Passive solar wire screens for buildings

Abstract

Passive solar wire screens mount vertically on an edifice. The screens have rods vertically arranged parallel to one another and have wires horizontally arranged parallel to one another. The wires attach to the rods and have first surfaces facing away from the edifice in an upward direction from vertical. The wires also have second surfaces facing toward the edifice in a downward direction from vertical. When the sun has a summer elevation on the horizon, the first surfaces passively reflect solar energy incident thereto away from the wire screens. When the sun has a winter elevation on the horizon, however, the first surfaces passively reflect solar energy incident thereto toward the second surfaces, which in turn passively reflect the solar energy toward the edifice. A concave surface on the wires can also reflect thermal energy back to the edifice.
