A methodological framework for the implementation of urban living lab on circular economy co-design activities

Circular Economy (CE) has the potential to tackle many of the challenges we are facing nowadays. It represents nothing less than a paradigm shift, as closing and shortening material loops means adopting completely new ways of producing and consuming. In the European Union, CE is a key strategy to achieve climate neutrality target by 2050, to face the biodiversity crisis, to guarantee economic growth and social wellbeing, within planet boundaries, in accordance with the UN Sustainable Development Goals. Stakeholders’ engagement is a crucial point of the transition pathway based on a systemic approach through a co-creation process. Urban areas are the main field of the circular transition process in which all the urban actors, i.e., public institutions, academic and research bodies, economic operators, citizens and civil organizations, are involved. An effective operational tool to realize stakeholders’ involvement and co-creation processes is the methodological approach of Urban Living Labs (ULLs). Although ULLs have already been tested and implemented worldwide, there is no description of a step-by-step methodology to implement ULLs aimed at co-creation of project ideas on CE, to be realized in a specific territory. This paper aims to define a methodological framework for implementing ULLs focused on co-designing CE activities. The proposed methodology is based on four main phases: (i) scouting and analysis of the territorial context, (ii) listening and exploration, (iii) participation, (iv) execution. A detailed description of each phase as well as the first application of this framework in different urban communities are presented

La conservazione preventiva, programmata e partecipata dei beni culturali in ottica circolare. Casi studio e sfide aperte nel progetto Basilicata Heritage Smart Lab / Preventive, planned and participatory conservation of cultural heritage in a circular perspective. Case studies and open challenges in the Basilicata Heritage Smart Lab project

La conservazione preventiva e programmata (CPP) dei Beni Culturali risponde a molti dei principi dell’economia circolare, primo tra tutti l’allungamento del ciclo di vita, e può contribuire efficacemente alla definizione di nuove azioni di sviluppo e gestione sostenibile del patrimonio, dei territori e delle comunità. Sostanziandosi nella programmazione di attività di monitoraggio, manutenzione e miglioramento delle condizioni ambientali, attraverso l'efficientamento energetico e climatico degli edifici storici, la CPP è in grado di risolvere in ottica sostenibile numerose sfide, non solo di conservazione, ma anche di gestione e valorizzazione del patrimonio, fino a conseguire il riuso di strutture dismesse, diminuendo sia l’utilizzo di nuovo suolo da destinare al patrimonio costruito, sia l’utilizzo di risorse economiche legate a interventi di restauro, scollegati da una programmazione strategica di medio-lungo periodo. Questo contributo presenta in maniera integrata, interdisciplinare e sistemica, alcune sperimentazioni del progetto Basilicata Heritage Smart Lab sulla conservazione di siti rupestri e l’attivazione delle comunità territoriali nei processi di co-governance di un edificio pubblico nel sito UNESCO dei Sassi di Matera: due aspetti solo apparentemente distanti, che è necessario connettere per garantire una corretta attuazione della CPP.Preventive and planned conservation (PPC) responds to many of the principles of the circular economy, first of all the extension of the life cycle, and can effectively contribute to the definition of new sustainable development actions of the heritage, territories, and communities. By substantiating itself in the planning of monitoring, maintenance and improvement activities of environmental conditions, through the energy and climate efficiency of cultural heritage and historic buildings, the PPC is able to solve numerous challenges from a sustainable perspective, not only of conservation, but also management and valorisation of the heritage, to the point of achieving the reuse of abandoned structures, reducing both the use of new land to be allocated to the built heritage and the use of economic resources linked to restoration interventions not linked to strategic planning. This contribution presents in an integrated, interdisciplinary, and systemic way, some experiments of the Basilicata Heritage Smart Lab project on the conservation of rock sites and the activation of communities in the co-governance processes of a public building in the UNESCO site of the Sassi di Matera: two aspects that are only apparently distant, which must be connected to ensure correct implementation of the CPP
