Next, the operation of the exterior renovation proposal system 10 will be described. FIG. 3 is a sequence diagram of the operation of the exterior renovation proposal system 10.

  The basic specification screen, which is the top screen of the exterior reform proposal system 10, is displayed using an operation through a customer information list screen used in a customer information management system different from the exterior reform proposal system 10 as a trigger. FIG. 4 is a diagram showing an example of the customer information list screen.

  The customer information list screen is a display screen provided by the customer information management system configured by the first server device 20 and the information terminal 40. Display screen information for displaying a customer information list screen is provided from the first server device 20 by transmitting a request for customer information from the information terminal 40.

  As described above, the customer information is information of a customer who built a house at a specific house maker. The customer information includes a customer code, a customer name, a house type number, and a total floor area. In addition, part or all of the customer information is used as housing specification information.

  When the customer information list screen is displayed on the display unit 44 (S11), the user selects one piece of customer information through the customer information list screen and taps the icon 44a. In other words, the tap operation on the icon 44a is a start-up operation for starting up the exterior renovation proposal system 10.

  When a tap operation to the icon 44a, that is, a start-up operation, is received by the reception unit 41 (S12), the communication unit 43 performs a second request for display screen information of the basic specification screen based on the control of the control unit 42. It transmits to the server apparatus 30 (S13). The request includes, for example, identification information of customer information selected by the user. For example, a customer code is used as the identification information, but dedicated identification information other than the bonus code may be used.

  When the request for the display screen information of the basic specification screen is received by the communication unit 31 of the second server device 30 (S14), the control unit 32 transmits the customer information including the identification information included in the request for the display screen information. A request is sent to the communication unit 31 (S15). The communication unit 21 of the first server device 20 receives the request for the customer information (S16), and transmits the customer information specified by the identification information included in the received request based on the control of the control unit 22 ((6) S17). As a result, the communication unit 31 of the second server device 30 can acquire customer information from the first server device 20 (S18). As described above, the customer information includes housing specification information.

  Subsequently, the control unit 32 of the second server device 30 reads the display screen information of the basic specification screen stored in the storage unit 34 (S19), and uses the read display screen information as the customer acquired in step S18. After reflecting the content of the information, the communication unit 31 is made to transmit (S20). The transmitted display screen information is received by the communication unit 43 of the information terminal 40 (S21), and the display unit 44 displays the basic specification screen based on the display screen information received by the communication unit 43 (S22). FIG. 5 is a diagram showing an example of the basic specification screen.

  Thereafter, the display screen displayed on the display unit 44 changes based on the display screen information transmitted by the second server device 30 each time the operation on the display screen being displayed is received by the reception unit 41. FIG. 6 is a view showing screen transition of the display unit 44. As shown in FIG. Hereinafter, each display screen displayed on the display unit 44 will be described.

  In the example of FIG. 5, a check mark 44b is given to the type of the house "R", the number of floors "second floor", and the area "general ground". That is, in the customer information acquired in the step S18, the house type is registered as “R”, the floor number is “2nd floor”, and the area is “general place”, and this content is set as an initial setting in the basic specification screen. It is reflected. The same applies to the subsequent display screens.

[House specification screen]
When the “forward” icon at the lower right of the screen in the basic specification screen is tapped, the display unit 44 displays the housing specification screen 1. FIG. 7 is a diagram showing an example of the house specification screen 1.

The house specification screen 1 shown in FIG. 7 includes the total floor area and the type of outer wall material. In the example of FIG. 7, the total floor area “100 m ² ” is input, and the outer wall material “siding (organic)” is given a check mark. That is, in the customer information acquired in step S18, a total floor area of 100 m ² and an outer wall material “siding (organic)” are registered, and the contents thereof are reflected on the house specification screen 1 as an initial setting.

  In the housing specification screen 1, when the “return” icon at the lower left of the screen is tap-operated, the display unit 44 displays the above-described basic specification screen. On the other hand, in the housing specification screen 1, when the “forward” icon at the lower right of the screen is tap-operated, the display unit 44 displays the housing specification screen 2. FIG. 8 is a diagram showing an example of the house specification screen 2.

