被动式设计是降低住宅建筑能耗的最经济有效的策略，它对气候和区域有很强的依赖性。选取中国25个具有代表性的城市进行优化分析。本文提出了一种将正交法和清单法相结合的方法，通过优化每个城市的7种被动式设计措施，即墙体厚度（WT）、屋顶保温厚度（RIT）、外墙保温厚度（EWIT）、窗户朝向（WO）、窗墙比（WWR）、玻璃类型（GT）和日光房深度/悬垂深度（SD/OD），探索如何将住宅建筑的能耗降至最低。经优化后，被动式设计可显著降低建筑年热负荷，对于拉萨等太阳辐射强度高的地区，可在冬季替代空调系统。结果表明，邻近城市具有相同的优化组合和相似的节能措施效果。在地图上总结了7个被动式设计区。根据本文提出的针对中国不同地区的优化方法，可以指导建筑师直接从地图上选择合适的被动措施，或者进行精确的被动设计处理。
Passive design, which has strong dependency of climate and areas, is the most economical effective strategy for reducing energy consumption inside residential buildings. A total of 25 representative cities of China were selected for optimum analysis. This paper presents an approach in which the orthogonal method and the listing method are integrated to explore how energy consumption is minimized in residential buildings by optimizing 7 passive design measures for each city: wall thickness (WT), roof insulation thickness (RIT), external wall insulation thickness (EWIT), window orientation (WO), window-wall ratio (WWR), glazing type (GT), and sunroom depth/overhang depth (SD/OD). With the optimization, the passive design could reduce annual thermal load of building considerably, even could replace air-condition systems in winter for the areas with high solar radiation such as Lhasa. The results reveal that neighbor cities have the same optimal combinations and the similar effects of energy-saving measures. A total of 7 passive design zones were summarized in a map. The architect could be guided in his choice of appropriate passive measures directly from the map or handling of exact passive design by the optimal approach proposed in this paper for different areas in China.
