Physical and Non-Physical Benefits of Vertical Greenery Systems: A Review

Urban green infrastructure improves the urban environment and enriches the lives of urban dwellers by positively affecting ambient temperatures, noise levels, and air quality, and creating an environment that promotes human health. Green technologies are increasingly used to increase green patches in urban areas. In this review of 108 vertical greenery publications, the potential physical and non-physical contributions of a subset of green infrastructure—vertical greenery systems—are presented. Most studies focus on how greenery improves the thermal performance of individual buildings and the potential energy savings, but non-physical benefits, such as health and well-being, have received little attention.
