Building operations account for approximately 40% of energy consumption and carbon emissions in the United States, and 75% of peak electrical demand. Building HVAC systems are complex networks, designed to meet occupant needs for thermal comfort and air quality. These interconnected systems increase in complexity with the on-site energy generation systems to meet the goal of Net-Zero Energy Buildings. Improving building efficiency has the potential for significant economic and environmental impact, but requires control strategies that address the underlying nonlinear, coupled, constrained, and multi-time scale dynamics that characterize these systems. In this seminar, we will discuss some of the challenges and opportunities associated designing with building HVAC system controls, with a specific discussion of control architectures that lead to fundamental improvements in performance. This includes improved component level control of HVAC subsystems, as well as coordinated supervisory control algorithms for entire buildings. A distributed predictive control architecture will be proposed for coordinating and optimizing system level efficiency, while retaining the modularity essential for large scale deployment.

Biography of Bryan Rasmussen:
Bryan Rasmussen is currently an Associate Professor of Mechanical Engineering at Texas A&M University. Dr. Rasmussen’s research focuses on dynamic modeling and control of building energy systems. He is also the director of the Industrial Assessment Center, a US Dept. of Energy program that trains students to conduct energy audits for industrial manufacturing facilities. He was awarded the NSF CAREER and the ASHRAE Young Investigator awards for research, and is the recipient of various teaching awards. Dr. Rasmussen received his B.S. degree in Mechanical and Aerospace Engineering from Utah State University in 2000, and received M.S. and Ph.D. degrees in Mechanical Engineering from the University of Illinois at Urbana-Champaign in 2002 and 2005.
