Shigeru Ban Architects has designed and completed La Seine Musicale in Paris

Shigeru Ban Architects has built a music hall complex on Seguin Island in the western suburbs of Paris that features an environmentally-friendly sail. La Seine Musicale is shaped like an egg and has a grid shell structure, with a large triangular sail covered in solar panels. 

As the sail is mounted on rails, it is mobile and able to follow the path of the sun throughout the day. This provides a solar shield for the lobby behind it so it isn't in direct sunlight and allows for increased efficiency of the panels, which supply the building with energy.
