21Specific Features and RemarksIIS “Marconi‐Pieralisi” High School, Municipality of Jesi (AN), Italy

f kSpecific Remarks

The school is composed by 2 different building blocks with different history and features.The “Pieralisi” block was almost completely renovated between 2007‐2010. Structural Compliance has to be assessed in the 80’s building.They were analyzed together in this project because the energy meters were shared, so the

il bl i d f d h f h b ildiavailable consumption data referred to the sum of the two buildings.
