【摘要】：当前,随着资源能源的日益短缺及环境的日益恶化,城市化进程中的“大拆大建”模式逐渐被新的建设模式-改造再利用所取代。工业厂房建造的主要目的是用于工业生产,绝大部分为非节能建筑物,功能转型存在能耗高、节能潜力大、舒适度不足等问题。在这个注重绿色、节能、环保的大环境下,节能改造是解决旧工业厂房节能性、舒适性和环境性偏低等症结的有效途径。然而,节能改造项目初期投资大,回收期长,明确其效益状况有利于改造工作的大规模开展,因此,科学评价旧工业厂房节能改造项目的效益并指导今后项目的决策和实施,已成为亟需解决的问题。本文主要对北方采暖地区旧工业厂房功能置换为办公建筑的效益进行评价,具体有以下几方面内容:(1)在参与旧工业厂房节能改造项目实践和查阅相关文献资料的基础上,分析旧工业厂房节能改造的背景,总结节能改造与普通改造的本质区别,并对节能改造效益评价研究中存在的问题进行分析,确定文章的研究内容和技术路线。(2)分析北方采暖地区旧工业厂房能耗构成和6个影响能耗的因素,从围护结构、室内采暖系统、热源热网三方面介绍旧工业厂房节能改造的技术内容,并对旧工业厂房节能改造效益研究依托的可拓理论和数据包络分析理论进行概述。(3)将旧工业厂房节能改造的效益从功能、经济、社会和环境四方面进行划分,再进行效益细化分析,并推导各项效益的计算公式,将效益量化。(4)遵循科学、全面、系统、层次、独立原则,建立有代表性的评价指标体系,并对指标体系全部进行量化和无量纲处理,提高了评价的客观性。为了克服主观赋权法的弊端,本文采用可拓学中的可拓权重法来确定各指标的权重。运用可拓评价法评价单个改造项目的效益等级;然后运用数据包络分析法建立C~2R模型评价多个相似改造项目的相对有效性,为改造项目提供有效的管理信息和经济信息。(5)结合旧工业厂房节能改造项目实例,验证模型的可行性,分析评价结果,提出改善节能改造项目效益的途径,为今后旧工业厂房节能改造决策和实施提供参考。
[Abstract]:At present, with the increasingly shortage of resources and energy and the worsening of the environment, the "big demolition and construction" model in the process of urbanization is gradually replaced by the new construction mode-reconstruction and reuse. The main purpose of industrial factory building is to use it in industrial production, most of which are non-energy saving buildings. The function transformation has many problems, such as high energy consumption, great energy saving potential, insufficient comfort and so on. In this environment of focusing on green, energy saving and environmental protection, energy saving reform is an effective way to solve the problem of energy saving, comfort and low environment of old industrial buildings. However, the initial investment of the energy-saving renovation project is large, the payback period is long, and it is advantageous to carry out the reconstruction work on a large scale by making clear its benefit condition. Therefore, it is necessary to scientifically evaluate the benefit of the energy-saving renovation project of the old industrial factory building and to guide the decision and implementation of the future project. It has become an urgent problem to solve. This paper mainly evaluates the benefit of replacing the function of the old industrial factory building with office building in the north heating area. The specific contents are as follows: 1) on the basis of participating in the practice of the energy saving renovation project of the old industrial factory building and consulting the relevant documents, This paper analyzes the background of the energy-saving transformation of the old industrial buildings, summarizes the essential differences between the energy-saving transformation and the ordinary transformation, and analyzes the problems existing in the research on the evaluation of the benefits of the energy-saving transformation. Determine the research content and technical route of the article. (2) analyze the energy consumption composition of the old industrial building in the northern heating area and six factors affecting energy consumption, from the envelope structure, indoor heating system, This paper introduces the technical contents of energy saving transformation of old industrial factory building from three aspects of heat source and heat network, and summarizes the extension theory and data envelopment analysis theory, which is based on the research on the efficiency of energy saving transformation of old industrial building. The four aspects of economy, society and environment are divided, then the benefit is analyzed in detail, and the calculation formula of each benefit is deduced, and the benefit is quantified according to the principles of science, comprehensiveness, system, hierarchy and independence. The objectivity of evaluation is improved by establishing representative evaluation index system, quantifying and dimensionless the index system. In order to overcome the disadvantages of subjective weighting method, the extension weight method is used to determine the weights of each index. The extension evaluation method is used to evaluate the benefit grade of a single transformation project, and then the Cn2R model is established to evaluate the relative effectiveness of several similar reconstruction projects by using the data envelopment analysis method. To provide effective management information and economic information for the retrofit project, combined with the example of energy-saving transformation project of old industrial factory building, to verify the feasibility of the model, to analyze the evaluation results, and to put forward the ways to improve the efficiency of the energy-saving renovation project. It provides a reference for the decision and implementation of energy saving transformation of old industrial buildings in the future.
