Green walls are becoming more and more common place in cities across the world. However, they are usually implemented as apart of a new architectural design rather than an existing building. Until recently when a 2,380 square-foot, six storey high green wall was installed by PNC on their existing corporate headquarters in Pittsburgh. The wall is a modular design and is two foot by two foot panels(approx. 600 x 600mm). The wall was installed by Green Living Technologies and according to the video below is the largest green wall in North America and is planted with different plant species that will create an evergreen wall all year around.
Carolyn Steel recently gave a presentation at TED Global 2009 in Oxford, UK last July.
Architect and author Carolyn Steel uses food as a medium to “read” cities and understand how they work. In her book Hungry City she traces — and puts into historical context — food’s journey from land to urban table and thence to sewer. Cities, like people, are what they eat.
The video was recently posted and Carolyn gives a great presentation and some great insights.
The two famous windmills in Golden Gate Park could soon have a lot of company as a broad array of city officials, business leaders and environmentalists push for streamlined, modern versions to spring up at famous spots all over the city.
Wind turbines could soon be built at Twin Peaks, Treasure Island, the Civic Center, Ocean Beach, the San Francisco Zoo, city parks and the airport as demonstration sites for how urban wind farms could help power San Francisco – and to educate residents in the hopes they’ll put them on their rooftops.
