Demand Based Optimization - A New Paradigm for Optimizing Laboratory Ventilation for Energy Savings and Safety at EPA's Research Triangle Park Facility.

Dan Amon and James White, U.S. Environmental Protection Agency
Thomas C. Smith, Exposure Control Technologies, Inc.

This presentation will discuss a process to access the current ventilation requirements and then optimize the ventilation systems to meet that demand. It will tell a story of how EPA used Labs21 principles, best practices, and benchmarking to conceptualize, program, pilot, and finally implement a major recommissioning of its flagship Research Triangle Park (RTP) facility. Starting with the basic flow concepts which kicked-off the project, then outlining the highly complex testing and verification procedures piloted and implemented to prove accuracy, repeatability and reliability of the laboratory control systems, the presentation will discuss how RTP's facility managers are using the tools they obtained at the conclusion of this project to continuously commission and diagnose their laboratory ventilation and control systems.

Labs21 Connection:

This may be the first comprehensive laboratory controls recommisioning project to focus on demand-based optimization. Leveraging standard ASHRAE testing methods, and incorporating standard commissioning practices into a potential new standard for laboratory certification and performance.


Dan Amon has for the past 21 years led a distinguished career in engineering and construction. He has a wide range of experience in mechanical design and construction, including: semiconductor facilities, pharmaceutical facilities, and other high technology industries. He received his undergraduate degree in Structural Engineering from the University of Minnesota Institute of Technology, and went on to earn a Master's degree in Engineering and Management from Stanford University.
