Building energy management system in public buildings versus energy efficiency

A systematic and detailed introduction of the energy management system in public buildings is taken. Firstly, the building equipment management operating system, which emphasizes particularly on the development of user interface is developed, aiming at the implement of energy management in public buildings. At the same time, the surveillance function and control function of the subsystems for each energy unit are stressed, and the surveillance and control of the subsystems are combined to make the best interface for daily energy management and energy saving control. Then, the energy management system is constructed from the aspects of energy consumption statistic, equipment runtime statistic, parameter statistic and multifunction alarm to make the energy management system more flexible and scalable so as to improve the energy saving effect. Furthermore, Sub-area computation to the energy consumption is also analyzed. Different kinds of fee charge methods are argued and discussed. Finally, the objectives of building equipment management system and the building energy management system in the existing public buildings are summarized. The success and application of energy management system in public buildings will help to save running cost to a great extent.
