为了降低建筑暖通空调系统的能耗，开发了一种实用的优化控制方法。由于所提出的方法用过去的运行数据识别近似的目标函数，因此它会根据外部环境和建筑运行的变化自动优化设置。通过对实际酒店建筑的验证，我们能够证明，所提出的方法通过适当提高冷冻水温度实现了节能。引文:内华达州拉斯维加斯ASHRAE会议论文

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.
