The handsome Hearst Tower skyscraper achieved LEED Gold accreditation from the USGBC–it’s the first to be recognized as such in New York City.  The building architect is the famous Norman Foster, and this is the third time for Jetson Green to feature one of his buildings (30 St Mary Axe + WTC 200 Greenwich).  Norman Foster is literally one of the leading architects in the modern/contemporary + green building field.  This building is particularly bold for its environmental mission: it used 80% recycled steel and will consume 25% less energy than its skyscraper counterparts. 

Green Features:
The green features of Hearst Tower reflect the environmental commitment and vision of Hearst Corporation–a leading corporation with interests in magazines (O, The Oprah Magazine, Popular Mechanics, Cosmopolitan, + Esquire), newspapers (San Francisco Chronicle, Seattle Post-Intelligencer), broadcasting, entertainment television (ESPN, ESPN2, Lifetime, A&E, + The History Channel), and interactive media (broadcast dot com, iVillage, XM Satellite Radio).  We are talking about a huge company taking a pro-active step to provide high-caliber, environmentally-friendly working spaces. 

    About 85% of the original structure was recycled for future building The "diagrid" system (diagonal + grid) eliminates the need for verticle steel beams, which provides structural efficiency and greater use of natural lightUsing the diagrid system required 20% less steel (a 2,000 ton savings in steel)Foreign-sourced materials accounted for less than 10% of the total cost of constructionLow-E coated glass on the exterior of the building allow natural light into the building sans heatInternal light sensors control the balance of artificial and natural lightActivity sensors adjust the system and turn off lights and computers when systems aren’t in useThe roof collects rainwater and reduces the amount of rainwater that dumps into NYC’s sewer system by 25%A 14,000 gallon water reclamation tank in the basement provides 50% of the buildings water needsHarvested water is used for the "Icefall"–a 3-story sculpted water feature (also the nation’s largest sustainable water feature) that will humidify and cool the atriumWalls were painted with low-VOC paint, workstations were built without formaldehyde, and concrete surfaces were finished with low toxicity sealantsFloors and ceiling tiles are manufactured with recycled content