  The house specification screen 2 shown in FIG. 8 includes a roof shape, a roof slope, and a type of roofing material. In the example of FIG. 8, a check mark is attached to the roof shape “yodo”, a roof slope “10: 3” is input, and a check mark is attached to the roof material type “slate”. That is, in the customer information acquired in step S18, the roof shape “Yard”, the roof slope 10: 3, and the roof material type “slate” are registered, and this content is reflected on the house specification screen 2 There is.

  In the housing specification screen 2, when the “return” icon at the lower left of the screen is tap-operated, the display unit 44 displays the housing specification screen 1 described above. On the other hand, when the icon of “advance” on the lower right of the housing specification screen 2 is tapped, the display unit 44 displays the housing specification screen 3. FIG. 9 is a view showing an example of the house specification screen 3.

  The house specification screen 3 shown in FIG. 9 includes the presence or absence of the eaves-end cut / gradient eaves ceiling, the type of the waist wall of the balcony, the presence or absence of the partial flat, the presence or absence of the entrance porch, and the presence or absence of the understory. In the example of FIG. 9, a check mark is attached to “Available” for the eaves-end cut / gradient eaves ceiling, and a check mark is attached to “outer wall material specification” for the type of waist wall of the balcony. For partial flats, a check mark is given to "yes", a check mark is given to "no" for the entrance porch, and a check mark is given to "presence" for the lower case. The check marks on the housing specification screen 3 are also initialized based on the contents of the customer information acquired in step S18. In the following embodiment, the information shown on the house specification screen 3 is also described as detailed specification information indicating the detailed specification of the exterior of the house.

  Further, in the housing specification screen 3, the input of the quantity or the dimension is also performed. For example, the number of sides is input for an eaves-cut and a slope eaves ceiling.

  As described above, the contents of the customer information acquired in step S18 are reflected on the basic specification screen and the housing specification screens 1 to 3. When the customer information is missing or the customer information is changed, the user can also input the information or change the information by an operation through each display screen. In this case, the changed customer information is appropriately transmitted to the second server device 30, and is used for narrowing down selection candidates on the selection screen and calculation of the estimated amount.

[Reform site selection screen]
In the housing specification screen 3, when the “forward” icon at the lower right of the screen is tap-operated, the display unit 44 displays a reform part selection screen. FIG. 10 is a diagram showing an example of the reforming site selection screen.

  The reform site selection screen is a screen for the user to select a site of exterior remodeling. As shown in FIG. 6 above, it is possible to transition to four selection screens from the reform site selection screen.

  Further, the remodeling site selection screen is an example of an estimation screen, and the remodeling site selection screen displays the total estimated amount of money for exterior remodeling. In the example of FIG. 10, the total estimated amount of exterior remodeling is displayed in the upper right portion of the remodeling site selection screen. The total estimated amount of exterior renovation changes according to the selection result on the above four selection screens. The total estimated amount of the initial exterior renovation is set, for example, to the amount when a predetermined standard specification is selected on each of the four selection screens.

[Exterior wall reform selection screen]
When the reform site selection screen is displayed on the display unit 44 and the icon including the characters “outer wall” is tapped, the display unit 44 displays the outer wall reform selection screen. FIG. 11 is a diagram showing an example of the outer wall reform selection screen. The outer wall reform selection screen is an example of a first selection screen, and is configured by superimposing a pop-up image on the reform region selection screen.

  In the outer wall reform selection screen, there are three candidates for selection of large divisions: tile construction, outer wall painting, and replacement of sealing material. The outer wall reforming selection screen may include at least one of tile construction, outer wall painting, and sealing material replacement as selection candidates for the outer wall reforming. In the example of FIG. 11, the tile application includes two selection candidates of patterns 1 and 2, the painting (spraying) includes three selection candidates of patterns 1 to 3, and the painting (multicolor) The five selection candidates of patterns 1 to 5 are included, and the coating (single color) includes four selection candidates of patterns 1 to 4. In the case of no painting, there are two selection candidates of "Replacement of sealing" and "None". In addition, "replacement of sealing" is selected when the user does not perform the application of the tile and the painting of the outer wall but only wishes to replace the sealing material. "None" is selected when the customer does not want to reform the exterior wall.

