This White Paper explores some of the more common Power Usage Effectiveness (PUE) calculation mistakes and myths while demonstrating their impact on PUE values calculated for a specific data center facility design project.
It is unfortunate that an acronym as widely used in the data center industry as "PUE" is most often misused. Few will argue that energy efficiency is an important metric in the operational analysis of a data center facility. However, Power Usage Effectiveness, commonly referred to as PUE has become more of a marketing tool than an energy efficiency metric. This exploitation is particularly blatant in the marketing of new data center design "innovations". This paper explores some of the more common PUE calculation mistakes and myths while demonstrating their impact on PUE values calculated for a specific data center facility design project.
