The energy transition path addresses integrated decarbonization strategies through energy production and storage towards ‘zero’ models, in line with current European directives. Actions can be taken at different scales, with an approach that sees emerging energy technologies and the organisational model of Renewable Energy Communities (RECs) as having the capacity to meet energy demand in an adaptable and decentralised physical-spatial framework. The contribution illustrates the results of the application of a workflow in the pre-design phases for the recovery of disused buildings and ruins as new energy devices within the cultural heritage of Bova (RC), case study of the NRRP—National Recovery and Resilience Plan research ‘Tech4You. Pilot Project 4.7.1 Open ‘Phigital Space’ user profiling platform for the advanced and dynamic codesign of built and ex-novo interventions’. The proposed workflow integrates advanced digital regenerative design tools for context analysis and modelling, enabling the visualisation of spatial data and supporting informed design, improving energy-environmental safety. In the pre-design phase, the use of parametric software allows the development of optimised energy scenarios, controlling efficiency and reducing carbon emissions, developing a pre-feasibility study of the energy performance of photovoltaics, adapting the project to the conditions of the urban cluster. The adaptability of the actions integrates the need for structural and climatic safety interventions with a view to sustainability. The formulation of the workflow integrates active and passive technologies for the optimization of dispersing surfaces with a form factor of less than 1. A model building with passive activity is used, evolving from positive to hybrid, through typological benchmarks that favour the integrability of the active system. The experimental results concern the optimization of building geometry and use configurations for the production and architectural integration of energy systems, in order to verify the feasibility of a hybrid ‘cluster’ design.
