“…The majority of the methods (60%, i.e., n = 29) (e.g., [44,47]) were applied to single (as a whole) buildings while the rest (40%, i.e., n = 19) to interventions at district level (e.g., [34,49]) (see Figure 6a). Regarding the occupancy of the building, about 33% focus on residential buildings (n = 16, e.g., [48,50]), 17% on religious buildings (n = 8, e.g., [45,51]), 10% on educational buildings (n = 5, e.g., [24,25]), 8% on museums (n = 4, e.g., [31,32,46]) etc. (see Figure 6b).…”
