Aims: Due to high building density and lack of adequate open space in large and growing cities, the possibility of developing green spaces as elements controlling air pollution and urban heat island has decreased. One possible solution is to use the vertical surfaces of buildings to develop vertical greeneries. The right choice of vertical greenery systems according to internal and external factors affecting the system is the key to their success and development. This choice includes the correct choice of each of the four components of the system, including plants, growing media, supporting system, and irrigation/ drainage systems.
Methods: In this study, the factors affecting the selection of these systems were collected and explained through field observation and review and analysis of previous researches and were divided into four general categories based on the effect on each of the main components. Then, through a questionnaire from green wall experts, the prioritization of these factors was evaluated using the Five-point Likert scale. The results of the questionnaire were analyzed by Kolmogorov-Smirnov, Cronbachchr('39')s Alpha, Friedman, and Spearmanchr('39')s correlation tests, and presented.
Results: The results showed that external factors: "budget", "type of selected plants", "type of vertical greenery system" and "climatic conditions (temperature and humidity)" and also the internal factor: "structural characteristics and building materials" have had the greatest impact on the choice of these systems.
Conclusion: Paying attention to the importance of each of these factors and the prioritizations can help in organized decision making and optimal selection of vertical greenery systems.
