Extended data
Basic requirements of buildings in various districts
(1) 1. Building climate zone: including Harbin, Changchun, Shenyang and Hohhot. Buildings in this area must fully meet the requirements of cold protection, heat preservation and antifreeze in winter, and heat protection can be ignored in summer.
(2) Building Climate Zone II: including Beijing, Tianjin, Shijiazhuang, Jinan, Taiyuan, Zhengzhou, Xi and Lanzhou. Buildings in this area should meet the requirements of cold protection, heat preservation and antifreeze in winter, and some areas should take into account heat protection in summer.
(3) Three types of building climate zones: including Shanghai, Nanjing, Hangzhou, Hefei, Wuhan, Nanchang, Fuzhou, Changsha, Chengdu and Chongqing. Buildings in this area must meet the requirements of heat protection, ventilation and cooling in summer, and give due consideration to cold protection in winter.
Buildings in IIIA area should be protected from tropical storms, typhoons, rainstorms and salt fog. The roofs of buildings in the north of Zone IIIB should be protected from snow in winter.
(4) Class IV building climate zone: including Guangzhou, Hong Kong, Nanning and Haikou. Buildings in this area must fully meet the requirements of heat protection, ventilation and rain protection in summer, and do not consider cold protection and heat preservation in winter.
Buildings in IVA area should also pay attention to prevent tropical storms, typhoons, heavy rains and salt spray erosion; The buildings in the valley of central Yunnan in IVB area should pay attention to the crack resistance of roof and wall.
(5) ⅴ Building climate zone: including Guiyang and Kunming. Buildings in this area should meet the requirements of rain protection and ventilation in rainy season, but heat protection is not considered.
Buildings in VA area should still pay attention to cold protection; Buildings in VB area should pay special attention to lightning protection.
(6) ⅵ Building climate zone: including Lhasa and Xining. Buildings in this area should fully meet the requirements of cold protection, heat preservation and antifreeze, and heat protection is not needed in summer.
In areas ⅵ C and ⅵ B, attention should be paid to the influence of frozen soil on building foundations and underground pipelines, and special attention should be paid to preventing sandstorms. Attention should be paid to the lightning protection of buildings in the east of the international center.
(7) ⅶ Building climate zone: including Yinchuan and Urumqi. The buildings in this area must fully meet the requirements of cold protection, heat preservation and antifreeze, and some areas should also take into account heat protection in summer.
