DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] <Embodiment> The gutter evaluation device of this embodiment will be described below. The gutter evaluation device of this embodiment evaluates the amount of CO2 (carbon dioxide (one example of greenhouse gas)) emissions corresponding to the components constituting the gutter to be installed on a building. Since CO2 is emitted in the life cycle of the gutter components from their manufacture to their disposal and reuse, the gutter to be installed on one building will have CO2 emissions according to the number and size of the components constituting the gutter. Considering this, evaluating the CO2 emissions (LCCO2 (life cycle CO2) emissions) of the gutter installed on a building leads to understanding the environmental performance of the gutter, and therefore can be said to be meaningful from the perspective of, for example, global environmental protection.

[0018] The scale of the gutter to be installed varies depending on, for example, the scale and style of the building. Since the quantity and materials of the components used vary depending on the scale of the gutter, the CO2 emissions corresponding to the gutter to be installed vary for each building. The gutter evaluation device of this embodiment can evaluate the CO2 emissions of the gutter to be installed for each property such as a building.

[0019] In addition, the gutter evaluation device of the embodiment is configured to be capable of evaluating the CO2 emission amount corresponding to the gutter to be installed as described above, as well as the installation cost corresponding to the same gutter to be installed. In the following explanation, the CO2 emissions and construction costs associated with such gutters will be considered as the "performance" of the gutters, and the evaluation of the CO2 emissions, construction costs, etc. will also be referred to as "performance evaluation."

[0020] The gutter evaluation device of this embodiment may be configured by installing a gutter performance evaluation application on a personal computer, a smartphone, a tablet terminal, or the like.

[0021] Next, an example of a procedure for a user to evaluate the performance of a gutter to be constructed using the gutter evaluation device of this embodiment will be described. When using the gutter evaluation device to evaluate the performance of a gutter to be constructed, a user first displays an evaluation parameter input screen on the gutter evaluation device and then inputs specified evaluation parameters (an example of an information item) into the displayed evaluation parameter input screen.

[0022] FIG. 1 shows an example of an evaluation parameter input screen in which evaluation parameters have been input by a user operation. The evaluation parameter input screen includes a basic information input area AR1 and a gutter structure information input area AR2. In the basic information input area AR1, basic information that is fundamental regarding the gutter to be constructed is input as an evaluation parameter. In the figure, an example is shown in which each basic information such as the submission destination, the submission source, the property name, the submission date, the rainfall intensity, the target roof area, and the structure type can be input as basic information in the basic information input area AR1. The destination of submission indicates the party to which the corresponding performance evaluation results are to be submitted. The submitter indicates a party that performs a corresponding performance evaluation and submits the evaluation result to the submitter. The property name indicates the name of the property where the rain gutter to be installed is to be installed. The submission date indicates the date on which the corresponding performance evaluation results are submitted to the recipient. The target roof area indicates the roof area of ​​the property on which the target rain gutter is to be installed. The structural type indicates the structural type of the rain gutter to be installed. The structural type can be, for example, a flat roof type, an eaves gutter type, etc. The structure of the rain gutter differs greatly depending on whether the building has a flat roof or a half-ridge roof, hip roof, gable roof, etc.

[0023] In the gutter structure information input area AR2, predetermined information (structural information) related to the structure of the gutter to be constructed is input as an evaluation parameter. In the same figure, an example is shown in which each piece of information such as vertical gutter size, vertical gutter system number, vertical gutter height, eaves gutter length, and eaves gutter size can be input as the gutter structure information in the gutter structure information input area AR2. The vertical gutter size indicates the size (diameter) of the pipe used in the vertical gutter in the structure of the rain gutter to be constructed. The diameter of the pipe size here may be the nominal diameter, the inner or outer diameter of the pipe, the inner cross-sectional area, etc. The number of vertical gutters (number of vertical gutters) indicates the number of vertical gutters in the structure of the gutter to be installed. For example, one vertical gutter system is the part that branches off from the eaves gutter and extends downward to the mouth where water is discharged at the bottom. The vertical gutter height is the length of one vertical gutter system in the rain gutter to be installed. If the rain gutter to be installed has multiple vertical gutter systems, the vertical gutter height may be common to the multiple vertical gutter systems. The eaves gutter length indicates the total length of the eaves gutters included in the gutter to be installed. The eaves gutter size may indicate the size of the eaves gutter included in the rain gutter to be installed, for example, the dimensions, specifications, product number, etc. of the eaves gutter.

