What is the most energy-efficient home style?
Dome-shaped homes are the most energy-efficient since they have fewer corners. This allows wind to travel over the home easily without air pressure changes, which all in all reduces air penetration and thus maintains a more even temperature. Cube-shaped homes are another good option.
