AOL has just earned Energy Star certifications for its Virginia data centers, Dulles and Manassas, the only two data centers in the state with this distinction.

This accomplishment means the buildings perform in the top 25% nationwide for energy efficiency and they meet strict energy efficiency performance levels set by the U.S. Environmental Protection Agency and Department of Energy under the Energy Star program.

Commercial buildings that earn EPA's Energy Star certification use an average of 35% less energy than typical buildings and release 35% less carbon dioxide into the atmosphere. Given the power density requirements specific to data centers, an organization-wide commitment to energy conservation and efficiency is required to successfully earn the Energy Star certification. Earlier this year, AOL also won Uptime Institute awards for data center and IT efficiency.

Here are some reasons that AOL received an Energy Star Certification:

· AOL improved its data floor monitoring and chiller efficiency to better match the required cooling of the data floor with the computer room AC units; this measurement system allowed some of the AC units to be turned off at low-load times
· At the Dulles Tech Center, AOL retrofit the HVAC system with variable frequency drive motors, which resulted in increased energy efficiency
· Across the suite of Dulles campus buildings and technology centers, these cost effective and energy efficient improvements have saved AOL more than $7 million in energy costs
