【摘要】：中国的建筑能耗占社会终端能耗比重高,是节能减排的重要领域,因此进行建筑节能势在必行。我国采暖区居住建筑的围护结构保温蓄热能力差,通过围护结构散失的热量占系统热量损失的70%,应重点研究居住建筑围护结构节能改造领域。居住建筑围护结构节能改造的有效实施涉及到的因素众多,其中起关键性作用的因素就是围护结构节能改造方案的优选,围护结构节能改造方案的合理程度对降低节能改造的实施成本和保证节能改造后的使用效益、经济效益和环境效益至关重要。论文通过对我国采暖区气候地理特征进行分析的基础上将“适宜性技术”理念引入我国采暖区居住建筑围护结构的节能改造;通过分析我国采暖区居住建筑围护结构节能设计标准,从“适宜性技术”理念、节能和使用功能的角度出发构建居住建筑围护结构节能改造方案的功能评价指标体系,确定指标标度,运用三角模糊数属性层次模型确定指标的权重,计算方案的功能系数,运用全寿命周期理论构建居住建筑围护结构节能改造方案的全寿命周期成本年值的计算方法,计算方案的成本系数,从而构建我国采暖区居住建筑围护结构节能改造方案的优选模型;通过实证分析,运用优选模型选取北京市中关村南大街某民用居住建筑围护结构节能改造三种设计方案中价值最大的改造方案来验证优选模型的适用性。我国采暖区居住建筑围护结构节能改造方案优选的研究可以为节能改造实施方选择最有价值的节能改造方案,提高改造效果,节约改造成本提供理论借鉴。
[Abstract]:Building energy consumption in China occupies a high proportion of social terminal energy consumption, which is an important field of energy saving and emission reduction. Therefore, building energy saving is imperative. Through the heat loss of the enclosure structure accounts for 70% of the system heat loss, we should focus on the residential building envelope energy saving transformation field. The effective implementation of the residential building envelope structure energy saving reform involves many factors. Among them, the key factor is the optimal selection of the energy-saving transformation scheme of the envelope structure. The reasonable degree of the energy-saving transformation scheme of the envelope structure can reduce the implementation cost of the energy-saving transformation and ensure the use benefit after the energy-saving transformation. The economic benefit and environmental benefit are very important. Based on the analysis of the climatic and geographical characteristics of heating area in China, the idea of "suitability technology" is introduced into the energy-saving transformation of the enclosure structure of residential building in the heating area of our country. Based on the analysis of energy saving design standard of residential building envelope structure in heating area of our country, the concept of "suitability technology" is discussed in this paper. From the point of view of energy saving and using function, this paper constructs the function evaluation index system of the energy-saving reconstruction scheme of residential building envelope structure, determines the index scale, and uses the triangular fuzzy number attribute hierarchy model to determine the weight of the index. The function coefficient of the scheme is calculated, and the method of calculating the annual value of the whole life cycle cost and the cost coefficient of the scheme are constructed by using the theory of the whole life cycle. In order to construct the optimal model of energy-saving reconstruction scheme of residential building envelope in heating area of our country; Through empirical analysis. In order to verify the applicability of the optimal selection model, the optimal selection model is used to select the three most valuable retrofit schemes of the envelope structure of a civil residential building in Nanjie, Zhongguancun, Beijing, and to verify the applicability of the optimal selection model. The research on the optimal selection of energy-saving reconstruction scheme of protective structure can select the most valuable energy-saving retrofit scheme for the implementation of energy-saving transformation. Improve the effect of transformation, save the cost of reconstruction to provide theoretical reference.
