Arranjos construtivos urbanos: um estudo sobre a influência da configuração de conjuntos habitacionais verticais na qualidade térmica de edificações em Maceió-al

Abstract

In the low cost housing programs, the standardization and climatic inadequacy of design solutions have resulted in uncomfortable thermal conditions. The aim of this study was to evaluate the thermal quality of different urban design arrangements of vertical blocks dwellings destinated to the low income population in the city of Maceió - AL. The comparative, qualitative and quantitative analysis was carried through three different blocks disposed at different urban arrangement. The qualitative evaluation was based on bioclimatic attributes of the urban form and the quantitative one was based on indoor climatic monitoring, outdoor microclimatic measurements and further models simulation using CFD software. It was observed that the air temperature and relative humidity values corresponded up to 95,7% of indoor thermal discomfort hours. The results of models simulations have shown that, the factors that had most affected the studied thermal conditions had been: bad localization of the openings in relation to the local prevailing winds, bad distribution and orientation of the blocks in the evaluated urban constructive arrangements and little air porosity of the buildings. It is expected that these information could help future low-cost buildings projects in hot-humidity climate cities as Maceió-AL.
