Biography
Dr. Wonjun Choi is an Associate Professor at the School of Architecture, Chonnam National University, and leads the Building Energy Technology laboratory (betlab). His research is focused on the design and control of building renewable energy systems, with a particular emphasis on probabilistic system design and control, accounting for uncertainties associated with individual buildings, energy systems, and the uncontrollable environment. Examples of his work include the development of a renewable energy network system that combines various renewable energy sources, probabilistic inverse problems related to energy system design and control, exergy analyses for the built environment, and the development of interpretable AI models for model predictive control of renewable energy systems.
