Monitoring and Fault Diagnosis in Smart Buildings

In recent years, there has been significant interest in energy efficiency of smart buildings. The most energy consuming subsystem in a smart building is the heating, ventilating and air-conditioning (HVAC) system, which is estimated to utilize approximately 20% of the total energy consumption in the USA. The smooth and healthy operation of the HVAC system is of significant importance in large-scale buildings for maintaining high indoor air quality for the occupants and sensitive equipment. The objective of this presentation is to develop a model-based distributed monitoring scheme with emphasis on the fault detection and isolation in multi-zone HVAC systems. The proposed methodology is developed in a distributed framework, considering a multi-zone HVAC system as a set of interconnected nonlinear subsystems. A dedicated local fault diagnosis agent is designed for each subsystem, while it may exchange information with neighboring local agents. Distributed fault detection is conducted using robust analytical redundancy relations of estimation-based residuals and adaptive thresholds. The performance of the proposed methodology is analyzed with respect to robustness, fault detectability, and isolability. Simulation results are used for illustrating the effectiveness of the proposed methodology.

Marios M. Polycarpou is a Professor of Electrical and Computer Engineering and the Director of the KIOS Research Center for Intelligent Systems and Networks at the University of Cyprus. He received the B.A. degree in Computer Science and the B.Sc. degree in Electrical Engineering both from Rice University, Houston, TX, USA in 1987, and the M.S. and Ph.D. degrees in Electrical Engineering from the University of Southern California, Los Angeles, CA, in 1989 and 1992 respectively. Prior to joining the University of Cyprus as founding Department Chair in 2001, he was Professor of Electrical and Computer Engineering and Computer Science at the University of Cincinnati, Ohio, USA. His teaching and research interests are in intelligent systems and networks, adaptive and cooperative control systems, computational intelligence, fault diagnosis and distributed agents. Dr. Polycarpou has published more than 250 articles in refereed journals, edited books and refereed conference proceedings, and co-authored 6 books. He is also the holder of 6 patents.

Prof. Polycarpou is a Fellow of the IEEE and and served as the President of the IEEE Computational Intelligence Society between Jan. 2012 – Dec. 2013. He has served as the Editor-in-Chief of the IEEE Transactions on Neural Networks and Learning Systems between 2004-2010. In 2014, Dr. Polycarpou was the recipient of the Best Paper Award for the journal Building and Environment (Elsevier). He participated in more than 60 research projects/grants, funded by several agencies and industry in Europe and the United States. In 2011, Prof. Polycarpou was awarded the prestigious European Research Council (ERC) Advanced Grant.
