Improving indoor thermal comfort and reducing building energy consumption are the main ways to realize sustainable development of buildings. In view of the phenomenon of indoor overheating in traditional buildings in Qinba mountain area in summer, it was proposed to add sunshade components to the south-facing Windows for improving indoor thermal comfort. Ecotect software was utilized to study the influence of common shading components and shading louvers under different parameters on solar radiation in the south-oriented window. The results demonstrated that the shading louver has the best shielding effect on the integrated radiation. Finally, ANSYS.CFX was used to study the influence of shading louvers with different blade widens and angles on natural ventilation. Considering the influence of louver parameters on radiant heat gain and natural ventilation, it was recommended to choose louvers with a width of 200 mm and an Angle of 30°, which can effectively block 70% of the solar radiation heat gain of the south window and increase the ventilation potential by up to 15%.
