草砖房在北方农村地区适宜性研究

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。

STUDY OF ADAPTABILITY FOR STRAW-BALE HOUSES IN NORTHERN RURAL AREA

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.
