A study on the measurement of the effectiveness of energy efficiency of green roof systems: Tehran examination

Cities have been transformed into inhabitants of densely populated areas, which have been home to mankind from the past to the present day, as a result of industrialization, technological developments and social changes. Cities, the environment with the negative effects of energy is consumed extensively, in the structure of many heat island, agricultural activity is not done, affected and affect social structures. As the negative effects of the changes in the cities on the cities during the process are not perceived or ignored in the process, today's cities evolved into complex structures that consume nature. Nowadays, the majority of the city's areas are composed of impermeable structural surfaces. This situation has a structure that disrupts the natural cycle of water. Cities, the modern basic living space of human beings, have become a threat to human beings, life and the world. Our era is facing the world and hence the problems of life, environmental pollution, global warming and climate change. This study provides an overview of two main directions; discuss the effects of green roof systems on urban energy efficiency and the city. The study is based on literature review and data on an application in Tehran. In this context, up to date researches, numerical inputs and findings of research have been utilized. In doing so, special attention was paid to the regional characteristics of the green roofs. In general, it increases energy efficiency, decreases the negative effects of urbanization. According to the results obtained from this study, the design and implementation of green roof areas in mega cities such as Tehran, as a state policy, is proposed as a solution for future air pollution, energy efficiency, global warming and climate change problems. can meet the needs of the area and provide valuable environmental, economic and social opportunities.
