大同市建筑节能的技术策略

Technologies of Building Energy Efficiency in Datong

将针对大同市寒冷地区的气候特点,利用建筑能耗分析软件DOE-2,建立典型建筑模型,分别从建筑体型系数、窗墙面积比、外围护结构传热系数以及大同市可利用天然冷热源和设备性能等方面对住宅节能的途径和方法进行分析探讨,进行在寒冷地区利用建筑节能的可行性研究。

This paper aims at the characteristic of the city of Datong, which locates in cold areas, and a typical model is founded by DOE-2 software which is used as analysis of the energy consumption in buildings as well. Then, the methods and approaches of energy construction in residential buildings are analyzed and discussed on the aspects of shape coefficient of buildings, area ratio of window and wall, heat transmission coefficient of building envelop, natural heat source and cold source in Datong and equipment performance. Finally, the sustainable research of energy efficiency in cold areas is studied in this paper.
