Building heritage towards the future, through the energy efficiency

In period of globalization, where real-time sharing of what happens in the world, opens each scenario to broader visions, even the concept of heritage acquires a significance far beyond. The current events in the Middle East are bringing in the foreground the blind fury toward priceless treasures of history, and they offer us a reason to reflect on the role and the new meanings attributed to historical heritage. The preservation of our heritage becomes a moral duty to society in that it finds the sense of humanity. Recovering a historic building, currently, means to follow a long and complex way that from the reuse of its function, necessarily involves the redevelopment of its envelope, both in terms of construction, energy efficiency, in order to adapt it to the current paradigms of sustainable. The trial travels on two parallel tracks: preservation and requalification. All design decisions must be taken to reduce energy consumption, CO2 emissions and maintenance costs. Our research group has long been involved in studies on recovering of buildings located in the historic centre of Cagliari.
