How is PUE measured?

Power usage effectiveness (PUE) is a metric used to determine the energy efficiency of a data center. PUE is determined by dividing the amount of power entering a data center by the power used to run the computer infrastructure within it.

Which green IT consortium came up with the PUE benchmark?

It was developed by The Green Grid Association, a non-profit, open industry consortium of end users, policy makers, technology providers, facility architects, and utility companies working to improve the resource efficiency of information technology and data centers throughout the world.

What is the ideal PUE?

An ideal PUE is 1.0. Anything that isn’t considered a computing device in a data center (i.e. lighting, cooling, etc.) falls into the category of facility energy consumption.

How is DCiE calculated?

DCiE, which is expressed as a percentage, is calculated by dividing IT equipment power by total facility power.

When did the Green Grid publish Pue metrics?

In 2007, The Green Grid published two “self-help” data center energy efficiency metrics for end users: power usage effectiveness (PUE™) and its inverse, data center infrastructure efficiency (DCiE™). Since the original publications, PUE has surpassed DCiE in industry adoption.

Where can I buy Pue by the Green Grid?

Guests can purchase PUE: A Comprehensive Examination of the Metric [link to http://www.techstreet.com/ashrae/products/1869497?ashrae_auth_token=] through the ASHRAE bookstore in partnership with The Green Grid. This book supersedes all prior white papers and consolidates previously published content that The Green Grid has developed related to PUE.

What is the Green Grid Association ( TGG )?

The Green Grid Association (TGG) works to improve the resource efficiency of information technology (IT) and data centers throughout the world. In 2007, The Green Grid published two “self-help” data center energy efficiency metrics for end users: power usage effectiveness (PUE™) and its inverse, data center infrastructure efficiency (DCiE™).

What does Pue stand for in data center?

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.
