【摘要】：既有建筑的节能改造是建筑节能的重要内容。随着我国经济和社会的发展，农村住宅的节能改造业已进入了蓬勃发展的新时期。但目前国内外的住宅节能研究较多集中在城市地区，而对我国广大农村地区住宅的节能改造研究，在很多层面上严重滞后，例如目前针对农村住宅平屋顶改造后的节能效果方面，，没有相关的评价和预测研究，导致该区域很多农村住宅的节能改造还停留在自发性阶段，节能的方法虽然五花八门，但无法保证节能改造的预期效果。因此本研究以典型的夏热冬冷地区——长沙市为例，针对长沙市农村住宅实际情况，结合已有建筑节能评价研究成果，探索适用于农村住宅平屋顶的节能改造评估方法。本研究可弥补国内在该领域研究上的不足，对农村住宅实现两型社会的目标具有较大的紧迫性和现实意义。本论文拟针对长沙地区农村住宅平屋顶开展节能改造评价体系的建构与应用研究，具体包括4个方面内容： 1.评价指标体系的建构本研究结合长沙当地农村住宅调研的实际情况（气候条件、生产特点、施工水平、经济状况等），建立了包括改造后节能效果、原屋顶生产功能的保留程度、施工工艺的影响和技术经济等在内的4个基准层、6个指标层的长沙地区农村住宅平屋顶节能改造综合评估方法。 2.评价指标权重的分析在对各指标进行权重分析时，选取与节能改造相关的4类人群进行专家问卷调查，并采用AHP法进行权重的计算，力求各因子的权重能够充分反映客观事实。 3.农村住宅平屋顶节能改造效益分析模型的建立文章综合节能改造系统工程理论、模糊数学理论和灰色系统理论等确定综合评价方法，以构建农村住宅平屋顶节能改造的效益分析模型作为最终的评价工具。 4.实例应用在前文研究的基础上，文章最后还引入选取的农村住宅原型和平屋顶节能改造方案，并结合农村实地的调研数据及专家评分，对前文建立的农村住宅平屋顶节能改造评价体系进行实例应用，得出最终评价结果，以初步验证该综合评估方法的合理性、科学性和实用性。本评估方法是针对长沙地区农村住宅平屋顶实际情况而建立的，希望通过对各改造方案的综合评价和比选，用户能做出更加合理的选择；同时，也希望能进一步规范和制约农村住宅平屋顶节能改造市场，最终为人民居住环境的建设和建筑节能事业的发展服务。
[Abstract]:With the development of economy and society in our country, the energy-saving transformation of rural housing has entered a new period of vigorous development. However, at present, most of the research on residential energy conservation at home and abroad is concentrated in urban areas, and the research on the energy-saving transformation of residential buildings in the vast rural areas of our country is seriously lagging behind in many aspects. For example, at present, there is no relevant evaluation and prediction study on the energy-saving effect of the flat roof renovation of rural housing, which leads to the fact that many rural residential buildings in this region are still in the spontaneous stage. Although there are various ways to save energy, But it can not guarantee the expected effect of energy saving reconstruction. Therefore, this study takes Changsha City, a typical hot summer and cold winter area, as an example, according to the actual situation of rural residential buildings in Changsha City, combined with the existing research results of building energy conservation evaluation. This study can make up for the deficiency of domestic research in this field and has great urgency and practical significance for rural housing to realize the goal of two-type society. This paper aims at the construction and application of energy saving evaluation system of rural residential flat roof in Changsha area, including four aspects:. 1. Construction of evaluation index system. This study combined with the actual situation of Changsha local rural residential research (climate conditions, production characteristics, construction level, economic situation, etc.), established including the retrofit energy-saving effect, the original roof production function retention, The comprehensive evaluation method for energy saving reconstruction of rural residential flat roof in Changsha area, including the influence of construction technology and technical economy, including four reference layers and six index layers. 2. Analysis of the weights of evaluation indicators. In the weight analysis of each index, four groups of people related to energy saving reform are selected to carry out expert questionnaire survey, and AHP method is used to calculate the weight, so that the weight of each factor can fully reflect the objective facts. 3.Establishment of benefit analysis model for energy saving renovation of flat roof of rural residence. In this paper, the system engineering theory, fuzzy mathematics theory and grey system theory of energy saving reconstruction are integrated to determine the comprehensive evaluation method, and the benefit analysis model of energy saving reconstruction of flat roof of rural residence is constructed as the final evaluation tool. 4. Example applications. On the basis of the previous research, the paper also introduces the selected rural housing prototype and roof energy-saving reconstruction scheme, and combines with the rural field research data and expert score. The evaluation system for energy saving of flat roof of rural residential building was established in this paper, and the final evaluation result was obtained to verify the rationality, scientific and practicability of the comprehensive evaluation method. The evaluation method is based on the actual situation of the flat roof of the rural housing in Changsha area. It is hoped that the users can make more reasonable choices through the comprehensive evaluation and comparison of the reconstruction schemes; at the same time, It also hopes to further standardize and restrict the market of energy saving transformation of rural residential flat roof, and finally serve for the construction of people's living environment and the development of building energy conservation cause.
