The document provides a detailed analysis of energy consumption in the banking sector, outlining methodologies for creating benchmarks for energy efficiency. It includes an introduction to the European and Italian regulatory context regarding energy sustainability. The population of analyzed data is described, divided into branches, buildings without data processing centers (CED), and buildings with CED, highlighting the differences in consumption and systems. Various KPIs are presented to evaluate the energy efficiency of banking structures, and the conclusions suggest that the results can serve as a reference for further energy improvement interventions in buildings.
