A green rooftop is a novel element in modern architecture, inspired by the sustainability concept developed for urban environment. It is used for increasing green space per capita, improving environmental quality, and sustainable urban development. Meanwhile, some factors hinder the development and utilization of these architectural elements in cities. In line with this research problem, the main objective was to identify and to prioritize the factors, limiting green rooftop development in Tabriz city, Iran, to recommend operational procedures and a method for sorting out the limitations and obstacles. According to the literature, reviews and experts' opinions through Delphi technique, first of all, five pivotal obstacles (factors), restricting green rooftop development, have been determined including "cost and investment" factor, "cultural and educational" factor, "scientific and technical" factor, "climatic and ecological" factor and, finally, "legislation and management" factor. Then, a sub-situated group of factors was prioritized within each of the major pivotal factors, using the analytical hierarchy process. Afterward, each factor has been investigated according to its effects and statistical significance for Tabriz city. Finally, the statistical significance (priority measures) was determined for the major factor sets. The final set of factors have been compared to the alternatives, considered around the world. This research attempted to spot out and identify major and serious bottlenecks facing green rooftop development generally in Iran and particularly in Tabriz. Some practical and concrete solutions were presented in this paper, especially offered for the developing countries.

伊朗大不里士屋顶绿化障碍的优先排序和分析

绿色屋顶是现代建筑中的一个新元素,其灵感来自为城市环境开发的可持续性概念。它用于增加人均绿地面积、改善环境质量和可持续城市发展。同时,一些因素阻碍了这些建筑元素在城市中的开发利用。根据这个研究问题,主要目标是确定并优先考虑限制伊朗大不里士市绿色屋顶开发的因素,推荐操作程序和解决限制和障碍的方法。根据文献、综述和专家意见,通过德尔菲技术,首先确定了制约屋顶绿化发展的五个关键障碍(因素),包括“成本和投资”因素,“文化教育”因素、“科技”因素、“气候生态”因素,最后是“立法与管理”因素。然后,使用层次分析过程,在每个主要关键因素中对一组次要因素进行优先排序。随后,根据每个因素对大不里士市的影响和统计意义进行了调查。最后,确定主要因素集的统计显着性(优先级度量)。最后一组因素已与世界各地考虑的替代方案进行了比较。这项研究试图找出并确定伊朗特别是大不里士绿色屋顶开发普遍面临的主要和严重瓶颈。
