Research summary
AI-generated

Jie Cai's research focuses on making building heating, cooling, and energy storage systems smarter and more efficient, particularly heat pumps, refrigeration equipment, and phase-change material (a substance that stores/releases heat as it changes state) energy storage integrated into buildings. Work involves developing control strategies and physics-based or data-driven models to improve system performance, stability, and flexibility, including how buildings can respond to demand from the electric grid. Some recent publications also touch on unrelated topics such as machine learning models and medical sleep-disorder diagnostics, suggesting collaborations outside the core building-systems focus.
