Estudo do impacto dos parâmetros construtivos no microclima urbano em bairro residencial de Juiz de Fora - MG

Abstract

The present study analyzes the urban microclimate and the changes in urban legislation parameters and in the use of soil spaces that interfere on this microclimate. Therefore, the aim was to verify the influence and the impact of urban Laws on local microclimatic conditions and comfort of the habitants on a typical residential area of the central district of Juiz de Fora, Minas Gerais. The motivation is to contribute to a sustainable urban planning of the region. The studies were based on the analysis of three urban configurations: the actual built configuration, the maximum occupancy allowed by the current legislation, and the maximum allowed by the proposal amendments to this Law. Simulations using the software ENVI-met were carried out for the three cases cited above obtaining results for the variables ventilation, temperature and relative humidity. The results indicate that, considering the maximum allowed occupancy of the area, the current area is able to hold a higher urban densification, depending on architectural solutions to keep the thermal comfort within an acceptable level.
