A development that is not compatible with the environment, economy and society is not sustainable. green roof and wall, as new approaches to architecture and urbanization, are based on the concepts of sustainable development to improve environmental quality, promote the economic and social conditions and, ultimately, sustainable urban development, because the implementation of green systems such as green roofs and walls, due to their environmental, economic and social features and functions, improves living conditions and realizes the goals of sustainable urban development; therefore, the establishment of green urban systems, due to their impact on urban life quality and sustainable development of the city, are worth exploring, and it is imperative that the green roof and wall issue is considered as one of the sustainable approaches to urban development. The purpose of this study is to examine how implementation of green systems impacts sustainable urban development. Hence, in the present study, the relationship between sustainable development pillars with green roof and green wall systems is investigated in cases such as flood management, reducing the effect of thermal islands, energy storage, filtering pollutants and reducing carbon dioxide, creating sound insulation, creating a natural ecosystem, food production, job creation, reducing exploitation costs against creating social interaction. The approach governing this applied research is qualitative. The research method is descriptive-analytic and collection of required information is based on theoretical concepts collected by the library method from books, articles and websites. Finally, considering the impact of green systems on sustainable urban development that is included in the findings of this study, executive suggestions for sustainable urban development are proposed by the environmental, economic and social functions of the green roof and wall.
