【摘要】：我国实行改革开放以来,经济实力得到了飞速增长,人们对于建筑功能的要求随着时代的变迁而发生改变,由以前功能比较单一的住房需求进而转向功能多元化的住宅需求模式。目前我国建筑行业耗能总量约占社会总能耗的三分之一以上,其中住宅耗能所占比重逐步加大,尤其以住宅围护结构方面的能耗损失更为严重,非常不利于经济可持续发展。所以,住宅围护结构方面节能研究工作已经成为世界各国关注的焦点,同时也是各国关注的重要科研课题之一。本文从宏观经济角度对夏热冬冷地区住宅围护结构节能评价进行了研究。首先分析了夏热冬冷地区住宅能耗特点,研究了主要围护结构节能技术；然后进行了基于DeST的住宅能耗模拟计算,定义了住宅围护结构参数,建立了各围护结构热传递引起的冷负荷计算公式及住宅能耗量推理计算公式,选取了节能评价模型指标；最后,以具体工程项目为例进行了节能措施前后住宅模型能耗的动态模拟计算,进而进行了节能前后能耗量的对比分析,并完成了基于动态-增量分析法的节能评价,验证了对围护结构进行节能投资的经济可行性。通过节能评价研究,本文提出住宅节能设计应从源头开始,结合夏热冬冷地区的气候环境条件,充分利用一切手段使节能技术和措施在住宅设计时有机融入其中,进一步推动我国节能建筑的发展。针对我国夏热冬冷地区的气候环境条件,运用建筑能耗计算软件DeST对项目进行实体模拟能够得到比较准确的数据,基于动态-增量分析的节能评价方法在夏热冬冷地区住宅围护结构节能评价中具有较高的实际应用价值。
[Abstract]:Since the implementation of reform and opening up in China, the economic strength has been growing rapidly, and people's requirements for building functions have changed with the change of the times. From the former function of a single housing demand and then to a diversified housing demand model. At present, the total energy consumption of the construction industry in China accounts for more than 1/3 of the total social energy consumption, among which the proportion of residential energy consumption is gradually increasing, especially the energy loss of housing envelope structure is more serious, which is very harmful to the sustainable development of economy. Therefore, the research work of energy saving in housing envelope structure has become the focus of attention in the world, and it is also one of the important scientific research topics concerned by all countries. In this paper, the energy-saving evaluation of residential enclosure structure in hot summer and cold winter area is studied from the macro-economic point of view. Firstly, the characteristics of residential energy consumption in hot summer and cold winter area are analyzed, and the energy saving technology of main enclosure structure is studied. Then, the simulation calculation of residential energy consumption based on DeST is carried out, the parameters of housing enclosure structure are defined, the calculation formula of cooling load caused by heat transfer of each enclosure structure and the reasoning calculation formula of residential energy consumption are established, and the index of energy saving evaluation model is selected. Finally, taking the specific project as an example, the dynamic simulation calculation of energy consumption of residential model before and after energy-saving measures is carried out, and then the comparative analysis of energy consumption before and after energy saving is carried out, and the energy saving evaluation based on dynamic and incremental analysis method is completed. The economic feasibility of energy saving investment in enclosure structure is verified. Through the research of energy conservation evaluation, this paper puts forward that the energy saving design of housing should be started from the source, combined with the climatic and environmental conditions in the hot summer and cold winter area, and make full use of all means to make the energy saving technology and measures integrate into the residential design organically. Further promote the development of energy-efficient buildings in China. In view of the climatic and environmental conditions in hot summer and cold winter area in China, using the building energy consumption calculation software DeST to simulate the project can get more accurate data. The energy conservation evaluation method based on dynamic and incremental analysis has high practical application value in the energy saving evaluation of residential enclosure structure in hot summer and cold winter area.
