This paper presents an energy analysis of the school buildings of a province in central Italy. The analysis is aimed at calculating the main thermal and electric energy consumption indexes to determine the status of energy consumption and the possible intervention to save energy in the school sector. Two applications of energy auditing to school buildings are also presented. It is also shown that if the optimal energy consumption indexes could be valid for all the school buildings, thermal energy savings could reach 38% and electric energy consumptions could be reduced by over 46%.
