## 5 Conclusions  
This study, focusing on the energy performance of a solar PV system for the Olympic Stadium's suspended roof in Rome, investigates the transformative potential of large architectural complexes, such as stadiums, to serve as energy resources for local communities through the installation of photovoltaic systems on their roofs. The examination of the Olympic Stadium in Rome reveals that the PV plant, dynamically simulated using the System Advisor Model tool, has a peak power of 4432 kWp. The sizing performed highlighted how the system could function as a veritable energy station in an urban context. It is feasible to store part of this energy in electrochemical accumulators, such as electric vehicle batteries, with a total capacity of 2.8 MWh. The remaining portion of energy was correlated with the average energy needs for both residential and non-residential users, as well as for public lighting. The results demonstrate how this system could be a significant contributor to the energy needs of the community, fostering sustainability and resilience. The designed system can store part of the event energy demand (176 MWh/year) and export energy (4.4 GWh/year) to the utility grid.  
The integration of renewable energy solutions, particularly through the designed PV system, showcases its potential contribution to the broader community's energy needs. The results demonstrate its ability to supply the energy demand of 634 household utilities or meet the lighting demand of 15,008 lamps within the framework of a renewable energy community. This underscores the pivotal role of large structures, like stadiums, in fostering sustainability and resilience within urban environments.  
The findings presented here mark the initial steps in an ongoing research endeavor. Future developments will involve implementing the proposed energy system on the Olympic Stadium and evaluating real-world energy and economic data to compare against the hypothesized scenario. This iterative approach ensures a practical understanding of the system's performance and its actual impact on the local community, aligning with broader goals of sustainable urban development and renewable energy integration.  
In summary, this study not only sheds light on the energy potential of the Olympic Stadium but also serves as a model for similar urban structures, emphasizing their role as integral components of renewable energy communities and contributing significantly to the broader sustainability agenda.
