Abstract

Green roofs such as green roofs (GRs) and green walls (GWs) have been one of the greatest attentions of architects and designers. In arid regions it is necessary to plant vertically, when urbanization continued due to the destruction of green spaces, it became very difficult to plant horizontally. In this regard, the methodology followed consists in evaluating the thermal effects of vegetation on the facade and the roof, covered with plants specific to the hot and arid climate. Then, using a dynamic simulation with Energy plus, we can measure the thermal impact of these green properties on the facade applied in an existing building. With a technical-economic analysis, we obtained a reduction of the various energy consumption values; cost benefits for green walls, and even reduce the effect of co2 emissions. Finally, we can effectively improve the exterior surface temperature, the thermal comfort inside the houses with low energy consumption thanks to the green facade.
