In 2009, one of the most eagerly anticipated buildings in the last 20 years was to be completed: The headquarters of CCTV in Beijing, designed by Rem Koolhaas and OMA.

A striking, integral piece of that complex was the nearby Mandarin Oriental Hotel. Sadly, it looks like the hotel has almost completely burned down this morning.

"Flames 20-30 feet high shot out of the building, just north of the landmark CCTV tower designed by Dutch architect Rem Koolhaas. The flames were reflected in the tower, which itself appeared to be untouched. No one appeared to have been in the building, a policeman on the scene said, adding he had no immediate knowledge of any casualties. The destroyed building housed the Mandarin Oriental hotel in eastern Beijing, which was supposed to open in 2009. The fire department did not immediately comment on the suspected cause of the blaze."

Here's a video of the entire complex, and a series of views of the MO Hotel:

Concrete is a familiar substance. Its durable nature and versatile applications have made its usage ubiquitous throughout our cities. However this primary building material is also extremely energy intensive to make and transport, and produces a significant amount of the world’s greenhouse gas emissions. Can the omnipresent grey substance ever be reconciled as a green building material?

Concrete’s impact on the environment starts when limestone is blasted in quarries to make cement - the binder, or substance that sets and hardens it into a useful building material. Cement accounts for 7 to 15% of concrete’s total mass by weight and is made by superheating (in coal-fired kilns) a mixture of limestone and clay and then grinding the resulting substance into a powder. When this power mixes with water, it forms strong calcium-silicate-hydrate bonds that can bind other particulates, like sand or gravel, to make concrete. The cement-to-water ratio determines the strength of the concrete.

Once limestone has been blasted and mined it is then transported to a cement plant, where the fuels used by the plant and machinery produce CO2 emissions. Next the limestone, or calcium carbonate, releases CO2 when it is heated to make the cement. Forty percent of CO2 emissions from the cement plant come from the combustion process and Sixty Percent of CO2 emissions come from the calcination process, according to the Cement Sustainability Initiative report produced by members of the concrete industry. The report also says that since calcination is intrinsic to the process, they must focus on reducing energy use associated with the manufacture of concrete.

So what does concrete have going for it?

It lasts. This is the stuff the Romans built their empire with. Concrete is highly resistant to heating and thawing. It’s impermeable to air and wind-driven rain. And concrete is inedible, so bugs and vermin can’t gnaw at it. This durability means that a building can preserve its concrete foundation or concrete exterior while replacing less durable parts like windows, insulation and plumbing (you get a point from LEED if you reuse a building).

A building with exterior concrete walls can also be energy-efficient, especially in climates that have daily temperature fluctuations. Even though concrete provides little insulation, it creates thermal mass that can store warmth or cold, reducing indoor temperature fluctuation. White concrete also reflects heat and can mitigate the urban heat island effect.

A Locally-Sourced Material: Another reason concrete is so popular is because the raw materials to make it are prevalent in most of the world. For the eco-conscious builder, this means it can be locally-sourced, reducing CO2 emissions from transportation. Of course, “local” is a relative term – advocates in the cement industry claim that “the cement, aggregates, and reinforcing steel used to make concrete and the raw materials used to manufacture cement are usually obtained or extracted from sources within 300 miles of the ready mixed, precast concrete, or masonry plant.”

Concrete can also be be recycled – to a point. The concrete industry web site concretethinker.com says: “Most concrete in urban areas is recycled as fill or road base and not placed in landfills. Concrete pieces from demolished structures can also be reused to protect shorelines, for example in gabion walls or as rip rap.” Used concrete can also be reused as the aggregates in new concrete. Concrete’s recyclability is limited because its chemical properties change over time and with each processing. Other materials can be recycled as aggregates in concrete.

Canadian environmental consultants, Carbon Sense Solutions, may have just developed a carbon storage method that could reduce global CO2 emissions by as much as 1% a year. Their new method called, CO2 Accelerated Concrete Curing, accelerates the curing process and stores carbon dioxide at the same time. This method applies only to precast concrete, but has the potential to make a huge impact on the world.

The method, also known as concrete carbonation, actually occurs naturally as concrete cures, but up until now has not been considered economical. Carbon Sense Solutions says it has developed a faster way to store more CO2 in concrete, using off the shelf technology, which uses dramatically less energy. They also claim the concrete is more durable, more resistant to shrinking and cracking, and less permeable to water.

As concrete is used more than any other man made material on earth, (the Chinese alone consume 40%!), and concrete is responsible for upwards of 5% of global CO2 emissions, any amount of increase carbon storage in concrete would make a difference. So if Carbon Sense can really deliver as they say it can in Technology Review, the process “has the potential to sequester or avoid 20% of all cement-industry carbon dioxide emissions.”
That’s some carbon sucking concrete.

