Data Centers Can Now Earn Energy Star Label
June 2010 - Data Centers
Stand-alone data centers and buildings that house large data centers can now earn the Energy Star label. To earn the label, data centers must be in the top 25 percent of their peers in energy efficiency according to the U.S. Environmental Protection Agency’s (EPA) energy performance scale.
EPA uses the Power Usage Effectiveness (PUE) metric to determine whether a data center qualifies for the Energy Star label. Before being awarded the Energy Star, a licensed professional must independently verify the energy performance of these buildings.
Data centers account for 1.5 percent of total U.S. electricity consumption at a cost of $4.5 billion annually, an amount that is expected to almost double over the next five years.
Based on the latest available data, improving the energy efficiency of America’s data centers by just 10 percent would save more than 6 billion kilowatt-hours each year, enough to power more than 350,000 homes and save more than $450 million annually.
