Power Usage Effectiveness (PUE) has become the industry-preferred metric for measuring infrastructure energy efficiency for data centers. The PUE metric is an end-user tool that helps boost energy efficiency in data center operations. Since its original publication, PUE has been globally adopted by the industry. Over the past years, The Green Grid has continued to refine the metric measurement methodology with collaborative industry feedback. This collective work has been brought together here to simplify the absorption and use of the PUE metric.

To produce this document, The Green Grid consolidated all its previously published material related to PUE and included new material as well. This document supersedes prior white papers and consolidates all things that The Green Grid has developed and published relating to PUE. As such, this document is recommended by The Green Grid to those implementing, using, and reporting PUE. Quick access to various levels of information is provided via the links embedded throughout the document. This document allows executives to gain a high level of understanding of the concepts surrounding PUE, while providing in-depth application knowledge and resources to those implementing and reporting data center metrics.

The definition and measurement guidelines included in this book have been harmonized globally, with a primary focus on energy.
