Renewable Energy Sources Assessment and System Design based on Open Tools and Digital Twin Models towards Zero Energy Districts: the case study of Anzio Port
The present paper deals with an infrastructure digitization policy aimed at optimizing maintenance processes and energy efficiency to transform port areas in ZED (Zero Energy District). The Lazio Region started the process in 2020 for all its ports. Anzio started and developed as a pilot project as it is a particularly representative sample for the Mediterranean Sea reality due to its geomorphological conformation. The study aimed not only at developing energy-saving procedures and strategies but also at integrating production systems from Renewable Energy Systems (RESs) for sustainable mobility. In the article, these strategies described in detail and energy analysis is carried out, starting from the current state and demonstrating the potential energy self-sufficiency of the infrastructure. It also highlights the potential of the investigation utilizing a Digital Twin (DT) of the area, combining the possibility of BIM (Building Information Modeling) and GIS (Geographic Information System), comparing future scenarios even to varying scales to maximize the beneficial impact of energy efficiency measures
