The evaluation metrics were used to compare how different rotation angles affected the overall building form and performance. Metrics such as building volume, surface area, and overall geometric stability helped identify which angles created the most balanced and visually effective design.

Point to Ponder: Exporting the values to Excel makes it easier to organize, compare, and graph large sets of parametric data. It also allows designers to quickly identify trends, evaluate performance differences between iterations, and create clearer visual presentations of the results.

The design is a parametric twisting tower generated by stacking and rotating floor profiles vertically to create a dynamic high-rise form. Key parameters such as floor count, floor height, twist angle, and scale factor can be adjusted to flexibly control the tower’s height, amount of rotation, tapering, and overall building proportions.

The twist angle had the biggest effect on the building form because even small changes quickly changed the overall silhouette. The scale factor was also important because it controlled whether the tower looked straight, tapered, or more sculptural.
