HVAC systems constitute ∼ 40% of energy in commercial buildings, and faults in HVAC account for 5% to 20% of its energy consumption. Typically, HVAC in modern buildings are managed using Building Managing Systems (BMS), and fault detection is one of the essential services provided by BMS to keep HVAC operational. We study the fault management practices followed in real commercial buildings, and...

Thesis Committee and providing invaluable suggestions and feedback on my research. I thank members of Intelligent System Laboratory who have worked with me. Special thanks to my colleagues: Yaohui Zeng, who worked with me on HVAC project and introduced me to this research area; Dr. Xiupeng Wei, who worked with me on wastewater project and shared his research experiences with me; Guanglin Xu, wh...

The heating, ventilation, and air-conditioning (HVAC) system account for substantial energy use in buildings, whereas a large group of occupants is still not actually feeling comfortable staying inside. This poses the issue developing energy-efficient HVAC control, i.e., reduce (cost) while simultaneously enhancing human comfort. brief pursues objective studies stochastic optimal control subjec...

Most studies about the control, automation, optimization and supervision of building HVAC systems concentrate on steady-state regime, i.e., when equipment is already working at its setpoints. The originality current work consists proposing multi-HVAC from start-up until they reach setpoint, making transition to steady state-based strategies smooth. proposed approach works transient regime optim...

Researchers have extensively explored predictive control strategies for controlling heating, ventilation, and air conditioning (HVAC) units in commercial buildings. Predictive control strategies, however, critically rely on weather and occupancy forecasts. Existing state-of-the-art building simulators are incapable of analysing the in uence of prediction errors (in weather and occupancy) on HVA...
