Buildings shading in cities are crucial elements in shaping inviting public spaces adapted to climate changing. In view of the increase in the buildings height defined in the last update of the urban legislation in the city of Curitiba/PR that took place in 2019, this study aims to analyze the impact of shading from surrounding buildings from simulations in three squares located in different zonings not consolidated or expanding which allow buildings with at least six floors. The method composed of different steps from open data, results in different maps for the summer and winter solstices, and equinoxes. The analyzes demonstrate that when the simulation is carried out considering the buildings height with the acquisition of constructive potential, the shading impact on public spaces is considerable, especially in the winter solstice. Considering Curitiba as a city characterized by cold at that time of the year, ample solar access in public spaces can be recommended. It is argued that the study of the impact of buildings shading is a possibility for delimiting more restrictive indices in urban planning processes.
