The investigation

This chapter focuses on how to approach HIM investigations starting from the study of AIM. Investigations are divided in two main groups: (i) Indirect Investigations (archive, bibliography, iconography, modelling tools); (ii) Direct investigations, which includes all the survey on the monument (metric survey, mapping of technical systems, project of AIM monitoring). The data collected through each kind of investigation must be interpreted to sketch a frame through which to state how HIM has changed over time and how it may have affected the historic building and the arte-facts inside it (e.g. furniture, paintings, frescos). All these data (metric, environmental, material) will be collected and synthesized in a following phase through 3D and environmental modelling. This kind of method is a rigorous process which ensures that interventions on historic buildings will be in line with its cultural value, including intangible one.
