PROGETTAZIONE MULTI-SCALARE DI INFRASTRUTTURE VERDI-BLU: S-RGB (SAFE-REGENERATIVE & GREEN BLUE INFRASTRUCTURE) DESIGN

The ecological approach to urban planning has recently become one of the main interests in the international disciplinary debate, in response to new social demands: climate change, natural hazards, resource reduction and soil consumption. In relationship with the design field, there are attempts to define innovative approaches: in this paper, the research proposal focuses on "multi-scalar design", a practice capable of acting on open spaces, ecological networks and green infrastructures but also on the regeneration of neuralgic areas of the urban organism. The paper attempts to integrate the territorial vision offered by green infrastructures with the more focused approach of the urban acupuncture, revisiting this technique with an urban design perspective. Furthermore, the design of green infrastructures in urban areas acts mainly on public spaces by expanding their number and size, thus making maintenance and guaranteeing their usability even more complex. In other words, the safety of public spaces is becoming a central problem in urban policies and, therefore, the project proposal is completed by giving particular attention to the recent guidelines for the design of urban safety (European protocols, UNI standards, etc.). The idea of combining these approaches at different levels, from territorial to micro-urban ones (acupuncture) is defined in the "s-RGB Design" proposal (safe-Regenerative and Green Blue Design). The paper intends to raise the question of the design of urban green infrastructures, mainly in generally unsafe regeneration areas, and proposes some application examples developed in the didactic field. Very often these areas represent an opportunity for the development of new ecological networks, cultural routes, light mobility and new forms of urban agriculture, but the safety of the users must be guaranteed in the project. The ecological approach requires the selection of specific "hotspots" capable of triggering virtuous regeneration processes, paying attention to the safety of urban spaces for users. The proposed methodology aims to combine green infrastructure planning with a new safe urban acupuncture.
