Abstract

[Object] To correct a power consumption record in a period in which energy-saving control is performed and a power consumption record in a period in which the energy-saving control is not performed in accordance with a purpose of the comparison, and to enable evaluation of power consumption from various viewpoints. [Solution] A terminal device configured to evaluate power consumption of equipment includes a communication control unit configured to acquire a power consumption record of the equipment, and a processing unit configured to output data related to power consumption records before and after an energy-saving operation of the equipment. The processing unit performs correction I and correction II (II′) to make one of a power consumption period in an operation period before the energy-saving operation and a power consumption record in an operation period after the energy-saving operation comparable with the power consumption record in the other operation period, and then outputs data related to the power consumption records before and after the energy-saving operation.
