Özet

The harmonious relationship of sustainable architecture with nature is one of the first things to be considered. In this regard, reducing the cooling load of buildings, especially in hot weather is very important. For this purpose, the use of different glass types in order to reduce the solar transmittance has become widespread. Among various types of glass used to reduce the solar transmittance, stained glass has been used for hundreds of years. The purpose of this article is to investigate the effect of paint level on transparent facade and reducing the cooling load of the building in summer. For this purpose, the level of these colors in glass has been modeled and optimized on two case examples of office buildings in the continental climate of Ankara. Simulations of these samples were performed for July and April using Rhino-grasshopper software. By optimizing the total minimum lighting energy and cooling load using the Galapagos plugin, the percentage of use of each color was determined. The obtained results can be evaluated according to the spatial orientation and the amount of radiant energy. According to the results, the area percentage of blue color in the window surface was found to be higher than other colors in the month of July (75% in the first case sample and 60% in the second case sample) and the purple color was found to be higher in the window surface as compared to other colors in April (30% in both samples). Yellow and orange colors in both samples had the lowest surface area percentage in the month of July (5% in both samples).
