Abstract

Green roof research has grown rapidly over the past decade. The green roof has been proposed as a lasting move to reduce urban-related complications. The installation of green roof systems has been made as a specific measure to achieve a wider objective to enhance environmental sustainability. As one of the effective parameters on energy consumption, buildings have always been considered the attention of engineers to reduce the amount of energy consumption. In this study, the effect of different factors including effect of different facades on energy consumption has been investigated, for this purpose, the Energy Plus software has been used to model and perform sample building calculations at three parts of Tehran, Tabriz and Bandar-e-Abbas. The results of this study show that the city of Tehran will have the best performance in reducing energy consumption and it will be suitable for Tabriz city of color concrete, as well as in Bandar-e-Abbas, a warm climate representative, the use of travertine 1 is suitable.