[0024] In this embodiment, the structure of the rain gutter to be constructed can be one of two different specifications: a high-efficiency drainage specification and a general drainage specification. The high-efficiency drainage specification is a rain gutter specification in which a drainage member that easily induces the siphon principle is provided at the water inlet of the downpipe to increase the drainage capacity of the downpipe system. The general drainage specification is a rain gutter specification in which a drainage member that easily induces the siphon principle is not provided in the downpipe system. In this embodiment, the gutter evaluation device is capable of comparing and outputting the calculated performance results for when the gutters to be installed on the same property (building) are of high-efficiency drainage specification and when they are of general drainage specification, in performance evaluation.

[0025] In response to the above-mentioned ability to compare performance between the high-efficiency drainage specification and the general drainage specification, in the gutter structure information input area AR2, it is possible to input structural information (as gutter structure information, vertical gutter size, number of vertical gutter systems, vertical gutter height, eaves gutter length, and eaves gutter size) for each of the two gutter structure specifications, the high-efficiency drainage specification and the general drainage specification. When comparing the structural information of the high-efficiency drainage specification shown in the figure with that of the general drainage specification, the size of the vertical gutter is different. Since the high-efficiency drainage specification is more efficient in that the amount of water flowing into the vertical gutter per cross-sectional area is greater than that of the general drainage specification, the size (diameter) of the vertical gutter required for the required amount of drainage can be smaller. On the other hand, here, an example is given in which the number of vertical gutter systems, vertical gutter height, eaves gutter length, and eaves gutter size other than the vertical gutter size in the structural information are the same for the high-efficiency drainage specification and the general drainage specification. In this case, since the buildings to which the gutters are installed are the same, the number of vertical gutter systems, vertical gutter height, eaves gutter length, and eaves gutter size can be treated as the same for the high-efficiency drainage specification and the general drainage specification.

[0026] Input of information on the evaluation parameter input screen may be performed by a character input operation, or may be performed by a selection operation for options on a pull-down menu or the like.

[0027] As shown in Fig. 1, an execution calculation button BT1 is arranged on the evaluation parameter input screen. When the user completes the operation of inputting the evaluation parameters, the user operates the execution calculation button BT1 to cause the gutter evaluation device to execute calculations for performance evaluation.

[0028] In response to the operation of the calculation execution button BT1, the gutter evaluation device executes a calculation for evaluating the performance of the gutter to be constructed, using the evaluation parameters inputted into the evaluation parameter input screen. The gutter evaluation device calculates the CO2 emission amount and construction cost as the performance of the gutter. In response to the input of the evaluation parameters on the evaluation parameter input screen, the gutter evaluation device may execute a calculation for performance evaluation using the input evaluation parameters, and output the calculation result by display, etc. In this case, the calculation execution button BT1 on the evaluation parameter input screen may be omitted.

[0029] The gutter evaluation device can generate CO2 emission evaluation information indicating the calculation results regarding the CO2 emission amount, and output the generated CO2 emission evaluation information in a predetermined form. 2 shows an example of a CO2 emission evaluation sheet that is output in accordance with a format for presenting the CO2 emission evaluation information to a submission destination. Such a CO2 emission evaluation sheet may be output by display or printing.

[0030] The CO2 emission assessment sheet in the figure shows an example in which a basic information area AR11, a gutter structural specification classification area AR12, an assessment result area AR13, and an assessment result graph area AR14 are arranged.

[0031] The basic information area AR11 is an area in which the basic information input in the basic information input area AR1 (FIG. 1) of the evaluation parameter input screen is presented.

[0032] The gutter structure specification classification area AR12 is an area that shows the number of gutter systems and the gutter height values ​​entered in the gutter structure information input area AR2 of the evaluation parameter input screen, classified according to the gutter structure specification (general drainage specification, high-efficiency drainage specification).

