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.
