The aluminium framework of the structure has an igloo shape. The supporting has three joints, so it can be closed to a very small size. The closed shape which is similar to a shell makes possible to “throw it to the ground” with a parachute safely. The phases of the assembly can be seen in the middle row of graphs.
The igloo shape of the open structure can resist to the wind effect, and the least specific surface belongs to this capacity (cooling down surface) that’s why this building form has spread through the cool climate areas for thousand years)
The heat insulation canvas goes to the standing structure. (It goes also to the flooring) #Greenland
