Abstract

The thermal performance and lighting of buildings are two critical factors in architectural design due to the need for energy consumption while establishing the residents' comfort. The design of the facade of the building as an external shell, which is the place of heat exchange between the building and the surrounding environment, absorption of solar energy, and penetration of light into the interior environment, is critical. Theoretical framework of the research was built on the highperformance architecture and daylightophil architecture theories for optimizing energy consumption in the building with especial focus on useful daylight illuminance (UDI), spatial daylight autonomy (sDA), annual sunlight exposure (ASE) and other critical daylight factors. The research method in this study was descriptive-analytical and considering the importance of educational spaces and the amount of energy consumption in this field, the central role and position of classrooms, in this research, the south facade of one of the classrooms of the Islamic Azad University of Semnan as a field study. It has been investigated and simulated in Rhino software and with Grasshopper, Ladybug, Honeybee, Energy Plus plugins, thermal performance analysis, and with the help of genetic algorithm method in the Galapagos component by changing the dimensions of the studied class windows, optimization has been The findings of the research shows that by optimizing the classroom, energy consumption in the south wall has decreased by 12% and more than 50% of the classroom environment receives useful daylight. Based on the LEED evaluation method, both indexes of spatial adequacy of daylight and annual direct sunlight received for the discussion of lighting in educational buildings have obtained the necessary points. The results show that the form and arrangement of the apertures in the south wall of the studied classroom are effective in receiving light and energy consumption, and the highest illumination and the lowest energy consumption are apertures with smaller dimensions and greater dispersion than the existing windows in They have the climate of Semnan city.
