Green roof have been investigated as a passive design strategy with various environmental advantages including energy efficiency. In this study the impact of the green roof on thermal behavior and reduce heat transfer of a green roof and to compare it with traditional roofs in reducing heat transfer in four different climate zones was analyzed. The simulation was conducted with DesignBuilder V. 4.5. The studied climates included humid climate represented by Rasht, semi-arid climate represented by Tabriz, tropical and subtropical desert climate represented by Yazd, and subtropical hot desert represented by Bandar Abbas. The thermal data for the green roof that were inputted into the software were composed of specifications of green roof plant species, thermal bulk properties, and green roof thermal parameters such as leaf area index and surface properties. The simulation was done on a residential building block for one year (four seasons) to specify the months in which the green roof could exhibit more optimal thermal behavior. The present study shows that the green roof in Rasht in April and July can help reduce heat loss. Furthermore, in Rasht, the value −0.02, Tabriz −0.87, Yazd −0.795 and Bandar-Abbas −0.335 will contribute to heat transfer. In the end, the green roof in Rasht can improve the reduce heat transfer in April and July.
