The U.S. Environmental Protection Agency (EPA) has released revised Version 1.0 Energy Star program requirements for UPSs. The requirements consist of revised eligibility criteria (marked Rev. Jul-2012), and the final partner commitments and test method previously released in May.
The revised eligibility criteria include a clarification to the requirements for Diesel Rotary UPSs (DRUPS), requiring the demonstration of compliance with the Clean Air Act for models sold in the United States.
