The sun-shading design was carried out based on a comprehensive building in a cold region. The reasonable building sun-shading design method in combination with the regional and facade characteristics in the cold regions is discussed, meanwhile, the unit-area refrigeration power consumption of the room and the annual building energy consumption before and after sun-shading setting are analyzed with simulation software. It is proposed that in the cold regions, designing sun-shading reasonably can reduce air conditioners energy consumption in summer, improve the indoor thermal environment and increase the indoor comfort level. This research can provides a technical reference to promote the sun-shading and building integration design and application in the cold regions.
