Measuring 145 metres from top to bottom and counting 38 floors, Dexia Tower is the third highest building in , . In the middle of the Rogier Square the building shines like a beacon over the town. The Tower is visible from several major traffic arteries in the capital and is situated precisely in the middle of the Mint Square – North Station axis.

It has a trapezium-shaped footprint covering an area of 4,400 square metres

Designed by lab-au, the installation uses a dozen LEDs in each window, making the whole building look like a big Lite Brite canvas. The temperature is shown based on the monthly average and a different color represents each increase or decrease. There also apparently is some color code for depicting humidity, wind speed and precipitation, but it beats us.

NOTE: According to the Dexia Towers website, the lighting of the weather forecast lights has been drastically reduced due to the economic and financial conditions. Between sunset and midnight, the lights will only illuminate for 10 minutes per hour. Well, we guess that takes care of that.

    A pretty obvious question: why all shots are night shots? It doesn’t look that impressive during the day? Or maybe the way it looks during the day is not even worth a shot? :)

    Wow! That’s beautiful. And so much better for the planet to use LED lighting. I work for Sharp and they have entered the market for LEDs. Their LED lamps offer high quality light, versatility in color and long life. I really think it’s the lighting for the future.

    To me, this does not seem to be an integrated design element within the facade, but rather just a decoration. Add the fact that they only light them up 10 minutes an hour and I’m lead to believe a much more restrained use of LEDs within an integrated facade would have been much better. Right now it seems like just a gimmick.
