PART 1:
I used the Parametric Tower – Twisting Rounded Triangular Mass for Part 1 of this assignment.
First, I placed the tower in Revit, and then I set the Project Location to 200 Folsom Street in San Francisco. The sun path is set to 1-day solar study.
I decided to only change the top rotation of the tower and keep other parameters constant, as listed below. The building height is at its limit (because I wanted the building to be as tall as possible to ensure a good view), 750 ft, and the base radius is 150 ft, the building footprint in plan view is well within the 300’ x 450’ limit. I will worry about the cost and other factors in the next module.
In Dynamo, I selected the tower in Revit. I set up two parameters to adjust their values, and I also prepared the parameters’ names to obtain the gross floor area, gross surface area, and gross volume values. The top rotation will be increased from 30 to 85 degrees, with a 5-degree increment. Since part 1 only asked us to change one input, I kept the second parameter, Mid Radius, constant.
By using the Cartesian product, I could combine the two parameters and create input pairs.
I modified the BuildingForm.EvaluatePairsOfInputsAndReportMultipleResults custom node provided in class, so it can now also output the gross volume values.
I used the List.Map to loop the list of inputs and report the corresponding results. Then, I exported the results (parameter 1, parameter 2, gross floor area, gross surface area, gross volume) to Excel.
Part 1’s result table: The gross floor area of all options falls between 1200000 SF and 1500000 SF as required.
PART 2:
For the second part of the assignment, I created a quatrefoil profile because I personally really like this shape and I loaded the profile into the 3-point twisting tower template. The profile’s width and depth are adjustable parameters. I also set the material of the tower as a parameter. I was able to change the tower’s tower to yellow to make it more bright and vivid.
The procedure is the same as in part 1.
I decided to only change the mid rotation and mid width of the tower and keep other parameters constant, as listed below. I kept the top and base rotation to be 0 because I wanted the twisting of the tower to be controlled by the mid rotation. The building height is at its limit, 750 ft, and the base radius is 150 ft, the building footprint in plan view is within the 300’ x 450’ limit.
The mid rotation changed from 100 to 120 degrees, with a 10-degree increment. The mid width changed from 105 to 125 degrees, with a 5-degree increment. By using the Dynamo logic created in Part 1, my results are listed below. The gross floor area of all options falls between 1200000 SF and 1500000 SF as required.
I will analyze the building in the next module.
