Abstract

Expanding the range of human civilization and industry sovereignty, based on new technology and a tendency towards machine life, in tandem with the destructive and destructive effects of natural resources and vegetation, the conversion of arable lands and gardens to building structures, along with the increasing population growth in cities And environmental pollution has not only disturbed the balance of the ecological system and the power of well-being, but it has also created difficult conditions for human life. This has given rise to the issue of urban green space in recent decades and the search for new ways to address this need. Designing green spaces for a city or a neighborhood is by no means an accident. On the other hand, land is scarce and very expensive to create green space in cities. In this case, unused surfaces such as roofs can be used. Green roofing is one of the environmental technologies that is formed under natural processes and has been attracted in many countries in recent years. This study seeks to identify the challenges of green roofing in developing countries and compare them with developed countries. To this end, the challenges and barriers to creating a green roof are first identified and then weighted and weighted to gauge the importance of each. The results showed that the investment dimension is the most important challenge for the development and construction of green roofs.
