This paper presents the optimal plan in an assumption co-generation system based on Advanced Co-generation system built on Kikui-cho campus and suggest the introductory technique of co-generation system. At first, we analyzed the change in a year of the electric power and cooling demand in a typical consumer and completed the assumption model by formulizing. In the hospital, the hotel, etc., it was checked that electric power and cooling demand have the high correlation with outside temperature, and the maximum temperature in one day is effective as an explanation variable especially. We verified about the optimal planning according to the consumer using this assumption demand.
