Prologue
A number of small low-lying island nation-states in the South Pacific are undergoing a slow but inevitable process of being inundated by rising oceans. Their lands are disappearing and their cultures will die. One state in particular, Kiribati (pop. 103,000), has made a vocal plea for survival on the world stage. At the 2009 United Nations Climate Change Conference in Copenhagen, the president of Kiribati, Anote Tong, made this appeal to the assembly:
Climate change is indeed the greatest moral challenge of our time. I fear that our children and grandchildren will look back and ask, ‘How is it that they knew what they knew, and yet did so little?’ We simply cannot afford the consequences of inaction. The people of my country are already feeling the impacts of climate change, which will only worsen with time. We, together with those of other low lying states, are the human face of climate change.

Kiribati’s per capita carbon-dioxide emissions are approximately one-twentieth of China’s, one twentieth of the European Union’s, and one-fiftieth of the United States. Despite the fact the Tong and others have framed the problem of climate change in moral terms, worldwide carbon-dioxide emissions increased by 5% in 2011. The Kiribati government has acknowledged the reality of this situation by beginning to prepare its citizens for life as climate change refugees. A number of vocational training programs have been instituted to provide I-Kiribati with specialized skills for work in countries such as Australia and New Zealand.

New Atlantis
The year is 2100 and what was once called the nation of Kiribati is gone, its chains of low-lying islands have been completely submerged by the Pacific Ocean. Many I-Kiribati and their descendants have dispersed to Australia where they work in the health care industry or to New Zealand where they work as maritime shipping specialists. In these host nations, the I-Kiribati have become diffused. As a result, their culture and language has nearly died.
But rather than letting their culture become a myth of the lost like
Atlantis, other I-Kiribati have refused to become refugees of climate
change and elected to remain in place, at least geographically. They
now live in a vertical city situated in the open ocean. The city is in
shallow water directly above what used to be South Tarawa, the
ex-capital of Kiribati on Tarawa Atoll. The city’s foundations are
anchored into the earth, which is now approximately 20 feet underwater.
It is an elaborate structure paid for through donations from the
Chinese government, which in 2050, (rather than enforcing carbon
reduction measures) chose to alleviate national guilt by donating
billions of Yuan to island nations that were disappearing under rising
oceans.

The ex-I-Kiribati living in the city of New Atlantis consider themselves exiles. They have been given an elaborate vertical structure that is largely self-sustaining and in some ways quite comfortable. But they have all lost their homes and culture, many have also lost their families. Politically, the city resides in a grey zone. The Kiribati state is no longer recognized by the United Nations, and New Atlantis is a city-state that operates outside normal international political and economic boundaries. As a result, the ex-I-Kiribati share their city with other voluntary exiles such as Eastern European digital pirates, American eco-terrorists, and escaped Chinese political prisoners.
Physically, the city is isolated, far from any significant landmass, cut-off from jet travel, and even distanced from trans-pacific shipping lanes. But digitally it is as networked as any metropolitan high-rise building. As such, it has become significant base of operations for politically and economically grey activities.

Building Description
Structure: Two sets of twisting vertical elements intertwine with each other. One set holds the floorplates, contains the residential spaces, and is skinned with translucent lexan. The other set, which works as the primary vertical building structure, contains the circulation cores and is constructed from lightweight fiber reinforced concrete. The horizontal arms of the city, which spread over the water, are floating aluminum and lexan structures. Floatation allows the arms to absorb energy of waves in the water and for the city to adapt to continually rising sea levels.
The structure is organized by two sets of 8 twisting tubular elements
which form both the vertical and horizontal components of the building.
These 16 (8+8) tubular elements are dupilacted and mirrored about a
central axis creating 32 (16+16) tubular elements in total. One set of
twisted tubes houses the inhabitable spaces, the other houses
circulation and service cores. The two sets are intertwined with each
other, and as they transform along the length of the building, a number
of different spatial organizations emerge.

Climate: The building does not incorporate a traditional climate control system, as this would over-tax the building’s energy generation capacity, and it is not necessary the warm South Pacific climate. Most of the structure’s interior spaces are only partially enclosed; wind and rain infiltration is accepted and even welcome.
Circulation: There are two vertical lifts that run curving routes up though the building. These are generally used only for service because their operation strains the building’s energy supply. Vertical circulation is primarily accomplished by walking up and down stairs. Commuting from the residential zone to the lower levels, especially when carrying food, is arduous, but a normal part of life in the city. Because of the effort it takes to circulate vertically, it is usually not done more than once a day. As a result, large-group gathering and meeting spaces are scattered vertically throughout the building.

Energy: The building generates its own energy with windbelt technology. The windbelt is a taut band held in place by a carbon-fiber frame. The windbelts are gathered into bundles that sprout from the upper reaches of the tower like hair. The building’s battery system stores electricity when winds are high, and this surplus is usually enough to power essential systems during periods of low winds. But the city survives by being frugal with its power. Energy priorities go first to water desalination and second to computing equipment.

Food: Many residents of the city are excellent fisherman. The city’s floating horizontal arms are used as boat docks and seafood processing areas. The horizontal arms also house saltwater greenhouses and desalination units.
The city supplements food, drink, and other essential and non-essential material supplies (black market, grey market, or otherwise) with periodic boat shipments form the mainland. Many of the city’s residents are quite wealthy, but collectively they elect to minimize physical contact with the outside world.
