What makes up the Dome

A geodesic Dome is an arrangement of triangles. They are efficient structures as the triangles are a very stable shape. This makes the geodesic dome buildings highly resistant to forces such as snow coverings, earthquakes, wind, and even tornadoes. The surface area of a geodesic dome is substantially less than the surface area of a box-shaped building enclosing the same floor space. There is less surface exposed to outdoor temperature fluctuations, making the building cheaper to heat and cool than a rectilinear structure. 

An advantage of the geodesic dome is that it can be constructed quickly without heavy equipment using prefabricated components. The dome supports itself without needing internal columns or interior load-bearing walls. FIG. 1 shows how the triangles are placed.
