Sustainable airports and NZEB: The real case of Rome International Airport

The paper shows and analyzes the energy efficiency solutions adopted to renew the terminal T3 of Rome International Airport at Fiumicino 'Leonardo da Vinci'. Such solutions put together the top-of-the-market energy technologies with the most innovative architectures and materials to renovate an old terminal transforming it into a Nearly Zero Energy Building (NZEB). For the new forepart of the terminal and for the new boarding area 'F', now under construction, a dynamic energy simulation has been performed using a software provided by the US Department of Energy (DOE) named Energy Plus, and its interface Design Builder. The tool makes possible to calculate the energy consumption of the two buildings and to assess the design in order to maximize energy efficiency and sustainability. The main results of the energy analysis are reported after detailing the case study.
