The Barcode nightclub was built in a disused brick Victorian railway arch in Vauxhall, south London. The entire nightclub is illuminated using only LED lights, and the sound system is also energy efficient. The architect, Woods Bagot claims that the system consumes less electricity than the power used to boil a kettle. If they could just give a watts per hour figure I'd be happier! Still, this is a interesting example of all-LED lighting in a building, which I'm sure we'll see more in the coming years. Because the LEDs give off very little heat, much less AC is required to cool the building in summer. See more pictures over the fold.
