Paul C. Tseng

Founder, Commissioning Authority

Paul, a nationally recognized authority on commissioning, is a passionate man known in the engineering community for many “firsts” in the advancement of high performance buildings and integrated design. He has been engaged in commissioning since the beginning stages of the practice, having served on the Guidelines Committee for ASHRAE Guideline 0 on the Commissioning Process and on the Guideline 1 for the HVAC commissioning process.

Paul commissioned some of the very first LEED certified buildings in history, including many prominent landmarks. His impressive project profile includes the first certified convention center in North America and the largest green building in the world, The David L. Lawrence Convention in Pennsylvania. Additionally, he served the Commissioning Authority for the LEED Platinum Certified U.S. Green Building Council Headquarters project in Washington, DC, the LEED Gold Certified Seven World Trade Center project in New York City, and the first LEED Gold certified building in Beijing China, the Prosper Center.

Paul’s passion for building design has spanned his 45 year career. Known as an effective team leader, program innovator and manager, he has worked as a design consultant and energy efficiency expert for industrial, governmental and institutional clients. As a result of his steadfast commitment to the building industry, Paul has been honored with over a dozen prominent industry awards. In 2005, he received the highest honor awarded in the commissioning industry, the prestigious Benner Award for his contribution to the commissioning profession and the growth of the industry. Additionally, he twice received the Energy Manager of the Year Award, as well as the U.S. Green Building Council’s Member of the Year Award. He is also a widely published author and has served on the editorial board for HPAC Engineering Magazine.

Paul’s commitment to the building industry extends beyond ABP. Since 1992, he has been a professor of commissioning and LEED certification at the University of Wisconsin-Madison School of Engineering Graduate School’s Professional Development Program. He also taught at George Washington University’s Graduate School of Engineering. Furthermore, he has provided significant pro-bono professional services to non-profits and other institutions and associations.

Prior to founding ABP, Paul served as the Chief Facilities Engineer at Montgomery County Government. In this role, he initiated and implemented a nationally recognized total building commissioning program. He also served as Northeast Regional Director for Energy Consulting Services at CH2M Hill.

Over the years, Paul has found time to develop another passion for sampling Chinese food restaurants in the Washington Metropolitan area. He has dined at almost all of the local area restaurants and he has developed personal relationships with many of the owners. Should you need a restaurant recommendation, Paul is the restaurant citric you should consult.
