夏热冬冷地区居住建筑被动式节能设计适用性分析

Applicability Research on the Passive Design of Residential Buildings in Hot-summer and Cold-winter Zone in China

被动式技术是建筑节能设计的有效途径。而城市的区域气候特征又决定了被动式设计在建筑中应用的时效性。针对中国夏热冬冷地区气候特征,选取上海﹑武汉﹑重庆﹑南京﹑长沙五个城市居住建筑能耗与热环境状况进行分析。在WeaTool计算分析基础上,提出了适用度概念,并针对五个城市在通风、降温、太阳辐射、围护结构方面可行的被动式技术适用度进行分析,讨论了五个城市居住建筑被动式设计的策略和方法。

As we all known that passive design is an effective way of building energy efficiency. However, different urban climate characteristics determines the effectiveness of passive design. According to climate characteristics of hot-summer and cold winter area in China, we chose five cities: Shanghai, Wuhan, Chongqing, Nanjing and Changsha, and analyze its residential building energy consumption and thermal environment conditions. Based on WeaTool calculation and analysis, Suitable Degree(SD) concept was put forward to study the applicability of the passive design. In addition, we analyze five citys’ SD of passive design technology from the aspect of ventilation,temperature, solar radiation and envelope. Finally we discuss the passive design strategies and methods of five cities’ residential building.
