A multi-criteria analisys tool for rethinking cultural heritage in evolving cities. Metabolistic approach.

Collective memory and individual identity in society are increasingly losing their importance in contemporary cities. Both material and immaterial heritage has to become a strategic element by which a citizen can recognize himself in the spaces of his everyday life. In 2018, the municipality and universities of Barcelona provided a moment of international consideration - using the hackaton instrument. This reflection was focused on the infrastructural heritage represented by the “Rondas” – originally developed as a connective element while today being seen as separating structure. The question was how this ring road might evolve during the next twenty years, forming new patterns between citizens and transportation. The transdisciplinary approach by a team of the Sapienza PDTA department has produced a multi-criterial analysis tool based on economic, functional and social indicators, which reconsider the infrastructure as connective element. Using “Ronda” as a model case, the paper looks at the metabolist model, rethinking it as an updated element of multi-level connection and proposing a neighbourhood future vision by inserting naturalistic-technological, urban-planning and territory-identity solutions. The aim is to demonstrate how the developed methodology can be reproduced in other heritage evaluation scenarios, adapting variations of indicators in the analysis, all the while being a generative and dynamic tool with data visualization techniques as an integrated element
