DESEMPENHO TÉRMICO DE TELHADOS VERDES: AVALIAÇÃO COMPARATIVA DE SISTEMAS CONSTRUTIVOS

This study assessed the thermal performance of different Green Roof (GR) models compared to a conventional ceramic roof (CCR) in urban settings. Four roof prototypes were tested: Conventional Ceramic Roof (TV), Conventional Green Roof (TVC), Tray Green Roof (TVB), and Alveolar Green Roof (TVA). Thermal measurements were taken under varying climate conditions to analyze internal and external temperatures. Results showed that Green Roofs, especially the AGR model, performed better thermally than CCR. They maintained lower temperatures on hot days and more stable indoor conditions on cold days, enhancing thermal comfort. Vegetation such as Emerald Grass played a key role in cooling and reducing the urban heat island effect. The TGR and AGR systems also included drainage layers and water reservoirs, which improved thermal efficiency, reduced irrigation needs, and contributed to stormwater management. These features support both environmental sustainability and building resilience. Overall, Green Roofs proved to be a viable and effective solution for improving urban thermal comfort and reducing environmental impact. Future research should explore their performance in different climates and cities, as well as their long-term economic and social benefits.
