Adaptive Optimization Method for Energy Conservation in HVAC Systems

As a way to reduce the energy consumption in the building's HVAC system, a practical method for optimal control has been developed. Since the proposed method identifies the approximated objective function with the past operational data, it automatically optimizes the settings in accordance with the change in the outside environment and building operation. As the result of a validation with an actual hotel building, we were able to demonstrate that the proposed method realized energy conservation by increasing the chilled water temperature appropriately.
