The miracles of Dubai

Yeah, while we're sitting here talking, some people invest big time in technology and science. I can't but respect those countries that host crazy and amazing achievements of terrestrial engineering. You think it's too much wasted money? Well, I don't see the difference whether we spend big money to go to Mars or to build extremely luxurious and complicated hotel. Yeah, I also prefer to colonise Mars, but well, that's hard and requires continuous flow of money that we cannot secure. So, let's appreciate the miracles of Dubai and imagine what we'd do with the same amount of money.
And if you read the second article, you'll see it's not only beautiful, it looks like it will be also functional!

Dubai Will Build & Export Rotating Pre-Fabricated Units For Rotating Towers

Dubai Rotating Tower

Dubai will be home to and international hub for an innovative skyscraper, which will keep changing its shape and generate surplus energy from the wind as well as the sun.

The ’tower in motion’ is a revolutionary project based on “Dynamic Architecture”, a new concept introduced by Florentine architect David Fisher. The project has generated considerable interest all over the world even before its launch, as a trend-setting architecture.

Details of the unique building design, production of clean energy and the innovative technology that distinguishes this milestone in contemporary architecture were presented to an audience that included local and international media at the Burj Al Arab yesterday.

The new building will be the first skyscraper “produced” with industrial systems process: in fact, 90% of the building will be constructed as modules in an industrial plant and, then, assembled on the central core, the only part that will be built “on-site” using traditional techniques.

Dubai will be home to this revolutionary architecture in all sense as the pre-fabricated units for the tower will be produced in a facility set up in Jebel Ali. These units will then be shipped to 11 other major cities including Moscow, Milan, New York and Tokyo where similar towers will come up following Dubai.

Each floor of the tower will consist of 12 modules that will arrive at the job site completely finished and with electrical, plumbing as well as air-conditioning systems ready for use. The modules will then be mechanically assembled at the rate of one floor every seven days.

This provides a series of important advantages: first of all, the application of industrial quality control techniques to the finished product, the possibility of customizing individual apartments, reduced production times and costs and, last but not least, reducing the risks of accidents and injuries on the job site. In fact, production and installation will require only 90 technicians and workers on the site, as against over 2,000 for a comparable traditional building.

Dubai Rotating Tower

Another innovation that distinguishes the tower of endless shapes is its dynamic use of space, which not only adapts to its surroundings but also to the tenant’s needs and, why not, the tenant’s caprices. Thanks to a mechanism that allows each floor to rotate autonomously by virtue of voice activated technology, it will be possible to select the view from the window at any moment, deciding how to use the daylight or to let it rotate slowly as viewers enjoy the surroundings. The external shape and profile of the tower can also change constantly, letting a new way to see architecture come to life: non motionless anymore, but dynamic.

But that's not all. The tower is also a “green” building that generates electricity for itself and five other equivalent buildings. The secret is 48 wind turbines mounted horizontally between one floor and the next, and the photovoltaic cells located on the roofs of the individual apartments. Never before has a building been designed to produce so much more energy than it consumes.

When completed, the skyscraper will have 68 floors and will be 313 meters (1,027 feet) high. Built in association with local entrepreneurs, the tower will comprise a 6-star hotel, offices and apartments of various sizes besides five villas on the top floor. Each of the villas will have designated parking on the same floor with vehicles brought up and down in special elevators. The roof of the “Penthouse” villa will also have a swimming pool, a garden and an Arabian majlis.

For a quick return home, the tower will have a retractable heliport, a platform that will extend from the shell of the building at the 64th floor at the moment of landing, hus maintaining the ergonomics of the tower.

Since such features calls for a high level of integration between concept, design, planning, manufacturing of components and construction, many of the world’s leading companies and professionals have been contracted for this project.

The project has already aroused intense interest among both institutional and private investors. The first apartments could be delivered to buyers in a full ten months earlier than traditional delivery times.

Sales for the skyscraper, the construction of which will involve a total investment of $350 million, will be handled by Gowealthy, leading real estate company in Dubai.source

Skyscraper Creates All Its Own Energy

This skyscraper, to be built in Dubai, is called the Burj al-Taqa (’Energy Tower’), and it will produce 100% of its own power. The tower will have a huge (197 foot diameter) wind turbine on its roof, and arrays of solar cells that will total 161,459 square feet in size. Additional energy is provided by an island of solar panels, which drifts in the sea within viewing distance of the tower.

Burj al-Taqa’s cylindrical shape is designed to expose as little surface area to the sun as possible. A protective solar shield reaches from the ground to the roof, covering 60 degrees of the giant circular building. It protects the side most affected from the sun’s glaring rays, making sure that none of the rooms are exposed to direct sunlight. The diffuse light on the other sides of the building is tempered by a mineral coating on the windows.

The tower’s façade is to be built from a new generation of vacuum glazing that will only come on the market in 2008. The new top-quality windows are meant to largely shield the interior of the tower from outside heat — indispensable in a region where outside temperatures can reach 50 degrees Celsius (122 degrees Fahrenheit) in the summer. This is made possible by a new breakthrough in the quality of the materials used: the new vacuum glazing windows transmit as much as two thirds less heat compared to today’s products.

The architects chose an ancient Persian architectural feature as their model. Hundreds of years ago, wealthy merchants erected wind towers on the roofs of their houses, an idea which was eventually exported to the Arab world. The buildings, which have now become tourist attractions, have a natural air conditioning system. Lateral openings in the towers suck in cool air like a chimney. The heavier cool air sinks down and displaces the lighter hot air, creating a comfortable temperature inside the living space despite the scorching sun.

Gerbers’s design is designed to function in a similar way: The negative pressure created by winds breaking along the tower will suck the spent air from the rooms out of the building via air slits in the façade. The plan is for fresh air to be pumped into the interior of the building by means of a duct system at the same time.

Seawater will be used to pre-cool the air. Three large cooling units in the giant building’s cellar will eventually lower the temperature to a comfortable 18 degrees Celsius (64.4 degrees Fahrenheit). Transparent ducts will channel the fresh air into spacious atriums and from there into the corridors and offices. The building’s designers want to use steel ropes to suspend hanging gardens inside the air ducts, transforming a feature which is often regarded as an architectural blemish and hidden behind sheet metal in other buildings.

At the same time, the underground cooling center also cools the water in the pipelines running through the underside of each floor’s ceiling. The system of tubes is designed to be a modern air-conditioning system which cools gently without unpleasant air currents.

The Burj al-Taqa seems like the most recent example of a trend that has been observable for some time. In large cities such as Chicago, New York or Paris, environmentally friendly skyscrapers are being built that win ecological awards and apparently herald a new green wave in the construction of tall buildings.
