Abstract: An energy management device includes: an acquirer that acquires a reduction target period, a reduction target amount, an equipment type, a presence of a special operation schedule, a scheduled time of a special operation, and a status; a generator that generates multiple control patterns on the basis of the information acquired by the acquirer; a selector that selects a control pattern to execute from among the multiple control patterns; and a controller that transmits control information to the equipment to be controlled on the basis of the control pattern to execute. At least one of the multiple control patterns is a control pattern for shifting the scheduled time of a special operation to outside the reduction target period, and reducing the power consumption amount by the reduction target amount or more during the reduction target period.

Abstract: In a communication system in which a terminal 1 connected to an internal network 5 communicates with an external network 9 through a control device 2 which controls communication, the control device 2 includes an address registration unit 33 which registers a pair of an address of the terminal 1 and an ID, a storage unit 21 which stores a filtering rule that defines a condition to permit or deny the communication of the terminal 1, and a filter unit 22 which determines whether communication of a packet should be permitted or denied, based on a result of comparison between information stored in an address storage area of the packet transmitted from the terminal, and the filtering rule, when the registered ID is contained in the address storage area of the packet, thereby controlling communication of the pack.
