To explain in detail, the calculation execution unit 15 assumes that the energy consumption at the time of introducing the cheapest equipment calculated in the above calculation L2 is entirely covered by the power generation of the solar panel, and the required power generation capacity of the solar panel. Is calculated. At this time, the calculation execution unit 15 calculates the required power generation capacity based on the area characteristic information acquired by the area characteristic information acquisition unit 11, particularly the shape, slope, and orientation of the roof. In this embodiment, as shown in FIG. 6, the required power generation capacity is calculated for each direction. Strictly speaking, it is said that the power generation capacity will be secured preferentially from the direction in which the amount of power generation increases, and when the maximum load limit of the solar panel is reached in that direction, the power generation capacity will be secured in the next direction. Calculate the required power generation capacity for each direction according to the procedure.

The condition storage unit 16 stores the proposed conditions set for the ZEH realization device group. The proposed condition is a condition to be satisfied by the ZEH realization equipment group (combination of energy-related equipment) to be proposed. In the present embodiment, the condition storage unit 16 stores a plurality of proposed conditions, specifically, the first proposed condition, the second proposed condition, and the third proposed condition.

To outline each of the proposed conditions, the first proposed condition is a standard condition for achieving ZEH. Specifically, the primary energy consumption when each device related to the ZEH realization device group is used in a house. It is a condition that (hereinafter, the set primary energy consumption) is suppressed to the amount achieved by ZEH or less. Here, the ZEH achievement amount is a value obtained based on the reference primary energy consumption calculated by the calculation execution unit 15 and the preset reduction rate, and specifically corresponds to the reduction rate. It is the amount obtained by subtracting the amount from the standard primary energy consumption. Since the reduction rate is set to 20% in this embodiment, the amount of ZEH achieved is equivalent to 80% of the standard primary energy consumption.

The second proposed condition is a condition that prioritizes cost performance. Specifically, when there is a device that is more advantageous in terms of cost performance than adopting a solar panel, the device is used instead of the solar panel. It is a condition to introduce. In other words, under the second proposal condition, when there is a device that is cheaper than the installation cost of the solar panel and can be expected to save more power (or generate more power) than the power generation capacity of the solar panel. , The device will be added to the ZEH realization device group.

The third proposed condition is a condition that prioritizes the energy saving effect. Specifically, the energy saving effect is maximized within the amount indicated by the budget information acquired by the budget information acquisition unit 12 (that is, the budget amount). It is a condition. In other words, the third proposed condition is to maximize the energy saving effect obtained while keeping the total introduction cost of the equipment in the ZEH realization equipment group below the budget amount. Therefore, under the third proposal condition, if there is a device with a higher energy saving effect, the device will be added to the ZEH realization device group as long as the total amount of the device introduction cost is within the budget amount. ..

The condition designation unit 17 causes the user to specify a desired condition from the three proposed conditions stored in the condition storage unit 16, and accepts the designation result. More specifically, the condition designation unit 17 displays three proposed conditions with radio buttons on the input screen (strictly speaking, the area marked with the symbol P4 in the figure) shown in FIG. The user specifies a desired proposal condition among the three proposal conditions displayed on the above input screen, and checks the radio button attached to the condition. The condition designation unit 17 acquires the user's designation result for the proposed condition through such an input operation. The number of proposed conditions that can be specified at one time may be one or a plurality (two or three).

The device identification unit 18 identifies a group of ZEH realization devices that satisfy the proposed conditions specified by the user. Further, the device identification unit 18 specifies the ZEH realization device group based on the result of the calculation by the calculation execution unit 15. Specifically, the device identification unit 18 describes each value calculated by the calculation execution unit 15, strictly speaking, the standard primary energy consumption in the house, the energy consumption at the time of introducing the cheapest device, and the required solar power. The ZEH realization equipment group is specified based on the power generation capacity of the panel. The procedure for specifying the ZEH realization device group will be described in a later section.

The output unit 19 executes a process for outputting the ZEH realization device group specified by the device identification unit 18. Specifically, the output unit 19 generates data on the output screen indicating the ZEH realization device group and develops the data. As a result, the output screen shown in FIG. 2 in which the ZEH realization device group is displayed is drawn on the display of the present device 1.

Further, in the present embodiment, as shown in the figure, in addition to the ZEH realization device group, the primary energy consumption when each device related to the ZEH realization device group is used in a house (that is, the set primary energy consumption). , The introduction cost of the ZEH realization device group is also displayed on the output screen. In other words, when generating the data on the output screen, the output unit 19 generates the above data so that the set primary energy consumption and the device introduction cost are displayed on the output screen.

In the present embodiment, the specific result of the ZEH realization device group is output through the output screen drawn on the display of the present device 1, but the present invention is not limited to this. For example, the specific result may be output by printing an image (character image) showing the specific result of the ZEH realization device group with a printer.

