Construction And Application Of Campus Building Energy Evaluation Model Based On Dynamic Weight

With the constant expansion of universities, the area of the campus, the number ofstudents, faculty and staff increased dramatically in recent years. In particular, the growth inenergy consumption costs was several times over the past. The energy consumption costs toomuch. The campus buildings have become an important energy guzzler. According to thesurvey, the energy consumption of campus buildings in China accounted for8%of the totalsocial energy consumption. Energy consumption per capita of campus is higher than that ofthe community. The energy efficiency of campus buildings, as an important part of the energyefficiency of public buildings, is paid more and more attention by people. To promote theenergy efficiency of Campus building, will help reduce the energy consumption expendituresof campus buildings. But how to proceed the energy conservation, lots of energy-savingmanagers feel overwhelmed. The reason is that the building energy saving managementunable to know the status of energy-saving degree, it is unclear what factors affect thebuilding energy efficiency, but also do not know what kind of energy-saving measures shouldbe taken. In response to this phenomenon, this paper presents an energy-saving evaluationmodel based on dynamic weighting, by combining a large number of actual energyconsumption data for support, to implement energy-saving evaluation of real-time and quickfeedback. It will help managers make clear energy-saving direction to take measures. Also itwill truly reduce building energy consumption to achieve effective energy-saving purposes.In this paper, the key research work and achievements have the following severalaspects:First of all, the paper introduces the development and research status of building energyefficiency evaluation system; Describing the significance of building energy efficiencyevaluation and analyzing the emphasis and difficulty in building energy efficiency evaluation,and then putting forward the existing problems.Secondly, the paper describes the general idea and steps of constructing evaluation model.Each step is described in detail, including the selection process of indexes, the frameworkdesign of evaluation model, the distribution of weight among indexes and the calculation andclassification of evaluation results, etc.Third, this paper focuses on the distribution of weight. It points out the defects of theexisting fixed weight distribution, and combined with the connotation of the selected indexand the effect between indexes, then proposed the optimizing dynamic weight allocationmethod. Dynamic weight allocation method is on the basis of the static weight, according to the range that multiple indexes may fall and impact on overall evaluation results, putting theinformation iteration to the model in the calculation of weight of index. Due to the value ofeach index was got during application, so the weight of index is real-time calculated in theprocess of application. In the end, the evaluation model of dynamic weight real-timedistribution was build.Finally, it chooses some campus buildings as pilots with acquiring a large number of dataand parameter values, providing sample data for evaluation model, and energy conservationassessment by a dynamic weight distribution of evaluation model. Since of large number ofindexes, large amount of data acquisition, and calculating dynamic weight repeatedly andreal-time, the computer program of the model is adopted for automatic weight calculation andthe result analysis. To two tests: different weights allocation method, similarly hereinaftersamples; dynamic weights allocation of different samples. The test results show that thedynamic weight distribution is better than that of static weight; The energy efficiencyevaluation results of campus buildings based on dynamic weight distribution are reasonableand effective.
