This is a plaza in Masdar City, the new “green” city in Abu Dhabi, where I’m enjoying a pleasant, cooling breeze.
The breeze is generated by a wind tower, above, which is the centerpiece of the Masdar Institute, a graduate school devoted to sustainability that bills itself as “the Green University.”
The tower isn’t a wind turbine–it doesn’t have blades and or make electricity. Instead, it’s a 147-foot tall structure that uses open and closed louvres and changing weather patterns to draw drafts down to the plaza, which otherwise would be unbearably hot in the summer.
The towe
r is also an energy monitor, tracking usage in the student apartments that overlook the plaza. When the tower’s LED beacon is blue, as it is here, efficiency standards are being met. When it’s red, someone’s AC is blasting.
“That’s my guilt trip right there,” says Martyn Potter, director of operations and facilities at Masdar City. “It’s 45 meters tall.”
Yesterday, traveling with a group of reporters, I took a tour of Masdar City — the audacious, carbon-neutral, zero-waste $15 to $20-billion planned development rising out of the Arabian desert. About $2 billion has been spent so far, much on planning, design and infrastructure.
Announced in 2006, the project has been delayed and downsized by the global financial crisis. For now, it’s barely a spech on the vast urban sprawl of Abu Dhabi–six buildings, on a site no bigger than a couple of football fields. But there’s enough experimentation going on at Masdar City so that it could–could–have implications for clean tech, renewable energy and urban design in the Middle East and elsewhere.
So please join me on my Masdar City tour, illustrated by iPhone images and a Flip movie…
