Abstract
The invention comprises means of controlling the insolation and radiation of passive solar thermal storage columns for heating and cooling of homes and other structures. In one embodiment rotatable insulating panels control the exposure of round thermal storage columns to daytime sunlight and the nighttime sky. A second embodiment allows independent rotation of the column and the insulation panel for further control of the insolation and radiation. In a third embodiment the rotatable insulating panels are positioned in concave depressions formed in vertical thermal storage columns. These columns include individual thermal convection means formed therein and are particularly suited to precast concrete or masonry construction. In a fourth embodiment the rotatable panels are adapted to retrofit existing masonry walls for passive solar thermal storage. The constructions disclosed can be utilized for vertical walls, sloping walls and roofs and flat roofs. Structural support must be modified depending on the orientation, however, the basic modes of operation are suitable for all orientations.
