NS have you looked up John Hait's site on his Pahs systems of earth building. They are very simple but also advanced. Pahs stands for: Passive Annual Heat Storage (I thinK!) Something like that, but the system is designed to collect heat in the summer and radiate during the winter with no other heating required. Buildings designed this way stay at 70 degrees summer and winter.

Cheers
