| Resumo: | The study aims to determine the thermal performance of an experimental green-roof prototype that can be installed on pitched roofs of fiber cement corrugated sheets, widely used in our environment. Research results showed the advantages of using green roofs as a passive cooling device in the specific climate and weather conditions of a place such as Cali, Colombia, where roofs are the greatest source of heat gain. During the experimental phase, a control module and two test modules were built, where the green-roof prototypes were installed; surface temperature of the envelope and temperature and relative humidity of indoor and outdoor air were periodically recorded. Using a comparative method, it was possible to establish and quantify the positive effect of the prototype on the thermal performance of the envelope in local conditions, demonstrating its usefulness. |
