Abstract
The notion of green cities is not green enough. There is a necessity to readapt consumption modes and rethink urban spaces in order to ensure the long-term viability of the built environment. Urban agriculture on roofs could play a great role in this transformation process. The question is: where and in what conditions would rooftop gardens have the most significant and positive influence on our existing urban system? This chapter presents a method, using Geographic Information Systems (GIS) and parametric modelizations, which provides an effective planning strategy of the green corridors network within a city. This interdisciplinary research is based on different parameters: the lead angle of the Viennese rooftops, the existing urban green spaces and the pollinator’s flight foraging distance. After importing the suitable rooftop surfaces into Grasshopper (Algorithmic modeling for Rhinoceros 3D, a CAD software), the model identifies the key surfaces capable to create large green corridors network and to connect existing green spaces in Vienna.

I would like to thank my Professor, C. Achammer for his supervision and his precious advices. Appreciation is also given to the Magistrate 22 of the city of Vienna for providing me the necessary Data to begin the study. A lot of the inspiration was drawn from my colleague Rüdiger Suppin with whom I could learn and develop this Grasshopper modelization.
