Everything from single-family residences to  giant 1.2-million-square-foot complexes complete with giant skyscrapers is  getting the green treatment, and the innovation that’s going into these plans is  more complex than ever. Some of these structures will debut as early as the fall  of 2008 while others present a view of what 100 years from now may hold, but all  represent amazing leaps in green technology that push the boundaries of what  we’ve ever thought possible.
 

 

 
Architect David Fisher has proposed a plan for rotating towers that produce  all of their own energy through wind power. The ‘Rotating Tower’ would be  built by stacking ‘platters’ on a central concrete core with wind turbines  located between each of them. Each floor will rotate 360 degrees about once  every 90 minutes; as the floors will rotate independently, they will create a  constantly changing silhouette in the sky. Inside the concrete core will be  elevators, emergency stairs and lobbies. The Rotating Tower will be built in  Dubai in the next six months.
 

 

 
As water becomes an even hotter commodity in the future, engineers are  looking for ways to ensure a continued supply of fresh water to meet the needs  of the world’s growing population. Charles Patton is tackling this problem with  his ‘Seawater Greenhouse’, a carbon-neutral desalination method which is being  incorporated into the design of the Teatro  del Agua. This ‘Theater of Water’ will be a performing arts center in  Spain’s Canary Islands. It works by coupling “a series of evaporators and  condensers such that the airborne moisture from the evaporators is then  collected from the condensers, which are cooled by deep seawater.” The center  will operate almost entirely on renewable energy.
 

 
The ‘Dice House’ is a zero  carbon home, which can either stand alone or function as attached multiple  dwellings. Designed by Sybarite, a British architecture firm, the Dice House is  a 9 x 9 meter cube that sits on an octagonal plinth. Three levels inside the  cube have large, plentiful windows to maximize views. A large thermoplastic  ‘umbrella’ on the garden roof of the house shades and insulates the house and  collects solar energy.
 

 

 
The new Las Vegas ‘CityCenter’ is  the largest privately financed development in North America. This $8 billion  project is a joint venture between MGM Mirage and Dubai World. Designing the  CityCenter will be renowned green architects including Pelli Clarke Pelli,  Foster + Partners and Rafael Vinoly. MGM Mirage has trained over 10,000  construction tradesmen on green building practices to be put into place in the  structures. CityCenter, which will house hotels, casinos, restaurants, retail  space, entertainment space and a $40M public fine arts center, is touted by its  developers as a model of sustainability. Recycling construction waste, using  environmentally friendly materials, emphasizing natural light and incorporating  an onsite co-generation power plant are just a few of the sustainability  initiatives that will be put into place.
 

 
Architect Sheila Kennedy has designed the Soft  House, a structure that harvests energy through solar-energy-collecting  textiles hung in the home like curtains. These thin-film photovoltaic textiles  can create close to 16,000 watt-hours of electricity, providing about half of  the home’s power. Though the high cost of this solar technology makes the Soft  House unlikely to become reality any time soon, Kennedy hopes that the design  will show others that renewable energy technologies can be incorporated into  structures in creative and unexpected ways.
 

 
The world’s first passive house museum  is set to be built in Ulricehamn, Sweden, functioning as a visitor’s center. The  building’s heat will be supplied entirely by the body heat of visitors and the  equipment located inside. Solar cells on the roof will provide part of the  energy used to run electrical equipment and heat water. The circular design of  the structure will allow efficient circulation of air to enhance the passive  heating and cooling of the building.
 

 
The Chicago Spire is an  ambitious project currently under construction in the Windy City. At 2,000 feet,  the spire will be North America’s tallest free-standing structure and the  tallest all-residential building in the world. Designed by Spanish architect  Santiago Calatrava and managed by the Shelbourne Development Group, the Chicago  Spire was designed to mimic the natural form of a nautilus shell. The structure  is anticipated to have a LEED gold rating; it will be outfitted with rainwater  harvesting systems, geothermal cooling and high performance glass designed to  protect migratory birds. The Chicago Spire is set to be completed in 2011.
 

