The Sears Tower Goes Green

We see a lot of plans for new green buildings but an existing iconic tower is getting an eco-makeover. The famous Sears tower in Chicago was the world's tallest skyscraper when it was built in 1973. The new plan calls for installing wind turbines and PV to reduce energy use by 10% (the building has already reduced energy consumption by 50%). Adrian Smith of Adrian Smith + Gordon Gill Architecture spoke about the project at this week's Cityscape conference and said it also calls for new lighting systems, extra insulation and a green roof. The Building website has video of Smith talking about the greenification which is expected to cost over $145 million.
