About Us

Advanced Building Performance, Inc (ABP) was founded in 2003 by Paul Tseng, with a single mission: to provide cost effective solutions that deliver sustainable, high performance buildings for our clients. ABP has grown from a sole practitioner into a mature Certified Commissioning Firm (CCF) with more than 350 completed projects. Our award-winning commissioning and sustainable engineering consulting services for green buildings and LEED projects are based on a comprehensive understanding of building systems and technologies, the construction process, and commissioning protocols. ABP had the privilege to commission some of the very first projects in the history of LEED.


At ABP, we are passionate about the environment, and focus on delivering excellence to the clients we serve. Our staff offer a unique combination of technical knowledge and strong management skills that give our clients practical solutions for their most challenging building problems. We work in our communities, to shape the future of sustainable design and actively contribute to leading industry organizations such as the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE), Building Commissioning Association (BCxA), and the US Green Building Council (USGBC).
