Increasing urbanization causes environmental problems to become more frequent and, therefore, alternatives such as the use of green roofs are important in the environmental improvement of urban centers. The present article has evaluated the temperature in different green roof systems prototypes (Systems: MacDrain, Modular and FLAT) cultivated with Callisia repens, to quantify the improvement related to the thermal comfort that these systems provide, comparing them with each other and with a control system. The results showed that the systems are able to attenuate the solar radiation with higher temperatures, reducing the transfer of heat from the external environment to the compartment below the prototypes. On the other hand, at night, normally with mild temperatures, the systems work by keeping the heat absorbed during the day in the compartment below, isolating the loss of heat. Statistical analysis has been made and the control prototype presented a significant difference in relation to other systems, showing the potential of green roofs in thermal insulation.Downloads
