With the progress of economy, technology, natural conditions and lifestyle, the protection and update of traditional residential buildings should adapt to the requirements of the new era and the changes of residents’ needs. However, the indoor natural lighting of most traditional residential buildings cannot meet the design standard of architectural lighting 300 lx. Building windowing is an important way to get indoor natural lighting, but improper windowing location, windowing area and window form may cause the room to lack privacy, cold air penetration, indoor thermal comfort decline and other problems, thus leading to the decline of indoor environment comfort. Aiming at comfort and energy saving, this paper puts forward the idea and method of optimizing the design of buildings. Taking the Minzhu community of Hengjiang town, a representative national traditional village in the south of Sichuan province as an example, this paper analyzes and studies the building window form with excellent comprehensive performance based on the local climate characteristics. The simulation software Ecotect was used to simulate the light environment of the optimized building and compare it with the pre-optimized architectural light environment. The results show that the optimized window opening form can not only make the indoor natural illumination reach the design standard of architectural lighting, but also make the indoor thermal environment, wind environment and visual field comfortable and have the effect of energy saving.
