The world today is more involved with the effects of non-renewable energies such as fossil and nuclear fuels. According to the official statistics of the International Energy Agency, about forty percent of the world's energy is consumed by buildings, so considering the energy crisis and its destructive effects on the environment and humans, finding a solution and a new idea for this is important, which means saving buildings. In energy consumption or even their self-sufficiency is the task of today's architect. It is generally accepted that daylight and visibility create health, comfort and a healthy work environment for users and therefore should be included in interior spaces. It is equally understandable that the need to control ventilation, reduce visual discomfort and glare for the users of spaces with daylight is necessary and to increase the comfort of residential residents, optimizing openings for better ventilation and proper efficiency of useful daylight in order to prevent health problems and Physical as well as economic efficiency is necessary. In order to save energy in this sector, the use of passive solutions to regulate the environmental conditions inside and on the other hand daylight plays a significant role in ensuring the health of the residents. Therefore, by examining the available resources in the field of reducing energy consumption and extracting the indicators and systems used in them, the simulation method with the Ladybugtools v1.6 plugin was selected on the Grasshopper software platform. By optimizing the window-to-wall area ratio (WWR), the results of two useful day lighting factors and building ventilation were optimized. The optimizations lasted for a total of 100 hours and 107 generations were produced. The optimal answer was found among the generated generations, which determined the optimal ratio of WWR for useful daylight at 40% on the north face, 10% on the east face, and 15% on the south face. and for the ventilation and energy sector of the building, 10% was determined on the north, 16% on the east, and 20% for the south. The results of the simulation were applied and its effect was eva‎luated using the simulator.
