Polar Umbrella, First Place eVolo Skyscraper Competition 2013.
FROM THE ENTRANT:
During the last decades of global warming, the polar ice caps have experienced a severe rise in temperature causing the northern and southern ice shelves to become thin, fractured, and melt into the ocean. Rebuilding the arctic layers is the primary objective of this proposal which cools down the Earth’s surface by reducing heat gain in vulnerable arctic regions.
The Polar Umbrella’s buoyant super-structure becomes a statement for the prevention of future depletion of our protective arctic region. Through its desalinization and power facilities, this arctic skyscraper becomes a floating metropolis equipped with NOAA (National Oceanic and Atmospheric Administration) research laboratories, renewable power stations, dormitory-style housing units, eco-tourist attractions, and ecological habitats for wildlife. A series of these structures would be strategically located in the most affected areas.
Salt water is used to produce a renewable source of energy through an osmotic (salinity gradient power) power facility housed within the building’s core. In addition, the structure’s immense canopy allows for the reduction of heat gain on the arctic surface while harvesting solar energy. The umbrella’s thermal skin boasts a series of modules that are composed of a polyethylene piping system that pumps brackish water. Finally, the Polar Umbrella also regenerates the ice caps using harvest chambers that freeze the ocean water.
