20Specific Features and RemarksITIS “A. Merloni” High School, Municipality of Fabriano (AN), Italy

f kSpecific Remarks

The school has a lot of “evening courses”, thus it is opened till night.

There are a lot of glazed facades. Windows Replacement was started in 2015 with 4 facades. It needs to be completed.

Seismic Compliance needs to be assessed. After the assessment works could be needed.
