Buildings located in historical centres are characterized by different historical, cultural, natural, morphological, and aesthetic value levels. In function of the different valuable elements, the IHC USRA buildings have been classified in the following four categories: i) building with historic-architectural valuable elements; ii) building with landscape interest; iii) building with specific heritage protection provisions (the so-called building of cultural interest). Conversely, the IHC USRC buildings have been classified only in two of them: the i) and iii) categories. Buildings not included in previous categories are defined “ordinary”. Note that OHC dataset is characterized by all buildings identified as ordinary. The AMU can be made by all buildings belonging to the same categories or to different categories. Therefore 5 AMU category have been defined (i.e. AMU made of i) ordinary buildings; ii) buildings with historic-architectural valuable elements; iii) building with landscape interest; iv) building of cultural interest allocated or v) building belonging to different categories) Distribution of the AMU l IHC L’Aquila and IHC Other is illustrated in Fig. 5 as a function of the AMU categories. It is noted that the IHC Other sample have only 13 AMU of cultural interest, i.e. 1.5% of the sample. While 44 AMU of cultural interest were IHC L’Aquila .

4. Repair and strengthening costs The analysis of the repair and global strengthening intervention (NBS> 60%) cost of buildings OHC and of AMU IHC with at least one building with E usability rating are presented herein. Thus, the database analyzed is related to 313 funding requests for buildings OHC, and 459 and 630 funding requests for AMU IHC and approved by USRA and USRC, respectively.