  In the outer wall reform selection screen, a plurality of selection candidates are arranged by grade. Specifically, the installation of the tile, which is the exterior wall reform located at the top row in the exterior wall reform selection screen, is the highest grade and the construction cost is high. The lower the outer wall reform located on the lower row in the outer wall reform selection screen, the lower the grade and the lower the construction cost.

  As described above, if a plurality of selection candidates are arranged for each grade, it is easy to select the exterior wall reform in consideration of the construction cost.

  By the way, these selection candidates are narrowed down in advance based on the customer information acquired from the first server device 20. FIG. 12 is a flowchart of the display operation of the outer wall reform selection screen with selection candidates narrowed down.

  First, the communication unit 31 of the second server device 30 acquires customer information in advance (S31). The customer information is acquired by, for example, the communication unit 31 at the timing of step S18 in the sequence diagram of FIG. The communication unit 31 is an example of an acquisition unit. As mentioned above, the customer information includes housing specification information.

  Next, the control unit 32 displays the display screen information in which the selection candidates are narrowed down based on the acquired customer information, the exterior renovation matching information on the outer wall stored in the storage unit 34, and the display screen information as a base. Generate (S32). FIG. 13 is a diagram showing an example of exterior reform fit information regarding the outer wall.

  As shown in FIG. 13, exterior renovation compatible information regarding the outer wall is information indicating whether or not construction of each of a plurality of exterior wall renovations is possible for a house having a certain house type number. In FIG. 13, ○ indicates that construction is possible, and x indicates that construction is impossible. The impossibility of construction here includes both cases where construction is difficult due to construction methods and cases where construction itself is possible but quality can not be maintained. That is, the impossibility of construction here is not a strict meaning. In the example of FIG. 13, whether or not a plurality of outer wall reforms can be installed is shown for each housing type number, but in the exterior reform conformity information regarding the outer wall, the type of outer wall material currently installed in the customer's house etc. The construction availability may be indicated for each of the other parameters.

  According to the exterior renovation compatibility information, the control unit 32 performs an exterior wall renovation that can be implemented in a customer's residence currently receiving a proposal for exterior renovation based on the housing type number included in the customer information acquired in step S31. It can be determined.

  For example, in the case where the house type number is E, according to the exterior renovation compatibility information, it can be determined that the paint (color) pattern 6 can not be constructed. Then, the control unit 32 generates display screen information in which the painted (multicolor) pattern 6 is excluded from the selection candidates, using the display screen information as a base. The generated display screen information is stored, for example, in the storage unit 34. Then, when the request for display screen information from the communication unit 43 of the information terminal 40 is received by the communication unit 31, the control unit 32 causes the communication unit 31 to transmit the generated display screen information.

  Thereafter, when the remodeling site selection screen is displayed on the display unit 44 and the icon including the character of the outer wall is tapped, the communication unit 43 transmits a request for display screen information of the outer wall renovation selection screen, As a response, the display screen information generated in step S32 is received. The display unit 44 displays an outer wall reform selection screen in which selection candidates are narrowed down based on the display screen information received by the communication unit 43 (S33). That is, the outer wall reform selection screen displayed by the display unit 44 includes only some of the selection candidates determined based on the acquired customer information among the plurality of selection candidates. In other words, the display unit 44 displays the selection screen of the exterior wall reform that can be constructed in the home of the customer determined based on the acquired customer information. Thereafter, the reception unit 41 receives the selection of the user through the outer wall reform selection screen (S34).

  As described above, if the external wall reform selection screen is displayed that does not include the external wall renovation that is determined not to be implemented in the customer's residence as a selection candidate, the external wall renovation that can not be implemented in the customer's residence is erroneously proposed. Is suppressed. That is, according to the exterior remodeling proposal system 10, even an inexperienced salesperson can propose an appropriate exterior remodeling.

