The University of Palermo has constructed an extensive green roof at the SAAF department (Figure 1). The green roofs, one of the natural measures for water retention among sustainable urban drainge systems, have the goal to retain precipitation and then later release it through controlled events in order to reduce the pressure on the urban network. The pilot system (6.5 x 3 m2), was built using the Harpo verdepensile commercial substrate, and will be used in order to study hydrological behaviour of a green roof in the Mediterranean climate conditions.
The experimental system consist of:
