As part of its work, the California Energy Commission operates a Research Development and Demonstration (RD&D) Division, which oversees the Public Interest Energy Research (PIER) Program. The PIER program focuses on a number of energy areas, including Building Efficiency. This research aims to decrease building energy use by developing or improving energy-efficient technologies, strategies, tools, and building performance evaluation methods.
Periodically, PIER will publish informational briefs based on its research, which is often conducted with a variety of organizations with funding from the California Energy Commission’s Public Interest Energy Research (PIER) Program. The briefs are written and prepared by E Source.
PIER recently released a brief on research on the efficiencies of various types of uninterruptible power supplies (UPSs) for data centers under a variety of operating conditions. The study, titled “Uninterruptible Power Supplies: A Data Center Efficiency Opportunity,” also proposed an efficiency label for UPSs and estimated the current energy use of the existing stock of UPSs and the potential savings if efficiency standards were in place.
Collaborators on the project included Lawrence Berkeley National Laboratory and its subcontractors, EPRI Solutions, and Ecos Consulting.