  FIG. 14 is a diagram showing an example of the outer wall reform selection screen. The selection screen shown in FIG. 14 is a selection screen on which an image for selecting the type of the existing outer wall material before remodeling is pop-up displayed when the tile pattern 1 is selected. In the case of remodeling the outer wall using tiles, first, the ground adjustment is performed to flatten the existing outer wall, and then the tile is attached with an adhesive. The condition of the unevenness of the existing outer wall differs depending on the type of existing outer wall material. For this reason, the degree and method of base adjustment differ by the kind of existing outer wall material. The cost of base preparation also varies depending on the type of existing outer wall material.

  Therefore, when a tile is selected on the outer wall reform selection screen in order to include the cost for the background adjustment in the estimated amount, a screen for selecting the type of the existing outer wall material is displayed. Thereby, the user can select the existing outer wall material through the outer wall reform selection screen. In addition, the kind of existing outer wall material may be specified based on customer information (house specification information). That is, the cost of the background adjustment may be identified based on the customer information.

[Roof reform selection screen]
When the remodeling site selection screen is displayed on the display unit 44 and the icon including the characters “roof” is tapped, the display unit 44 displays the roof renovation selection screen. FIG. 15 is a diagram showing an example of a roof renovation selection screen. The roof renovation selection screen is an example of a second selection screen, and is configured by superimposing a pop-up image on the renovation site selection screen.

  The roof renovation selection screen includes three options, that is, roof resurfacing, roof overlaying, and roof painting, as major segment selection options. The roof renovation selection screen may include at least one of roof resurfacing, roof overlaying, and roof painting as a selection candidate. In the example of FIG. 15, the roof resurfacing includes three selection candidates of patterns 1 to 3, the overlapping roof of roof includes three selection candidates of patterns 1 to 3, and the roof coating includes Two selection candidates of patterns 1 and 2 are included. "None" is selected when the customer does not want to renovate the roof.

  In addition, resurfacing of the roof means replacing the existing roofing material with new roofing material, layering of the roof means constructing new roofing material on the existing roofing material, and coating of the roof , Means to apply paint to the existing roofing material.

  In the roof renovation selection screen, a plurality of selection candidates are arranged by grade. Specifically, the roof refinishing, which is the roof reform located at the top row in the roof reform selection screen, is the highest grade and the construction cost is high. And, the lower the roof renovation located on the lower row in the roof renovation selection screen, the lower the grade and the lower the construction cost.

  Thus, if a plurality of selection candidates are arranged by grade, it is easy to select a roof renovation in consideration of the construction cost.

  Similar to the exterior wall renovation selection screen, in the roof renovation selection screen, the selection candidates are narrowed down in advance based on the customer information and the exterior renovation matching information on the roof. FIG. 16 is a diagram showing an example of exterior renovation matching information on a roof.

  As shown in FIG. 16, exterior renovation compatible information on the roof is information indicating whether or not construction of each of a plurality of roof renovations is possible for a house having a certain house type number. In FIG. 16, ○ indicates that construction is possible, and x indicates that construction is not possible. The impossibility of construction here includes both cases where construction is difficult due to construction methods and cases where construction itself is possible but quality can not be maintained. That is, the impossibility of construction here is not a strict meaning. In the example of FIG. 16, whether or not a plurality of roof reforms can be installed is shown for each housing model number, but in the exterior reform compatible information regarding the roof, the type of roof material currently installed in the customer's house, etc. The construction availability may be indicated for each of the other parameters.

  The control unit 32 can determine, based on the house type number included in the customer information, the roof reform applicable to the house of the customer who is currently receiving the proposal for the exterior reform.

  For example, when the house type number is E, according to the exterior renovation suitability information, it can be determined that the reworking pattern 3 can not be constructed. Then, the control unit 32 generates display screen information in which the switching pattern 3 is excluded from the selection candidates using the display screen information serving as a base. The generated display screen information is stored, for example, in the storage unit 34.

