Nature’s Benz. LA Autoshow reveals a radically green Mercedes-Benz concept called Biome– it’s made of organic fibers, powered by the sun, and releases pure oxygen into the air! The system behind this model is called “Mercedes-Benz Symbiosis,” in which vehicles are seamless part of the ecosystem.

Facebook’s Exodus. According to the New York Times, Facebook is moving out — of the office clusters in Palo Alto — and into an insulated 57-acre corporate campus in Menlo Park, California, which is to be renovated by San Francisco-based Gensler. About 2,000 workers, including Mark Zuckerberg, will be moved in within next 10 months. These young 20-somethings don’t want a sleek corporate office, but something idiosyncratic and soulful, which the new campus aims for.

Code Green. Crain‘s reports that the New York City Council continues to green up the city’s building codes. A trio of bills looks to “create more energy-efficient roofs.” While the first bill requires more reflective and less heat-absorbent roof materials, the second removes building-height limitations from solar thermal equipment and electric collectors and the third bill will add heat and power systems to the list of allowable rooftop structures.

Well-spoken Vowell. Chicago magazine talks to Sarah Vowell about Chicago — and a little New York — architecture. “It’s what I do for fun: Go see buildings. I like architecture because it’s so nonverbal,” she said, and then goes on to discuss her personal relationship with the Carson Pirie-Scott Building. Vowell recently finished her new book on Hawaii called Unfamiliar Fishes.
