Project Description

Light Triangle It is the right of every living being to make sufficient use of daylight. Increasing housing development in cities reduces buildings' daylight savings and green areas. Therefore, it is necessary to produce a solution to such problems within the building itself. In order to find a solution to these problems, we tried to climatize and design a shell for the 24-floor (73 m) building in Istanbul. This structure includes residential-office-commercial functions. This shell that we designed enables to benefit from daylight adequately and in a controlled manner. At the same time, it tries to interact with nature again with its green areas and promenad. In addition, there are green and open-closed common areas where some floors can be emptied and other people can interact. When designing the shell, sun and wind densities were taken into account. Since the wind density is high in the southwest and northeast facades, closed areas are designed, while in the other direction, open areas are designed. On the south side, there are lighter and green areas for natural lighting. Natural air circulation is provided with openings in the building. In some regions, a greenhouse effect has been created. The triangular shape in the formation of the shell was chosen to transmit light more effectively and increase reflectivity. The aim of this project is to spread the light more gently and create a strong shadow. The diffusion of light in this way ensures that the entire area is rhythmically illuminated. In addition, this shell prevents overheating and uncomfortable direct light, providing light comfort. In architectural design, it was tried to increase the light performance with glasses of different colors. The dimensions and occupancy rates of the triangles that make up the shell have been adjusted according to the intensity and direction of the light. The material of the triangular glass used was chosen to increase the reflectivity. Thus, when the light passes through the glass, it breaks and creates shadows of different colors.
