User Engagement Through Perception of Vertical Greenery: A Case Study in Milan

The fast urbanism activities increase the impacts of challenges that are faced in the built environment include environmental, economic, and social prob lems. These problems have made sustainability an obligation, and Nature-based Solutions (NbS) and people engagement keys factor for mitigation. Together with Green Infrastructures (GI), NbS can offer several benefits to help multi-scalar impacts reduction in urban areas. Both horizontal and vertical surfaces of a build ing i.e., green roofs and green walls respectively, are recently considered among GI. Vertical Green Structures (VGS) is relatively new and still under develop ment. Hence, more research is needed on these systems to understand the benefits better and to highlight the existing the research needs. These VGS can offer both direct and indirect versatile benefits with the potential to contribute to robust and resilient cities through improvement of human health and well-being. This study focuses on perception of wellbeing deriving from a VGS installed in a case study in Milan i.e., at two university buildings in the campus. A questionnaire is pre pared and circulated among the users of these buildings to understand how they interact with the installed Vertical Green Structures, as well as how they per ceived and understand the VGS. The stages of social involvement and social ben efits in relation to the installation of VGS are discussed with the outcomes from the survey analysis.
