The green roof can protect the roofing membrane from ultraviolet (UV) rays and prevent physical damage due to the degeneration of insulation and roofing materials. It can block solar radiation and reduce daily temperature fluctuations in summer and winter. All these benefits extend the life of the roof [19]. Heat gain and loss through a green roof is primarily defined by solar radiation from the sun. Green roof useful for reflecting solar radiation and reducing heat absorption by evapotranspiration. Additionally, it can minimize the amount of heat transmitted through the roof membrane through additional insulation. Determining green roof materials, foliage characteristics, and soil characteristics that affect the thermal performance of the roof is necessary for designers [20]. 1.2.3.2 Climatic/seasonal consideration: Solar radiation can change seasonally and in different locations, and can impact the thermal performance of green roofs and
