(WEB HOST INDUSTRY REVIEW) — The US Environmental Protection Agency (www.epa.gov) revealed this week it is nearing the end of its comprehensive task of creating an Energy Star rating for data centers.
The project was first announced more than a year and a half ago. Last April, EPA revealed the structure of its energy performance rating after 12 months of collecting data on energy use and operations from over 100 data centers of all types and sizes.
The rating system is already available for many types of commercial buildings. EPA scores the building’s energy performance on a scale of 1 to 100 then issues an Energy Star label to buildings in the top 25 percent of those rated.
The organization says it will launch the rating system for data centers in early June. The rating will be based on EPA’s Power Usage Effectiveness, a metric the organization developed to measure data center efficiency.
Despite sharing the same name as the Green Grid’s metric, EPA’s metric is calculated differently than the Green Grid’s PUE because it factors in energy rather than power.
John Pflueger, member of the Green Grid’s board of directors and a technical committee chair for the organization, said the organization was in talks with EPA officials to synchronize both organizations’ PUE metrics.
