Crisis of energy has been turned out into one of the large concerns in societies. One of the most effective solutions to reduce the energy consumption in buildings is green roof. Green roof is used as a passive technique in order to reduce the demand for cooling and heating energy in buildings and improve the quality of their surrounding conditions. In this paper, advantages of using green roofs were assessed and the findings of recent researches about the relationship between green roofs and energy consumption in buildings were reviewed. Results of reviewed studies show that thermal behavior of green roof is subject of different conditions like type and thickness of growing medium, leaf area index and density of vegetation, ceiling temperature transfer coefficient, R-value of roof, and climate of studied region. Finally, results of this study show that green roofs have a positive role in roof thermal behavior in different climates which the rate of their efficiency depends on the climate that they are located in.
