西安市高校公共建筑能耗預(yù)測模型與節(jié)能管理系統(tǒng)研究
[Abstract]:In recent years, the psychological pressure caused by haze weather has been significantly increased, which can restrain the increasing trend of high energy consumption in the construction industry and make rational use of energy, which will help to alleviate the occurrence of this phenomenon. With the number of college students increasing year by year, the proportion of energy consumption of university buildings to the total social energy consumption is increasing. At present, the energy saving consciousness of college students is not strong, and the building energy saving management system is not perfect, which hinders the development of energy saving work in colleges and universities. Therefore, it is very important to study the change trend of energy consumption of various buildings in colleges and universities and to formulate reasonable energy saving control strategies. The work of energy saving in public buildings in colleges and universities involves the collection and analysis of energy consumption data and the study of energy saving strategies. This paper analyzes the statistical index of energy consumption of public buildings in colleges and universities, the characteristics of energy use and the influencing factors, summarizes the characteristics of energy consumption of public buildings in colleges and universities, and establishes the experimental building, administrative building, teaching building, gymnasium and library based on GA-BP algorithm. The suitable energy consumption prediction model for seven kinds of buildings, dormitory and restaurant, verifies the generality of the model, uses SQL Server 2012 software and MCGS software to build the energy conservation management system of university public buildings, and the new energy consumption prediction model of the system. The functions of the water supply control system, the heating control system and the autonomous reservation system of the study room are tested, and the feasibility of the system is verified. The results show that the energy consumption of lighting accounts for a large proportion of the energy consumption, and the energy consumption of air conditioning in summer may exceed the energy consumption of lighting. The peak value of energy consumption of all kinds of public buildings appeared in June. The prediction effect of GA-BP model is better than that of BP model. The prediction result of BP model is unstable, and the prediction error of multi-dimension input variable may be very large. The new function of energy saving management system runs well, which can provide technical means for energy decision and energy saving plan implementation of university managers.
