‘Energy Tower’ Combines the Old with the New

Wednesday, January 7th, 2009

When innovative buildings pop up in the news, no one is ever surprised to hear that the next architectural wonder will be built in the UAE. Dubai, Bahrain, and Abu Dhabi all seem to be competing in the green building department.

The eventual goal is for buildings to generate much of their own energy. Burj-al-Taqa (translated to mean energy tower), which will hopefully break ground in Dubai soon, follows this principle and will supposedly be completely self-sufficient.

Plans for its creation began in 2007 when the German architect Eckhard Gerber, dreamt up the design. Virtual images of the building popped up in hundreds of articles and we all wondered if this candle-shaped building would revolutionize the green building industry.

The proposed Burj-al-Taqa zero-energy skyscraper.

A couple of interesting differences between this burj and all the rest, is its cyclindrical shape and the building materials used-both meant to help dissipate the heat. The tubular design is meant to minimize the surface area exposed to the sun while the special vacuum glazing used on the glass covering the entire structure will also help keep the heat out. This type of glass was only recently made available.

Burj-al-Taqa’s architects are also learning from history: Ancient Arabian houses used energy efficient technologies at a time when there were no other alternatives. (It is ironic how many buildings are reverting back to older technologies these days.) These old homes used a natural air conditioning system that sucked cold air into the living space via lateral vents which in turn forced the hot air out into the 120 degree summer heat.

The Spiegel describes how Burj al-Taqa hopes to use a similar process with their in-depth article: “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.”

It doesn’t stop there. Seawater running through the cellar and under each floor will cool the air, while a large wind turbine on the roof of the 322 meter building will help generate enough electricity to power the skyscraper. Massive photovoltaic facilities will help charge the rest of the power grid.

After construction, burj-al-Taqa will be the 22nd tallest building in the world, but if all goes well, it will tower above the rest when it comes to energy efficiency.

Editor’s Note: For more on buildings like the burj-al-Taqa, a very interesting website we have uncovered is the skyscraper category of “Jetson Green,” dedicated reporting on innovative green building design.

Outdoor Air Conditioning

Friday, December 19th, 2008

Sitting on a beach is the last thing most of us think about in the cold month of December, but it is an appealing escape. Beaches are the most popular destination spot and who could blame the millions of tourists whose tension is washed away by warm waves, exotic drinks and sunny skies. Nothing is ever perfect, though. The ocean may be too cold, and the sand is often scalding hot. It is just the nature of the beast and humans have to accept the fact that we cannot control everything. Yet, designers in Dubai may disagree.

The Palazzo Versace Hotel, breaking ground on Dubai’s coastline, is planning on creating its very own climate. The hotel’s sand will never burn sensitive soles thanks to a network of heat absorbing pipes under the beach and 820sq foot refrigerated pool will always refresh guests trying to escape the rising temperature. Not only that, but whenever temperatures become uncomfortably hot, fans may be placed around the hotel’s beach to force a cool breeze towards lounging guests.

Making outdoors indoors…

In addition to the one-of-a-kind beach, the 10-story hotel will incorporate indoor pools in some of the 213 rooms. For a more detailed list of the hotel’s guest features click HERE.

It comes as no surprise that environmentalists are not happy with the situation. It is also a slap in the face to countries facing the current economic crisis. A climate controlled beach seems like a waste of money, and the energy required to control an outside environment is immense. Not only that, but it is not even necessary: certain variables may be unappealing but they add to the charm of visiting a natural area.

Soheil Abedian, founder and president of Palazzo Versace, argues that luxuries like this can also be sustainable. Rather than forcing cool air onto the sand which requires more energy, for example, the heat will get sucked out. Unfortunately, the exact plans for the project are still unknown.

Dubai is already home of the world’s top resorts and countless luxury hotels, the most famous of which is Burj al’Arab-the first hotel ever to boast a 5 star rating. Abedian is simply following UAE tradition and attempting to compete with countless other hotels that have offer such amenities as private butlers in gold plated rooms that can cost up to $40,000 a night. He hopes that the climate controlled beaches will provide the edge to lure high class tourists through his hotel’s doors which are planned to open in 2010.

Dynamic Tower-Room with a Rotating View

Tuesday, November 25th, 2008

An apartment with a view is coveted property. After a hard day at work, sitting down in front of a panoramic window while sipping a glass of wine is a wonderful way to unwind.

A decent view is hard to come by. Not only that, but when actually given options, it may be hard to decide between the ocean view, city view, west side, or east side facing apartments. The answer: Individual rotating floors. Just make a choice and viola! The apartment slowly turns to face whatever you are in the mood to see that day.

