DOME GEOMETRY: Frequency is the number of intersections from the center of one pentagon grouping to the next pentagon grouping.

  • Ai's 22’ and 27' domes are 2-frequency, 1/2 spheres on a 4' vertical riser.
  • Ai's 30’, 34’, 36', 40’, 45’, and 48' domes are 3-frequency, 3/8 spheres on a 4' vertical riser.

American Ingenuity's 30' through 48' in diameter domes are approximately a one half sphere with a four foot tall riser wall. 

5/8 Domes:

  • Ai. finds it more practical to use a vertical 4' riser wall on all of its domes instead of designing its domes with the 5/8 geometry.
  • Ai's 30' dome turns out to be almost the same height as a 5/8 dome.
  • Also the 4' riser wall makes for a better shaped entryway and allows the dome to link with all of our other size domes.
