In this paper an analysis of green roof impact, a typical stormwater management facility constructed with the aim to reduce the volume of stormwater produced by traditional concrete roofs, is performed. As an example an application to the urban drainage network system of the University of Salerno Campus is illustrated. The main results show that the soil thickness and the water storage capacity are the most important factor affecting the soil water budget of the green roof, especially for event scale analysis. Depending on their values, a minimum and maximum reduction of stormwater production respectively of about 40% and 98% is provided by the green roof construction.

Abstract
In this paper an analysis of green roof impact, a typical stormwater management facility constructed with the aim to reduce the volume of stormwater produced by traditional concrete roofs, is performed. As an example an application to the urban drainage network system of the University of Salerno Campus is illustrated. The main results show that the soil thickness and the water storage capacity are the most important factor affecting the soil water budget of the green roof, especially for event scale analysis. Depending on their values, a minimum and maximum reduction of stormwater production respectively of about 40% and 98% is provided by the green roof construction.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
