中文摘要：

通过对长沙市居住建筑热工参数调研分析，节能空间很大。通过建筑朝向控制和围护结构热工性能提升可以显著降低居住建筑能耗。体形系数≤0．4通过提高围护结构热工性能和设置活动遮阳，可以实现低能耗的设计；体形系数超过0．4，且窗墙面积比较大时，调整热工设计参数难以实现低能耗设计，需同时提高围护结构热工性能及空调性能。

英文摘要：

Through the analysis on the investigation of changsha city residential building thermal parameter, energy saving space is very large. Through building toward control and envelope thermal performance improvements can significantly reduce energy consumption of residential buildings. Shape coefficient of 0.4 or less by raising the envelope thermal performance and setting activity sunshade, can realize the design of low energy consumption; Shape coefficient over 0.4, and the window wall area is relatively large, the adjustment of the thermal design parameters are difficult to achieve low energy consumption, needs to increase at the same time retaining structure thermal properties and performance of air conditioning.
