Patent ID: 6879884

Claim:
An energy evaluation support system for presenting an amount of energy consumed in a factory with a plurality of devices to a user, the devices including a plurality of production devices and a plurality of requisite-power supply devices which supplies a plurality of types of requisite power to the plurality of the production devices, the system comprising: receiving means for receiving a design request of a factory including a production condition instruction indicating a production condition decided by the user; storage means for storing a production device database containing data relating to the plurality of the production devices and a requisite-power supply device database containing data relating to the plurality of the requisite-power supply devices; processing means for computing an amount of first energy consumption for each of the plurality of the production devices and the plurality of the requisite-power supply devices and for each type of the requisite power, based on the production device database and the requisite-power supply device database according to the design request; and output means for presenting the amount of the first energy consumption computed by the processing means to the user in a predetermined form, wherein the processing means: selects production devices to be used among the plurality of the production devices according to the production condition instruction, and computes an amount of the requisite power required by the production devices to be used for each type of the requisite power; selects requisite-power supply devices to be used among the plurality of the requisite-power supply devices, based on the amount of the requisite power for each type of the requisite power, and computes an amount of second energy consumption required by the requisite-power supply devices to be used for each type of the requisite power; and computes a coefficient of energy consumption indicating an amount of third energy consumption per predetermined unit of the requisite power supplied by the requisite-power supply devices to be used, based on the amount of the second energy consumption for each type of the requisite power, and computes the amount of the first energy consumption based on the coefficient of energy consumption.
