Rapid construction, intensive urbanization, developing technology, and the desire to live in comfortable and high-quality environments have increased the use of energy and caused environmental problems. As buildings and urban areas account for a significant proportion of overall energy consumption, priority should be assigned to energy efficient solutions in buildings and urban area design. One of the most effective ways to ensure energy efficiency in buildings is to use wind, which is one of the resources that comes to mind when it comes to renewable energy sources and that has not been widely used in buildings before. In this article, the use of wind as a roof-mounted wind turbine was examined and the results of the parametric computational fluid dynamics (CFD) study conducted in a city to analyze the effects of texture form, building height, building height/street width (H/W) ratio, and texture orientation of wind speed on the roofs were reported. The study was carried out for the city of Istanbul, Turkey, where urban transformation is very fast. The results of this study showed that among the developed urban texture alternatives, compact structure alternatives (row houses and 4-courtyards), provide higher wind speed than the alternatives with single blocks. When analyzing the urban texture orientation, it was observed that the wind speed on the roofs of the textures at an angle of 45 degrees with the wind direction (0 degrees, 90 degrees alternatives) was higher than a wind speed on the roofs of the textures parallel to the wind direction (45 degrees, 135 degrees alternatives).
