This auditorium was design taking the light into consideration. There are two types of light approach: the main entrance and the auditorium. In the main entrance the chosen type of light creates some kind of intimate space, remembering the clouds in the sky. Regarding to the auditorium, the light is the most important part of this project and helps to create different approaches considering the different spaces. Therefore the different type of light used helps also to create some kind of dynamic ambience. The lateral panels used in this auditorium produce organic light directions, and were design contradicting the inclination of the auditorium, pointing up, and consequently creating a sense of horizontality, for people who sit in the auditorium, besides not being horizontal. The panels work also differently, according to the spaces people use, due to the mix of lights, and also as an acoustic barrier. For this auditorium were chosen economic lamps taking in consideration the economic and the sustainable part of this project.
