【摘要】：近些年,随着我国城镇化进程的不断加快,传统建筑,尤其是传统民居正在以惊人的速度消失,随之而去的还有传统民居中因地制宜的气候适应性技术。在能源紧缺、环境污染等问题日益突出的今天,这些气候适应性技术不仅是传统文化传承的载体,同时也为现代建筑的节能技术提供了参考。本文以徽州民居作为研究对象,首先通过实地调研、室内热环境现场测试等方法,分析和探讨了传统民居中所蕴含的被动式节能技术。并对这些被动式节能技术的参数进行了理论计算,同时结合现代建筑材料和工艺对其进行优化和改良,作为徽州民居的被动节能技术改造方案。以太阳能光伏发电和地源热泵空调系统作为徽州民居主动节能技术改造方案。其次,对徽州民居生命周期阶段成本进行了划分,建立了徽州民居材料生产、运输、施工、运行、维护管理、中修年替换以及拆除回收七个阶段的生命周期成本模型,并通过年度和非年度成本模型对其进行折现。计算被动式节能技术的生命周期成本净现值,从而对比找出最优化的被动节能技术改造方案。构建了新能源利用技术的生命周期增量成本和增量效益模型,分析新能源利用技术给徽州民居所带来的效益。同时引入增量投资动态回收期和内部收益率两个指标分析徽州民居节能改造方案的经济可行性。最后,本文选取了徽州地区典型的现代民居进行案例分析,运用生命周期成本的理论对节能技术方案进行评估,结果表明:在单个围护结构改建方案中,依据坡屋顶改建方案的生命周期成本最低。在组合围护结构改建方案中,生命周期成本最低的是空斗砖墙+坡屋顶+地笼结构改建的方案。但是坡屋顶+地笼结构改建方案的增量投资动态回收期最短、内部收益率最大,应用前景更好。太阳能光伏发电和地源热泵空调系统均可节约一定的生命周期成本,同时其增量投资动态回收期和内部收益率都得到了改善。电价对各节能优化方案评估结果的敏感性分析结果表明:电价的上升更加有利于地源热泵空调系统在该地区的推广使用。
[Abstract]:In recent years, with the rapid development of urbanization in our country, traditional buildings, especially traditional houses, are disappearing at an amazing speed, and then there is the climate adaptation technology in traditional houses. Nowadays, energy shortage and environmental pollution are becoming more and more prominent. These climate adaptive technologies are not only the carrier of traditional culture inheritance, but also provide reference for energy saving technology of modern buildings. In this paper, Huizhou residence as the research object, first through the field investigation, indoor thermal environment field testing and other methods, analysis and discussion of the traditional residential houses contained in passive energy saving technology. The parameters of these passive energy-saving technologies are calculated theoretically and optimized and improved by combining modern building materials and techniques as the passive energy-saving technical renovation scheme of Huizhou residential buildings. Solar photovoltaic power generation and ground-source heat pump air conditioning system as Huizhou residential active energy-saving technology transformation scheme. Secondly, the life-cycle cost of Huizhou dwelling is divided into seven stages: material production, transportation, construction, operation, maintenance and management, annual replacement and removal and recovery. It is discounted by annual and non-annual cost models. The net present value of the life cycle cost of passive energy saving technology is calculated, and the optimized passive energy saving technology reform scheme is compared and found out. The life cycle incremental cost and increment benefit model of new energy utilization technology is constructed, and the benefit of new energy utilization technology to Huizhou dwelling is analyzed. At the same time, the dynamic recovery period of incremental investment and the internal rate of return are introduced to analyze the economic feasibility of Huizhou residential energy-saving reconstruction scheme. Finally, this paper selects the typical modern residential buildings in Huizhou area to carry on the case analysis, uses the life cycle cost theory to carry on the appraisal to the energy saving technical plan, the result shows that: in the single enclosure structure reconstruction plan, According to the slope roof reconstruction scheme, the life cycle cost is the lowest. In the reconstruction scheme of composite enclosure structure, the lowest life-cycle cost is the reconstruction scheme of empty bucket brick wall sloping roof and floor cage structure. But the dynamic recovery period of incremental investment is the shortest, the internal rate of return is the largest, and the application prospect is better. Solar photovoltaic power generation and ground-source heat pump air conditioning system can save a certain life cycle cost, and its incremental investment dynamic recovery period and internal rate of return are improved. The sensitivity analysis of electricity price to the evaluation results of various energy-saving optimization schemes shows that the rise of electricity price is more conducive to the popularization and use of ground-source heat pump air conditioning system in this area.
