Avaliação do conforto térmico em edificações de alvenaria com a inserção do telhado verde para a cidade de Toledo / PR

Abstract

With the passing of the decades, the increasing territorial occupation and human concentration in cities have promoted diverse forms of impacts to the environment, such as the significant reduction of green spaces between constructed areas. The decrease of these green areas can negatively affect the thermal comfort in microscale, generating expenses by turning on the air conditioner to provide a pleasant temperature. Thus, a study to verify the applicability and the effects of the green roof like a compensatory measure, becomes important. For this purpose, the objective of this study was to verify experimentally the variation of internal temperatures of a closed environment with extensive green cover in relation to a conventional roof. The analysis was made on the campus of the UTFPR of Toledo with 2 prototypes preexisted in the local, installing one of them with green roof and the other one with conventional roof – made by Roman ceramic roof tile. The green roof was consisted by a cover with layers: one of vinyl canvas for waterproofing, another one of expanded clay, substrate with soil and Zoysia japonic grass plaques, of the Poaceae family. The both prototypes were exposed to the same climatic conditions throughout the period of the experiment in order to verify the behavior of internal temperatures, measured by an Arduino Uno R3. The research presented the variation of the internal temperatures of the environment covered by the green roof and a conventional one, demonstrating the efficiency of the green roof.
