The southern wall plays an important role on heating perfrmance and energy consumption of residential buildings. This study investigates the effects of southern wall angle, glass area and external canopy on heating perfrmance and energy consumption of a typical residential building in Yazd. Using causality method and thermal simulation by DesignBuilder simulator, we examined energy consumption in 33 situations under differnt angles of southern wall (from zero to 60 degrees), and under different glass areas on the surface. According to the results a southern wall with a maximum glass area, with external retractable canopy and with an angle of 15º, would reduce daily heating requirment and energy consumption of the residential building by 43% and 17% from 8 to18 o'clock, respectively. These figures would decrease to 9.1%, 6.7% respectively, for the whole day.
