Shanghai Tower

Shanghai, China

Shanghai Tower is the second tallest building in the world, standing at 2,073 feet tall. It’s not just amazing to look at—it’s also built to take care of the environment. The building has a special outer layer that traps air, helping to keep the inside cool or warm without using lots of energy.

There are also 270 wind turbines on the outside that make electricity for the lights on the building. Because of these smart ideas, Shanghai Tower uses much less power than other really tall buildings.
