Water Usage Effectiveness As An Important Data Center Metric
February 2013 - Data Centers
Water Usage Effectiveness (WUE) — has this data center metric caught on? How does it measure water usage effectiveness?
WUE is still a fairly new sustainability metric, a natural extension of PUE (power usage effectiveness), the most used metric related to data center energy efficiency. WUE is simply defined as annual site water usage divided by IT Energy Usage. The units are liters/Kwh.
