PUE, wereldwijd ondersteund
Zoals ik eerder melde in Werken aan eenheid rond PUE.., is men bezig om een breed ondersteunde omschrijving van PUE vast te stellen.
Deze is recent uitgebracht:
On January 13, 2010, eight leading organizations that set or use data center energy efficiency metrics, including the 7×24 Exchange, ASHRAE, The Green Grid, Silicon Valley Leadership Group, U.S. Department of Energy’s Save Energy Now and Federal Energy Management Programs, U.S. Environmental Protection Agency’s ENERGY STAR Program, U.S. Green Building Council, and Uptime Institute, met to discuss these metrics for data centers and formed a task force to further define these measurements. This task force, which has met regularly since the initial summit, has prepared the attachedRecommendations for Measuring and Reporting Overall Data Center Efficiency. The goal of this document is to recommend a consistent and repeatable measurement strategy that allows data center operators to monitor and improve the energy efficiency of their facilities. A consistent measurement approach will facilitate communication of Power Usage Effectiveness (PUE), the recommended energy efficiency metric from the agreed upon guiding principles, among data center owners and operators. More information about the guiding principles from the January meeting can be found here.
The attached document addresses how to measure PUE in dedicated data centers. The task force will continue to meet to develop recommendations for how to measure PUE for data centers in larger mixed-use facilities.
We hope that these recommendations help you understand how to measure and publish overall data center infrastructure energy efficiency, and we welcome any questions by e-mail to ENERGYSTARdatacenters@icfi.com.
Dit document geeft een mooie basis voor het werk van NEN en CENELEC voor de respectievelijk Nederlandse en Europese datacenter standaarden.
Mijn dank aan DatacenterPulse collega Tim Crawford, voor zijn inzet en werk op dit vlak!
