By 2050, the Greenest City May Not Be in the First World

By 2050, the Greenest City May Not Be in the First World | Ambiances, Architectures, Urbanités | Scoop.it
Cities might be burning three times more energy in 2050 than they did in 2005—unless they act now.

Currently, more than half of the world’s people live in cities. Given the trend of jobs returning to urban centers, it may not be surprising that by 2030 the world’s cities will be home to 60 percent of the world’s population. Cities are adapting to accommodate the growing population by becoming sustainable and green.

Yet assuming that the current rapid pace of population growth continues, cities will be burning three times more energy per capita in 2050 than they did in 2005 despite their “green” efforts. Even with increasing favor toward public transport in the first world’s largest cities, the cities with the greatest opportunity to reduce energy use are those in the still-developing second world, particularly in Asia, Africa, and the Middle East.

Inside Arcology, the City of the Future (Infographic)

Inside Arcology, the City of the Future (Infographic) | Ambiances, Architectures, Urbanités | Scoop.it

For over a century, writers and architects have imagined the cities of the future.

 In the late 1960s, architect Paolo Soleri envisioned “arcology” - a word that combines “architecture” and “ecology," with a goal of building structures to house large populations in self-contained environments with a self-sustaining economy and agriculture. “In the three-dimensional city, man defines a human ecology. In it he is a country dweller and metropolitan man in one. By it the inner and the outer are at ‘skin’ distance. He has made the city in his own image. Arcology: the city in the image of man.” (Paolo Soleri)

For over a century, writers and architects have imagined the cities of the future as giant structures that contain entire metropolises. To some, these buildings present the best means for cities to exist in harmony with nature, while others forsee grotesque monstrosities destructive to the human spirit. In the mid-20th century, engineer and futurist R. Buckminster Fuller imagined city-enclosing plastic domes and enormous housing projects resembling nuclear cooling towers. These ideas are impractical but they explore the limits of conventional architectural thinking.  Science fiction writers and artists often imagine future architecture that oppresses the human spirit. Megastructures such as the pyramid-like Tyrell Buildings of “Blade Runner” dominate a decrepit skyline. The decaying old city is simply covered with layers of newer, larger buildings in a process of “retrofitting.” Beginning in the late 1960s, architect Paolo Soleri envisioned a more humane approach. The word “arcology” is a combination of “architecture” and “ecology.” The goal is to build megastructures that would house a population of a million or more people, but in a self-contained environment with its own economy and agriculture. “In the three-dimensional city, man defines a human ecology. In it he is a country dweller and metropolitan man in one. By it the inner and the outer are at ‘skin’ distance. He has made the city in his own image. Arcology: the city in the image of man.” (Paolo Soleri) In 1996, a group of 75 Japanese corporations commissioned Soleri to design the one-kilometer-tall Hyper Bulding, a vertical city for 100,000 people. Existing in harmony with nature, the Hyper Building was designed to recycle waste, produce food in greenhouses, and use the sun’s light and heat for power and climate control.  The structure was designed for passive heating and cooling without the need for machinery. An economic recession put the brakes on the project and it was never built. Soleri’s arcology concept is being put to the test in the Arcosanti experimental community being built in Arizona. Construction began in 1970. When complete the town will house 5,000 people. Buildings are composed of locally produced concrete and are designed to capture sunlight and heat. To be built in the desert near Abu Dhabi, Masdar is a 2.3-square-mile (6 sq km) planned city of 40,000 residents. Buildings are designed to reduce reliance on artificial lighting and air conditioning, and the city will run entirely on solar power and renewable energy. Begun in 2006, the project is planned for completion around 2020-2025.

Amazing and beautiful analysis!! Believe it or not, the science fiction also has something to teach us about the city of tomorrow.