  The display unit 44 displays a roof reform selection screen in which selection candidates are narrowed down based on such display screen information. In other words, the display unit 44 displays a selection screen of a roof renovation that can be constructed in the customer's house, which is determined based on the acquired customer information.

  As described above, if a roof renovation selection screen is displayed that does not include as a selection candidate a roof renovation that is determined not to be implemented in the customer's residence, a roof renovation that can not be implemented in the customer's residence is mistakenly proposed. Is suppressed. That is, according to the exterior remodeling proposal system 10, even an inexperienced salesperson can propose an appropriate exterior remodeling.

  Although details are not illustrated, when a selection candidate is selected through the roof reform selection screen, a detail selection image for selecting details such as a pattern and a color is further popped up.

  By the way, when the customer's house is large and the roofing material is expected to be deteriorated, it is not possible to propose roofing reform using existing roofing material, that is, roofing remodeling other than repainting or layering roofs. It is appropriate. Therefore, when the customer information includes information indicating the age of the house, and the age of the customer's house is equal to or more than a predetermined number of years, the roof renovation selection screen may not include the coating of the roof as a selection candidate . The predetermined number of years is, for example, 30 years or more.

  Thus, the selection candidate included in the roof renovation selection screen may be changed according to the age of the customer's home. The same applies to selection candidates included in the outer wall reform selection screen. For example, when the age of the customer's house is equal to or more than a predetermined number of years, the exterior remodeling that uses the existing exterior material as it is is excluded from the selection candidates, and thus it is suppressed that the inappropriate exterior remodeling is proposed. Ru.

[Balcony renovation selection screen]
When the remodeling site selection screen is displayed on the display unit 44 and the icon including the characters "balcony" is tapped, the display unit 44 displays the balcony renovation selection screen. FIG. 17 is a diagram showing an example of a balcony renovation selection screen. The balcony renovation selection screen is an example of a third selection screen for selecting the renovation content of the balcony of the customer's house, and is configured by superimposing a pop-up image on the renovation site selection screen.

  The balcony renovation selection screen includes three choices of balcony flooring: magnetic tile type, mesh tile type, and plastic type. "None" is selected if the customer does not want to renovate the balcony. In addition, the balcony renovation selection screen includes an input unit for the dimensions of the balcony.

  As a result of displaying the selection screen of the renovation of the balcony in this manner, it is possible to prevent the salesperson from forgetting the proposal of the renovation of the balcony that is easily deteriorated over time.

[Accessory paint selection screen]
When the reform part selection screen is displayed on the display unit 44 and the icon including the characters "painted accessories" is tapped, the display unit 44 displays the accessory paint selection screen. FIG. 18 is a view showing an example of the accessory painting selection screen. The accessory paint selection screen is an example of a fourth selection screen for selecting whether or not to paint a plurality of parts related to the exterior of the customer's house, and a pop-up image is superimposed on the reform part selection screen It consists of The plurality of parts are, for example, an eaves ceiling, a shutter, a gutter, a gnarly hood, a chimney, a lattice balcony, and an external staircase, but is not particularly limited.

  In this way, when it is displayed whether or not to paint each of a plurality of parts related to the exterior of the customer's house, the customer and the salesperson should be aware of the presence or absence of the painting on the exterior of the fine part. Becomes easy. In other words, it is possible to suppress the occurrence of trouble based on the difference in recognition between the customer and the salesman.

[Calculation of estimated price for exterior wall reform]
As described above, the remodeling site selection screen shown in FIG. 10 displays the total estimated amount of exterior remodeling. The total estimated amount is the sum of the estimated amount for exterior wall reform, the estimated amount for roof renovation, the estimated amount for balcony reform, and the estimated amount for accessory painting.

