In addition to stories about fast food chains cleaning up their store's interiors with (knockoffs of) high design and some ideas about what doesn't make an icon are some interesting TreeHugger-related stories, ideas and companies.

Also, Nanjing, China's soon-to-be-completed 761-foot-tall Jinao Tower gets some love (page 32) for both its smart design -- its innovative use of X-bracing makes it less vulnerable to the flexing that comes with seasonal climate shifts, seismic activity and the speedy winds aloft -- and for its resource and materials efficiency -- SOM Architects' sandwiched glass walls effectively create a thermos, reducing the need for heating and cooling by about 20 percent. Additionally, the design of the building including what essentially amounts to a self-propelled exhaust system, using horizontal air slots every four floors that sucks air in the windward side and exhausts it through the leeward side...cool.
