The U.S. Environmental Protection Agency announced this week that data centers can now earn an Energy Star label by demonstrating top-tier energy efficiency.

The federal agency said to earn the Energy Star label, data centers must be in the top 25% of their peers as measured utilizing the Power Usage Effectiveness metric. The Power Usage Effectiveness metric, or PUE, was developed by the Green Grid, a data center energy group.

In order to be awarded the label, which is seen on such appliances as refrigerators and washing machines, a licensed professional must independently verify the performance of the facility and sign and seal a document that is filed with the EPA.

At a conference in Florida this week, Alexandra Sullivan, the technical development manager for the Energy Star program, said the main goal of the initiative is to provide a simple, easily communicated symbol to provide motivation for energy savings in data centers.

The organization noted that improving the efficiency of data centers by 10% could result in the reduction of more than 6 billion kilowatt-hours of electricity in the U.S. That would be equivalent to the energy needed to power more than 350,000 homes and result in more than $450 million in savings per year.
