My question is: Why do we not see more building recommendations along this line of thinking? Various experimental aspects of this structural approach (to managing HVAC with zero-energy input) have been proven effective, in recent decades. Some ancient architecture also demonstrates the effectiveness of the approach. Present day oversight might primarily be induced by subconscious avoidance of anything which seems to relate to cavemen. (Some cavemen may have somewhat understood annualized heat). Yet today we have so many aspects which should delight an architect while incorporating elements of like design. While incorporating such features in houses which appear ordinary might increase costs of a project, could one not suppose that "free energy" is incentive enough, to try some features-- I have studied various approaches to this -- My extended blogs with many web links--