<< About the device proposal method according to this embodiment >>
Next, a device proposal method using the present device 1, and for easy understanding, a method of proposing a ZEH realization device group will be described. Such a method corresponds to the device proposal method of the present invention, and is realized by the device proposal flow described below. That is, in the following device proposal flow, the device proposal method of the present invention is adopted, and each step in the device proposal flow corresponds to a component of the device proposal method of the present invention.

Hereinafter, the flow of the device proposal flow will be described in detail with reference to FIGS. 7 to 10. FIG. 7 is a diagram showing the flow of the device proposal flow. FIG. 8 is a diagram showing a procedure of a device specifying process (hereinafter, first device specifying process) when the first proposed condition is specified. FIG. 9 is a diagram showing a procedure of a device specifying process (hereinafter referred to as a second device specifying process) when the second proposed condition is specified. FIG. 10 is a diagram showing a procedure of a device specifying process (hereinafter, a third device specifying process) when the third proposed condition is specified.

The device proposal flow is carried out by the employee's personal computer (computer) that constitutes the device 1, and specifically, an operation performed by the employee to start the device proposal program (for example, clicking the icon of the device proposal program). Operation) will be the trigger. In the device proposal flow, first, the input screen shown in FIG. 1 is drawn on the display of the personal computer (S001). On this input screen, a plurality of candidates set as prerequisites for using energy-related equipment in a house are displayed in a selectable state.

That is, in step S001, the input screen is drawn on the display, so that the precondition candidates are presented to the employee. In this sense, it can be said that this step S001 corresponds to the precondition presentation step. On the input screen, a plurality of proposed conditions set for the ZEH realization device group are displayed in a selectable state.

Next, the employee inputs necessary items through the above input screen. The employee's personal computer accepts the input (S002). As a result, the above-mentioned personal computer will acquire the housing identification information, the budget information, the selection result of the employee for the candidate for the precondition, and the designation result of the employee for the proposal condition. As described above, in this step S002, the input operation is performed through the input screen, so that the above-mentioned personal computer accepts the selection result of the employee for the candidate for the precondition. In this sense, it can be said that this step S002 corresponds to the selection result reception process.

After the input is completed, when the employee performs a predetermined operation (for example, an operation of clicking the proposal execution button B in the input screen shown in FIG. 1), the employee's personal computer accesses the database server 2 with this as a trigger. .. Then, the personal computer reads and downloads (acquires) the information associated with the house identification information acquired in the previous step S002 from the area identification information stored in the database server 2 (S003). After that, the above-mentioned personal computer sequentially executes the above-mentioned operations L1, L2, and L3 based on the information acquired in steps S002 and S003 (S004 to S006). It should be noted that these steps S004 to S006 correspond to the calculation execution process.

Specifically, the above-mentioned personal computer calculates (estimates) the standard primary energy consumption in the house that the prospective house purchaser is considering purchasing (S004). At this time, the personal computer calculates based on the area identification information acquired in step S003 and the selection result of the employee for the precondition candidate acquired in step S002.

In addition, the above-mentioned personal computer calculates the primary energy consumption at the time of introducing the cheapest device (S005). Specifically, the device specifications of the energy-related equipment to be used in the house are determined based on the area identification information acquired in step S003 and the selection result of the employee for the precondition candidates acquired in step S002. .. Then, the personal computer accesses the database server 2 and reads out the information of the cheapest device that satisfies the above device specifications from the device information stored in the server. After that, the personal computer calculates the primary energy consumption at the time of introducing the cheapest device based on the device information of the cheapest device read out. Also in this case, the primary energy consumption is calculated according to the selection result of the employee with respect to the candidate of the precondition acquired in step S002, that is, the content of the candidate of the precondition selected by the employee.

Further, the above-mentioned personal computer calculates the capacity of the solar panel required to cover all the energy consumption at the time of introducing the cheapest device calculated in the previous step S005 (S006). At this time, the personal computer calculates the required power generation capacity for each direction based on the area characteristic information acquired in step S003.

After completing the above calculations, the employee's personal computer identifies the ZEH realization device group based on the calculation results in each step (specifically, S004 to S006). Specifically, the above-mentioned personal computer specifies the proposal condition specified by the employee when specifying the ZEH realization device group, and specifies the ZEH realization device group that satisfies the proposal condition. More specifically, when the employee specifies the first proposal condition (Yes in S007), the employee's personal computer carries out the first device identification process as the device identification process and satisfies the first proposal condition. A group of ZEH realization devices is specified (S008).

Explaining the flow of the first device specifying process with reference to FIG. 8, first, the combination of the cheapest devices selected in step 005 is tentatively set as the ZEH realization device group (S021). Next, the primary energy consumption at the time of introducing the cheapest device, which is also calculated in step S005, is specified (S022). Then, it is determined whether or not the specified primary energy consumption is less than the ZEH achievement amount (that is, the amount corresponding to 80% of the standard primary energy consumption) (S023). Then, when it is determined that the primary energy consumption is less than the amount achieved by ZEH, the combination of the cheapest devices is specified as the ZEH realization device group, and the ZEH realization device group is determined by this (S025).