Dubai, home to 1/3 of the world’s cranes, is constantly expanding. High rise buildings, hotels and skyscrapers are popping up like daisies. The latest technology and newest ideas are often used in the building process here, so it is no wonder that the revolutionary, rotating Dynamic Tower, designed by architect Dr. David Fisher, will break ground in Dubai.

The 420 meter (1,380) high tower will be constructed of 80 individual floors, which are divided into luxury apartments, small villas, offices and a hotel. Each section will rotate at various speeds, depending on the owners specifications. This amazing building will take on a life of its own as the individual sections slowly turn next to one another, constantly revolving and never looking exactly the same.

This skyscraper isn’t just going to look pretty, either: It is meant to generate electricity thanks to the wind turbines that will spin between each floor.

The construction technique is yet another feat in itself, making the complicated design amazingly quick to build. Fisher explains that the Dynamic Tower will be “the first skyscraper to be built entirely from prefabricated parts that are custom made in a workshop, resulting in fast construction and substantial cost savings. This approach, known as the Fisher Method, also requires far less workers on the construction site. [To put things into perspective, 2000 workers are typically needed on sites as big as this, but only 80 technicians are required for the tower].” In the end, it only takes 7 days to complete each floor!

Dynamic Tower should be opening its doors as soon as 2010.

Nakheel-Planting Islands

Thursday, June 12th, 2008

Modern technology is evolving at a frightening speed and ambitious scientists are beginning to realize that anything is possible. Less than a century ago, if you’d told anyone that people will travel to the moon, you would have found yourself heading to the nearest psychiatrist, no matter how calmly you relayed that information. Claims of talking to someone on a miniature phone, driving around in a horseless cart, building skyscrapers or seeing moving pictures in a box will have harbored the same results. With todays technology, however, even the most phenomenal natural process can be replicated and according to some, improved.

Volcanoes have been responsible for spewing up islands (formed from massive amounts of magma) since the beginning of time. It is a challenge imagining anything more powerful than an erupting mountain. However, a now infamous United Emirates Development company-Nakheel-had decided to take on the challenge of creating huge man made islands off the Dubai coastline-without any volcanic help.

Cities have been carved out of mountains and forests, it was only a matter of time before we saw islands erected in the ocean. The first of Nakheel’s projects was the Palm Jumeirah, launched in 2001, with more islands currently being added. Palm Jumeirah is already home to 500 families and contains malls, hotels, resorts, schools and parks. Leaving this sanctuary is unnecessary since it provides everything a family would need to live comfortably. According to the Nakheel website: “ When complete, projects such as the Palm Trilogy, the World and Waterfront will add more than 600 miles of beachfront to the Dubai coastline and cover over 2 billion sq ft.”

The idea of building islands is catching on:  Phuket, Thailand is planning to build Zoran, a man made island specifically designed to cater to super yachts. Spain has proposed a Marina development near Gibraltar, while Qatar has already started building “The Pearl” off  its coast. International Listings shows the top 10 man made islands in greater detail. 

With the ability to create something of such proportions comes an environmental responsibility.  Smaller islands have been built in the past, such as Florida’s Venetian Islands built during the 1920s. These islands, built to house more luxurius real estate, connect to the causway that runs from Miami to Miami beach.

Dubai thrives on tourism and as the fastest growing city in the world, is always adding real estate. The addition of 60km per 1km of coastline gives tourists added incentives to visit the country and enjoy the warm waters. Pouring billions of tons of sand onto the ocean floor does not sound like it is doing the ocean ecosystem any favors, even though Nakheel company representatives claim that the corals in the area where mostly dead and with minimal wildlife. This is arguable, especially with the water now murky from the silt, but in Nakheel’s defense, they plan on creating artificial coral habitats, the sand will eventually settle, while the areas between the developed islands have already proven to be ideal habitats for species of sea grasses. Smaller remote islands will be specially created for nesting sea turtles. It is important to note that turtles tend to nest in uninhabited areas making Dubai’s mainland beaches inhospitable to the species. It is in the developers’ best interest to create the ideal habitats for the local wildlife since snorkeling with dolphins, turtles and fish amongst coral reefs and sea grasses adds to the appeal of living on an island.

Looking at the Dubai coast from space, the expansive swirls of land and palm shaped islands seem out of place. It will be interesting to see whether oceanic wildlife will benefit from the expansion, especially with oceanic experts and conservation biologists giving advice to the development team.
