COMMONLY KNOWN AS VORTICES, THESE ARE THE FORCES THAT MOVE A BUILDING FROM SIDE TO SIDE. THE SHAPE OF THE BUILDING IS VERY IMPORTANT IN THE MITIGATION OF THESE FORCES AND WE TESTED, BY WIND TUNNEL TEST, SEVERAL VARIATIONS OF THE CONCEPT UNTIL WE GOT THE ORIENTATION AND STEPPING SYSTEM TO OPTIMUM PERFORMANCE AND VERIFIED THAT THE BUILDING SHAPE RESPONDED PROPERLY TO THE MAXIMUM WINDS EXPECTED ON THE SITE.” -ADRIAN SMITH Reverse stack effect the upside down chimney With hot temperatures outside, and cold air inside, the designers were required to deal with a reverse stack effect. cold air settling inside the building would pull warm outside air in, and down through the structure. Structure don’t fall down’ ‘why buildings “The structure of the Burj Dubai is modular, with a central hexagonal shaft or core and three branches that spread out at 120 degrees from each other. Attached to these braches are wall-like columns at 9-meter spacing that simply drop off as each leg sets back, avoiding the complex and costly structural transfers.” -Adrian Smith Exterior Wall “The tower’s exterior wall is solid and reflective, shielding sunlight from its interior spaces. At the tower’s base, the fins are deeper and the glazing elements are more horizontal in proportion. The exterior skin is typical on all surfaces of the tower above the third floor until it becomes the spire, at which point the density of the verticals increases as the radius of the surfaces decreases. The primary focus of the design for the exterior wall was to eliminate any horizontal surfaces that could collect the fine-grained desert dust and sand.” -Adrian Smith SUN STUDIES FYI, DUBAI GETS A LOT OF SUN Although, apparently not a major concern, when constructing a 2600’+ tower, one does case a considerable shadow. The step backs help to mitigate this side effect. Tier layout Interior Designyou serious... ‘By Giorgio Armani, are Pretty big, eh?
