Standing at a recording breaking 2,722 feet tall, Dubai’s Burj Khalifa is the tallest building in the world. Completed in 2010, the Y-shaped structure stands proudly in the heart of Dubai. The architectural marvel was designed by Chicago based Skidmore, Owings and Merrill. The structure’s foundation is supported by 192 piles that drive 164 feet into the ground and engineers had to pour 58,900 cubic yards of concrete in order to keep the massive skyscraper upright. Towering over 160 stories in the air, the Burj Khalifa is covered in 1,870,000 square feet of glass. With all that desert light beaming into the building, the Khalifa utilizes an advanced air conditioning system that draws outside air from the upper floors where the air is cooler. Since the Burj Khalifa houses apartments, hotels, restaurants, businesses and even night clubs, the building requires 57 elevators capable of reaching a top speed of 33 feet per second.
