The demand pattern with a high time resolution is indispensable to examine and design an appropriate distributed energy system for residential sector. This paper describes energy consumption pattern with high resolution in the apartment of a cold district which consists of 34 households. The heat-power ratio of energy demand changes from about two in summer to about ten in winter. The maximum electric power demand is about IkW/household and the minimum is about 200W/household. The estimated minimum capacity of electricity storage device is 80wh/household. The several simulation of distributed systems based on the survey of energy demand is carried out. By the system which consists of SOFC and heat pump, as a result of operating heat pump in accordance with heat demand, energy consumption was reducible 26%. Further, as a result of enlarging the generator of the system and operated to meet electric power and heat demand, energy consumption was cut down further and 95% of total electric power demand has been supplied by the distributed system. Furthermore, in the system which added the electricity storage device of the capacity of 10kWh, it turns out that it is possible to supply 100% of electricity demand.
