#### 4.6.1 Convenience Maps
Within the North-East Italy macro-area (regions of Trentino Alto Adige, Friuli Venezia Giulia, Veneto, Emilia Romagna), the same analysis has allowed one to verify an almost total convenience in activating energy improvement interventions for all the regions located in this cluster: in fact, for all the central areas of the provincial capitals located in Trentino Alto Adige, Veneto, and Emilia Romagna, a positive variation in terms of property prices between the ante-energy intervention and post-energy intervention has been recorded, whereas for one provincial capital of Friuli Venezia Giulia region (city of Gorizia), a scarce convenience has been detected. From the analysis performed for the semi-central and peripheral areas of the North-East Italy provincial capitals, a total convenience has been found for the Trentino-Alto Adige region. For the region of Friuli Venezia Giulia, a relevance convenience has been indicated for the semi-central area of all the cities considered, except for the provincial capital of Gorizia and for the peripheral area of all the provincial capitals aside from Udine and Gorizia. Furthermore, only for three provincial capitals of the Emilia Romagna region out of the nine, there is no convenience in implementing an energy retrofit intervention on buildings located in the semi-central area, and for three out of seven provincial capitals the semi-central areas of the cities located in the Veneto region a scarce convenience has been attested. Moreover, a lower convenience to invest has been found for the peripheral areas of the provincial capitals located in regions of Veneto (for four out of seven, an absence of convenience has been revealed) and Emilia Romagna (for six out of nine, no benefits have been identified). By analyzing the results obtained for the regions located in Central Italy (regions of Toscana, Umbria, Marche, and Lazio), an absolute convenience for all three urban areas considered has been found for the region of Toscana. For the provincial capitals of Umbria, monetary benefits deriving from the energy retrofit investments in central and semi-central areas have been observed, whereas in the peripheral area only for the city of Perugia, no convenient condition for the private investor has been recorded. For the Marche region in the peripheral urban area only for the city of Ancona and in the central and semi-central areas for the city of Ascoli Piceno, an absence of convenience to implement an energy improvement initiative has been pointed out. Finally, with regards to the Central Italy cluster, (i) a total convenience in the central areas of the Lazio region provincial capitals, (ii) significant market value differentials in the semi-central areas of the cities (only for two provincial capitals out of five there is no positive surplus) and (iii) a lower convenience in the peripheral areas of the same provincial capitals (for three cities out of five, monetary benefits in redevelopment investments have been verified) have been attested. Within the regions located in the Southern-Italy macro-area (Campania, Abruzzo, Molise, Basilicata, Puglia, and Calabria), for the central, semi-central, and peripheral areas in which each provincial capital analyzed is divided, the percentage of those for which a convenience to invest has been observed are reported below: for the central areas, 75% (3 for 4) of the provincial capitals for the Abruzzo region, 100% for Molise (2 for 2), 80% for Campania (4 for 5), 67% for Puglia (4 for 6), 50% for Basilicata (1 for 2), and 60% for Calabria (3 for 5); for the semi-central areas, 50% of the cities for the Abruzzo (2 for 4) region, 50% for Molise (1 for 2), 80% for Campania (4 for 5), 50% for Puglia (3 for 6), 50% (1 for 2) for Basilicata, and 40% (2 for 5) for Calabria region; and for the peripheral areas, 75% (3 for 4) of the provincial capitals for the Abruzzo region, 50% (1 for 2) for the Molise region, 80% (4 for 5) for the Campania region, 50% (3 for 6) for the Puglia region, 100% (2 for 2) for Basilicata region, and 0% (0 for 5) for Calabria.
