Power usage effectiveness compares the total electricity a facility draws to the electricity that reaches the computing equipment itself: . The Green Grid, the industry consortium that introduced the metric in 2007 and later consolidated its guidance into a single reference document, defines it plainly: “PUE for a dedicated building is the total facility energy divided by the IT equipment energy. PUE is an end-user metric used to help improve energy efficiency in data center operations” [ 5 ] . An ideal value is 1.0, meaning every watt drawn by the site reaches the computing load;…
