There is a 1-meter space between the facade and the windows which allows hot air to rise and cool air to come in from below. The facade is 40 cm thick and made of an extremely fluid concrete. It has 1000 circular openings of various sizes. The building is held up by the core and exoskeleton so the space inside is largely column free.
