【摘要】：能源是现代化的基础和动力,能源供应和能源安全事关我国现代化建设全局。当前,我国能源资源约束日益加剧,生态环境问题突出,能源发展面临一系列新问题新挑战。建筑节能作为节能减排战略体系中的重要内容,近年来逐渐成为全社会关注的焦点问题。在降低建筑能耗的方法中,提高围护结构的保温隔热性能是最直接有效的。墙体是建筑围护结构的重要组成部分,在围护结构的能耗中,外墙耗热量所占的比例最大。因此,作为目前发展最为迅速的一种围护结构节能保温技术一外墙外保温技术成为主导的墙体保温形式。本文以外墙外保温技术为主要研究对象,包括外墙外保温体系技术经济分析和生命周期成本分析两个核心内容。通过对不同外墙外保温体系生命周期成本的实际与模拟测算研究,为评价外墙外保温体系的能效、建立适合北方地区外墙外保温技术发展的成本一价值体系提供了参考。本文主要做了以下工作：(1)对外墙外保温领域的国内外应用和研究现状、推广经验和发展趋势进行了总结。分析了外墙外保温体系的经济性优势,介绍了几种常见的外墙外保温系统构造。(2)通过实际调研对某市外墙外保温技术的推广情况和实施现状进行了充分了解,收集了不同外墙外保温体系的墙体结构、保温层造价、保温层厚度等相关影响因素的数据,根据调研数据对实际案例做了技术性能和经济绩效的一般性评估。(3)基于生命周期成本分析的基本原理,从外墙外保温体系的生命周期成本构成出发,建立了外墙外保温体系的生命周期成本分析模型并结合实际案例针对不同的外墙外保温体系进行了寿命期内的节能效益分析和成本分析。
[Abstract]:Energy is the foundation and motive force of modernization. Energy supply and energy security are related to the overall situation of modernization in China. At present, the restriction of energy resources in our country is becoming more and more serious, the ecological and environmental problems are prominent, and the energy development is facing a series of new problems and new challenges. Building energy conservation as an important part of energy-saving and emission reduction strategy system has gradually become the focus of attention of the whole society in recent years. In order to reduce building energy consumption, it is the most direct and effective way to improve the insulation performance of enclosure. Wall is an important part of building envelope structure. Therefore, as one of the most rapid development of envelope structure energy conservation and insulation technology, external wall insulation technology has become the dominant form of wall insulation. In this paper, the external insulation technology of the external wall as the main research object, including the external wall insulation system technology and economic analysis and life cycle cost analysis of two core content. Through the study on the life cycle cost of different exterior wall thermal insulation systems, this paper provides a reference for evaluating the energy efficiency of external wall insulation system and establishing a cost-value system suitable for the development of external wall thermal insulation technology in North China. The main work of this paper is as follows: (1) the application and research status of exterior wall insulation at home and abroad, the popularization experience and the development trend are summarized. This paper analyzes on the economic advantages of external insulation system of external wall, introduces several common structures of external insulation system of external wall. (2) through actual investigation and investigation, the paper makes a full understanding of the popularization and implementation status of external insulation technology of external wall in a certain city. The data of the wall structure, the cost of the insulation layer, the thickness of the insulation layer and other related factors are collected. According to the investigation data, the paper makes a general evaluation of the technical performance and economic performance of the actual cases. (3) based on the basic principle of life cycle cost analysis, starting from the life cycle cost composition of the exterior wall insulation system, The life cycle cost analysis model of exterior wall thermal insulation system is established, and the energy saving benefit and cost analysis during the life cycle of different exterior wall thermal insulation system are analyzed in combination with practical cases.
