Avaliação da influência do telhado verde, do tipo extensivo, no conforto térmico e na retenção de água pluvial em uma edificação, determinado pelo uso de um protótipo

Abstract

Researches on different technologies, such as green roofs, are of great importance to promote viable alternatives that minimize high temperatures inside buildings, in addition benefits the community by reducing heat islands and the possibility of flooding. Thus, this study pursued to evaluate the influence of a green roof on thermal comfort, through the use of a prototype. Temperature measurements were performed with a datalogger and a thermal stress meter. After obtaining the data, a typical summer day and a typical winter day were defined, according to NBR 15575 (ABNT, 2013), for the calculation and analysis of the delay and thermal amplitude and the average radiant temperature. Data on the collection and runoff of rainwater were not obtained, due to the low volume of rainfall at the study place, as presented by the Drought Monitor (ANA, 2021), however other studies were presented, in which positive results were obtained in this regard. The prototype presented satisfactory results for all thermal parameters, indicating that the green roof can favor thermal comfort in a building.
