Patent ID: 8359750

Claim:
A method to fabricate a building structure, comprising: a. mixing a texture aggregate filler mixed with a phase change material (PCM), said filler being selected from the group consisting of perlite, glass microballoons, glass bubbles, phenolic microballoons, and phenolic microspheres; b. placing the PCM with the filler on a surface of the building structure exposed to a conditioned air flow and shaped to increase thermal contact between the PCM and the conditioned air flow; and c. placing elongated, open-ended, hollow PCM structures onto the surface, wherein the elongated, open-ended, hollow PCM structures are formed by first performing an extruding process to form scaffolds that have a predetermined hollow cross-sectional shape, and then coating the scaffolds with a PCM such that the PCM coats an inner and outer surface of the scaffold.