[0033] The evaluation result area AR13 shows the CO2 emission amount (LCCO2 emission amount) of the general drainage specification and the high-efficiency drainage specification as the evaluation result of the CO2 emission amount, and the CO2 reduction amount and reduction rate compared to the general drainage specification when the high-efficiency drainage specification is adopted as the comparison result. Note that the evaluation result area AR13 may show either the CO2 reduction amount or the reduction rate.

[0034] The evaluation result graph area AR14 is an area that shows the CO2 emission amount of the general drainage specification and the CO2 emission amount of the high-efficiency drainage specification in a graph. In the same figure, an example is given in which the CO2 emission amount of the general drainage specification and the CO2 emission amount of the high-efficiency drainage specification are each shown as a bar graph, but the type of graph and the way of presenting the graph are not particularly limited.

[0035] Furthermore, the gutter evaluation device can generate construction cost evaluation information indicating the calculation results regarding the construction costs of the gutter, and output the generated construction cost evaluation information in a predetermined form. 3 shows an example of a construction cost evaluation sheet that is output in accordance with a format for presenting construction cost evaluation information to a submission destination. Such a construction cost evaluation sheet may also be output by display or printing.

[0036] The construction cost evaluation sheet in the figure shows an example in which a basic information area AR11, a gutter structural specification classification area AR12, an evaluation result area AR13, and an evaluation result graph area AR14 are arranged.

[0037] The basic information area AR11 is an area in which the basic information input in the basic information input area AR1 (FIG. 1) of the evaluation parameter input screen is presented.

[0038] The gutter structure specification classification area AR12 is an area that shows the number of gutter systems and the gutter height values ​​entered in the gutter structure information input area AR2 of the evaluation parameter input screen, classified according to the gutter structure specification (general drainage specification, high-efficiency drainage specification).

[0039] The evaluation result area AR13 shows the construction costs (construction costs) of the general drainage specification and the high-efficiency drainage specification as the construction cost evaluation result, and the cost reduction amount and reduction rate when the high-efficiency drainage specification is adopted compared to the general drainage specification as the comparison result. Note that the evaluation result area AR13 may show either the cost reduction amount or the reduction rate.

[0040] The evaluation result graph area AR14 is an area that shows the construction costs of the general drainage specification and the high-efficiency drainage specification in a graph. In the figure, the construction costs of the general drainage specification and the high-efficiency drainage specification are each shown by a bar graph, and the breakdown of the construction costs (construction costs, material costs) is shown in each bar graph. There is no particular limit to the type of graph or the way of presenting the graph in such a construction cost evaluation sheet.

[0041] An example of the functional configuration of the gutter evaluation device 100 of this embodiment will be described with reference to Fig. 4. The gutter evaluation device 100 as hardware is configured to include a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), a storage device (HDD (Hard Disc Drive), SSD (Solid State Drive), etc.), a user interface (display device, input device), a communication module, etc. The functions of the gutter evaluation device 100 shown in Fig. 4 are realized by the CPU, GPU, etc. executing a program under the above hardware configuration.

[0042] The gutter evaluation device 100 in FIG. 4 includes a user interface unit 101, a communication unit 102, a control unit 103, and a storage unit 104. The user interface unit 101 includes a display device, an audio output device, and an input device (mouse, keyboard, touch panel, etc.), and receives operations from a user and displays and outputs sounds to the user.

[0043] The communication unit 102 communicates with other devices via a network. Note that, for example, in a case where the rain gutter evaluation device 100 of the present embodiment is capable of executing the processes from the rain gutter evaluation calculation to the output of the calculation result in a standalone manner, the communication unit 102 may be omitted.

[0044] The control unit 103 executes various controls in the gutter evaluation device 100. The control unit 103 includes an acquisition unit 131, a calculation unit 132, and an information output unit 133. The acquiring unit 131 acquires information as the evaluation parameters inputted on the evaluation parameter input screen. The calculation unit 132 performs calculations for evaluating the performance of the rain gutter based on the information serving as the evaluation parameters acquired by the acquisition unit 131. Specifically, the calculation unit 132 in this embodiment calculates the CO2 emission amount and construction cost of the rain gutter. The information output unit 133 generates performance evaluation information (CO2 emission amount evaluation information, construction cost evaluation information) related to the rain gutters based on the calculation results by the calculation unit 132, and outputs the generated performance evaluation information.

