摘　　要：低碳环保的木结构建筑是桂北农村地区极具代表性的建筑。为充分了解传统木构民居夏季室内热环境现状,选取龙胜泗水乡的1个典型民居作为研究对象,测试其夏季热环境参数。结果表明:桂北山区传统木构民居建筑因木材特性,墙体热阻大、隔热性能好,夏季卧室内的温度较低;但坐东朝西、西向大窗墙比的构造方式使得堂屋内的温度较高,且围护结构热惯性小,衰减系数大,延迟时间短,室内热稳定性较差,宜对民居西向窗墙比大小、遮阳形式和外墙围护结构热工性能进行优化设计。Low-carbon and environmentally friendly wooden buildings are highly representative building types in the rural areas of northern Guangxi.In order to fully understand the current situation of the summer indoor thermal environment of traditional wooden dwellings,a typical dwelling in Sishui Township,Longsheng,was selected as the research object to test its summer thermal environment parameters.The results showed that the bedroom temperature of the traditional wooden dwellings in the mountainous area of northern Guangxi was low in summer because of the characteristics of wood,the large thermal resistance of walls and good thermal insulation performance.However,the structure of the building facing west and the large window-wall ratio make the temperature in the central room high,and the thermal inertia of the envelope is small,the decrement factor is large,the time lag is short,and the indoor thermal stability is poor.Therefore,it is necessary to optimize the size of the west window-to-wall ratio,the form of shading,and the thermal performance of the exterior wall envelope.