 

 
Frasers  Broadway, a commercial, residential and retail complex, will be Australia’s  most sustainable building. The designers, including Pritzker Prize winners  Foster & Partners and Ateliers Jean Nouvel, will incorporate such  eco-friendly features as a gas-powered co-generation electricity plant, green  rooftops, a wastewater recycling plant, smart metering and solar power into the  design in an attempt to achieve carbon neutrality. The 250,000 square meter  development will be located in the old Kent Brewery in Sydney.
  

 

 
Pelli Clark Pelli architects recently got approval for their design for a new  green Transbay  Transit Center in San Francisco. The transit center will consist of a glass  tower and a five-and-a-half acre public park, and will be packed with  sustainable features like green roofs, passive solar shading, wind turbines, a  rain and graywater recycling system and geothermal heating and cooling. The aim  of the building is to centralize the region’s transportation system while also  providing a community space. The center will be completed by 2014.
 

 
China’s population is exploding while its industrial ventures are producing  more pollution than ever – a combination that makes it difficult to be  eco-friendly. A new sustainable housing project called Habitat  2020 aims to be one of the leaders in bringing environmental initiatives to  this growing country. The Habitat 2020 building will feature an ‘active skin’: a  membrane between the exterior and interior walls that will absorb air, water and  light from outside and dispatch it inside as clean filtered water, natural air  conditioning and electricity. The same funnels on the membrane that pull these  resources in will also emit clean, CO2-free air from inside the building. This  urban megalopolis is set to be complete in 2020.
 

 
Another project that aims to act as a ‘living’ structure is the California  Academy of Sciences museum set to open in San Francisco this fall. The  museum will have a 2.5 acre, undulating green roof that will integrate it into  the surrounding Golden Gate Park. The 400,000-square-foot, $484 million  structure will likely be the first public building to achieve a platinum LEED  rating. Designer Renzo Piano has incorporated a planetarium, a rainforest with  free-flying birds, a coral reef home to 4,000 fish in a saltwater aquarium and a  natural history museum into the building.
 

 
Maul Dwellings designed the ‘Landscape  House’, which won the AIA’s 2006 Committee on Design competition to design  “a house for an ecologist”. The house not only features a double roof for  enhanced air circulation, louvered shutters to harvest energy, a ‘Water Pod’ to  house efficient plumbing systems and a solar dehumidifier unit to capture  moisture from the air for drinking water, it also is designed for deconstruction  and reuse. Though this innovative structure wasn’t originally intended for  widespread residential use, its intelligent eco-friendly features make it a  great source of inspiration for future green homes.
 

 
Kuwait will soon have its first LEED skyscraper. The Sabah Al Ahmed  International Finance Center will be a 1.2 million square foot, 40-story  tower that includes four stacked courtyard atriums ranging from 8 to 13 stories  each. The tower will generate some of its own energy from a photovoltaic system  as well as the wind turbines that will crown the roof. Inside will be office  space and a 4-star business class hotel. The International Finance Center (ICF)  has been precertified at the gold level under the LEED rating system.
 

 

 
London-based Foster + Partners, who are also working on the aforementioned  Frasers Broadway complex, have another green complex in store. This one will be  located in Singapore  City, measuring 150,000 square meters and set for multi-use functioning. The  complex’s exterior will be covered with solar cells, and direct sunlight will  also be harvested by tall ribbon-like canopies rising into the skyline. The  slanted design of the facades will allow wind to flow into the building for a  natural cooling effect, and vertical green spaces will provide ambient  temperature moderation. The building will also be equipped with a rainwater  harvesting system, geothermal heating, chilled beams and an ice storage system  for cooling.
 

 

 
The furthest-reaching green wonder of the future is IwamotoScott  Architect’s vision of San Francisco in 2108. This stunning winner of the  History Channel’s City of the Future competition shows what a totally  eco-conscious San Francisco could look like 100 years from now, complete with  algae-harvesting towers, geothermal energy ‘mushrooms’ and fog catchers to  distill fresh water from the city’s foggy atmosphere. Designed to make the most  of the area’s microclimate and geology, Hydro-Net is a network of both  above-ground and underground systems that takes the need for alternative energy  sources in mind with a connected network of water, power collection and  distribution systems. Carbon nanotube walls would collect and disperse hydrogen  produced by algae, which would be used to hover-cars in underground tunnels.
