by Rebecca Walker — May 18, 2011—The Green Grid Association, a leading voice in the IT industry for advancing resource efficiency in data centers and business computing ecosystems, together with The Data Center Metrics Coordination Taskforce, has delivered its latest recommendations for energy efficiency measurement and reporting.
The new report, titled Recommendations for Measuring and Reporting Overall Data Center Efficiency: Version 2 — Measuring PUE at Data Centers completes the guidelines for applying the Power Usage Effectiveness (PUE) metric, created and promoted by The Green Grid. The new information includes specific recommendations for how to measure and calculate PUE in mixed-use data center facilities and introduces a condenser water source energy weighting factor.
PUE determines the amount of energy used by a data center facility and the IT gear inside of it. A detailed explanation of PUE can be found on The Green Grid’s Web site.
Alignment on these methodologies across the industry will lead to consistent and repeatable measurement strategies that allow data center operators to monitor and improve the energy efficiency when operating their existing data centers, or when designing new facilities. The task force’s latest report represents the combined decision-making from 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.
