If the OK button 99c has not been clicked (step S11: NO), it is determined in step S11 whether the OK button 99c has been clicked again. That is, step S11 is repeated until the OK button 99c is clicked.
If the OK button 99c is clicked (step S11: YES), it is determined in step S12 whether there is any omission in the room name setting screen 99.
If there is an input omission in the room name setting screen 99 (step S12: NO), an error message “There is an omission of input. Please enter all room names.” Is displayed in step S13. It is determined whether the OK button 99c is clicked. That is, steps S11 to S13 are repeated until all the input fields on the room name setting screen 99 are entered.
When there is no omission in the room name setting screen 99 (step S12: YES), in step S14, all the room names input in the room name input field 99b are linked to the corresponding room numbers, and the customer information server 70 is registered in the room coordinate table 71 of the building information database 70b. Further, the floor plan of the corresponding floor displayed in the floor plan display field 95 of FIG. 7 is registered in the floor plan storage unit 73 of the customer information server 70 with the house identification number and the floor number as the file name. This step completes the registration of all the data shown in FIG. 3 for the floor being processed in the house 10 being processed.

Next, in step S15, it is determined whether or not there is an unregistered floor in the house 10 being processed for which data registration in the room coordinate table 71 has not been completed.
In this step, the room coordinate table 71 of the building information database 70b of the customer information server 70 is searched using the identification number of the house 10 being processed as a key, and all registered data of the house 10 being processed are acquired. . The number of floors of these data is compared with the total number of floors input in the ground floor input field 92 and the basement floor input field 93 in FIG. 8, and the data is input in the ground floor input field 92 and the basement floor input field 93 in FIG. It is determined whether data is registered for all floors.

If there is an unregistered floor in the house 10 being processed for which data registration of the room coordinate table 71 has not been completed (step S15: YES), the process returns to step S1 to display a CAD plan view input screen (not shown). That is, steps S1 to S15 are repeated until registration of the room coordinate table 71 is completed for all the floors of the house 10 being processed.
If there is no unregistered floor for which data registration of the room coordinate table 71 has not been completed in the house 10 being processed (step S15: NO), registration of the room coordinate table 71 has been completed for all the floors of the house 10 being processed. Then, the process of the flowchart of FIG.
Thus, the registration process of the room coordinate table 71 by the designer of the building maker 50 is completed.

Thereafter, the designer designs an electric circuit in the house 10 while listening to the intention of the owner. The designer accesses the customer information server 70 from the terminal computer 80, clicks an icon (not shown), and starts a circuit registration program.
When an icon (not shown) is clicked from the terminal computer 80, the processing of the flowchart of FIG. 9 starts. The processing in FIG. 9 is controlled by a CPU (not shown) of the customer information server 70. If the customer information server 70 is not provided, the center server 60 may perform control.

The server 60 also stores a room coordinate table 61, a circuit table 62, a plan view storage unit 63, and an elevation view storage unit 64. The center server 60 copies the room coordinate table 71, the circuit table 72, the plan view storage unit 73, and the elevation view storage unit 74 of the customer information server 70 periodically, for example, every day at midnight, and the room coordinate table 61 and the circuit table. 62, the plan view storage unit 63 and the elevation view storage unit 64 are overwritten and updated.

After the construction of the house 10 is completed, the construction manufacturer 50 gives the resident the ID and password for displaying the screen of the power usage information providing system of the present embodiment when handing over to the owner who becomes the resident. The power usage information providing system of this embodiment can be used from the display 22 of the house 10 via the home server 20. The ID and password are registered in the customer information database 70a of the customer information server 70.
When the resident enters the house 10, he turns on the main breaker 31, the branch breakers 32-1 to 32-n of the distribution board 30, the solar power generation device 40, etc. 1, the home server 20 is always connected to the Internet 1, and the power is turned on.

Thereby, the home server 20 accesses the used electric energy storage part of the storage means 37 of the distribution board 30 every predetermined time, in this embodiment every 30 minutes, and each branch breaker 32 for every predetermined time of the house 10. The data on the power consumption of the electric paths of −1 to 32 -n is acquired, registered in the power consumption data storage unit of the HDD 204, and transmitted to the center server 60.
Further, the home server 20 accesses the storage means 49 of the solar power generation device 40 every predetermined time, in this embodiment every 30 minutes, and generates electric power, electric power sales, electric power purchased every predetermined time of the house 10. Data on the power is acquired and registered in the power generation / trading power amount data storage unit of the HDD 204, and this data is transmitted to the center server 60.

An operation in which the resident of the house 10 uses the power usage information providing system of this embodiment will be described. In the present embodiment, the processing of the following power usage information providing system is controlled by the center server 60. This eliminates the need for the home server 20 to perform the processing of the power usage information providing system, reduces the processing load on the home server 20 that is often installed in the individual house 10, and facilitates maintenance and the like. . As a result, it is possible to reduce the need for maintenance and support services for the resident of the house 10 regarding the home server 20 from the building manufacturer 50 side.
