Energy Consumption Monitoring System Of Large Public Buildings In Xi'an And Its Energy Saving Potential

With the rise of the total number of China's construction and people's requirements for living comfortment,the problem of building energy control has became more and more prominent in China. Amid building energy consumption, large public buildings drew many attentions with its huge energy consumption per unit area. The situation of energy wasting is serious in large public buildings. And there is a huge saving space. Energy consumption reduction, not only can help companies reduce budget and improve competitiveness, but also can development the sustainable development of the economic and society. Unfortunately, due to the lack of systematic, reliable and accurate building energy consumption data, energy-efficient design of new buildings and energy saving reconstrction for old buildings are the lack support and guidance of data. The energy consumption monitoring system for large public building described in this article,is designed to build a large statistics platform for terminal energy consumption in a building. analysis the specific characteristics of building energy consumption , provide a scientific basis for the implementation of energy saving measures and policies.(1)This paper analyzed and compared a number of previous studies of large public consumption monitoring system . Based on these researches, Proposed another kind of large-scale public power monitoring system which is based on the ZigBee wireless sensor networks. With the new wireless network technology, we can solve the problems during the construction of energy monitoring system. Eliminating the integrated wiring, the construct process will not infact the normal use of the building. (2)In this paper, large public building energy consumption monitoring system has been analyzed systematically. The system has been divided into for four subsystems,which are energy information collection, transmission, storage and dissemination. In order to analysis the integrated archtecture of entire monitoring system,we start this research from each subsystem,and made a detailed explanation for each system's structure, function, construction. This article can provide great help in the construction and research of the large public building energy consumption monitoring system in the future.(3)This article did some research in the large public buildings'energy consumption split modle and the split algorithm. Energy consumption split modle is aimed the electricity consumption in the energy consumption motoring modle. In order to fide which part of building systems'energy consumption is too high and provide a a solid foundation for energy-saving reconstruction. Split algorithm is a key part of the energy consumption spliting. It is crucial for the accuracy level of data.So, only to improve the accuracy of the split algorithm, can provide the accurate, reliable energy data.
