Triangular Shape
Advantage: wind accelerates at the corner Disadvantage: wind may not flow along straight edge and the bounce-back can cause downdraft which is dangerous for ground level pedestrians.
Cylindrical Shape
Advantage: wind flows along curvy edge from all directions. Disadvantage: wind may not be easily controlled at a high altitude, and distribute a great amount of pressure for the building envelope.
Geometry Integration Wind flow tests on two fundamental geometries.
Concept Development and Evolution
Potential Problems The size of the core will not be able to vertically transport people. Elevators facing different directions is not energyefficient. The set-back/rotation of every two floor is too much. Even though it offers extra room to place wind turbine, but still it is a waste of space.
The size of the core is increased, but still elevators are facing opposite directions, thus people will not see the elevators coming on the other side. No room to install the wind turbines. Cantilevered structure will add more weights for the floor slabs. Corners are too pointy.
Wind turbines can be placed on the floor slabs, but the straight/ sharp corners of curtain wall will stop the wind continue to flow.

Note: Wind flows from left to right (Or lower left corner to the upper right corner in perspective views). Conditions are the same in all testing.
Design Investigation Using simulation flow to examine/test the ideal form
opening for natural ventilation when wind flows paralleling to structure
opening for natural ventilation when wind flows diagonally to structure
Computational fluid dynamics analysis on selected form and further development
