Assessing Water Demand of Green Roofs Under Variants of Climate Change Scenarios

Green roofs are a resource for the city: they mitigate pollution, decrease the urban heat island effect (UHI), and regulate storm runoff. Within a climate change scenario, green roofs might instead become an issue, and in particular, in mitigating UHI at mesoscale level. The aim of the contribution is to define the water balance and thus the water consumption of a typical green roof, considering its variation when immersed into different climate scenarios that took place in the past five years (Linked with the following research projects: (1) Research title: 2016, Fondazione Minoprio/Politecnico di Milano, Dipartimento ABC (ongoing), Research type: Convention, Responsible: Matteo Fiori.
