Aside from a stunningly elegant design what makes this building so special is, for starters, the fact that it generates power for its own construction even as it is being built. The roof, assembled first, is covered with solar panels that will harness energy well before the rest of the building is completed. When finished, the structure will have the lowest power consumption per foot of any building in the world – and will ultimately generate far more energy that it consumes. (Source)
