Sears Tower Spending $145 Million On Green - Turbines, Solar In Mix

Sears Tower in Chicago is planning a green makeover to further reduce its energy use by 10 percent.  The skyscraper has already reduced energy consumption by 50 percent since it was built in 1973, Building reports.

Adrian Smith, one of the architects overseeing the plan, says the project is expected to cost over $145 million. The plan includes installing wind turbines and PV on the roof, as well as incorporating new lighting systems, extra insulation and a green roof.

In August, New York City Mayor Michael Bloomberg proposed installing wind turbines on the top of New York City’s skyscrapers.

Boston recently launched a pilot program that saw 34 Boston skyscrapers turning off the lights above their 30th floors between 11 p.m. and 5 a.m. The program could save the city about 25 percent in energy used for lighting.
