Climate change is restating the energy performances of buildings and urban textures. In order to eliminate the deviation caused by climate change, the relation between solar gain and urban texture has to be defined by the method which is taking future weather data for predicting building energy performance. Besides, the solar availability on façades which is influenced by the morphology of the urban texture, is strictly related to building energy performance indeed. The building energy performance is influenced by building related design parameters (building form, orientation, building envelope etc.) and by urban related ones (climate, aspect ratio etc). Therefore, it is worth further efforts to present the methodology with a holistic approach which enable to design buildings and urban textures according to this impending climate change. Within the scope of this this study, it is aimed to evaluate potential effects of climate change on buildings’ solar gains and energy performances in relation to urban textures. For this purpose, changes in buildings’ solar gains and energy performances in urban texture alternatives created for Istanbul where new urban textures are rapidly developed, are evaluated based on existing and future climate scenarios. Evaluation findings are intended to provide basis for future studies on building energy performance in order to prevent or minimize the long-term effects of climate change.
