PROBLEM TO BE SOLVED: To provide an information processing unit, an information processing method, and an information processing system by which an electric company can calculate power consumption by lighting apparatuses separately from power consumption by other electric appliances, without using questionnaire survey.SOLUTION: An information processing unit has a memory and a processor. The processor acquires time series information about power consumption of each of a plurality of rooms to store the information in the memory, and in a case where the time series information of the power consumption stored in the memory indicates that, before power consumption of a first room out of the plurality of rooms changes from a low level to a high level, power consumption of a second room which is different from the first room out of the plurality of rooms changes from a high level to a low level, the processor determines that the change in the power consumption of the first room and the change in the power consumption of the second room are caused by lighting apparatuses. |
