The façade that closes the south face of the tower seems from the outside to be a simple stick curtain wall that would be of little interest if it were not for the fact that it is photovoltaic. We have dedicated a section to it because of the uniqueness of the space it contains, and the abstraction in the design that this allows. This curtain wall is the enclosure of the elevator core and therefore is devoid of many of the requirements of a façade.
