摘　　要：为了解草砖建筑热工性能和室内热环境,选取汤原县一草砖建筑和当地典型砖混民居进行冬季室内外热环境和室内空气质量对比测试,结果表明:相对于砖混建筑,草砖墙体具有保温节煤、调节室内湿度的作用.但草砖墙体内表面温度振幅较大,在夜间墙体壁面温度低于室内空气温度,易形成冷辐射.To test thermal performance,indoor thermal environment and indoor air quality of straw bale buildings in northeast of China,a straw bale building built in 2002 and local typical brick dwellings built in 2008 were selected.Results showed that compared with brick wall of the same thickness,the straw bale walls functioned as adjuster of indoor air humidity and thermal insulation.The amplitude of inner surface temperature of straw bale walls were larger than that of brick walls,which was lower than it was at night,forming cold radiation to residents.
