The facade combines architectural lighting and dynamic lighting. The building responds as though it were alive at night. Plaza de España is a place of architecture, culture, cafes, restaurants, bars; and people from all over the world. Thus, the design is inspired by the idea of the steadily changing movement of people in the square, like the water in a river or clouds crossing the sky. Invisible in the daytime, the illumination mimics the flow of urban life at night.