We are certainly facing an economic crisis like most of us have never seen before, and the signs can be seen all over the world, but are we reaching the extreme of offering valuable services for close to nothing? Or is this a clear case of a genius idea that we have never thought of before?

"I'm serious," John Morefield said, laughing when asked about his booth, which has appeared two weeks in a row at the open-air street market in old Ballard. "I'm here to answer questions. And I do charge a nickel. I've made a dollar today so far."

Twice laid off from architectural firms in the past year when work dried up, the 27-year-old was inspired by a public radio program's "Ask an Iraqi" show and Lucy's psychiatric help stand in the comic "Peanuts." Morefield decided to set up a booth, offer cheap advice on home remodeling - and hope the contacts would turn into design jobs.

So he built the small stand and painted his sign. He packed up his draftsman tools and laptop (for mapping research that extends beyond the top of his head) and set out. He secured space with market organizers, and brought a stool and a warm coat.

The more I think of it, the more I realise that it was an excellent idea. "It will never pay off", you might say; but the truth is that this guy has already had news coverage from the blogosphere, some newapapers... and on top of this discreet fame and attention he is getting, he still has the chance of finding some job opportunities amongst the people he talks to in the street. So, in a way, it has paid off already.
A genius is an individual who successfully applies a previously unknown technique in the production of a work of art, science or calculation... according to wikipedia, this guy is Einstein. Lets wait and see.

Eco-enthusiasts will soon have a new eco-paradise island to escape to! Bonaire, a part of the Netherlands Antilles, will be the first island in the Caribbean with a 100% sustainable energy supply. In 2007 the local government of Bonaire, who prides on its island’s beauty and natural preservation, agreed to this ambitious project of trashing its fossil fuel energy dependence and developing an energy system comprised of an 11MW wind farm, 14MW biodiesel plant, and a 3.5MW backup battery. Ecopower Bonaire BV, a consortium of Dutch-German companies, Evelop, Enercon, and local Bonaire Water and Energy Company, is spearheading this project that is expected to finish at the end of 2009.

The project developers first installed a pilot 330kW wind turbine, whose current energy production exceeds any of their initial expectations. As a result, 12 more 0.9MW wind turbines will be installed on the north coast of the island, where wind and surf conditions are most ideal. This wind farm alone can meet the energy demands of the island’s 15,000 permanent residents! Still, five bio-diesel generators are under construction for added stability, and developers expect the switchover from conventional fuels to bio-fuels within 3 years of operation.
Like its neighboring islands such as Aruba and Curacao, Bonaire’s economy is heavily reliant on tourism. Bonaire has strategically developed its land span of 111 sq. miles and the surrounding coral reed for tourism and eco-tourism, making it a top ranked Caribbean destination for scuba diving and witnessing wildlife. The island’s north side is also home to an array of flamingos, a donkey sanctuary and an ecological preserve. With beautiful beaches, great snorkelling, and 100% sustainable energy supply, what more could an eco-enthusiast ask for on her eco-holiday?

Hosted by Core77 and Inhabitat in partnership with the Consumer Electronics Association, this year’s Greener Gadgets Design Competition produced an incredible crop of entries from a worldwide community of designers. After sorting through hundreds of promising entries the choices are narrowed down to 50 top picks...

This one is my personal favourite:

Blight




Description

The sun provides us with energy every day. How can we use it directly for indoor applications? Blight is an optimal indoor lighting solution that is able to replace current lamps without any need of electric supply. With Blight we have not produced a new object; we have just created the design of an everlasting product: the Venetian blind. We use all the current functions of this object and add a little technology to give it a new function - to catch solar energy and convert it into electricity.

This solar blind creates a link between indoor and outdoor, taking the daylight during the day and giving it back at night. The advantage of the Venetian blind is to have a large surface exposed to sunlight in a small, cumbersome object. With the revolving blades we can follow the course of the sun in order to catch a maximum of energy. Moreover we can adjust the position of the lamp to obtain various lighting effects. The produced energy can be used to supply a computer or other devices, by means of an inverter.

The object will combine two newly-discovered technologies: Flexible solar cells, and electroluminescent foil which requires little energy. Blight is durable and ecological because power cables are not needed and solar power is clean. This improved Venetian blind could be used in the household as well as in office applications.

Carbon Neutral master plans are being adopted in several countries, in times when energy and emissions are becoming very important.

And that´s exactly what Azerbaijan will do to develop Zira Island on the Caspian Sea, located in the bay of the capital city Baku. The master plan was developed with danish BIG Architects and Ramboll engineers, with an architectural proposal based upon the country’s dramatic natural setting.

