Generally lights on a building enhance the beauty when darkness sets in, but what if the lights could be manipulated to send a message across? The Dexia Tower in Brussels, Belgium simply does that with its elaborate setting of lights on the facade. The tower has LED bulbs fitted on 4200 windows, the color of which is controlled by computers.The color coded messages range from the next day’s temperature, cloudiness, precipitations and even wind! For warm temperatures [> the monthly average] the colors used are yellow, orange and red, while the cooler counterparts are denoted by cyan, blue and violet, with green being the median.

The facade can also produce “figures, letters, geometric shapes with various effects and also graphic designs” with the help of these lights.The LEDs on their own are not strong enough to brighten the building. The blinds are closed to reflect the light all over the window. The Dexia Tower thus with its three colorful illuminated facades not only becomes a center of attraction but also sends messages to those near and far-off about the city’s weather in an innovative way.

As of now the duration of the lighting for the tower has been reduced to 10 minutes/hour between sunset and midnight due to the economic crisis.
