To be safe from the winds, a few floors must be left empty. So that the winds could pass through. Such as this 432 Park Avenue building. Apart from this, Burj Khalifa’s foundation, has 192 concrete and steel columns under it. They extend to 50m into the ground. Similarly, the building above ground needed concrete too. Concrete had to be delivered to the very top. To do this, the world’s largest concrete pumps were built so that Burj Khalifa could be built. The exterior of the building uses more than 100,000m² glass as you can see in the photos.
But an even more surprising fact is that the exterior of the Burj Khalifa forms the world’s largest LED screen. This is why you can watch light shows on Burj Khalifa. You can see colourful designs and patterns, and even movie trailers. The entire movie trailer being shown on a building. You might think that this is a projection. That the trailer was being projected onto the building by a projector. It wasn’t.
There are LED lights on the building Such as the tiny LED lights on your computer screens and TV, There are 1.2 million LED lights on this building in total. Each light is quite large. But if you see these 1.2 million LED lights from afar, it’ll feel as if you are watching a TV screen. It enables videos of any length to be played on this building. And you might be wondering that when videos are being played, won’t it create problems for the people inside the Burj Khalifa? Wouldn’t they see films playing on the windows or these lights? No, they won’t.
Next time when you visit the Burj Khalifa during the light show look closely and you’ll notice that these lights aren’t spread out all over the building. They are installed only on the frames. This is sufficient to display videos that can be enjoyed by an audience at a distance.
