Avaliação do índice de conforto térmico em pontos representativos da malha urbana da cidade de Bayeux (PB)

Abstract

The Disorganized urbanization and how different transformations without use and land cover can modify the payment of energy in the terrestrial surface of urban areas, thus altering its thermal field and the conditions of environmental thermal comfort in these areas. Such changes in the energy balance of the cities' atmosphere can directly affect the local climatic conditions and the environmental thermal discomfort in these environments. In this context, the main objective of this work was to calculate the thermal discomfort index (IDT) at some points representative of the urban fabric of the city of Bayeux (PB). To carry out the research, three representative points of the city's urban network were selected for measurements of temperature and relative humidity in two different periods: dry and rainy. Measurements occurred for six months uninterrupted in the experimental samples through the use of thermohygrometer instruments of the HOBOS (Model U-10). Norder to analyze the thermal discomfort, the Thom Thermal Discomfort Index was used, with reference to the thermal comfort classification range for tropical regions adjusted by Santos (2011). The research shows that the points that present waterproofing soil cover material and low vegetation coverage are those that indicate higher IDT and temperature increase. The paper highlights the role of vegetation cover in climatic mitigation of urban areas. The results of microclimatic monitoring also clearly demonstrate that the areas with the highest vegetation coverage in their surroundings are those with the best conditions of environmental thermal comfort. In this way, the need to preserve green areas within the urban perimeter of the city of Bayeux (PB) and the environmental planning for a better territorial planning of the urban network of this city is highlighted.
