Along with the growing territorial occupation and concentration of buildings in urban areas, there has been a significant reduction in green spaces in between the built up areas. The reduction of these green areas may negatively affect thermal comfort in a microscale, with a future expense being necessary a future expense is necessary to provide a pleasant temperature inside homes. This work aimed to present a comparison of the variation of the internal temperatures between a room with a roof covered with grass, forming an extensive green roof and a conventional roof of fiber cement. In order to perform the experiment two equal rooms were built with wooden naval plywood, differing only in the composition of their roofs. The green roof modules consisted of a wooden box, overlaid by a layer of asphalt blanket for waterproofing, a layer of expanded clay, soil and plates of Zoysia japonica from the Poaceae Family. Both rooms were exposed to the same conditions throughout the whole experiment in order to verify the behavior of the internal temperatures measured with digital thermometers. During the period in which the experiment occured, from 16 April to 17 July, it was observed that the room with green roof showed a lower amplitude of temperature change in relation to the room with fiber cement. That is, during times of increased solar radiation, the green roof showed a lower temperature, and during periods of little or no solar radiation, the green roof on most of the times didn't reach a temperature as low as the one in the room with fiber cement. It was also noted that the fiber cement roof tended to cool down faster, as the evening would fall. |
