The subject of daylight has long been studied and tested by researchers and designers in various aspects, including schools. In the educational environment, providing a suitable comfortable space for individual’s academic achievement is important. Creating visual comfort and increasing the efficiency and motivation of education, are some of the benefits of classroom lighting control and preventing disorientation and glare in students' vision. This thesis examines the effect of the window's orientation and size, and a variety of sunshadings on the quality of daylighting in the classroom. To select the appropriate window design options for preventing glare in a school classroom in Tehran, the information obtained from climate simulations of Ladybug and Honeybee software in Grasshopper was analyzed and compared with the requirements and standards of international daylighting regulations. Simulations consist of three main steps: the first step involves analyzing window orientations, the second step is the affect of window to wall ratio(WWR) on glare and daylighting and the third step, includes the examination of ten sunshading types. The results show that in general, the amount of glare increases with increasing WWR, but this increase is varying in different directions. Also, in the southern direction, the depth of light penetration is at least twice as the north, and the average glare is 4% higher. These values were varied by simulating the types of sunshadings, and in one case, they reached a maximum of 89%. By combining the results, it is clear that increasing the depth of the light penetration does not necessarily increase glare, and the optimum shadings are combination of louvers with light shelves and skylights to prevent glare and also distribute the light to the depth of the room.
