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.
