摘　　要：文章以佳木斯市典型草砖民居作为研究对象,进行了为期7d的现场热环境测试,分析当前草砖民居存在的窗户散热严重、室内颗粒物和CO2浓度超标等问题。借助模拟软件Design Builder,确定最佳的窗墙比以及日光间尺寸,以此改善自然通风,降低室内污染物浓度,并可减少耗煤量近10%,为严寒地区农村新建草砖民居及现有民居改造提供了具有实际意义的节能建议。This paper takes typical grass-brick folk houses in Jiamusi City as the research object for conducting a 7-day field thermal environment test to analyze the problems of serious window heat dissipation,indoor particulate matter and CO2 concentration exceeding standard.With help of the simulation software DesignBuilder,we determined the optimal window-to-wall ratio and sunlight room size for improving natural ventilation,reducing indoor pollutant concentration,and nearly 10%of coal consumption can be reduced hereto.And practical energy saving suggestion is thereof provided for building new grass-brick folk houses and remolding existing grass-brick folk houses in severe cold rural regions.
