The solar energy potential of urban buildings is important for China's sustainable economic development. Previous studies have focused on creating regional solar maps or estimating the irradiation of building roofs. This study estimates the practical potential of solar energy in cities with a novel roof-facade framework. Improvements have been made to make it more practical by integrating roofs and facades, considering view shading effects, and correcting weather impacts. The developed framework was applied to calculate the solar energy potential for 10 cities in China on a microscopic scale. The annual solar irradiation ranges from 41.39 to 772.94 TWh, with an electric capacity of 6.21-115.94 TWh. A dataset of the annual solar irradiation for more than 1.44 million buildings of the 10 cities is now available as a free download (http://gis.nju.edu.cn/rs_01.asp?ID=74&type_1=425). The results can support decision-making related to reducing reliance on conventional energy sources and reducing carbon emissions. (C) 2020 Elsevier Ltd. All rights reserved.
