Tall Buildings This site offers an evaluative look at 25 tall buildings throughout the world, including the World Trade Center. The buildings are compared and used to illustrate discussions of skyscraper design issues such as aerodynamics, structural technologies, skins (the outer surfaces), public space, green technologies, and circulation and escape routes.
