This thesis forms the first phase of a broader project aimed at creating a sustainability assessment framework tailored to Italian university campuses, which differ structurally and institutionally from standalone buildings or urban districts. A systematic literature search across scientific databases produced 388 articles; after removing duplicates, 138 remained. Abstract screening identified their sustainability themes based on the SNTool structure, leading to a selection of 44 globally or European-focused studies for full-text review. From these, 258 distinct sustainability indicators and 55 assessment tools were extracted. A prototype campus assessment was then developed using the 20 most recurrent indicators. Eight stakeholder groups were defined, whose preferences were simulated by AI to rank the indicators.
