The analysis was conducted in order to study urban daylight in public spaces in terms of the overshadowing effect. The first public space analyzed is the existing square of the town hall (Fig. 06). The results demonstrate that in the current design scenario the urban daylight availability of the square is 7.5% less than the initial scenario. The second public space analyzed is the courtyard created between buildings A and B (Fig. 03). The increment in the daylight availability in the optimized design scenario is equal to 56.5% with respect to the current design scenario.
