Lead Commissioning Authority
James pioneered Energy Performance Engineering, LLC (EPE) in 2005 with years of experience in mechanical systems design, facilities engineering, control contracting, and Commissioning. James assists clients with integrating performance and energy efficiency into building systems to meet the needs of increasingly complex and intelligent building control networks. James is a great asset because he has managed mechanical (HVAC) and direct digital controls systems Page 2 of 3 serving a 280,000sf advanced technology manufacturing facility and central utility plant. He has managed numerous controls and Commissioning projects that included carrying out Engineering Studies, making project schedules, providing cost estimates, reviewing construction drawings, and writing specifications.
James Jen was born and raised in Taipei, Taiwan. Some of his early interests included sketching cartoons. In high school he excelled in drafting and remembers how time would pass quickly when he was engaged in his projects. His favorite sport was basketball. He was inspired by the NBA players in the United States, hoping someday he could be in the league. “I didn’t really have the height, but I was small, fast and very competitive,” jokes Jen. After recurring ankle injuries, Jen was forced to stop playing basketball.
In 1976, James attended the China Maritime College. Prior to graduating, he needed to fulfill his school’s requirement for one year on a Taiwanese commercial ship traveling the world as a Marine Engineer. After graduating he spent two years in mandatory military service as a Navy officer. While in the Navy, he coached two winning basketball teams.
James and Elee met in 1981 at OSU through a campus Christian fellowship. They were amazed at the number of similarities in their backgrounds and felt close from the beginning. The couple wed in 1985 and moved to Los Angeles, where James worked for McDonnell Douglas.
In 1994, James was hired by Seltec Silicone and moved the family back to Oregon. He worked for various mechanical and design firms since 2000. In 2005, James and Elee started Energy Performance Engineering. The company specializes in building commissioning, a service that ensures new buildings will operate as planned. Elee has been the Marketing Manager for the company and they’ve seen the business grow and become more profitable since 2010.
In 1980, he was out of the military and began his Engineering studies at Oregon State University.

EPE provided a great resource for the commissioning process during this process. It is clear that Jimmy has a deep understanding of the project requirements and that he was working to drive the project to a successful completion. As discrepancies arose, Jimmy provided insight based on his knowledge and helped all parties come to the conclusion that was best for the project. The testing plans developed by EPE were very thorough and they allowed for us to have a successful testing phase before building delivery.
