Abstract
Abstract A wall system having an internal mass for inwardly radiating retained heat, an insulation layer and an external heat-conductive skin spaced apart from the insulation layer for permitting the external environment to influence the air space conditions. The air space becomes the external environment to the insulation layer, rather than an exterior mass as with conventional wall systems, thereby reducing the load for the internally operating air conditioning and heating system. The air space is vented top and bottom so as to allow convection currents of accumulated hot air in the space to be created, thereby not only isolating the external environment from the air space but minimizing extremely hot air accumulation of air and when desired increasing the temperature in the air space above environmental conditions for enhancing the efficiency of the internally operating air conditioning and heating systems.
