15-Minute City in Urban Regeneration Perspective: Two Methodological Approaches Compared to Support Decisions

Among the interesting topics concerning urban regeneration, there are reconversion of disused public buildings and widespread neighbourhood facilities maintenance. The proposal of effective solutions about these topics is also a common subject for the construction of the 15-Minute City. Starting from a 15-Minute city review, a lack in the organic vision on the theme in the literature emerges, together with numerous interesting field studies, applications and experimentations in practice still to be deepened. The paper presents a comparison between different methodological approaches for the analysis of the accessibility of open spaces in order to support practitioners and policy-makers to improve walkability. The comparison between the two Italian case studies (Cagliari and Brescia) identifies the values of the systematic methodological approach based on description of context, design data collection, data analysis, indexing, to be used for co-construction of knowledge to support contemporary 15-Minute city (The paper is part of the activities of the Interdepartmental Center “Cagliari Accessibility Lab” of the University of Cagliari.).
