Building climatic zoning under the conditions of climate change in China

A Case Study of Refined Building Climate Zoning under Complicated Terrain Conditions in China

“…When only 34 national meteorological stations in Chongqing were used for climate zoning for building thermal engineering design, only two stations, Chengkou in the northeast and Youyang in the southeast, belonged to the mild zone (MZ), and the other 32 stations belonged to the HSCWZ, according to the zoning results based on China GB50176-2016 ( Figure 5 a); this result is largely consistent with earlier research findings [ 30 , 31 , 32 , 33 , 42 ]. After that, the entire Chongqing area could no longer be categorized as the HSCWZ but could instead be divided into three sorts of areas: CZ, HSCWZ, and MZ based on high-density observation data from 1908 meteorological stations ( Figure 5 b).…”

“…Five stations in Chongqing belonged to the HSCWZ from 1981 to 2010, and one station (Youyang) belonged to the MZ. In order to analyze building climate zoning across time, Cheng et al employed 2479 meteorological stations across China between 1961 and 2015, including 34 national meteorological stations in Chongqing [ 42 ]. “Spatial distributions of the climate zones for the periods of 1961–1990, 1971–2000, 1981–2010, 1991–2015, respectively” can be found in reference [ 42 ].…”

“…According to the results based on China’s GB50176-2016 and previous studies [ 30 , 32 , 33 , 42 ], the whole Chongqing area belonged to the HSCWZ. However, the terrain in the Chongqing area is complicated, and the three-dimensional climate characteristics are significant.…”

“…Second, the primary standards for China’s building climate zoning are introduced. The main primary zoning indicators in the Code for thermal design of civil buildings (GB50176-2016) were used for zoning in the study of building climate zoning in China conducted by Bai et al [ 31 ], Cheng et al [ 42 ], and Liu et al (2020) [ 32 ]. Primary zoning indicators and design principles of China’s Code for thermal design of civil buildings (GB50176-2016) can be found in reference [ 36 ].…”

“…(3) Using data from dense meteorological stations, the main indicators of the primary zoning of the Chinese Thermal Design Standard for Civil Buildings (GB50176-2016) were used for building thermal design climate zoning in Chongqing. This study’s Chongqing zoning results were compared and evaluated, and the causes for the variations between them and those from previous research [ 30 , 31 , 32 , 33 , 36 , 42 ] were examined. The potential energy saving percentage of new public building construction was then originally evaluated based on China’s national standard “General code for energy efficiency and renewable energy application in buildings” (GB 55015-2021) [ 44 ] utilizing the modified zoning results of our study.…”
