<P>PROBLEM TO BE SOLVED: To provide a thermal storage building material which gradually dissipates heat stored therein by a cooling and heating combination appliance or by using natural energy, and maintains a comfortable room temperature over a long time even if large change is generated in an ambient temperature. <P>SOLUTION: Granular solid matters each formed of a plurality of microcapsules encapsulating therein a thermal storage material are filled in an enclosing material. Preferably a mean grain size of the microcapsule is in the range of 0.5 to 100 μm and a mean grain size of the granular solid matter is in the range of 1 μm to 50 mm. Also preferably the thermal storage building material containing therein the granular solid materials each formed of the microcapsules encapsulating therein a thermal storage material having a melting point of 5 to 40°C is for use as an inner finish building material, and the thermal storage building material containing therein the granular solid materials each formed of the microcapsules encapsulating therein a thermal storage material having a melting point of 20 to 60°C is for use as a floor heating thermal storage material. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
