Miami Tower

The tower's architecture integrates a new technology developed by Colombia University Professor Klaus Lackner and referred to as an "artificial tree". A series of resin columns is organized on all available areas of the tower that are exposed to the prevailing winds. As the wind blows through these resin columns, carbon is trapped in a chamber between the double slab at each level of the tower; the carbon is subsequently compressed and stored as liquid carbon dioxide in the cellar levels. The gap between the two slabs between the two floors also allows for cross ventilation that cools the floor slab of one unit and the ceiling slab of the one below. As the CO2-scrubbing columns better work when wind is present, the tower opens up in the middle to accelerate air speed as it travels through the gap.
