Abstract
In hot climates, the work carried out has a significant share in reducing cooling loads within the scope of increasing energy efficiency in the buildings that are dependent on foreign energy supply. Based on stained glasses, this study has developed a program that allows glass surfaces to be designed with colored glasses depending on light transmission, absorption and reflection characteristics of different colors in accordance with the needs of the space as well as for use on facades with large glass surfaces that are exposed to the sun. The aim of this study is to find a multi-functional window designing system without considering the glass material. The colored transparent polymers are designed as the moving shaded elements placed on the window as window blinds. MATLAB is used in this study to write the program according to the climate data. The color, number of blinds and window prototypes are found by placing the data obtained through the laboratory studies of polymers in this software. Decreasing irradiance transmission in summer especially in A and B climate classifications is found to be important as the results show that the green and blue transparent filters transmit a minimum of 22 percent. The window prototypes are designed as two rows of blinds according to the window and the zone where they are located and placed in double or triple glazed windows. The simulation results of the Smart Window Design Tool (SWDT) can be shifted to any window geometry by defining the two season types.
