摘　　要：选择适宜的墙体材料可有效地降低房屋在使用过程中的能耗,以在建的草砖作为墙体填充材料的房屋为研究对象,通过对建筑室内外温湿度、墙体表面温度的测试分析及其全年采暖能耗模拟分析,对比在其他同等条件下使用普通黏土砖和草砖的能耗情况,结果表明,草砖具有良好的隔热性能,并有一定的湿度调节作用,且其保温特性优异,在大同地区较之于黏土砖节能61.69%。此外,还对比了不同地区草砖房较之于普通黏土砖建筑的能耗状况,结果显示,哈尔滨、大同、西安地区草砖房的节能率分别为56.59%、61.96%、65.55%。据此提出草砖墙体材料应用于严寒、寒冷地区的农村住宅,其节能效果明显,具有普遍的适应性。Choosing the appropriate wall material can reduce the energy consumption effectively , this paper selects a constructing house as the research object which uses straw-bale as the filling material for external wall .Through testing indoor and outdoor temperature and relative humidity and the wall surface temperature ,and simulating annual heating energy consumption , then it is contrasted the energy consumption of using straw-bale and clay brick .The result shows that the straw-bale has good thermal insulation and heat preservation , and it could adjust the indoor relative humidity to some extent , the house using the straw-bale can reduce 61.69% energy consumption comparing with the clay brick houses in Datong , Shanxi Province .The paper also compares the energy conservation of straw-bale house and clay brick house in different climate zone , and the result indicates that as compared with the clay brick house,the straw-bale house can reduce 56.59%, 61.96%and 65.55% energy consumption in Harbin , Xi’ an and Datong.So it can be concluded that straw-bale has good energy-saving effects and universal adaptability for rural houses in cold and severe cold zones .
