The Green Grid Association, together with The Data Center Metrics Coordination Task Force, 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.
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 intends to continue collaborating
in the years ahead to ensure that data center resource efficiency and
productivity is delivered as consistently as possible across regions. The Green
Grid has recently announced additional metrics to complement PUE, including carbon
usage effectiveness (CUE) and water usage effectiveness (WUE), designed to help
data center operators assess the sustainability of their data centers.
