250,000SF - architecture as infrastructure II
42-story CO2-scrubbing, eco-friendly residential 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 work better when wind is present, the tower opens up in the middle to accelerate air speed as it travels through the gap.
The building is comprised of two cores each serving four to six units per floor. The two wings of the tower connect at the bottom lobby and at the top, where the last five stories are designed for multi-level units and amenities. The bottom six stories house the parking structure, which continues underground where the envisioned grid for distributing the liquid carbon dioxide is also located.
The entire glazing system of the building is covered with a thin-film solar cell (TFSC) by Nanosolar. This technology allows for a thin-film photovoltaic cell (TFPV), to be deposited in thin layers on a substrate. This system alone makes each unit self-sufficient in terms of the energy needs. Further, the slender profile of the tower and its location on the site also contribute to the energy efficiency of the building, which is oriented to take advantage of prevailing winds and day lighting.
