GINNGER will ease the regeneration of neighbourhoods and built environments through the implementation of co-creation processes in heterogeneous stakeholders structures. This will facilitate the planification and implementation of actions in local environments, leading to a reduction of social, environmental, technological and economic risks thus to deliver healthy, affordable and sustainable built environments in EU. The project will create positive social impact in neighbourhoods by stablishing and validating the GINNGER co-creation methodology aimed at supporting decision-making procedures for regeneration actions. The co-creation methodology will rely on SSH innovations for social progress and the enhancement of public policies. The project will put special emphasis on the validation of the co-creation methodology in 6 pilots: P1. Langreo (ES), P2. Plovdiv (BG), P3. Massagno in (CH), P4. Murcia (ES), P5. Orte (IT) and P6. Paris (FR). Within these pilots, the co-creation methodology will support the implementation of 21 Regeneration Actions. Moreover, GINNGER will set-up a local figure called the Green Neighbourhood Facilitator, which will ensure that voices across pilots are heard and will lead the capacity buildings actions at local level. To complement the implementation of the regeneration actions from a technical perspective, GINNGER will develop and validate a digital toolkit to support the planification, implementation and operation of the regeneration actions. The digital toolkit will be composed by a total of 13 digital solutions grouped into four blocks dealing with Energy, Renovation, Resources and Mobility. As a result, GINNGER will set long-term strategies for the planification and implementation of cooperative models for neighbourhood regeneration, facilitated by the generation of 14 key exploitable results during the project. The implementation of such an ambitious project requires of a consortium of 24 partners from 8 EC member states.
