## Abstract

An energy event recording apparatus is mounted on each of a plurality of equipment installed at a business facility. When a change in the amount of the flow or stock of energy is detected in the apparatus mounted, each of a plurality of the energy event recording apparatuses records journal information, which associates the amount of change to a debit side item and a credit side item, respectively, and notifies an energy management server of the journal information. The energy management server calculates pieces of journal information conveyed from a plurality of recording apparatuses, respectively, based on the debit side item and the credit side item.

## Claims

### Claim 1

An energy management server for use with a device to be monitored comprising an energy meter, the device to be monitored being configured to output energy event described in a form of exchange algebra occurring in the device to be monitored the energy event being a change in a flow or a stock of energy of the device to be monitored as measured by the energy meter, the energy management server comprising:
a communication interface configured to receive energy event described in a form of exchange algebra output by the device to be monitored;
storage configured to store, as a plurality of algebraic data objects, the energy events described in a form of exchange algebra in an energy bookkeeping description including the first term items of exchange algebra describing energy events and a second term items of exchange algebra describing energy events;
a counting processor configured to, after a predetermined period of time, generate energy accounting data conforming to the energy bookkeeping description by aggregating the energy event described in a form of exchange algebra stored in the storage, based on the first term of exchange algebra describing energy event and the second term of exchange algebra describing energy event;
a display for displaying the energy accounting data generated by the counting processor; wherein
the counting processor is configured to perform a transfer process on a result of aggregation by using exchange algebra, and generates the energy accounting data.

### Claim 2 (depends on 1)

The energy management server according to claim 1, wherein the counting processor generates an energy balance sheet for a current term, in accordance with the energy balance sheet for a previous term related to a flow or stock of energy in said one or a plurality of devices to be monitored and with an energy profit-and-loss statement for the current term, the energy balance sheet for a previous term being the energy accounting data recorded in the previous term, and an energy profit-and-loss statement for the current term being generated by the energy accounting data for the current term.

### Claim 3

An energy management method for managing energy balance of a device to be monitored, the device to be monitored being configured to output energy event described in a form of exchange algebra relating to an energy event occurring in the device to be monitored the energy event being a change in a flow or a stock of energy of the device to be monitored as measured by the energy meter, the method comprising:
receiving energy event described in a form of exchange algebra output by the device to be monitored via a communication interface;
storing, as a plurality of algebraic data objects, the energy event described in a form of exchange algebra in an energy bookkeeping description including first term items of exchange algebra describing energy events and a second term items of exchange algebra describing energy events;
recording, with a counting processor after a predetermined period of time, energy accounting data conforming to the energy bookkeeping description by aggregating the energy event described in a form of exchange algebra, based on the first term of exchange algebra describing energy event item and the second term of exchange algebra describing energy event item; and
displaying the recorded energy accounting data to a display;
wherein the counting processor aggregates a plurality of pieces of energy event described in a form of exchange algebra in units of each energy, performs a transfer process on a result of aggregation by using exchange algebra, and generates the energy accounting data based on a result of the transfer process.

### Claim 4 (depends on 1)

The energy management server according to claim 1, wherein the counting processor aggregates based on a basis in units of energy, converts a result of aggregation into a unit of money amount by referencing a predetermined conversion rule, and generates the energy accounting data base on a result of conversion.
