Each panel is a sandwich of two glass sheets Dubai’s climate is both hot and very moist, averaging 90 percent humidity and sometimes with a small air gap between them. The outer sheet can withstand high surface temperatures reaching 98 percent. 3 The and is covered in a special coating that prevents contrast between this warm, wet light and solar heat from penetrating the air and the cool interior of the building. The coating cannot block the infrared building leads to condensation, energy that radiates back from the hot desert which can discolor the Burj’s cladding.
These walls mimic beams, providing horizontal resistance to the downward load exerted by gravity. Spaced along the height of the building, there are also five three-story groups of floors used for mechanical and maintenance purposes. From these, deep outrigger walls extend from the central core around the perimeter of the wings. The horizontal outriggers connect to vertical columns. This transfers lateral loads from the walls to the columns, which then channel them down to the foundation. The advantage of this system is increased efficiency.
