【摘要】：近幾年來隨著高校規(guī)模的不斷擴(kuò)大，校園面積、學(xué)生人數(shù)、教職員工人數(shù)急劇增多，各高校在公共費用支出方面都比過去有了大幅度的提高。特別是校園建筑能源消耗費用呈數(shù)倍增長，使用能源費用支出過大，儼然成為重要的能源消耗大戶。據(jù)調(diào)查顯示，我國高校建筑能源消耗占社會總能耗的8%，在校生的人均能耗高于社會人均能耗。校園建筑節(jié)能，作為公共建筑節(jié)能的重要組成部分，受到人們越來越多的關(guān)注。推進(jìn)校園建筑節(jié)能工作，將有利于降低校園建筑的能耗支出。但是真正開展節(jié)能工作時，很多節(jié)能管理者卻不知道應(yīng)該從何入手。原因在于，節(jié)能管理者對建筑節(jié)能程度現(xiàn)狀無從了解，不清楚哪些因素影響了建筑節(jié)能，也就不知道應(yīng)該采取什么樣的節(jié)能措施。針對這一現(xiàn)象，本文提出了一種基于動態(tài)權(quán)重的校園建筑節(jié)能評價模型，通過結(jié)合大量實際能耗數(shù)據(jù)作支撐，實現(xiàn)實時、快速地反饋建筑實際運行的節(jié)能評價，幫助節(jié)能管理者明確節(jié)能方向和措施，真正實現(xiàn)建筑能源消耗量的降低，達(dá)到有效節(jié)能的目的。 本文主要研究工作及成果有以下幾個方面： 首先，系統(tǒng)介紹了當(dāng)前建筑節(jié)能評價模型的發(fā)展及研究現(xiàn)狀，描述建筑節(jié)能評價的意義，分析了校園建筑節(jié)能評價的重點和難點，并對目前評價模型存在局限提出問題。 其次，根據(jù)目前評價模型固定權(quán)重分配的缺陷，結(jié)合所選取指標(biāo)的內(nèi)涵與指標(biāo)之間相互的影響度，提出了基于動態(tài)權(quán)重的建筑節(jié)能評價模型。動態(tài)權(quán)重評價模型是指在靜態(tài)權(quán)重的基礎(chǔ)上，根據(jù)模型中多個指標(biāo)可能落到的區(qū)間和對總體評價結(jié)果的影響程度，將這些信息迭代到模型中各指標(biāo)的權(quán)重計算中。由于各指標(biāo)的取值是在應(yīng)用中才能獲取，故指標(biāo)的權(quán)重也是在應(yīng)用過程中才實時計算出來，從而構(gòu)建了實時動態(tài)權(quán)重分配的評價模型。 然后，設(shè)計動態(tài)權(quán)重評價模型在校園建筑中的應(yīng)用平臺。先進(jìn)行指標(biāo)的選取過程、評價模型的框架設(shè)計、指標(biāo)模型的權(quán)重分配以及評價結(jié)果計算和分級等。通過大量數(shù)據(jù)采集，獲取指標(biāo)值，為評價模型提供樣本數(shù)據(jù)，采用動態(tài)權(quán)重評價模型對該棟建筑作出節(jié)能評價。由于評價模型涉及指標(biāo)數(shù)量多、數(shù)據(jù)采集量大，且需要進(jìn)行實時反復(fù)的動態(tài)權(quán)重計算，故采用計算程序?qū)δＰ瓦M(jìn)行自動化權(quán)重計算和結(jié)果對比分析。 最后，對動態(tài)權(quán)重評價模型進(jìn)行了實例測試：通過靜態(tài)權(quán)重均分評價模型和動態(tài)權(quán)重評價模型對校園建筑連續(xù)20天進(jìn)行不間斷持續(xù)性評價。根據(jù)兩種評價原理的不同，求同去異，用統(tǒng)一的衡量方式量化出動態(tài)權(quán)重評價模型相比于靜態(tài)權(quán)重均分評價模型的優(yōu)化程度。測試結(jié)果表明：動態(tài)權(quán)重評價模型明顯優(yōu)于靜態(tài)權(quán)重均分評價模型，，基于動態(tài)權(quán)重的校園建筑節(jié)能評價模型使得評價結(jié)果更有區(qū)分度。
[Abstract]:In recent years, with the continuous expansion of the scale of colleges and universities, the area of campus, the number of students, the number of teaching staff has increased sharply, and the public expenditure of colleges and universities has been greatly increased compared with the past. In particular, the energy consumption of campus buildings has increased several times, and the cost of using energy is too large, so it has become an important energy consumer. According to the investigation, the energy consumption of college buildings accounts for 8% of the total energy consumption, and the average energy consumption of college students is higher than that of the society. Campus building energy-saving, as an important part of public building energy-saving, has received more and more attention. Promoting the work of energy saving in campus buildings will help to reduce the energy expenditure of campus buildings. But when it comes to energy-saving, many managers don't know where to start. The reason is that the managers of energy conservation have no idea of the current situation of building energy saving, and do not know which factors affect the building energy saving, so they do not know what energy saving measures should be taken. In view of this phenomenon, this paper puts forward a kind of campus building energy saving evaluation model based on dynamic weight. By combining a large amount of actual energy consumption data as the support, the paper realizes real-time and fast feedback on the energy saving evaluation of the actual operation of the building. To help energy conservation managers to clear the direction and measures of energy conservation, to achieve the real energy consumption of buildings to reduce energy consumption, to achieve the purpose of effective energy conservation. The main research work and achievements in this paper are as follows: firstly, the development and research status of building energy conservation evaluation model are systematically introduced, and the significance of building energy efficiency evaluation is described. This paper analyzes on the key points and difficulties in the evaluation of campus building energy conservation, and puts forward some questions about the limitations of the current evaluation model. Secondly, according to the defects of fixed weight distribution in the current evaluation model, combined with the connotation of the selected index and the degree of mutual influence between the indicators, a dynamic weight based building energy conservation evaluation model is proposed. On the basis of static weight, dynamic weight evaluation model iterates these information into the weight calculation of each index in the model according to the interval that several indexes in the model may fall and the degree of influence on the overall evaluation result. Because the value of each index can be obtained only in the application, so the weight of the index is calculated in the process of application, thus the evaluation model of real-time dynamic weight allocation is constructed. Then, the application platform of dynamic weight evaluation model in campus architecture is designed. The selection process of index, the frame design of evaluation model, the weight distribution of index model and the calculation and grading of evaluation result are carried out. Through a large amount of data acquisition, the index value is obtained, and the sample data are provided for the evaluation model. The dynamic weight evaluation model is used to evaluate the energy conservation of the building. Because the evaluation model involves a large number of indexes and a large amount of data acquisition, and needs to carry out real-time repeated dynamic weight calculation, the calculation program is used to calculate the automatic weight of the model and the results are compared and analyzed. Finally, the dynamic weight evaluation model is tested by an example: the continuous evaluation of campus buildings for 20 consecutive days is carried out through the static average weight distribution evaluation model and the dynamic weight evaluation model. According to the difference of the two evaluation principles, the optimization degree of the dynamic weight evaluation model compared with the static weight mean distribution evaluation model is quantified by a unified measurement method. The test results show that the dynamic weight evaluation model is obviously superior to the static average weight distribution evaluation model, and the campus building energy-saving evaluation model based on the dynamic weight makes the evaluation results more discriminative.
