In Phase 1, the parametric model for One WTC was imported into Revit. The maximum allowable height was 755’ and the maximum tower base was 233’. Floor to floor height was set at 12’.
The tower base was held constant throughout testing. The parameter being adjusted was defined and set to vary between 601’ and 746’ in increments of 29’. A custom node was used to run the resulting 6 cases. The result was reported on excel.
This design was inspired by a pencil. First I created a hexagon shaped mass family. Then I imported the template for a twisting tower and replaced the family with the hexagons. After that, I assigned the width and the depth of the hexagons and then saved the tower as a template. This template model was then imported and the floors were assigned. Then I set the base and the midpoint depth and width to be 271’ and tapered the tower from the mid-point onwards. The top diameter is 30’. The parameter used to flex is the height of the tower. In order to retain the pencil inspired design of the building, rotations between the base, midpoint and top have been kept relatively low.
The lowest height is around 515’ and the highest is around 755’
Points to Ponder → Exporting values to excel allows for easy manipulation of number for conducting feasibility studies and other analysis that might be required for design decisions. It also allows for easy sharing between technical and non-technical teams since Excel is more universal than Revit.
