The aim of this proposal is to integrate urban life into an
ecological self-sufficient skyscraper. Located in Madrid, on the bank of
the Manzanares River, the design by Addler Elizalde Lozano
is a faceted urban sculpture for multiple programs, including
residences, hotel, and commercial, and recreational areas. The façade is
designed through folding solid planes that protect the interior from
the hot climate. Small opening in conjunction with an open central core
provide natural light and ventilation to every space. At the ground
plane, a urban plaza interacts with the building while creating a urban
path across the entire skyscraper. Apart from the passive energy
systems, the building is equipped with solar panels and wind turbines
that will power up to 40% of the structure.
