Climate change and the need to reduce energy consumption in buildings are key topics in the political, scientific, economic and cultural debate. Since the academic year, 2010-2011, we wanted to make a debate and also our contribution with the first edition of the Master in Materials and Innovative Techniques for Sustainable Construction (MeTIES) University of Palermo together with the University Consortium for the University of Western Sicily and the Mediterranean Basin (UNISOM). The main objective of this Master is to form a professional generation who knows how to master new technologies and to rethink the way to "build". All the students of the master, in different editions, have had the opportunity to improve skills acquired during the course in workplace. The aim was to contribute to the debate on possible ways to pursue sustainable development through the training of "operators" who have the ability to identify, develop and propose possible and concrete solutions for the energy efficiency of buildings. The book contains some solutions to the needs of a sector that will be increasingly at the center of the economic and political choices of the coming decades.
