The present analysis aimed at suggesting to model which is economically most efficient when old building's equipments of heat sources exceeded time limit. The result of study is based on field study and rear operating data of mechanic, electronic which was written by operator from 1994 to 2003. The result of study can be summarized by follows ; 1) A case 1 is same type of remodeling of equipments of heat sources for cold and hot which was installed on old building. It was calculated that initial cost is 685,952 thousand won, estimated operating cost is 659,078 thousand won by a year. 2) A case 2 is also same type of remodeling of equipments of heat sources for cold, but is not same type for hot by adapting to ice thermal storage system. It was calculated that initial cost is 958,550 thousand won, estimated operating cost is 592,682 thousand won by a year. 3) The initial cost is high in case 2. But case 2 is profitable in tax refund and supporting about equipments of heat sources. Case 2 can contribute to levelling of energy consumption, and is more economical by operating method. I think that adapting Case 2 is more economical by Case 1 form 4.11 year later.
