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.

Moses Project Planned to Part Venice Floods

Monday, December 15th, 2008

Venice floods more than one hundred times a year. At the beginning of this month, Venice was caught in another onslaught, as the sea level around the city rose higher than most people can remember. The last time locals and countless visitors had to wade through water this deep was over thirty years ago. It is floods like the most recent one that make it clear how important a flood barrier really is.

Things were different a century ago when floods occurred at an average of ten times a year, but Venice has always been sensitive to changes in water levels because the city itself is built on hundreds of small islands. It doesn’t help that Venice is sinking a few centimeters every year, as well.

One proposed solution comes in the form of a barrier that would use hydraulic pressure to raise steel plates that cut off the rising water flow. This controversial Moses Project-named after the religious figure who parted the red sea-was originally shelved because of the 4.2 billion dollar price tag and the millions (if not billions) of dollars it would take to maintain the structure annually. The hefty price tag isn’t the only cause for concern,  environmentalists worry that the artificial barriers will harm protected ecosystems. They claim that closing off the tide flow will cause water to stagnate and kill off marine life.

In an in-depth article by the Times, journalist Richard Owen explains that  the project “involves 79,300-tonne hinged steel panels or “buoyancy flap gates”, which most of the time will lie beneath the water but will fill with compressed air when the high-tide alarm sounds, closing off the three inlets. There are 700 workers at the three construction sites, a workforce due to double as completion approaches in 2012. A €1.5 million simulator at Malamocco shows how the locks will allow shipping to pass when the lagoon is blocked off.”

Any barrier that affects the natural flow of floods and tides will obviously have an impact on the underwater ecosystems. The question is how much of an effect? Not only that, but shouldn’t the ancient historical architecture be protected as well? Either way, Moses is currently scheduled for completion in 2012.

Overall land subsidence in the region surrounding Venice has
been 1.5 to 2.0 meters during the past 70 years, making high
tides far more problematic (ref. Wessex Institute).

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.

Greenhouse Provides Glimpses into Past, Present and Future

Tuesday, October 14th, 2008

Riyadh, Saudi Arabia’s capitol, has slowly transformed into a sprawling city over the years, full of silver skyscrapers and modern buildings. The city is home to over 5 million inhabitants and bears little resemblance to the land that used to be covered with date trees and orchards. Riyadh roughly translates to “garden” in Arabic and it is a suitable name for a region with such fertile soil.

It is only fitting that the world’s largest greenhouse will reside in the garden city of Saudi Arabia. Barton Willmore, a British design and architectural planning company is working with the civil engineers at Buro Happold to create the 160 hectare King Abdullah International Gardens (KAIG).

This garden will be housed in two giant interlocking crescent domes with 120ft high ceilings. Costing almost a million dollars per hectare, KAIG will do more than just house a variety of pretty plants: The structure is meant to showcase the various global ecosystems with an underlying lesson in sustainable development.

The high domes eliminate the need for constant air-conditioning by allowing the hot air to float to the ceiling, trapping the cool air below. Rainwater is harvested and stored in underground reservoirs and used for irrigation. Solar panels and wind turbines will generate a large portion of the electricity needed to power the structure.

Once the project is completed in 2010, visitors will walk through a wide range of gardens meant to illustrate the evolutionary history of plants, current ecosystems and finally, the earth’s potential in the future. The last exhibit-”The Garden of Choices” - allows those interested to see how today’s choices directly impact global ecosystems. Various paths stimulate what the world would look like depending on the choices made: visitors zig-zag through lush gardens indicating what would eventually become reality if new environmentally friendly technologies and ideals were adopted.  These gardens gradually recede and transform into an unappealing dry and charred landscape to indicate what would potentially happen with indifference and the continued trends of pollution.

KAIG will hopefully educate visitors in making the right environmental choices, but even if that isn’t the case, at least this man-made wonder will provide breathtaking glimpses into the earth’s botanical past, present and potential future.

Building Blocks for Better Buildings

Wednesday, October 1st, 2008

The great mosque of Djenne looms over one of the larger marketplaces in Mali, Africa. On the flat brown flood planes, mud walls up to 24 inches thick bear the weight of what looks like a giant sand castle. Protruding from the structure are carefully placed wooden poles and ostrich eggs adorn the tips of the spires at the mosque entrance.

A mosque has stood in the spot since the 13th century. This is quite a feat since the incredible structure is made from nothing more than sun-baked mud bricks and mud. The original mud used for the mosque fell to the ground centuries ago and the current structure has stood in its place since 1906, but the size and overall strength of the building proves that the right mixture of sand, water, straw and gravel has immense potential as a building material.

Integrity Block has developed a modern version of the ancient mudbrick that is perfect for today’s architectural and landscape design. The company specializes in manufacturing green building alternatives and, as proudly stated on their website, “has developed the first green replacement for concrete blocks.”

The Great Mosque of Djenné, Mali, is the
largest mud brick building in the world.

Designing a brick takes more than just throwing a few ingredients together. It took the company two years of research and development before finding the perfect balance which allowed for easy production, and structural integrity.

Unlike the bricks used in mud huts and mosques that need annual replacement or patching up, the Integrity Block has the same strength and durability of cement.

