During daytime Dexia tower in Brussels is an ordinary building, but at night it becomes a light show. The building can be used to show tomorrows weather – temperature and wind. It sure bits watching the weather channel. It’s also possible to make you own light show from a touch screen near the building. Here’s how it works the 4,200 of 6,000 windows have lighting installations consisting of 12 light bulbs, each with 3 LEDs – a green, a red and a blue. Also these windows have special blinds when closed allow the LED’s to illuminate the whole window. Dexia tower is also energy efficient, 1 LED uses 1 watt.
