Abstract

According to one embodiment, an energy consumption management system includes: a movement information creating device; a power consumption amount measuring device; an accumulating device; and a display device. The movement information creating device creates movement information regarding a person in a management target area. The power consumption amount measuring device measures a power consumption amount of an instrument in the management target area. The accumulating device creates management information in which the movement information and a power consumption amount measurement value measured are associated with each other. The display device displays the management information.

Claims

1. An energy consumption management system comprising:

a movement information creating device creating movement information regarding a person in a management target area at a predetermined time interval;

a power consumption amount measuring device measuring a power consumption amount of an instrument in the management target area at a predetermined time interval;

an accumulating device creating management information in which the movement information created by the movement information creating device is associated with a power consumption amount measurement value measured by the power consumption amount measuring device; and

a display device displaying the management information created by the accumulating device,

wherein the movement information creating device creates information regarding a number of persons present in a room as the movement information, and

the accumulating device calculates a power consumption amount per person present in the room from the acquired movement information and power consumption amount measurement value, and

the display device displays the power consumption amount per person.

2. The system according to claim 1, wherein the accumulating device acquires the movement information created by the movement information creating device and the power consumption amount measurement value measured by the power consumption amount measuring device, stores the acquired movement information and power consumption amount measurement value individually together with time information, extracts movement information corresponding to set display target period information and a power consumption amount measurement value corresponding thereto from the stored information, and creates management information in which the movement information and the power consumption amount measurement value are associated with each other at a predetermined time interval.

3. The system according to claim 2, further comprising:

means for changing the display target period information.

4. The system according to claim 1, wherein the accumulating device acquires the movement information created by the movement information creating device and the power consumption amount measurement value measured by the power consumption amount measuring device, stores the acquired movement information and power consumption amount measurement value individually together with time information, extracts movement information having position information corresponding to set display target area information and a power consumption amount measurement value corresponding thereto from the stored information, and creates management information in which the movement information and the power consumption amount measurement value are associated with each other at a predetermined time interval.

5. The system according to claim 4, further comprising:

means for changing the display target area information per instrument, per control area by the instrument, per floor in a building, per building or per region.

6. The system according to claim 1, wherein the movement information creating device further creates environment information indicating information regarding an opening degree of blinds of a window in the management target area or an opening degree of the window at a predetermined time interval, and

the display device displays the environment information.

7. The system according to claim 1, wherein the accumulating device creates the management information so as to display the management information in a table format or a graph format.

8. The system according to claim 1, wherein the accumulating device holds in advance text information with contents to urge an energy saving control operation, and contains the text information in the created management information when information contained in the management information satisfies a predetermined condition.

9. The system according to claim 1, wherein the system is connected to a control device that controls an instrument in the management target area, and

the accumulating device sends out an instrument stop instruction to stop an instrument in which the power consumption amount is larger with respect to the movement information to the control device, when it is determined to be necessary to reduce the power consumption amount.

10. An energy consumption management apparatus connectable to a movement information creating device creating movement information regarding a person in a management target area at a predetermined time interval, and to a power consumption amount measuring device measuring a power consumption amount of an instrument in the management target area at a predetermined time interval, the system comprising:

a movement information acquiring unit acquiring the movement information created by the movement information creating device when the movement information acquiring unit is connected to the movement information creating device;

a power consumption amount measurement value acquiring unit acquiring a power consumption amount measurement value measured by the power consumption amount measuring device when the power consumption mount measurement value acquiring unit is connected to the power consumption amount measuring device; and

a management information creating unit creating management information in which the movement information acquired by the movement information acquiring unit is associated with the power consumption amount measurement value measured by the power consumption amount measuring unit,

wherein the movement information acquiring unit acquires information regarding a number of persons present in a room as the movement information by the movement information creating device, and

the management information creating unit calculates a power consumption amount per person present in the room from the acquired movement information and power consumption amount measurement value.
