Shanghai Tower: performance-based design

At 128 stories, the Shanghai Tower, which was completed in September 2015, is the tallest building in China and the second tallest building in the world.  The design criteria included an aggressive sustainability agenda to achieve a LEED (Leadership in Energy and Environmental Design) Gold rating, the second highest rating in LEED's benchmarks for high performance green buildings--very impressive for a building that's over 4 million square feet!

From its inception, Gensler turned to building information modeling (BIM) software for performance-based design to measure their plans against performance objectives.  Gensler used simulation software to better understand the skyscraper's response to typhoons and engineer the structur of the building to respond to these forces.  Iterative wind simulation helped the design team understand the relationship of building form to structural engineering requirements.  The resulting twisted shape of the building not only reduces wind loads, but also reduced the structural engineering systems and material costs of the project by $58 million!
