This note reveals why geodesic domes are efficient for enclosing space, highlighting material use and surface area.
This note shows why geodesic domes are the most efficient buildable way to enclose space. They approximate the sphere—the shape with the least surface for a given volume—using rigid triangular panels you can actually fabricate. As subdivision increases, material use approaches the theoretical minimum and member strength scales favorably.