[0045] The storage unit 104 stores various information corresponding to the gutter evaluation device 100. The storage unit 104 includes a member database storage unit 141, a component member information storage unit 142, a construction cost information storage unit 143, and an evaluation information storage unit 144.

[0046] The member database storage unit 141 (an example of a first storage unit and a second storage unit) is a database that stores information on each member used in the rain gutters corresponding to the high-efficiency drainage specification and the general drainage specification. An example of the contents of the component database is shown in Figure 5. In this figure, one record (one row) stores component information corresponding to one component. The component information corresponding to one component includes fields for the product number, size, unit price, and unit CO2 emission amount. The part number field stores a part number (part identifier) ​​that is uniquely associated with the corresponding part. The size field stores the size defined for the corresponding member. The unit price field stores the unit price of the corresponding material (an example of material price information). The weight field stores the weight per unit quantity of the corresponding material. The field of unit CO2 emission stores the amount of CO2 emission per unit quantity of the corresponding component (unit CO2 emission (one example of component-related emission information)). The components shown in the component database may include pipe components such as vertical gutters and gutter components such as eaves gutters, as well as at least some of the auxiliary components such as joints that connect the gutter components to each other, supports that secure the vertical gutters and eaves gutters, expansion and contraction absorbing components that absorb the expansion and contraction of the gutter components, and adhesives.

[0047] Let us return to the explanation given in FIG. The component information storage unit 142 stores component information for each drainage specification of the gutter (high-efficiency drainage specification, general drainage specification). The component information is information indicating the quantity of components used according to the specification of the gutter.

[0048] Fig. 6(A) shows an example of component information stored in the component information storage unit 142. As shown in Fig. 6(A), the component information storage unit 142 stores component information corresponding to the high-efficiency drainage specification and component information corresponding to the general drainage specification. Fig. 6(B) shows an example of the structure of component information corresponding to one drainage specification. The component information in Fig. 6(B) is structured to store vertical gutter component information and eaves gutter component information for each structure type (flat roof type, eaves gutter type). The vertical gutter material information has a structure in which information on materials used is associated with each specified height. As shown in Fig. 6(C), the information on materials used indicates the quantity of each part number of materials required to form a vertical gutter of the corresponding height. The vertical gutter material information indicates the quantity of materials required for each height of a vertical gutter to be formed. The eaves gutter component information has a structure in which information on components used is associated with each predetermined length. The information on components used indicates the quantity of each component part number required to form an eaves gutter of the corresponding length. The eaves gutter component information indicates the quantity of components required for each length of the eaves gutter to be formed.

[0049] Let us return to the explanation given in FIG. The construction cost information storage unit 143 stores information (construction cost information) that is the basis for calculating construction costs. The construction cost information is used to calculate construction costs out of material costs and construction costs (construction labor costs). As a specific example, the construction cost information may be based on information on "construction work roof and gutter" in the standard unit price estimation standard for public construction work, information on "sheet metal work" in the public construction work design labor unit price, etc.

[0050] The evaluation information storage unit 144 stores evaluation information. The evaluation information is information indicating the performance evaluation result of the rain gutter to be constructed, and specifically, is information reflecting the calculation results of the calculation unit 132 on the CO2 emission amount, construction cost, etc. of the rain gutter to be constructed.

[0051] An example of a processing procedure executed by the gutter evaluation device 100 configured as described above in relation to performance evaluation will be described with reference to the flowchart of FIG. Step S100: The user starts the gutter performance evaluation application in the gutter evaluation device 100, and displays an evaluation parameter input screen (FIG. 1) which is an application screen of the gutter performance evaluation application. The user performs an operation to input evaluation parameters into the evaluation parameter input screen. In the gutter evaluation device 100, the acquisition unit 131 accepts the operation to input the evaluation parameters.

[0052] Step S102: The acquisition unit 131 acquires the evaluation parameters (basic information, structural information corresponding to the high-efficiency drainage specification, structural information corresponding to the general drainage specification) input by the operation accepted in step S100. The acquisition unit 131 may hold the acquired evaluation parameters by storing them in the storage unit 104. The acquiring unit 131 may acquire the received evaluation parameters in response to the communication unit 102 receiving the evaluation parameters transmitted by a destination terminal or the like via a network.

