Nowadays, saving energy is more important than past due to the population growth and utilizing more resources as a consequence of it. Given to 30-40% of energy consumption in the buildings and existing potential to save energy and the main role of window in the energy consumption in buildings, this study attempts to assess the effect of window, its shape, proportion and type on the heating energy consumption and the effect of shading devices on the cooling energy consumption in residential buildings in Mashhad city. For this purpose, a model with the area of 250 m2 was defined by Design Builder software, in which two variables of the direction and the percentage of the window wall ratios were considered. Then, by keeping window wall ratios constant, the windows’ proportion in wall was assessed and finally the effect of hangover on the cooling of building was simulated. By reviewing analyses, it is observed that the shape and dimensions of the windows to the East and South have significant effects on the heating energy consumption and also the use of shading devices above the windows to the East, West and South is recommended.
