br />At quoted monthly volumes the rationalised solution uses a combined<br />total of 52.06 kWh of electricity per month.<br />33.01 kWh printing.<br />17.51 kWh in stand by.<br />1.46 kWh Out of hours.<br />
