Claim 11:
12. An opaque building structure, comprising:
framing; and
an exterior sheathing attached to the framing, the exterior sheathing having an exterior inner surface;
an interior wallboard attached to the framing, the interior wallboard having an interior inner surface;
between the space formed by the framing, the exterior inner surface, and the interior inner surface:
a tandem series of highly reflective insulation elements attached to the framing, comprising:
a first highly reflective insulation element comprising:
a first pair of parallel surfaces forming in part a first air space of still air, the first pair of parallel surfaces including the exterior inner surface and a first heat energy highly reflective surface and parallel with the exterior inner surface and the interior inner surface, and
a first material insulation element having a first face supporting the first heat energy highly reflective surface; and

a second highly reflective insulation element comprising:
a second pair of parallel surfaces forming in part a second air space of still air, the second pair of parallel surfaces including a second heat energy highly reflective surface and a third heat energy highly reflective surface, and parallel with the exterior inner surface and the interior inner surface; and
a second material insulation element having a first face supporting the third heat energy highly reflective surface; and

wherein the first material insulation element has a second face supporting the second heat energy highly reflective surface.
