宁夏地区乡村民居节能设计研究

Energy efficiency of rural dwellings in Ningxia Hui Autonomous Region

为改善宁夏乡村地区居住建筑室内冬季热环境,达到建筑节能65%的目标,对典型传统民居进行了调研和围护结构能耗分析,发现了民居建筑耗能的主要薄弱部位.结合当地自然气候与经济条件,从建筑功能布置与空间组合、太阳能资源利用和围护结构构造等方面出发,提出整体式的建筑设计改进方案,并通过能耗分析计算新方案的热工性能与室内热环境质量,证明了在宁夏地区通过合理的设计农村住宅也可以达到提高室内热舒适和节能的目标.

In order to improve the thermal environment and reach the energy efficiency goal of rural house in Ningxia Hui Autonomous Region,the paper investigates a typical traditional vernacular,analyzes the index of heat loss of building envelop and discovers the main weak part in the building affecting on the energy consumption.Combining with the local conditions of climate and economy,this paper put forward the integrating designing project,including the function layout,room combination,solar energy utilization and construction of building envelop.A new project for improving the indoor thermal comfort and saving energy was given in this paper.The index of heating loss of two rural buildings are calculated in order to verify the effectiveness of the new project.At the same time,it is bproved that the improvement of the thermal environment and 65% energy efficiency goal can meet with by appropriate architectural designs.
