The design of windows can provide the proper lighting of the interior and create comfortable conditions to increase the efficiency of the building. Furthermore, in designing building façade articulation, it is important to consider the projection and indentation, therein. This study aimed to evaluate the optimum parameters of the window by measuring energy consumption and daylight quality in residential buildings. A room with a constant window-to-wall ratio of 30% and different windows angles with horizontal and vertical rotation around the orthogonal axes to the inner and outer edges of the wall in all four cardinal directions, with the hot and dry climate of Isfahan as the case sample was selected, and daylighting and energy were simulated for all situations. Considering the criteria of daylight and annual energy consumption as output variables window angle from inner-outer and outer-middle in plane mode the most optimized design options are south and west orientation with 4.81 and 1.6% energy conserve, and inner-outer angle in cross-section for east and north orientation with 3.71 and 3.49%, respectively. Low-emissivity glass performed better with a mean of 2.78% of total energy storage in optimal window angles and the southern direction window with 21% total energy consumption has been the most prominent.

窗户的设计可以为室内提供适当的照明，并创造舒适的条件以提高建筑物的效率。此外，在设计建筑立面的铰接时，重要的是要考虑其中的凸起和凹痕。这项研究旨在通过测量住宅建筑的能耗和日光质量来评估窗户的最佳参数。一间房间，窗与墙的比率恒定为30％，并且窗户的角度不同，并且在四个主要方向上围绕与墙壁的内边缘和外边缘正交的轴水平和垂直旋转，而伊斯法罕气候炎热干燥选择案例样本，并在所有情况下模拟采光和能量。以日光和年能耗为标准，以平面模式下的内外中间窗角作为输出变量的窗口角，最优化的设计选项是南北和西向，节能量分别为4.81％和1.6％，内外角为横向东，北向剖面分别为3.71％和3.49％。低辐射玻璃在最佳窗口角度下表现更好，平均占总储能的2.78％，而向南方向窗占总储能的21％最为突出。
