The Sears Tower is getting set to undergo a massive 350 million dollar green overhaul, and will be installing wind turbines, solar panels and roof gardens to help complete the task. The five-year project would reduce the tower’s electricity use by 80% and save 24 million gallons of water a year, according to the building’s owners and architects.

“Our plans are very ambitious,” said John Huston of American Landmark Properties, who represents the building ownership. “Our plans to modernize and transform this icon will re-establish Sears Tower as a leader, a pioneer.”

This eco-friendly project includes the installation of solar panels on the tower’s 90th floor roof to heat water used in the building. A number of different kinds of wind turbines will be positioned on the tower’s tiered roofs and tested for efficiency. Around 35,000 square feet of roof gardens will be planted.

“This endeavor is incredibly important as a role model for others to follow,” architect Adrian Smith said. “We see this as a groundbreaking opportunity.”
