Why do geodesic 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. Efficient airflow inside that dome adds to the energy savings further; the curved surface of a dome provides a natural circulation of internal air. Outside the dome, the shape of the dome provides an aerodynamic effect; wind passes over the dome with less resistance. In comparison, a box-style structure provides a flat barrier to wind, creating positive
