UMA REVISÃO PRELIMINAR SOBRE A INFLUÊNCIA DOS MUROS NO COMPORTAMENTO DA VENTILAÇÃO NATURAL EM EDIFICAÇÕES

Abstract

In tropical regions, natural ventilation is an essential strategy for obtaining thermal comfort conditions and improving air quality. However, external components near the building, such as boundary walls, limit the natural ventilation incidence. This study aimed to investigate the effect of boundary walls on natural ventilation behavior in buildings. A Systematic Literature Review was applied, and 23 studies were selected undertaken in the last 20 years (2000-2020). The preliminary results indicate that the airflow pattern represents the main scope of works. In contrast, thermal comfort was less analyzed. The studies were realized in different locates and climates, and most of the researchers used parametric analysis by computational simulation. The main parameters investigated were the boundary wall porosity and the front setback, and the comparative analysis used as main metrics the wind velocity and airflow visualization. The final results will be possible to obtain a general panorama of state of the art and identify gaps that direct future research on the formulation of strategy for improving building/adequation of boundary wall in architecture projects.
