Hydroelectric Industrial Heritage: sinergical action for historic building innovative management. A starting project

A recent paper (Fasana S., Zerbinatti M., 2017) focuses about buildings for Hydroelectric power plants, grown up in firsts decades of the XXth Century, as material testimony of a great period of technical innovation and economic development. This industrial heritage consists in numerous complex of buildings whose unity of system suffers today a great decay. This constitutes a cost for managing stakeolder, generally represented by private-public partnerships. Some recent studies had focused on hydroelectric development as responsible of a great change Alps’ role (Azzoni G., 2017). Other studies (Vigliocco, Mattone et al. 2015-2017) reflect on a territorial scale, underlining as the most pervasive action towards the Alpine environment is represented by the hydraulic systems, widely distributed within the geomorphological conformation of the mountain territory. In order to return the complexity of the relationship between the natural environment and human intervention, the proposal (Vigliocco E., 2017) is a mutual promotion through a series of itineraries aimed at linking hiking tourism and hydroelectric systems. The phenomenon is more complex today because of the need to produce more and more energy from renewable sources: hydroelectric is the historical one and yet it remains the most achievable. So, thanks to incentive instruments, alternatively or in addition to repowering interventions on existing hydropower plants, many mini- or micro-hydroelectric plants have been designed. In any cases, regulations require that 3% of the investment be reinvested locally with the realization of environmental compensation works (D. Lgs. 29 dicembre 2003, n. 387, d 2001/77/CE). Even the most severe critics recognizes that main and complementary buildings for Hydroelectric power plants, although "questionable", arose as an extraordinary summary of the formal qualities of the old mountain dwellings "anthologies of the best built examples that can be found in each area" (Bolzoni). As a consequence, the main goal of the present study, is to identify and propose instruments for the effective management and reconversion of abandoned buildings, planning this interventions as forms of compensation to be activated concomitantly with the construction of new plants, or with the enhancement of the existing ones. Since, as mentioned, the hydroelectric infrastructural system manifests itself to the vast territorial scale, so that the action promoted is synergistic and effective on a large scale, it is necessary: - define "economically sustainable" methods of intervention, - set thematic guidelines and technical solutions supporting concerted actions at national (or regional) level. The method is under development applied on a first case study