On the other hand, if it is determined that the primary energy consumption specified in step S022 is not less than the ZEH achievement amount, it is more cost effective than the cheapest energy-related device whose device information is registered in the database server 2. Select a device with a large value and replace the device with the cheapest device (S024). At this time, it is preferable to preferentially select the device having the highest cost effectiveness. Then, step S024 is repeated until the primary energy consumption after the device replacement falls below the ZEH achieved amount. Finally, the combination of devices when the primary energy consumption falls below the ZEH achieved amount is specified as the ZEH realization device group, and the ZEH realization device group is determined by this (S025).

Returning to the explanation of the device proposal flow, when the employee specifies the second proposal condition (Yes in S009), the employee's personal computer carries out the second device identification process as the device identification process, and the second A group of ZEH realization devices satisfying the proposed conditions is specified (S010).

Explaining the flow of the second device specifying process with reference to FIG. 9, first, the combination of the cheapest devices selected in step 005 is tentatively set as the ZEH realization device group (S031). Next, among the energy-related devices whose device information is registered in the database server 2, the purchase price is cheaper than the installation cost of the solar panel, and the power saving amount (or power generation) is larger than the power generation capacity of the solar panel. It is determined whether or not there is a device for which the amount) can be expected (S032). Then, when it is determined that there is no device that meets the above requirements, the combination of the cheapest devices is specified as the ZEH realization device group, and the ZEH realization device group is determined by this (S034).

On the other hand, when it is determined that the corresponding device exists, the device and the solar panel are replaced (S033). Strictly speaking, the solar panel with the capacity corresponding to the power saving amount (or power generation amount) of the corresponding device is replaced with the above-mentioned corresponding device. If there are a plurality of applicable devices, step S0033 is repeated for the number of the devices. Then, the combination of the devices at the stage where all the relevant devices are added is specified as the ZEH realization device group, and the ZEH realization device group is determined by this (S034).

Returning to the device proposal flow, when the employee specifies the third proposal condition (Yes in S011), the employee's personal computer carries out the third device identification process as the device identification process, and the third device identification process is performed. A group of ZEH realization devices satisfying the proposed conditions is specified (S012).

Explaining the flow of the third device specifying process with reference to FIG. 10, first, the combination of the cheapest devices selected in step 005 is tentatively set as the ZEH realization device group (S041). Next, it is determined whether or not there is a device having a greater energy saving effect than the cheapest device among the energy-related devices whose device information is registered in the database server 2 (S042). Then, when it is determined that the device corresponding to the above requirements does not exist, the combination of the cheapest devices is specified as the ZEH realization device group, and the ZEH realization device group is determined by this (S045).

On the other hand, when it is determined that the relevant device exists, it is further determined whether or not the total amount of the device introduction cost when the relevant device is introduced is within the budget amount indicated by the budget information acquired in step S002. (S043). At this time, if it is determined that the total equipment introduction cost exceeds the range of the budget amount, the combination of the cheapest equipment is specified as the ZEH realization equipment group, and the ZEH realization equipment group is determined by this (S045). On the other hand, if it is determined that the total equipment introduction cost is within the budget amount, the corresponding equipment (that is, the equipment with the greater energy saving effect) and one of the cheapest equipment (that is, the equipment). Replace with (equipment with smaller energy saving effect) (S044). At this time, it is preferable to preferentially select the device having the largest energy saving effect, and to replace the device having the lowest energy saving effect among the cheapest devices in order.

As long as there is a device that has a greater energy-saving effect than the device that is currently a candidate for the ZEH realization device group, and the total cost of introducing the device is within the budget amount, the above step S044 Is repeated. Then, the combination of equipment at the time when there is no equipment that can obtain a larger energy saving effect, or the combination of equipment at the time immediately before the total equipment introduction cost exceeds the budget amount is specified as the ZEH realization equipment group, and this is used. The ZEH realization device group is determined (S045).

In the device identification process described above, when the ZEH realization device group that satisfies the proposal condition specified by the user is specified (determined), the employee's personal computer displays the identification result as shown in FIG. Generate the output screen data shown. Then, the above-mentioned personal computer outputs the above-mentioned specific result by expanding the generated output screen data (S013). As a result, the output screen shown in FIG. 2 is drawn on the display of the personal computer, and the identification result of the ZEH realization device group, that is, the list of each energy-related device related to the ZEH realization device group is displayed (output) through the output screen. Will be done. That is, this step S013 corresponds to the output process, and through this step S013, the employee proposes the output ZEH realization device group to the person who plans to purchase the house.

Then, the device proposal flow is completed when the ZEH realization device group is displayed (presented) on the output screen.
