BIM and the construction sector have long been an inseparable pair: in many European Countries it is a consolidated practice while in others there is a big debate about it but. Although there are important signs of a turning point, it still does not seem to be really feasible. In Italy, the leverage for transformation is certainly the public works sector, but this is not enough: to really talk about a whole digitization of the AEC sector, it is necessary to “attract” the private sector, where more than 50% of investments are invested.

Starting from the strategic initiative presented in 2020 by the European Commission and entitled “A wave of renovations for Europe: greening buildings, creating jobs and improving lives”, Member States are now committed to stepping up efforts to renovate their building stock, with the precise goal of achieving climate neutrality in 2050. With the aim of exploring the potential appeal of incentive measures, the paper started with some considerations on the use and ownership of the building stock in Italy, frequently with a lack of maintenance.

This paper introduces actual considerations for the progressive disuse of residential space in the Alpine territory, considering possible actions. Nowadays, the building complexes built around the 1960s and 1970s (a symbol of mass tourism) are suffering and searching for a new identity. The generation of owners who bought them has aged and the propensities of the new generations for holiday in those places has changed, which means fewer opportunities for leisure, particularly in the winter.

The global climate emergency has among its main causes the emission of large quantities of CO2 du...e to human activities. There are many policies implemented so far worldwide, but as the Union Square climate clock in the heart of Manhattan highlights, a greater effort is needed.

Although the theme has been studied for more than a decade, the green transformations of building...s are limited in practice and often new buildings, by large private or public estates, promoted and publicized it to gain public support. Is it possible to think about a widespread action to "green" our cities?
