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.
These revisions were proposed in a memo to stakeholders distributed on June 25; this proposal was further revised based on stakeholder comments, resulting in the version being distributed. EPA thanks stakeholders for their feedback.
