the concept of urban renewal had been having the classical meaning of "recovery", "re-use", and also "redevelopment" for many years. It has not been long time that this meaning has changed, or has begun to change, towards the Anglo-Saxon model taking in account the idea of an action that "determines an increase of economic, cultural, social values in an existing urban or territorial context." For instance, we can mention the regional law of 29 July 2008, nr. 21, of the Puglia Region, "Norms for urban regeneration", which states: «By this law, the Puglia Region promotes the regeneration of parts of cities and urban systems in coherence with municipal and inter-municipal strategies in order to improve urban, socio-economics, environmental and cultural conditions of human settlements "LEGGE REGIONALE 29 luglio 2008, n. 21: "Norme per la rigenerazione urbana". A similar concept was carried out by Lombardy Region by mean of its Regional Law of 26 November 2019 - n. 18 "Simplification and incentive measures for urban and territorial regeneration, as well as for the recovery of existing building heritage. Changes and addendums to the regional law 11 March 2005, n. 12 (Law for the Government of the Territory) and other regional laws "Legge Regione Lombardia 18/2019. This law defines the urban regeneration as "the coordinated set of urban-building interventions and social initiatives that can include replacement, re-use, redevelopment of the built environment and reorganization of the urban landscape by mean of recovery of degraded, underused or abandoned areas, as well as through the creation and management of infrastructure, green spaces and services […] with a horizon towards sustainability and environmental and social resilience, technological innovation and increasing biodiversity" (Art 2. L.R.18/2019). The same law introduces some rewards reserved to whom builds for social purposes. Moreover, these rewards are also reserved for those who carry on some particular implementation models. For instance, you can increase the volume of your building whenever "integrated safety systems and construction site risk management processes are applied; methods that are based on traceability and control activities, with particular reference to soil movement and waste traceability, based on advanced technologies", the increase in the building index is recognized in the art. 3 and these rewards are also given when technologies as geolocation, video surveillance and perimeter protection are implemented in order to prevent the "risk of crime during all phases of construction sites" La legalità per la rigenerazione urbana:
