以湘西传统民居的典型代表“吞口屋”为研究对象,通过对其进行夏季和冬季典型日室内热环境实测,分析湘西传统民居的室内热环境状况;在此基础上,利用全年动态能耗模拟软件和计算流体力学软件,进行能耗和自然通风分析,结合当地经济因素和原有建筑历史风格,探讨被动式节能改造措施在湘西传统民居中的应用,并基于正交试验设计提出湘西传统民居最优的综合改造方案:窗户材料选用普通中空玻璃(中空12 mm)、窗墙比提高到0.2、外墙改造使用10 mm聚氨酯保温板的“呼吸式”杉木墙体、屋面改造使用50 mm芦苇箔厚度的黏土屋面。 Taking the typical representative of traditional folk houses in western Hunan Province as the study object, this paper analyzes the typical indoor thermal environment in summer and winter, and analyzes the indoor thermal environment in the traditional residential areas in western Hunan. Based on this, Dynamic energy consumption simulation software and computational fluid dynamics software for energy consumption and natural ventilation analysis, combined with local economic factors and the historical style of the original building to explore the application of passive energy-saving measures in the traditional residential areas in western Hunan and proposed based on orthogonal experimental design Western Hunan traditional residential optimal synthesis program: the use of ordinary hollow glass window material (hollow 12 mm), window ratio increased to 0.2, the outer wall of the 10 mm polyurethane insulation board using the “breathing” fir wall, roof Rebuild clay roofing using 50 mm reed foil thickness.
