Part 1: Rounded Triangular Twisting Building Form
I started off by defining a few constraints within the instance parameters for the given triangular twisting tower. For this design, I wanted to flex the Bottom Radius parameter. Since the goal is to minimizing costs (lowering SF as we get higher), I wanted to reduce the Top Radius as the Bottom Radius got larger, placing more of the required gross floor area closer to the base of the structure. This was done by setting up a multiplier that would result in a smaller Top Radius as the Bottom Radius got larger (I assume the Base Radius will not exceed 200 ft as we also have a limit on footprint size).
Instance Parameters and Constriants:
Within my dynamo script, I test Base Radius values from 150 to 180 ft, incrementing every 6 ft. For the results collected, I modified the custom node to return an additional Gross Volume metric as well as a collated list for all three metrics being evaluated (gross floor area, gross surface area, and gross volume). This was then returned by the script and written into an excel file. The results of the parametric study can be found below.

Part 2: Rounded Rectangular Twisting and Tapered Building Form
For my second form, I decided to make a rounded twisting and tapering rectangular form. The idea for this was to create a base half that would be twisted and for the top half tapered (manually setting Top Rotation and Mid Rotation to be equal and Base and Mid Rotation to be 45 degrees off in the Revit file). For this study, I will be flexing both the Top Side 1 parameter and the Top Height parameter.
Within my dynamo script, I test Top Height values from 550 to 650, incrementing every 25 ft, and Top Side 1 from 80 to 90, incrementing every 5 ft. Since this is a multivariable study, the two parameters are laced together to create a total of 15 tested forms. For the results collected, I modified the custom node to return an additional Gross Volume metric as well as a collated list for all three metrics being evaluated (gross floor area, gross surface area, and gross volume). This was then returned by the script and written into an excel file. The results of the parametric study can be found below.
