In order to establish a simple and effective solar heating potential evaluation method based on building shape elements, taking Ejina Banner and Xi'an as examples, a study on the potential of solar heating in western China was carried out. The height-to-width ratio, height-length ratio, and south-facing window-to-wall ratio of the building are regarded as the key physical elements closely related to the heat utilization of solar heating. After orthogonal experiments, dynamic energy consumption simulation, and mathematical statistical analysis, building solar heating potential function based on building shape elements is obtained. By graphical expression of the function, it is found that increasing the aspect ratio and the south-facing window-to-wall ratio are conducive to improving building solar heating efficiency. Effective measures to improve the solar heating efficiency of buildings in Ejina Banner and Xi'an are given. This research is not intended to replace dynamic simulation tools, but to construct a simple thermal performance analysis method for solar heating design at the initial stage of building design.
