Skyscrapers

This technology might not be fully appreciated by readers located in earthquake-free locales, but if you've ever felt the ground move beneath your feet you'll be pleased with this technology. At Tokyo Big Sight last week Japanese company THK was demonstrating how their linear motion systems could dampen the shock of an earthquake. One of their systems, when placed underneath an object that you'd like to protect, will absorb most of the shock of an earthquake. Read More

The 71-story Pearl River Tower, described as one of the most energy-efficient skyscrapers in the world, has reached its topping out milestone on the way to its planned completion later this year. (For those not in the architectural know, topping out or topping off is a ceremony held when the last beam is placed at the top of a building.) With a height of 309.6 meters the 2.3-million square-foot Pearl River Tower incorporates the latest green technology and engineering advancements, the most immediately obvious of which will be a pair of openings in the tower’s facade which feed wind turbines to generate energy for the building.

‘Green roofs’- urban rooftops covered with plants - are gaining in popularity to help buildings reduce their reliance on air conditioning, and now scientists in Michigan are reporting they could also help fight global warming by eliminating carbon dioxide in cities, more effectively than was first thought.

In this week's Gizcast, we're privileged to be joined by Dr. Dickson Despommier of New York City, who is perhaps the world's leading expert on Vertical Farming, a topic we've covered several times in the past few years. Dr. Despommier speaks with Loz Blain about the social, economic and environmental issues we'll have to face as the Earth's population jumps to 9 billion in the next 40-50 years. If we keep farming the way we are now, we're simply going to run out of land to feed ourselves - so the solution seems clear: we need to start bringing food production and agriculture into the high-rise age. The farms of the future, it seems, will be skyscrapers. Geoffrey Baird also joins us for a weekly roundup of top stories. Read More

Demand for office and housing space in ever diminishing land space has led to taller and taller buildings reaching for the skies in cities around the world. This shortage of land in many cities has unfortunately also led to a scarcity of natural vegetation in urban settings. We’ve looked at several vertical-farming concepts - dedicated buildings that provide space to grow crops in city centers - but a new architectural system from Vertical Landscapes (VL) seeks to invite nature back into our cities on a broader scale. The architectural system transforms buildings into columns of vegetation to add a much needed touch of green, help clean the city air and possibly even produce small scale crops, all while retaining the building’s usual use for office or housing space.

The Rescue Reel is a compact, self-contained device designed to allow people to escape from high-rise buildings in an emergency. Taking inspiration from a fishing reel, inventor Kevin Stone's design features a simple sling harness and enough cord to descend from a 100 story building, yet the device is small enough to be stored in a standard filing cabinet drawer.

Dubai has well earned its reputation for architectural extravagance and excess. Not a cent has been spared as various developers vie to produce the biggest, the most stunning, the most luxurious and the most outrageous projects ever undertaken. And while this next project is right up there in terms of luxury, exclusivity and head-spinning architectural genius, it adds a fascinating extra dimension - the ability to generate ten times as much power as it will use. Each floor of Dynamic Architecture's wind-powered rotating skyscraper is a single apartment with the ability to rotate independently, giving residents the ability to choose a new view at the touch of a button - quite a party trick. Wind turbines between each floor will generate a vast surplus of electricity capable of powering the whole surrounding neighborhood. Construction is set to begin soon in Dubai, with a second tower to follow in Moscow and numerous other sites around the world being considered. Read More

March 18, 2008 One of the key challenges in urban architecture over the next 50 years will be figuring out how to squeeze vast numbers of additional people into urban areas that are already extremely crowded. London, for example, will somehow have to deal with a projected 100,000 extra inhabitants every year until 2016. The current plan of building new "commuter towns" on the city's outskirts causes a raft of problems - but architecture think tanks are working on ambitious solutions that go vertical instead of horizontal in search of space. Could 100,000 people be comfortably housed in a single structure? Could one building realistically be a whole new town, with schools, parks, public squares and hospitals? Read More

July 31, 2007 The enormous and still skyrocketing wealth centralized in Dubai has seen some absolutely outrageous construction projects taking off. From the world’s tallest building and a ski slope in the desert to custom-built islands and rotating skyscrapers, the international commerce hub seems to have ingenious developers fighting each other over who can make the biggest show of material excess. The latest jewel in Dubai’s extravagant crown will be a 516-metre tall apartment building, more than twice as high as the previous biggest residential building and with no expense spared on pure luxury. Even its name, the Pentominium, drips with treacle-thick exclusivity. Some floors will be uniquely suspended in mid-air, giving the impression that you’re living in a floating penthouse in the sky, with residents having access to a fleet of luxury automobiles and yachts for transport and entertainment. The ancient Egyptians defined their era with the impossible pyramids of Giza – could the fantastical architecture of Dubai be the defining monument of our era? Read More
