Maximizing Energy Performance of University Campus Buildings through BIM Software and Multicriteria Optimization Methods

University buildings have high energy requirements due to their size, numerous users, and activities, which considerably contribute environmental contamination. Implementing energy-saving solutions in these structures has a favorable influence on the economics conservation of resources. A higher education building’s behavior can be simulated using software identify optimal strategies that result savings. In this research, Autodesk Revit, Insight, Green Building Studio are among programs utilized examine efficiency university building four European cities. Following development several scenarios for building, offered evaluated based annual consumption, costs, CO2 emissions. Finally, multicriteria analysis techniques such as AHP PROMETHEE applied choose best scenario each instance. The study’s findings indicate ASHRAE Terminal Package Heat Pump performed well all cities examined, reducing yearly usage by 43.75% Wien costs 47.31% Mallorca. comparison, utilizing high-efficiency VAV system with gas boiler chiller came last situations, resulting decrease 12.67% Mallorca’s reduction 17.57% Palermo’s expenses.
