High Performance Buildings: Data Centers Uninterruptible Power Supplies (UPS)

12/01/2005

The goals for this project included a complete analysis of distribution of UPS design efficiencies, which included the development of a UPS test protocol, and the broad circulation of efficiency findings to the industry through the CEC PIER program, Lawrence Berkeley National Laboratories (LBNL), and other industry and efficiency venues, such as www.efficientpowersupplies.org. Using the efficiency findings and market data, we also estimated the overall energy consumption of UPSs in the United States, especially in the State of California, as well as the potential savings from the use of more efficient units. Finally, we also proposed efficiency levels and a labeling scheme for various types of UPS units as a way to encourage the use of more efficient UPSs.
