Clean Energy for All Europeans, Green Deal and Fit for 55 at European level and the Piano Nazionale Integrato per l'Energia e il Clima have identified essential decarbonisation goals that are achievable by broadening the audience of actors involved and the ability to innovate in terms of the evolution of products/services and production processes. In this sense, decentralised energy production technologies together with Renewable Energy Communities (RECs) and bottomup initiatives play a strategic role in the establishment of local energy systems. The objective of the paper is to illustrate these dynamisms within the territorial system, and the characteristics of local initiatives and RECs as means of energy transition and economic development.

The paper presents the intermediate results of the design experimentation of a Public Housing development in which the Renewable Energy Community model is an opportunity for energy transition but also for the needs of social inclusion and collaboration, which characterise the complex conditions of contemporary housing. Demonstrating the transcalar and multifunctional effectiveness of RECs incentivises their implementation, especially when a complex demanding framework is confronted with limitedly available resources. Hence, through a systemic approach, simulative methods and impact indicators, the extent of the contribution offered by the REC model was verified not only in terms of decarbonisation and climate neutrality but as an opportunity for eco-social regeneration.

In the contemporary context of the polycrisis, ways and criteria for sustainable urban transformation are discussed that shift the needle of ecological transition from building to city, towards energy self-sufficiency and social self-determination. Alternative forms of management, containment and production of clean and accessible energy from renewable sources are explored that have feedback in terms of process, design and social innovation. The paper aims to highlight the active and adaptive dimensions of technological design in its ability to support and promote behaviour favouring sustainable environmental transition.

The proposed decree of the Ministry for the Environment and Energy Security (MASE) encourages spreading self-consumption forms of energy from renewable sources, including Renewable Energy Communities (RECs). The paper proposes a mapping of the CERs already active in Italy, considerations on the main barriers that, at a national and international level, have hindered their diffusion, dwelling on the problems of compatibility in safeguarded and protected areas. Recalling projects and guidelines for installing photovoltaics in sensitive contexts, a first approach for a new CER in a UNESCO site is proposed as an opportunity to directly involve the Ministry of Culture as an actor in the energy transition processes.
