Dynamic simulation is increasingly vital in the energy transition, offering advantages over steady-state modeling. However, its widespread adoption faces hurdles, notably in acquiring real input data and interpreting results effectively, limiting its legal effectiveness in Italy and elsewhere. Energy audits, empowered by advanced modeling, should become standard practice, rather than reserved for exceptional buildings. Hourly dynamic simulation, crucial for capturing energy usage and occupant comfort variations, requires adaptable building automation systems utilizing sensor networks. This study compares two dynamic simulations conducted on an identical classroom at the University of Basilicata, Italy, using real input data collected via a sensor network, highlighting the importance of adaptable building automation systems accessible to all stakeholders. This inclusive approach enables tailored design solutions, aligning with EU ecological transition goals and positioning dynamic modeling as a key driver in sustainable building practices.
