The technique of the present invention for minimizing the floor-to-ceiling temperature gradient of a room containing a ceiling, a floor, walls and at least one door and one window, includes the utilization of a phase change material adjacent the ceiling surface and a phase change material adjacent the floor surface. In order to effectively minimize the floor-to-ceiling temperature gradient of the room, first and second phase change materials may be either the same or different, or may be blends of phase change materials. Most preferably, the melting temperature of the first phase change material adjacent the ceiling is greater than the crystallization temperature of the second phase change material adjacent the floor. Preferably, the melting temperature of the first phase change material is 25.degree. C. plus or minus 1.degree. C. and the crystallization temperature of the second phase change material is 22.degree. C. plus or minus 1.degree. C.

[ What is claimed is:] [13.]13. A building room containing at least a ceiling surface, a floor surface, and walls, further comprising:a first phase change material having a melting temperature and fixedly positioned adjacent the surface of the ceiling; anda second phase change material having a crystallization temperature and fixedly positioned adjacent the floor surface;wherein said melting temperature of said first phase change material is higher than said crystallization temperature of said second phase change material, with said first and second phase change materials adapted to minimize a floor-to-ceiling temperature gradient established in the room.
