This document discusses building assessment systems and sustainability in Europe. It describes the CESBA tool and Protocollo Itaca system used in Italy to evaluate buildings. CESBA aims to standardize building assessments across Europe while allowing for regional differences. Protocollo Itaca evaluates buildings on issues like energy use, emissions, and indoor quality. Italian regions have used these types of assessments in policies, building codes, and green procurement to incentivize more sustainable buildings.

1. This project is implemented through the CENTRAL EUROPE Programme co-financed by the ERDF.

If well designed, it is possible to reduce the cost of green buildings.
Green Buildings are more attractive on the market:
Reduced operation cost
Higher productivity
Value stability
