How can you run your home freely like a sailing ship for best thermal performance in the Australian climate? An earth home could be the answer.
The analogy of a ship is apt, because as with sailing there is no engine, or in the case of and earth home, no air conditioner.
My own earth home is not conditioned; it is naturally conditioned through mass-linked ventilation so the whole operation is passive, silent and free and allows for passive cooling comfort all summer.
On a sailing boat you work the rudder and sails to travel about freely. You run, reach or work to achieve this. It's impossible to say you will achieve a set distance, speed or time of arrival or departure, but sailing is a healthy, rewarding, exciting experience and on average it works very well.
