The purpose of this study is to understand quantitatively an optimal operation effect of a hybrid energy source system with thermal storage tank introduced into a middle scale office building. Method of Changing One Parameter at a Time is used for optimization in this paper, that is a method for calculating optimal manipulated values without curse of dimensionality. The object functions are primary energy consumption minimum, demand charge minimum and peak electrical demand minimum. The results are as follows : 1) hourly changes about the amount of heat, the electric power, the gas flow rate, the outlet water temparature and partial pump load ratio of energy source equipments differ according to the object function, 2) each optimization of energy source system enables to achieve energy conservation, running cost saving or electrical demand shifting effectively, 3) achievement degree of the optimal operation effect depends on the operating method of the energy souce equipments ( e.g. on-off or inverter operating).
