Today, reducing energy consumption is one of the global concerns of preserving resources and the environment. The building industry is the main consumer of energy among all industries, so reducing energy consumption in this sector is important. This research aims to optimize the dimensions of windows in educational buildings to improve the quality of daylight and energy consumption, and for this purpose, one of the most important parameters, i.e. window-to-wall ratio, has been evaluated. Due to the parametric nature of the simulations, the software Rhino-Grasshopper plugin has been used to build the initial parametric model. Honeybee and Ladybug plugins have been used to simulate energy and light due to the use of the validated Energy Plus engine for thermal calculations. The results showed that the energy consumption of the building improved by about 12%, and the useful brightness of daylight improved by about 38% after optimization. The optimal size of the window-to-wall ratio for classrooms that received southeast and northwest light was about 25%, and for classrooms that received northeast light, about 20%.
