The hot environment also caused condensation, and the building emitted around 15 million gallons of water. To compensate, a separate pipe system was built to carry water to a tank in the basement. 3. Another structural difficulty that the Burj Khalifa experienced during construction was wind loads. The tower is over 1,000 feet tall, which makes it a major attraction on its own. However, the location of the tower on the beach means that it faces into the ocean breeze most days of the year. This can cause problems for the foundation since more sand is pushed up against the side of the building than expected, which causes the ground under the building to cave in.
In addition to these issues, construction of the building was complicated by the fact that it had to be done above sea level. This required special permits from the government since some parts of Dubai lie beyond the reach of high tide.
Finally, construction of the building was delayed because they ran out of steel when it came time to build the spire. The tower is made up of several elements, including the bulb at the top which tips the scale at 459 feet. It is this piece that gives the building its name: the Burj Khalifa (Palace of the Khalifas).
The Burj Khalifa will be powered by solar panels. The world's tallest building employs solar panels to heat 14,000 litres of water every day, which is delivered to houses and business units within the structure. This provides hot water for showers, laundry, and other operations.
Solar energy is renewable but electricity from sunrays isn't always available when we need it. Solar cells can help offset this problem by storing energy produced during times of excess power production and releasing it when needed. The Burj Khalifa achieves this feat with batteries that store the energy from the sun during the day and release it at night or in the middle of the day when there is more demand for electricity. These batteries are made of low-cost materials that don't degrade over time.
More than 10 million people live within 20 minutes' drive of the Dubai Mall, making it one of the most densely populated cities in the world. In addition to being a source of revenue, the Dubai Mall uses its proximity to serve as a test site for innovative technologies that may later be used in future projects. For example, the mall uses LED lights that use 75% less energy than traditional lights. It also tests green technology such as solar-powered air conditioning.
The world's first solar-powered hotel was built several miles from here on Dubai Island, United Arab Emirates.
One of the first obstacles for the Burj Khalifa was that it had to survive tremendous heat, with temperatures reaching higher than 50 degrees Celsius in the summer. To compensate, an outside cladding of reflective glass with aluminum and textured stainless steel panels was constructed. The building also uses a large number of air conditioners to maintain a constant temperature within its walls.
In addition to this, the structure has to deal with high winds, heavy rain, and snow. So to protect itself, the tower is surrounded by a wall 1.8 miles around. This wall contains over 14,000 liters of water that serves as a wind-protection system for the building.
The world's tallest freestanding structure, the Burj Khalifa has been built close to Dubai Creek and its waterfront location means that it enjoys frequent windstorms. These windstorms can reach speeds of up to 220 kilometers per hour, which is enough to cause considerable damage to any nearby building. To prevent this, the builder decided to erect the tower close to shore so that if it does suffer damage, it will be repairable.
The main ingredient used in its construction is steel. It makes up 75% of the building's weight, with ordinary concrete used to cover it up. The rest of the material used includes arsenic trioxide for its anti-corrosion properties and titanium dioxide for its light coloration.
Furthermore, the Burj Khalifa is designed to operate like a stiffened rod, with cross-bracing beams and braced panels capable of withstanding earthquakes of magnitude 7. The building's outside structure is surrounded by perimeter columns that connect to the internal walls like floats on an outrigger boat. This creates a rigid outer shell that prevents the building from being damaged by high winds or other external forces.
The tower is built on land that was previously underwater. When water levels in the surrounding Lake Oasis rose due to climate change about 10,000 years ago, the area became susceptible to flooding. To prevent this from happening again, engineers raised the level of the lake by nearly 20 feet (6 m). They did this by digging channels for water to flow into during heavy rains, which then evaporates leaving only dry soil behind.
Because of its height, the Burj Khalifa requires special precautions against damage caused by high winds. It uses computer models to determine how strong the wind will be at different heights within the tower and then designs the structure accordingly. For example, the windscreen above hotel rooms contains strips of fiberglass attached to thin shells that can rotate if winds are strong enough. These screens can be rotated to point down any lane within the tower to direct wind away from populated areas.
The building is also equipped with rainwater collection systems.
