Why do dome structures conserve energy for heating and cooling?
The answer again lies in the shape of the geodesic structure. The lower the total outside surface area (walls and ceilings) the greater the efficiency in energy use for heating and cooling. A dome has approximately one-third less surface area to the outside than a box-style structure. The amount surface area exposed to the elements has a much greater impact on energy efficiency than insulation values. Additionally, heat loss from the foundation of a home is generally more dependent on perimeter length than floor area. A dome, having a smaller perimeter/square footage ratio than a box-style home, will lose less heat from the foundation. The number one factor affecting the efficient use of materials and energy in any structure is its shape. Many of today’s contemporary homes, with vaulted ceilings are the least efficient homes technically possible. By contrast, a typical 1500+ sq. ft. geodesic dome home, with a 23′ ceiling height in the living room actually uses almost 20% less material
