Life Cycle Assessment (LCA) for Water re use System of a Green Roof

Abstract

In urban contexts climate change and urbanization alter the correct management of outflows. The need to reduce CO2 emissions and increase the green areas presence is linked to forecast targets to facilitate the correct management of urban risks. To achieve these objectives the new technologies are available, such as green roofs, which are useful for reducing the impacts of climate change in urban areas and for the proper management of outflows, indeed, the green roofs can be connected to rainwater reuse systems. The collection and reuse water system can be studied using the Life Cycle Assessment (LCA) methodology. In this paper a sustainability estimate of the green roof and reuse water system is proposed in the Urban Hydrological Experimental Park at the University of Calabria (Italy).
