EPA to launch Energy Star ratings for Data Center by June 2010; Europe, China and India are in as well

EPA’s Portfolio Manager will also be amended so you can rate your Data Center yourself.
The EPA already rates the energy efficiency of 18 types of buildings, including offices and hospitals. The main criteria for those are floor space and hours of operation, but it needed a different system for data centers.
The measurement will be based largely on PUE (power unit efficiency), which measures the total power supplied to a data center, divided by the amount that actually reaches IT equipment, rather than being lost to cooling systems and inefficient power supplies.
The EPA will also take into account the energy output from the UPS systems. That means that while data centers with good PUE scores will tend to get higher rankings, PUE will not be the only factor, Sullivan said.
The program is likely to stir some debate. Some attendees at the Green Grid event were surprised other criteria won’t be included, such as whether a data center is located in a cool or warm climate, or the level of redundancy it provides.
“You have to take the environment into account because it’s easier to have a low PUE score if you’re in a cold climate,” said Don Klein, vice president of marketing and business development with Modius, which makes tools for measuring data-center energy use.
