Effect of Green Roof in Thermal Performance of the Building An Environmental Assessment in Hot and Humid Climate
This study is an evaluation to the environmental impacts of green roof in thermal performance of the residential building in the hot and humid climate of Dubai, the United Arab Emirates. A computer simulation Ecotect is utilized to measure selected parameter: the solar radiation of the roof, which m...

| description | This study is an evaluation to the environmental impacts of green roof in thermal performance of the residential building in the hot and humid climate of Dubai, the United Arab Emirates. A computer simulation Ecotect is utilized to measure selected parameter: the solar radiation of the roof, which means to measure the heat transfer from the roof into the buildings and the other simulation, is with different mathematical formula. This study is carried out in four steps: first step, two types of residential buildings has been selected and simulating the internal solar gain of each building (building with conventional roof and building with green roof). The second step, simulating the U-value of both roofs (conventional roof and green roof), and find out which one has greater U-value and better insulation. Therefore, the internal solar gain of green roof with U-value has been smaller than conventional roof. The third step, find out the heat capacity of water and simulating the evaporation. And find out the benefits of evaporation. And finally, by creating a green roof layered with different thickness of the soil and local plants on the top of the buildings can add natural beauty on the building and human health. The first step concludes that by having the green roof on the top of the building can reduce the internal solar gain and heat transfer. The second step concludes that the U-value of green roof is lower that U-value of the conventional roof which means is better and the same time by having the green roof can maximize the insulation on the roof. The third step concludes that by having evaporation from the green roof can have reduced the cooling and minimized the internal solar radiation and finally by choosing the best thickness of the soil, vegetation and plants can achieve the best result for hot and humid climate such as Dubai. Finally, the study suggests guidelines and recommendations of benefits of green roof in hot and humid climate. Furthermore, it extends recommendations of configuration to other different climates besides the hot and humid and also effect of green roof in urban heat island in order to overcome the limitations of the proposal results. |
