With an ever-increasing concentration of people in cities, urban areas
have become the focus of several studies concerning sustainable development.
Brazilian cities, such as Curitiba, have been undergoing several measures
toward higher density, specifically through high-rise buildings. High-rise
developments can bring negative impacts on urban microclimate, reducing
access to sunlight and ventilation. This study aims to analyze the influence of
high-rise developments on solar access in a high-density downtown area. The
research is justifiable considering the importance of solar access for
maintenance of health and quality of life of people and due to the increasing
amount of high-rise and high-density developments in cities. The analysis was
made on plots and buildings located in a portion of downtown Curitiba, a
subtropical location with Koeppen’s Cfb climate type. We evaluate eleven
blocks located on both sides of a major street, which has been going through
changes in urban morphology. 2D simulations were carried out with Autocad
and 3D simulations with Google SkechUp for quantifying percentages of areas
receiving sunlight in different time frames on the winter solstice. Two scenarios
were analyzed: the current and a hypothetical situation considering the full
consolidation of the area. An analysis of shaded and sun-lit areas of the building
north and west façades in one of the blocks was additionally performed for the
current situation, with the quantification of how many hours a given façade
would be either totally or partly shaded. Results suggest that the percentage of
shaded areas on the blocks already surpasses 60% of the total area in plan
during all times of the day. In a future scenario, the percentage of shaded areas
tends to increase even more, with over 75% of the plot area in the shade. As a
conclusion, it is suggested that future high-density/high-rise developments and
the legislation concerning them take into consideration solar access. |
