Thanks for the information! The Wofati houses are an interesting alternative. However, do you know how feasible it would be to construct one in very rough, rocky terrain--like the deserts of Colorado? Also, you're saying if I do choose to use wood for the roofing material, ensure it shares the same air as the inside of the house? And this will prevent molding and rotting of the wood? And one further question: for passive solar homes, insulation should be placed only (including around windows and door frames) on the outside of whatever material is high in thermal mass, correct? So, for instance, if the walls of the structure are earth-rammed tries, I should apply only a water membrane and plaster coating to the inside, but wrap the outside with insulation. Or does this depend entirely on my climate conditions? If it is a hotter climate, will I need less insulation? Now I am confusing myself. Please, clarify.
