Green Towers for New York is the title of the ongoing exhibition at the New York City’s Skyscraper Museum, that will be on show until the month of May: the subject is the growing tendency of building low-impact skyscrapers. Among the towers on display there are – to mention only some – One Bryant Park (Cook + Fox Architects), Hearst Tower (Norman Foster), New York Times Building (Renzo Piano), Freedom Tower (SOM) [Business Week].