Not only that, but the blocks are in fact a step up from the cement blocks: They are much easier to produce than traditional bricks, requiring less than half the energy of concrete production. It is also made up of 50% pre-recycled content and can generate LEED credits. The LEED (standing for Leadership in Energy and Environmental Design) system, rates buildings at a variety of levels depending on their environmental performance. The higher a building’s rating, the easier a building is to lease or sell since this also implies that the building uses less energy for such tasks as heating, cooling and lighting. More information on specific LEED credits here.

Integrity Blocks improve a home’s temperature regulations, for example, by storing heat during the day (keeping the indoors cool) and releasing the stored heat at night. They are also excellent barriers against outdoor noise.

Sometimes it’s good to go back to the basics.

Solatube - Room Brightening Tunnels

Thursday, July 31st, 2008

Nothing beats natural light. And nothing is more depressing than a gloomy room forced into darkness by the neighbor’s wall. Windows help add warmth to any room, while the natural lighting allows homeowners to run around the house without the need to turn on as many lights. Not only that, but the ventilation provided by an open window slows the growth of the fuzzy green molds known for taking over the soggy windowless bathroom walls found in your first apartment and many dorms.

Solatube International, founded in the early 80s and one of the first companies to design a tubular daylighting system, allows homeowners to bring natural light to any part of their home by running a flexible tube from their roofs to other areas of the building. Extra windows and skylights are a burden to install and can be incredibly costly. Not only that, but small bathrooms, centralized rooms and hallways may not have space or the option of installing an extra window. Solatube uses light reflective technology that forces light to reflect down a tube that can wind into practically any room of the house. The length of the tube is limited to 12 meters which is long enough to travel from the roof to the ceiling of your room. The light reflected out of the glass plated end of the tube (which looks just like an electric light) is comparable to the lighting power of a much larger sunroof.

Light isn’t the only thing Solartube has to offer: These unobtrusive systems come with optional ventilation systems-perfect for a stuffy bathroom or hot, moisture absorbing attic. The solar powered versions ensure that the electric bill is reduced even farther by using a quiet fan that takes advantage of a no-cost renewable resource.

Over-lighting may be a concern to those who may want a dimmer setting for a relaxing bath or warmly lit hallway. This isn’t a problem either, with the optional dimming system.

One of the best things about Solatube is how easy it is to install. According the Solartube website “They require no structural reframing, tunneling, drywalling or painting. A professional can install the product in less than two hours and most Do-It-Yourselfers can finish the project in one day.”

The only problem so far, are overzealous homeowner installing way too many of these wonderfully innovative systems in their homes.

Masdar-Zero Pollution City Living

Wednesday, July 9th, 2008

It isn’t fog that rolls down the hill these days, but smog. Cars spill noxious fumes out their tailpipes and factories send plumes of smoke into the air. It has come to the point where holding your breath is the only solution when wandering across the street or between shops. These problems won’t exist in Masdar, Abu Dhabi the world’s first carbon neutral city.

Launched in 2007, the completion of this highly ambitious plan will occur around 2020. No cars or any other polluting vehicles are allowed in the city, waste and water are recycled, while recyclable plastics and cement will be used during construction. It is estimated that up to 80% of water used during irrigation will be recycled: water seeps through the earth and while some is absorbed by the plants, the rest will flow into a collection area to be reused again later, while fencing used during construction will eventually be resold and recycled.

Foster and Partners, an architectural company focused on design and function, planned Masdar: “Rooted in a carbon neutral ambition, the city itself is car free. With a maximum distance of 200m to the nearest transport link and amenities, the compact network of streets encourages walking and is complemented by a personalized rapid transport system. The shaded walkways and narrow streets will create a pedestrian-friendly environment in the context of Abu Dhabi’s extreme climate. It also articulates the tightly planned, compact nature of traditional walled cities. With expansion carefully planned, the surrounding land will contain wind, photovoltaic farms, research fields and plantations, so that the city will be entirely self-sustaining.”

The tightly packed city will resemble stereotypical Arabian style fused with modern technology-almost comparable to scenes from the jetsons. Visitors and inhabitants will need to get around on foot, bikes, segways or use the underground personal transit system to get around within Masdar’s walls. This isn’t as restricting as it sounds. For example, the solar powered personal rapid transit system (PRT) doesn’t follow a fixed route, but rather takes its load of passengers (up to 6) to any of the 1500 proposed stations throughout the area.

Trees planted throughout the city will provide the 50,000-100,000 inhabitants relief from the desert’s bright rays while numerous fountains add aesthetic appeal and humidify the dry air.

Building planners are taking task of building a zero-emission city seriously, and it seems feasible with the help of partners such as

  • Europlasma-a company that provides a technology that turns toxic ashes to glass and garbage to fuel;
  • Solyndra-a company providing one of the world’s most efficient solar panels;
  • Segway-company of the famous single passenger standing scooter; and
  • Bioregional-an independant environmental organization hired to calculate the carbon footprint left by Masdar’s various stages of development.

Skeptics claim that no city could ever be completely carbon neutral and that an exorbitant amount of energy is wasted making products like solar panels and personal transportation vehicles. This may be the case, but one should look at the bigger picture: Masdar is an experiment and improvements will always be made with technology.

The many years of waste-free living provided by the city will eventually offset the energy consumed during its production, as well. Costa Rica, Norway and Libya have also shown an interest in developing their own zero-carbon cities. It is nice to hear that some people aren’t just wasting their breath when it comes to discussing pollution, but actually trying to do something about it.
