Passive temperature regulation system for building cooling. Water-filled plastic containers are integrally molded directly onto the metal roof, eliminating the separate support frameworks required by earlier designs. The uneven lower surface of the roof section (channels/protrusions) mechanically locks the rotationally molded plastic during manufacturing. At night, the water radiates heat to the sky; daytime insulation prevents heat gain.
A temperature regulator: thermally conductive planar roof element with uneven lower surface; a rotationally molded plastic container integrally bonded to that surface; water-filled interior chamber; insulation with vertical passages enabling water circulation.
Two-part mold with removable lower portion attached to a metal roof section. Melted plastic is rotationally molded within the assembly, conforming to channels and adhering permanently. Lower mold removes after cooling; plastic remains mechanically locked to roof.