  Here, the calculation method of the estimated amount of money of the outer wall reform will be described. In the exterior renovation proposal system 10, the area of the outer wall of the house is estimated based on the total floor area of the house included in the customer information. For example, for each of a plurality of existing houses, data of actual floor area and actual wall area are acquired, and correlation coefficients obtained by dividing the outer wall area by the total floor area are calculated in advance based on the data. Keep it. Assuming that the vertical axis is a correlation coefficient (= outer wall area / perforated floor area) and the horizontal axis is a total floor area, a graph as shown in FIG. 19 is obtained by statistical processing such as the least squares method. FIG. 19 is a graph schematically showing the relationship between the correlation coefficient for estimating the area of the outer wall and the total floor area.

  If the graph as shown in FIG. 19, that is, the relational expression is stored in advance in the storage unit 34, the calculating unit 33 of the second server device 30 copes with the floor area included in the customer information based on the relational expression. Correlation coefficient can be identified. Then, an approximate value of the area of the outer wall can be calculated based on the following (Equation 1).

    Estimated outer wall area = total floor area x correlation coefficient · · · (Equation 1)

  Here, the storage unit 34 stores, for each of the plurality of selection candidates displayed on the above-described outer wall renovation selection screen, the construction cost per unit area of the outer wall renovation of the selection candidate. The calculation unit 33 specifies the construction cost per unit area of the outer wall reform selected through the outer wall reform selection screen by referring to the storage unit 34, and multiplies the construction cost per unit area specified by the estimated outer wall area It is possible to calculate the estimated price of the exterior wall reform.

  As described above, the calculation unit 33 estimates the area of the outer wall of the house based on the total floor area, and makes a selection through the estimated area of the outer wall of the house and the outer wall reform selection screen received by the reception unit 41. Calculate the estimated price of exterior wall reform based on the above. The control unit 32 generates display screen information for displaying an estimation screen including the total estimated amount to which the calculated estimated amount is added, and causes the communication unit 31 to transmit the generated display screen information. Based on the display screen information received by the communication unit 43, the display unit 44 displays a reformed part selection screen including the total estimated amount.

  Thus, the exterior renovation proposal system 10 can calculate the estimated price of the exterior wall renovation without actually measuring the area of the exterior wall of the customer. In addition, the display unit 44 may display the estimated price of the exterior wall reform alone.

  In addition, the construction cost per unit area of outer wall reform is determined based on the selection result through the outer wall reform selection screen shown in FIG. For example, in the storage unit 34, construction unit price information indicating the construction unit price of each of the outer wall reform selection candidates (tile-pattern 1, tile-pattern 2, painting (spray) -pattern 1 ...) is stored. The construction unit price is previously determined for each selection candidate of the exterior wall reform based on the material cost of the pattern of the selection candidate, the construction cost, and the like. Moreover, although basement adjustment is required when performing an outer wall reform using a tile, the expense of basement adjustment changes with kinds of existing outer wall material. For this reason, in the storage unit 34, for example, base adjustment unit price information indicating the unit cost of the base adjustment for each type of existing outer wall material is stored.

  Then, when the exterior wall renovation using the tile is selected, the calculation unit 33 specifies the construction unit price corresponding to the selection candidate selected through the exterior wall reform selection screen based on the construction unit price information. In addition, the calculation unit 33 specifies the unit price of the ground adjustment corresponding to the type of the existing outer wall before the reform selected through the outer wall reform selection screen, based on the ground adjustment unit price information. The construction cost per unit area of the outer wall reform is the sum of the specified construction unit price and the specified unit price of the ground adjustment.

  In addition, on the housing specification screen 3 shown in FIG. 9 described above, the presence or absence of an eaves-end cut / gradient eaves ceiling, the type of waist wall of a balcony, the presence or absence of a partial flat, the presence or absence of an entrance porch, and the presence or absence of an underlayment etc. Detailed specification information is included. The calculation unit 33 may correct the estimated amount of money for the exterior wall reform based on the detailed specification information indicating the detailed specification of the exterior of the house.

  For example, if the correction value of the outer wall area per unit quantity or unit dimension is previously determined and stored in the storage unit 34 for each item of the detailed specification information, the calculation unit 33 calculates such a correction value, and It is possible to correct the estimated price of exterior wall reform based on the customer information. In this case, the display unit 44 displays an estimation screen including the total estimated amount obtained by adding the estimated and calculated estimated value of the exterior wall reform calculated and corrected.

