Green Style: Hearst Tower

Green Style: Hearst Tower

We were just here today, on the fortieth floor, where the views go out for miles in all directions. It's really a lovely and unconventional building - much more European in feel that you'd expect from a big NYC skyscraper. Designed by Norman Foster, this is the first big building built after 9/11 and the first "green" high rise office building completed in New York City. For more info head below...

Of note:

• The triangular structure is the strongest known to man and allowed them to use 20% less steel than in a conventional frame
• The building circulates rainwater for heating and cooling and for the lobby waterfall
• The lobby fresco by Richard Long was made with mud from the Hudson

From Wikipedia:

"Hearst Tower is the first "green" high rise office building completed in New York City, with a number of environmental considerations built into the plan. The floor of the atrium is paved with heat conductive limestone. Polyethylene tubing is embedded under the floor and filled with circulating water for cooling in the summer and heating in the winter. Rain collected on the roof is stored in a tank in the basement for use in the cooling system, to irrigate plants and for the water sculpture in the main lobby. The building was constructed using 80% recycled steel. Overall, the building has been designed to use 26% less energy than the minimum requirements for the city of New York, and earned a gold designation from the United States Green Building Council's LEED certification program.

The atrium features escalators which run through a 3-story water sculpture titled Icefall, a wide waterfall built with thousands of glass panels, which cools and humidifies the lobby air. The water element is complemented by a 70-foot (21.3 m) tall fresco painting entitled Riverlines by artist Richard Long."
