“The Green Grid is working with organizations around the world to develop a clear and well-defined language for the way we communicate about energy efficiency metrics, which will give us a common measuring stick for all data centers regardless of their location,” said Tom Brey, an IBM employee who is secretary of The Green Grid, in a statement.
PUE, which was developed by the Green Grid, divides the total energy consumed by a data center by the amount of energy used to power the IT equipment. It has emerged as the most popular metric for measuring data center efficiency, and some large companies, notably Microsoft and Google, have been publishing PUE numbers as a way to show off the efficiency of their newest facilities.
“A global task force with representatives from each of the above mentioned organizations will continue to move this initiative forward and reconvene later this year to evaluate progress,” the Green Grid says in the statement.
In January representatives from the EPA met with several data center industry groups from the U.S., including 7×24 Exchange and ASHRAE (The American Society of Heating, Refrigerating and Air-Conditioning Engineers).
Rising energy costs and the amount of powerful IT equipment that has been added to data centers in recent years has made them a cost center on the radar of senior executives.
