摘　　要：为改善传统改性生土室内热工环境,借助Designbuilder软件,对某改性生土民居在3种不同的保温构造情况下,分别在夏时令和冬时令的自然环境中,进行建筑室内环境热工和相对湿度的模拟分析。通过分析发现,生土材料本身具备良好的温度和湿度调节能力。使用聚苯乙烯泡沫材料和硬泡聚氨酯保温结构层,对室内温度的调控效果更好。而以农村常见的秸秆作为保温构造的生土墙体,可以将室内相对湿度较长时间地处于人体相对舒适的环境。In order to improve the indoor thermal environment of traditional modified earth buildings,the thermal engineering and relative humidity of the indoor environment of the building were simulated and analyzed in the natural environment of summer and winter respectively under the condition of three different thermal insulation structures using the Designbuilder software.Through the analysis,it is found that the raw soil material itself has good temperature and humidity regulating ability.The use of polystyrene foam material and rigid foam polyurethane insulation structure layer,the effect of indoor temperature control is better.The raw soil wall with common agricultural waste as the insulation structure can keep the indoor relative humidity in a relatively comfortable environment for a long time.

关 键 词：室内热工环境 保温构造 热工性能模拟分析 改性生土建筑
