The preservation of these works is not only artistic, but also cultural and social. The technical monitoring of such works, aimed at avoiding the degradation and the occurrence of critical situations that undermine the preservation and/or the materialization of irreparable damage, has been particularly difficult to date: the quantity of works present in the territory and their distribution, with relative budget of expenditure for the preservation and safeguard often reduced, have been an obstacle difficult to overcome. The main purpose of the data collected by the monitoring system would be to allow, on the one hand, the assessment of the risk for the work in question and, on the other, the management of the risk itself. 

Climatic changes and environmental pollution have induced an additional element of uncertainty: humidity, temperature and air composition, combined with the increase of other elements such as sulfur oxide (SOx) and nitrogen oxides (NOx)have led to an increase in the acidity of precipitation, as well as a greater aggressiveness of the condensation of moisture, resulting in an attack on works of art particularly sensitive to such compositions. The continuous and intelligent monitoring of the state of the works would therefore allow a significant reduction in these costs, in addition to the concrete possibility of carrying out preventive interventions, which would significantly reduce the risk of irrecoverable damage.
