摘　　要：体形系数是反映建筑外表面积与其体积之间关系的物理量,体形系数对建筑的节能影响很大。体形系数越小,建筑的节能效果越好。工程实践中应尽可能减小建筑的体形系数,以降低建筑的能耗。减小体形系数应根据具体的情况,采取不同的方法,如减小建筑的平面形状因子,增大建筑的体量,选取合适的层数等。The shape coefficient is a physical quantity to reflect the relationship between the building surface area and volume. The shape coefficient greatly affect the building energy saving. The shape coefficient is smaller, the effect of building energy saving is better. We should as far as possible to reduce the building shape coefficient in engineering practice, in order to reduce the energy consumption of buildings. In reducing shape coefficient it should adopt different methods according to the specific situations, such as reducing building＇s plane shape factor, increases the volume of building, select the appropriate layers.
