Recommending an Appropriate Type of Green Roof Taking into Account Urban Typology and Climatic Zoning in Iran

Population growth in the major cities of Iran has led to the limitation of land resources, higher consumption of nonrenewable sources of energy and many other environmental problems. The emergence of overly built-up urban areas and a decreasing amount of green spaces cause the appearance of an undesirable landscape within cities. Green roof technology is one solution for responding to environmental concerns in urban areas. This technology combines green spaces with buildings as private or semi-private spaces. Its successful implementation in different areas depends on the accommodation of green roof type technology within the environments and urban and building typologies in Iran. This paper aims to provide some recommendations for selecting the appropriate type of green roof and for implementing approaches that take account of the climatic zoning and urban situation in Iran. Two primary aspects that are considered are environmental and urban typology factors. The research method is based on the study of indicators related to each factor mentioned in different zones of Iran, thereby leading to a feasibility study for the application of green roofing in Iran.
