Due to the employment opportunities in the cities after the Industrial Revolution, there has been intense migration from rural to urban areas. There has been a rapid construction process in order to meet the housing needs of the increasing population in the cities. Unplanned urban development has led to the destruction of green areas. As a solution to this problem, green roof applications in urban centers have gained popularity. Urbanization, which has been realized within the framework of the principles of sustainable urban development, has been a crucial requirement for the physical and mental health of future generations.
The aim of this study is to investigate the green roof awareness of the visitors of Zorlu Center located in Besiktas, Istanbul. Zorlu Center, which can be defined as mall and urban living space hosts about 30-40 thousand visitors per day with its shopping units, eating-drinking spaces, cinema, performance arts center, public green space and a public courtyard.

A field survey was conducted with 100 Zorlu Center users in different age groups, living in Besiktas district of Istanbul. In this context, a survey was designed to measure the impact of the green roof, which has gained public space function, on the imaginary expression of Zorlu Center.

The raw data collected by the questionnaire was evaluated by using the statistical program.
