Pavimento poroso e vegetação : estratégias para melhoria do conforto térmico em áreas urbanas

Abstract

This study aimed to investigate how urban planning has influenced changes in the climate of urban areas and to correlate it with the windchill user from the external environment. Thus, this study aimed to evaluate the influence of the replacement of asphalt pavement by porous pavement and the deployment of woody vegetation in hygrometric term performance of the urban environment located in the parking lot of the College of Architecture Engineering and Technology (FAET) of the Universidade Federal de Mato Grosso in Cuiaba. Micrometereologic station was installed in the area chosen for registration of air temperature, relative humidity and surface temperature location. The data generated from this were used to calibrate the computer simulations of the current local environmental conditions, the replacement of asphalt pavement by porous pavement and the deployment of woody vegetation in the study region, performed with the aid of computer software called ENVI -met. We also evaluated the thermal sensations for the three types of idealized scenarios from the index UTCI (Universal Thermal Climate Index). These data indicate that the replacement of porous asphalt pavement the pavement results in a decrease of 4 ° C in the surface temperature of 0.56 ° C temperature reduction of air and 2.36% increase in air humidity. The analysis of thermal sensation by UTCI index indicated that there was no significant change in thermal sensation felt by pedestrians by the introduction of porous pavement. In the case of introducing more vegetation, the improvement in thermal sensation is felt only in places where there is shadowing by the vegetation.
