The tallest building in the U.S. is going solar.

The Willis Tower, which once went by the much more famous title of Sears Tower, has 1,451 feet worth of windows that, until now, were actually somewhat of an energy suck.

As part of a pilot program, the entire south side of the 56th floor has been fitted with Pythagoras Solar transparent solar-powered windows. The company sites that these photovoltaic glass units (PVGU) provide a triple benefit – energy efficiency, energy generation and they look pretty.

Not only does the unit act as a sunshade to keep cooling costs down, but it also harnesses about as much solar power as a normal roof-mounted photovoltaic.

If the program is successful, enough solar windows might be added to Willis Tower to amount to a 10-acre solar plant and provide nearly two megawatts of solar power.
