Thefocused and increased wind speeds maximize the amount of air pushed across thetitanium dioxide panels, provide cross
ventilationforevery unit in the towers, and power a series of vertical wind turbines.Positive pressure is created on the southern face of the towers and theresulting negative pressure on the northern façades creates optimal conditionsfor cross-ventilation. Careful attention has also been placed to prevent thebackflow air from one unit into another. The nano coating has the added benefitof neutralizing bacteriological contamination.
Theskin design is inspired by the pocketed and cellular texture of the TiO2molecule. A series of organic cells cover the building and are tapered tonaturally collect the water, a byproduct of the skin’s chemical reaction, andto collect and slowly release rainwater.
Theskinpulls off of the building on the south façades to provide natural shading andpushes into the inner skin of the north façade to maximize daylight.
Public gathering places
A series of gardens are located atregular intervals all the way up the tower. They become public gathering spacesas well as marsh lands to collect the water from the chemical reactions of theskin and to filter and process gray water from the towers. The plants also turnthe carbon dioxide, created in the chemical reaction of the skin, back intooxygen.
It isparamount to have the plants help maintain the base-level carbon neutrality. Alarge pool around the base of the tower is the final collection point of thefiltered water, which goes to support a large amount of animal and plant life.Water is also pumped back up the towers from the pool to service toilets.Furthermore, the pool at the base acts as a heat sink for the release of theheat generated from a back-up air-conditioning system. Here, the heat isreleased slowly, thus helps reduce the heat island effect
The research projects are used as a meansto advance sustainable designs within the firm and theresults are often incorporated directly into current projects. Beyond theobvious environmental benefits, lO has realized the commercial value ofadvanced green technology. The sustainable technologies are catching onespecially well in large-scale residential projects because they bring a bettervalue to the individual units and gain tax credit from local governments.
