According to ASHRAE, power usage effectiveness (PUE) has become the globally adopted metric for measuring the energy efficiency of data centers. In response to this demand, ASHRAE and The Green Grid have published “PUE: A Comprehensive Examination of the Metric.”
This is the 11th book in the Datacom Series of publications from ASHRAE Technical Committee (TC) 9.9, Mission Critical Facilities, Data Centers, Technology Spaces, and Electronic Equipment. ASHRAE TC 9.9 collaborated with The Green Grid on the book.
“Our primary goal is to provide the data center industry with unbiased, vendor neutral data in an understandable and actionable way and this latest publication on the PUE metric does exactly that,” said Don Beaty, publication subcommittee chair of TC 9.9. “We want to ensure that data center designers, owners, and operators have access to information that enables them to make informed and educated decisions based on their business needs and value systems.”
For this book, all previously published material related to PUE was consolidated and augmented with new material. The content includes detailed information on procedures for calculating, reporting, and analyzing PUE measurements, plus quick references to other resources in print and online. ASHRAE officials claim the intention is that a broad audience can easily grasp the guidance offered.
"Data centers are complex systems for which power and cooling remain key issues facing IT organizations today,” said John Tuccillo, chairman of the board for The Green Grid Association. “The Green Grid Association's PUE metric has been instrumental in helping data center owners and operators better understand and improve the energy efficiency of their existing data centers, as well as helping them make better decisions on new data center deployments.”
