Abstract: In summer hot and winter cold climate zones, building energy behavior includes space cooling and space heating, resulting in confliction for determination of shading system. The building energy consumption assessments in this work were performed for the typical Chinese courtyard buildings situated in Sizhai Village. Taking into account the combinations of different types of shading device (3 types, i.e., overhang, buildings around the courtyard and gird slats), and variables of shading configuration (the depths of overhang, dimensions of courtyard and widths of grid salt were all assigned with 3 given variables), as well as building azimuths (4 categories, i.e., building azimuth intervals of south, north, east and west), a total of 252 (3 × 3 × 4 + 3 × 3 × 3 × 4 + 3 × 3 × 3 × 4) simulation runs were conducted. In consideration of the Sizhai's climatic features, the strategy of shading system with two-three configurations combinations (including 27 test scenarios) was proposed, which is more beneficial to improve of the building energy saving potential. The research results show that the test scenario with the shading system of B1O3–B1O3G3 combination has the maximum energy saving potential, contributing to the energy saving rates of 3%, 2.6%, 1.7% and 1.4% for the south-facing, west-facing, east-facing and north-facing dwellings, respectively.
