Increased population and disorganized urbanization constantly threaten the space available for urban green areas, reducing permeable areas of the city and causing problems such as: floods, occurrence of urban heat islands and lack of water, decreased air quality. Therefore, green roofs appear as a solution to minimize these impacts. In this sense, the objective of this work was to evaluate the performance of the green roof as a good thermal insulation that provides environmental comfort for the inhabitants of the building. To enable the reduction of natural resources and pollution, the Life Cycle inventories were compared to verify which system has the lowest impact on the environment, and thus allow the use of new projects with green systems . The studied green roof had 23.01 m2, and is located in the municipality of Londrina-PR. As material for the filtration of the extensive green roof was used Geotextile BIDIM Blanket, MAPEI Mapelastic Smart highly elastic membrane used for waterproofing; expanded clay to the drainage layer; a substrate layer and a layer of vegetation composed of the plant (Arachis repens). Green roof temperatures were monitored from 03/29/2019 to 04/24/2019, 24 hours a day. Differences of up to 8.5ºC were registered between external temperatures in relation to the temperature sensor installed inside the house. On 04/23/2019 the external temperature was 30ºC and the internal temperature was 21.5ºC. The efficiency of the green roof in maintaining the thermal comfort inside the house can be verified through these temperature differences. This proves that the use of green roofs changes the internal temperature of the building by increasing the environmental comfort and thermal capacity of the green roof, also, the the green roof studied in this work presented itself as less impacting to the environment, compared to the conventional roof. |
