Guiding Principles for Energy Efficiency
In an effort to assist data center operators wishing to assess the energy efficiency of their facilities, eight leading organizations that set or use data center energy efficiency metrics met on January 13, 2010 in Washington, DC. The outcome of the meeting is an agreement to three guiding principles for measuring energy efficiency in data centers at the present time. These guiding principles are meant to help the industry have a common understanding of energy efficiency metrics that can generate dialogue to improve data center efficiencies and reduce energy consumption. Each of the participating organizations has agreed to promote these guiding principals to their members and stakeholders in an effort to bring uniformity to the measurement of data center energy efficiency, while the dialogue continues to advance existing metrics. Additionally, the eight participating organizations created a task force to develop further recommendations based on the agreed upon guiding principles. Below please find a copy of the guiding principles established on January 13, as well as the first set of recommendations from the task force on measuring PUE at dedicated data centers.
Additionally, representatives from the U.S., European Union, and Japan met on February 2, 2010 to identify goals and desired outcomes in developing and applying energy efficiency metrics. The meeting resulted in the following agreement on guiding principles for measuring energy efficiency in data centers.
We hope that these principles will help you in your efforts to improve the efficiency of data centers, and welcome your questions by e-mail to ENERGYSTARdatacenters@icfi.com.
The work on these guiding principles has been part of a greater joint initiative by the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy (DOE) called the National Data Center Energy Efficiency Information Program. The program coordinates a wide variety of activities from the EPA ENERGY STAR program, DOE Industrial Technologies Program Save Energy Now initiative, and the DOE Federal Energy Management Program.
ENERGY STAR Rating for Data Centers
In its 2007 Report to Congress on Server and Data Center Energy Efficiency Opportunities (2.5MB), EPA estimated that the nation’s servers and data centers consumed about 61 billion kilowatt-hours (kWh) in 2006 (1.5 percent of total U.S. electricity consumption) for a total electricity cost of about $4.5 billion. As one of the fastest growing sectors, national energy consumption by servers and data centers could nearly double by 2011 to more than 100 billion kWh, representing a $7.4 billion annual electricity cost. However, there is significant potential for energy efficiency improvements in data centers.
Strategic energy management is the key to controlling energy consumption and operating costs. Use EPA's tools and resources below to help you establish an energy management program that includes benchmarking your data center’s energy performance, making no- and low-cost O&M improvements, and earning recognition for your successes.
Benchmark Your Data Center
Data center operators that want to assess the energy performance of their facilities can benchmark their data centers in Portfolio Manager to receive a 1-to-100 energy performance rating. The tools and resources below provide guidance on how to benchmark a data center.
Earn Recognition for Your Achievements
Join the growing group of organizations honored and recognized by EPA for their outstanding contributions to protecting the environment through superior energy efficiency.
ENERGY STAR Data Center Product Specifications
ENERGY STAR Computer Server Specification Development
EPA has launched the development process for the Version 2.0 specification for Computer Servers. Draft 1 of the specification revision was distributed to stakeholders on April 9, 2010 and EPA has held two stakeholder discussions to solicit feedback. All materials related to this effort are posted to the Version 2.0 specification development page at the link below.
ENERGY STAR Version 2.0 Server Specification Development Page
As part of Version 2.0, EPA will be investigating methods with which to evaluate efficiency of servers while completing actual computing, transitioning the program from the current foundation developed for the Version 1.0 specification. EPA developed the following position paper on the current state of energy benchmarking for servers. This paper was presented on behalf of EPA by the British Computing Society at the 2009 TPC Technical Committee conference in Lyon, France. The original publication is available at SpringerLink .
Draft 1 of the ENERGY STAR Version 2.0 Computer Server specification is posted below along with related files.
EPA Finalized Version 1.0 of the Computer Server specification on May 15, 2009. Partners and other interested parties are encouraged to review materials related to development, and the final specification, at the link below.
