The cylindrical-shaped auditorium is linked to the main complex via a glass-adorned tensile structure that outlines the large covered pedestrian square. Here the lighting had to allow the most accurate color rendition possible to enhance the pleasure of meeting people and appreciating the elegance of both the venue and of the people enjoying themselves. Furthermore, the need to signal the events taking place in the hall could not be ignored and was achieved by varying the intensity of the lighting. Halogen bulbs with dichroic reflectors were used to light up the foyer, the cafeteria, the distribution zones and public areas. The radial arrangement of fixtures, each equipped with an internal display screen made from etched glass, guaranteed an even distribution of luminance levels - thanks to the overlapping of light beams on both the horizontal and vertical surfaces - without producing glare or strong shadows. The hall was conceived as a large musical instrument: the curved terracotta panels and suspended shapes work together to reflect the sound towards the audience. For indirect lighting, theatre-type projector lamps with powerful halogen bulbs (100/200W) were attached to tall metal posts arranged in a circle. This choice allowed the necessary devices to be joined together for both the general lighting of the hall and the scenic lighting required onstage during shows and concerts, creating a coherent image with powerful and spectacular effects.
