Green Grid Collaboration Completes Energy Efficiency Measurement Recommendations
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.
