The U.S. Department of Energy’s Superior Energy Performance® (SEP™) certifies industrial facilities that implement an energy management system that meets the ISO 50001 global energy management system standard and achieve improved energy performance.
In December 2015, Hilton Worldwide gained the distinction of being the first hospitality company—as well as the first company outside the manufacturing sector—to achieve SEP certification. Verified facility-wide energy performance improvements in three of their U.S. properties ranged from 6.3 percent to 15.85 percent. Remarkably, these additional savings were found in facilities that were already considered to be efficient before SEP and ISO 50001 were implemented.
Lawrence Berkeley National Laboratory (Berkeley Lab) researchers, led by Aimee McKane, have been instrumental in the development of SEP, providing critical expertise in standards, measurement and verification, workforce competency, and program design. This work builds on Ms. McKane’s leadership in the development of ISO 50001.
“This is a perfect example of the benefit of the continual improvement focus from ISO 50001, coupled with the data utilization discipline of SEP,” said McKane. “Hilton Worldwide already had a very effective energy efficiency program. They are to be congratulated for bringing their company to a new level of energy performance.”
Berkeley Lab Research Scientist Dr. Peter Therkelsen is also working with the SEP program, leading and publishing original analyses based on field data from U.S. industrial facilities implementing SEP.
