According to the over standard of the shape coefficient in the energy-saving calculation of the residential buildings,the paper analyzes the relationship between the residential building shape coefficient and architectural energy-saving by considering the design size of the building,the selection of proper length to width ratio,and daily radiation heat energy,and provides the design methods for the optimal energy-saving shape of the residential building.%针对住宅建筑物节能计算中出现的体形系数超标现象,从考虑建筑物设计尺寸、选择适当长宽比、日辐射得热量等因素出发,分析了住宅建筑体形系数和建筑节能的关系,给出了住宅建筑最佳节能体形的设计方法。
