摘　　要：在《重庆市巴渝新农村民居通用图集》中选取典型设计方案,用清华大学开发的全年动态能耗模拟软件DeST-H进行供热供冷能耗模拟分析。模拟方案为变参数法,模拟出采用节能措施后的全年建筑能耗,并结合不同围护结构方案可能造成的成本增量,分析其技术经济性能。通过对各项节能优化措施进行研究分析、探讨,总结出适用于重庆新农村典型民居建设的最佳设计参数为:外墙外保温采用30mm膨胀聚苯板,主要功能房间外窗采用镀Low-e膜中空玻璃,其他房间采用普通6mm单玻;过渡季节加强通风;夏季空调温度设置为28℃,冬季采暖温度设置为16℃;建筑朝向为南北向。The DeST-H, energy consumption of developed by Tsinghua University, was used to analyze the Heating and cooling the typical design project obtained from the General Dwellings Atlas of Chongqing Ba-Yu New Rural Residential. The whole year energy consumption after opting energy-saving measures was simulated by varying the relevant parameters. Meanwhile, the technical and economic performance were analyzed by taking the cost increment into account which was caused by energy-saving measures. Based on the optimization results, the priority design parameters adapted to residential buildings of new rural development in Chongqing are summarized as follows： exterior wall thermal insulation with 30mm EPS board; the external window of the main function room with Low-e film hollow glass or others with ordinary single 6 mm glass; strengthened ventilation at over-season; indoor temperature in summer is set to 28℃, the heating temperature in winter is set to 16℃ ; building orientation is north-south.
