【摘要】：居住建筑节能研究一直是我国建筑节能研究工作中的一个重要工作。北方寒冷和严寒地区的居住建筑只需考虑冬季保温，围护结构也只需增加保温材料的厚度，，夏热冬暖地区也只要考虑夏季隔热，不需要进行围护结构保温处理。然而，夏热冬冷地区要兼顾夏季隔热和冬季保温，因此夏热冬冷地区的节能设计是研究的难点。当前，长沙地区节能住宅冬夏季室内热环境改善和能耗降低的效果不明显，一方面影响业主以及开发商的积极性，同时又需增加投入，提高造价造成了新的浪费。因此，提出适用于湖南长沙地区的整体节能设计策略，是目前亟待解决的问题。对于夏热冬冷地区建筑节能方面的研究，国内已经进行了诸多方面的探讨，但进行整体设计策略性的研究较少，相关的系统性论著更是少见。笔者通过参与课题，并基于现有研究成果和对节能策略的进一步研究，利用软件模拟和实地测试相结合的方法，研究出该地区住宅节能的最佳设计策略。首先通过资料统计和分析，总结长沙地区传统与现代住宅平面及构造优势，并分析归纳当地的气候类型及特点，从建筑空间和平面设计、围护结构设计、被动式策略及行为模式等方面，总结出典型住宅户型。然后，在保持热环境舒适的情况下，以能耗为评价指标，通过Designbuild软件建立典型户型，有序的进行软件模拟实验：通过围护结构能耗比例模拟，确定围护结构能耗影响因素中的重点对象，针对这些影响因素，以间歇型和连续型两种能耗方式，分别进行模拟，得到围护结构及被动策略的相关设计策略。再通过实地测试改造前后传统住宅的能耗改善效果，来验证设计策略的可行性。最后总结出长沙地区以能耗为目标的住宅节能设计策略。
[Abstract]:Residential building energy conservation research has been an important work in the research of building energy conservation in China. The residential buildings in the cold and cold areas of the north only need to consider the winter insulation, and the enclosure structure only needs to increase the thickness of the insulation materials. In the hot summer and warm winter areas, only the heat insulation in summer is considered, and there is no need for the thermal insulation of the enclosure structure. However, heat insulation in summer and heat preservation in winter should be taken into account in hot summer and cold winter area, so energy saving design in hot summer and cold winter area is a difficult point. At present, the improvement of indoor thermal environment and the reduction of energy consumption of energy-saving residential buildings in Changsha are not obvious. On the one hand, it affects the enthusiasm of the owners and developers, and at the same time, it needs to increase investment, which results in a new waste. Therefore, it is an urgent problem to put forward the overall energy-saving design strategy for Hunan Changsha area. For the study of building energy efficiency in hot summer and cold winter area, many aspects have been discussed in China, but the overall design strategy research is less, and the related systematic works are more rare. Based on the existing research results and the further research on energy-saving strategy, the author studies the best design strategy of residential energy saving in this area by using the method of software simulation and field test. Firstly, through statistics and analysis of data, this paper summarizes the advantages of traditional and modern residential flat and structure in Changsha area, and analyzes and summarizes the local climate types and characteristics, including architectural space and plane design, enclosure structure design. Passive strategies and behavior patterns, summed up the typical residential units. Then, under the condition of keeping the thermal environment comfortable, taking the energy consumption as the evaluation index, the typical household type is established by the Designbuild software, and the software simulation experiment is carried out in an orderly manner: through the simulation of the proportion of energy consumption of the envelope structure, The key objects of the factors affecting the energy consumption of the enclosure structure are determined. According to these factors, the intermittent and continuous energy consumption modes are simulated respectively, and the related design strategies of the envelope structure and passive strategy are obtained. The feasibility of the design strategy is verified by field test of the energy consumption improvement effect of the traditional residence before and after the retrofit. Finally, the energy-saving design strategy for residential buildings in Changsha is summarized.
