<P>PROBLEM TO BE SOLVED: To provide an energy monitoring system that accurately calculates an energy consumption amount regardless of the presence of energy generation by energy generating equipment. <P>SOLUTION: The energy monitoring system includes a generation amount measuring means for measuring a generation amount of energy generated by the equipment for generating energy deliverable from a building, a supply amount measuring means for measuring a supply amount of energy supplied to a building, a delivery amount measuring means for measuring a delivery amount by using energy flowing in a direction opposite to the energy supplied to a building as delivery energy from a building, and a consumption amount calculation means for calculating an energy consumption amount on the basis of the measured values of the measuring means. The consumption amount calculation means includes a decision means for determining the presence of the measurement executed by the generation amount measuring means, and a consumption amount specifying means that calculates an energy consumption amount in a specific period on the basis of each integrated value of the measured values when determined that the measurement is executed and approves the integrated value of the supply amount measured values as the energy consumption amount in the specific period when determined that the measurement is not executed. <P>COPYRIGHT: (C)2010,JPO&INPIT |
