The Green Grid And Global Taskforce For Data Center Efficiency Reach Agreement
The Green Grid and a global taskforce created to harmonize metrics and measurement protocols for key energy efficiency metrics, have announced agreement on measurement guidelines and next steps for three new efficiency metrics. The taskforce reached consensus on the use of the Green Energy Coefficient (GEC), Energy Reuse Factor (ERF) and Carbon Usage Effectiveness (CUE) metrics. Details of their conclusions and recommendations for use of each metric are available in a memo titled, “Harmonizing Global Metrics for Data Center Energy Efficiency.”
In February 2011, the taskforce reached agreement on specific measurement protocols for the Power Usage Effectiveness (PUE) metric, developed by The Green Grid. Made up of the U.S. Department of Energy’s Advanced Manufacturing Office and Federal Energy Management Programs; the U.S. Environmental Protection Agency’s ENERGY STAR Program; the European Commission Joint Research Center Data Centers Code of Conduct, Japan’s Ministry of Economy, Trade and Industry; Japan’s Green IT Promotion Council; and The Green Grid, the taskforce intends to continue collaboration as an ongoing effort to improve data center energy and Greenhouse Gas (GHG) emission efficiencies.
