- Wind tunnel tests were conducted in the schematic design stage to determine optimal shaping of the tower. [1]
- The goal: reducing wind forces to equal or below seismic loads so wind wouldn’t control the design. [1]
- Final crown configuration: high cladding porosity and open top of the crown leads to reducing wind loads in entire tower. [1]
- Curved corners and tapering shape dramatically reduce wind loads. [1]
- The building’s aerodynamic shape greatly reduces this vortex shedding by “confusing the wind”. [1]

- In response to strong winds, multi-storey wind vents are placed at strategic intervals.-These multi-story wind vents together with aerodynamic shape of the tower dramatically reduce wind loads by cutting vertex shedding.