In the words of Bjarke Ingels, the proposal for Zira Island [...] is an architectural landscape based on the natural landscape of Azerbaijan. This new architecture not only recreates the iconic silhouettes of the seven peaks, but more importantly creates an autonomous ecosystem where the flow of air, water, heat and energy are channeled in almost natural ways. A mountain creates biotopes and eco-niches, it channels water and stores heat, it provides viewpoints and valleys, access and shelter. The Seven Peaks of Azerbaijan are not only metaphors, but actual living models of the mountainous ecosystems of Azerbaijan.

This mountain concept may sound strange, but BIG has developed this in the past as you can see on Mountain Dwellings.
As you can see on the images, this urbanized peaks that Bjarke describes are derived from the geometry of famous mountains in the country, and each peak becomes a unit of private and public mixed uses. The result is an organic skyline that merges buildings with the natural topography of the island. Among the peaks, there´s a public central valley that connects a series of private resort villages and the beaches. Also, a public trekking path connects the mountains and allows the visitors to scale up to the top. It also includes 300 private villas that take advantage of their setting with panoramic views out over the Caspian Sea.

But the main highlight of this masterplan was to make the Zira Island completly independent of external resources, achieved through the mix of traditional Azerbaijani building tradition and new technologies. The aim is to provide a high-end living wiht a minimum usage of the resources.

This strategy includes several aspects:




SUN
The buildings of the island are heated and cooled by heat pumps connecting to the surrounding Caspian Sea. Solar heat panels integrated in the architecture create a steady supply of hot water, while photovoltaics on strategically located facades and roof tops power daytime functions as swimming pools and aqua parks.

WATER
Waste water and storm water is collected and led to a waste water treatment plant, where it is then cleaned, processed and recycled for irrigation. The solid parts of the waste water are processed and composted and finally turned into top soil, fertilizing the island. The constant irrigation and fertilizing of the island supports the lush green condition of a tropical island, with a minimal ecological footprint.

WIND
Zira Zero Island benefits from the fact that Baku is “the city of wind”. By harvesting the wind energy through an offshore wind farm, the island will have its own CO2-neutral power supply. Further by locating the wind turbines on sea, it transforms the existing offshore oil industry’s platforms & foundations in Baku into a more sustainable future of wind turbine platforms.

LANDSCAPE
The landscaping of the island is derived from wind simulations of the microclimates created by the mountains. Swirly patterns created by the wind moving its way through the Seven Peaks inform the planting of trees and the design of public spaces. Where the winds and turbulence are strongest the trees becomes denser, creating lower wind speeds and thus a comfortable outdoor leisure climate.

Forget about wandering through an art gallery and wondering if you’re the only one who has no idea what anything means. Hannes Broecker has brilliantly invited the cultural elite to grab a glass at an exhibition in Dresden, Germany, and drink away the art.

Regardless of what we do or do not understand about art, we can all agree, it stimulates our senses. Broecker has aroused our sense of taste (not to mention eliminated the need of elbowing our way to the bar) by hanging flat, glass containers with a variety of cocktails in the exhibition space. As the night progressed, the levels of the multi-coloured infusions diminished. By the end of the event, the art, itself, ran dry, and empty drinking glasses were returned to where they were originally placed.

The joint submission by Foster & Partners and Aston Martin has won first prize, alongside Capoco Design, in Transport for London’s competition to design a new bus for the capital. The two iconic British brands worked together to challenge preconceptions of bus design with a vehicle that is environmentally sensitive, accessible, convivial and reinvents a much-loved symbol of London for the modern era.

The winning designs make imaginative use of hybrid-drive technology, lightweight materials and a wealth of fresh engineering ideas. The designs pay homage to the well-known shape of the Routemaster, a particularly fine city bus that defied fashion and changes in the ownership and control of London’s buses.

Lord Foster said:
“I am delighted that we have won joint first prize with the Aston Martin/Foster + Partners design. This project has really captured my imagination. London’s buses are so much a part of the essence of this city – functionally, symbolically and geographically. They help us draw a mental map – their destinations are London’s historic places, often green: Shepherds Bush, Islington Green, Hampstead Heath, Green Park. Our design seeks to combine contemporary innovation with timelessness. Like the original Routemaster – which was ahead of its time and consequently endured – a new bus for London should establish a whole new travel experience that espouses 21st century aspirations, while celebrating the memory and the experience of the original.”

After a two-phase international competition (with offices such as Morphosis, Abalos+Sentkiewicz, MVRDV and Zaha Hadid), OMA has been awarded the first prize in the design competition to build the new Taipei Performing Arts Centre.

The project, led by Rem Koolhaas and Ole Scheeren, is based on 3 theaters (1 x 1,500 seats - the round one, 2 x 800 seats - cubes) which are plugged into a central cube cladded with corrugated glass. This scheme puts all the stage accommodations of the 3 theaters into the central cube, allowing for more flexibility as theaters can be used independently or combined, expanding the possibilities for experimental performances - an art which is very strong on the country. This new arrangement of stage and seatings includes a public circulation that exposes parts of the backstage to the public.