  As described above, if the estimated amount of the external wall reform is corrected based on the detailed specification information, it is possible to enhance the calculation accuracy of the estimated amount of the external wall reform.

[Calculation of estimated price for roof renovation]
Next, a method of calculating the estimated amount of roof renovation will be described. In the exterior renovation proposal system 10, the area of the roof of the house is estimated based on the total floor area of the house included in the customer information. For example, for each of a plurality of existing houses, data of actual floor area and data of actual roof projected area are obtained, and the projected roof area is divided by the total floor area based on the data. Calculate the relation number in advance. Assuming that the vertical axis is the correlation coefficient (= projected area of the roof / the spread floor area) and the horizontal axis is the total floor area, a graph as shown in FIG. 20 is obtained by statistical processing such as the least squares method. FIG. 20 is a graph schematically showing the relationship between the correlation coefficient and the total floor area for estimating the area of the roof.

  In addition, when calculating | requiring the projection area of a roof from a total floor area, the relationship changes with the number of floors of a house greatly. For this reason, the data of the actual floor area and the data of the actual roof projected area are collected for houses having the same floor number, and a graph as shown in FIG. 20 is created for each floor, for example.

  If the graph as shown in FIG. 20, that is, the relational expression is stored in advance in the storage unit 34, the calculating unit 33 of the second server device 30 copes with the floor area included in the customer information based on the relational expression. Correlation coefficient can be identified. Then, the rough value of the area of the roof can be calculated based on the following (Equation 2). In addition, the information which shows the inclination of a roof is contained in customer information, and the coefficient information which shows the coefficient according to the inclination of a roof is stored beforehand by the memory | storage part 34, for example.

    Estimated roof area = total floor area x correlation coefficient x coefficient according to roof slope · · · (Equation 2)

  Here, the storage unit 34 stores, for each of the plurality of selection candidates displayed on the above-described roof renovation selection screen, the construction cost per unit area of the roof renovation of the selection candidate. The calculation unit 33 specifies the construction cost per unit area of the roof renovation selected through the roof reform selection screen by referring to the storage unit 34, and multiplies the construction cost per unit area thus identified by the estimated roof area It is possible to calculate the estimated price of the roof renovation.

  In this manner, the calculation unit 33 estimates the area of the roof of the house based on the total floor area and the slope of the roof, and the estimated area of the roof of the house and the roof renovation selection screen accepted by the accepting unit 41 Calculate the estimated value for roof renovation based on your selection through. The control unit 32 generates display screen information for displaying an estimation screen including the total estimated amount to which the calculated estimated amount is added, and causes the communication unit 31 to transmit the generated display screen information. Based on the display screen information received by the communication unit 43, the display unit 44 displays a reformed part selection screen including the total estimated amount.

  Thus, the exterior renovation proposal system 10 can calculate the estimated amount of roof renovation without actually measuring the area of the roof of the customer. In addition, the display part 44 may display the estimated amount of roof reform independent.

  In addition, on the housing specification screen 3 shown in FIG. 9 described above, the presence or absence of an eaves-end cut / gradient eaves ceiling, the type of waist wall of a balcony, the presence or absence of a partial flat, the presence or absence of an entrance porch, and the presence or absence of an underlayment etc. Detailed specification information is included. The calculation unit 33 may correct the estimated value of the roof renovation based on the detailed specification information indicating the detailed specification of the exterior of the house.

  For example, if the correction value of the roof area per unit quantity or unit dimension is previously determined and stored in the storage unit 34 for each item of the detailed specification information, the calculation unit 33 calculates such a correction value, and The estimated value of roof reform can be corrected based on customer information. In this case, the display unit 44 displays an estimation screen including the total estimated amount of money to which the estimated and calculated amount of roof reform calculated and corrected is added.

  As described above, if the estimated amount of roof renovation is corrected based on the detailed specification information, it is possible to improve the calculation accuracy of the estimated amount of roof renovation.

[Display of caution screen]
