The regeneration of the existing city. Analysis of the environmental impact of building incentives

The contemporary city deserves and needs urban regeneration interventions, and this is only possible through integrated intervention tools to which is entrusted the task of accessing a broader notion of physical decay. They place at the center the citizens' right to quality of life declined in its various urban, social, economic and environmental aspects. Urban regeneration is still an open question and proof of this is the lack of a unified framework for this practice that must become one of the basic foundations for the governance of the contemporary city. Placing urban regeneration at the center of the sustainable development of the contemporary city implies a new way of imagining the growth of the future city. From the Aalborg Charter to the Toledo Declaration of 2010 and other measures that have indicated the strategic importance of urban regeneration in terms of ecological-environmental sustainability to achieve which requires an urban alliance shared by all the actors involved in the city-building process, based on consensus and legitimized by new forms of governance. The culture of urban regeneration must be affirmed and become pervasive first and foremost within public administrations at all levels - State, Regions, Provinces, Municipalities - but also in the business world, starting with the construction industry, and in the professions, and more widely among the citizens who live there. This research work provides a brief survey of the legislative evolution that has affected the theme of regeneration both at national and regional level. Over the last fifty years the process of evolution of this phenomenon can be divided into three phases:  1970s: Redevelopment of historic centers, regarding the desire to reaffirm their local identity and values.  1980s: Reclamation of brownfield sites, following the extension of state-owned areas that began to represent voids to be filled.  2000s: Redevelopment of residential neighborhoods from the second half of the 20th century built on the basis of low-quality construction, architecture and urban planning, in order to give them a new aesthetic appearance, revitalizing the area's image. Significant space will be devoted to an analysis of the environmental impact of tax incentives on the building stock. In recent years, tax deductions for building renovation, earthquake retrofitting and energy requalification have played an increasingly important role in the construction market. The aim of this research is to assess the effects of the aforementioned benefits, with particular regard also to the socalled superbonus: - on energy efficiency and environmental sustainability, in terms of reducing energy consumption from fossil fuels and CO2 emissions, as well as promoting energy autonomy from renewable sources, also in the light of the territorial distribution of the incentives and the distinction between main homes and others in residential construction.
