Retrofit of existing buildings gives rise to the problem of defining what must be preserved and what must be transformed. This involves a complex evaluation of several factors and a particular care during the initial phase of study. That's why diagnostics can take on extremely different roles and meanings. It involves several interactions between kinds of knowledge having different nature which originate many difficulties. The word "diagnostics" brings to mind a "sick" organism and emphasizes the need to find out the causes of the "malaise". This is a preliminary condition before assuming a prognosis or a forecast of the future course, as well as an hypothesis of therapy or the ways and means intended to fight it. The following work provides some contributions to the development of diagnostics, in particular the non-destructive one, in the building field. In this connection, it presents a particularly meaningful case history about the satisfactory organization of a phase of preliminary diagnosis, instrumental diagnosis and interpretation of results. Finally, the work will deal with the primary initial requirements and needs to be fulfilled in order to further develop and diffuse the use of diagnostics.