[0053] Step S104: First, the calculation unit 132 calculates the CO2 emission amount and the construction cost when the rain gutter to be constructed is of high-efficiency drainage specifications. Either the CO2 emission amount or the construction cost may be calculated first, but the case where the CO2 emission amount and the construction cost are calculated in that order will be taken as an example. The calculation unit 132 determines the quantity of components (used components) to be used when the gutter to be constructed is of the high-efficiency drainage specification, based on the component component information corresponding to the high-efficiency drainage specification among the component component information stored in the component component information storage unit 142. At this time, the calculation unit 132 specifies the quantity of each part number of the used parts corresponding to one system of the vertical gutter by referring to the used parts information stored in the vertical gutter part information of the component part information corresponding to the high-efficiency drainage specification, which matches the vertical gutter height in the evaluation parameters acquired in step S102. Then, the calculation unit 132 multiplies each of the specified quantities for each part number by the number of vertical gutter systems in the evaluation parameters acquired in step S102, thereby specifying the quantity of the used parts corresponding to all the vertical gutters in the rain gutter to be constructed. In addition, the calculation unit 132 identifies the quantity of each part number of parts used corresponding to the eaves gutter by referring to the used parts information that matches the eaves gutter length in the evaluation parameters acquired in step S102 from the used parts information stored in the eaves gutter part information of the component part information corresponding to the high-efficiency drainage specification. The calculation unit 132 can determine the quantity of each part number of parts used corresponding to the entire gutter by combining the quantity of each part number of parts used corresponding to the downspout identified as described above and the quantity of each part number of parts used corresponding to the eaves gutter. The information on used components may include auxiliary components such as joints, supports, expansion and contraction absorbing members, adhesives, etc., in addition to gutter components such as vertical gutters or eaves gutters. In this case, some of the auxiliary components may be excluded from the information on used components.

[0054] Step S106: Next, the calculation unit 132 acquires the weights of the parts used for the high-efficiency drainage gutter identified in step S104 and the unit CO2 emission amount per unit weight from the parts database stored in the parts database storage unit 141. The calculation unit 132 calculates the total weight of each part used that constitutes the gutter using the acquired weights for each part number, and calculates the CO2 emission amount corresponding to the entire high-efficiency drainage gutter using the calculated total weights of the parts used for each part number and the corresponding unit CO2 emission amount.

[0055] Step S108: Next, the calculation unit 132 calculates the construction cost when the rain gutter to be constructed is of high-efficiency drainage specifications. The construction cost includes the material cost, which is the cost of the materials used for the entire rain gutter, and the construction cost corresponding to the construction (construction) of the rain gutter. The calculation unit 132 acquires the price of each part number of the parts identified as the parts used in step S104 from the parts database stored in the parts database storage unit 141. The calculation unit 132 calculates the material cost corresponding to the entire gutter based on the acquired prices of each part number of the parts used and the quantities of each part number of the parts used identified in step S104. In addition, the calculation unit 132 calculates the construction cost corresponding to the gutter to be constructed, for example, based on the overall scale (size) of the gutter to be constructed, derived using the evaluation parameters acquired in step S102, and the construction cost shown as corresponding to the construction of the gutter in the construction information stored in the construction cost information storage unit 143. The calculation unit 132 calculates the construction cost in the case where the gutter is of high-efficiency drainage specifications by adding up the material cost and construction cost calculated as described above.

[0056] Step S110: Next, the calculation unit 132 calculates the CO2 emission amount and the construction cost when the rain gutter to be constructed is of general drainage specification. Even when the rain gutter is of general drainage specification, either the CO2 emission amount or the construction cost may be calculated first, but the case where the calculation is performed in the order of the CO2 emission amount and the construction cost will be taken as an example. The calculation unit 132 determines the quantity of components (used components) to be used when the gutter to be constructed is of general drainage specifications, based on the component component information corresponding to the general drainage specifications among the component component information stored in the component component information storage unit 142. For this purpose, the calculation unit 132 may perform processing similar to that of the previous step S104 by referring to the component information stored in the vertical gutter component information of the component information corresponding to the general drainage specification, which corresponds to the vertical gutter height in the evaluation parameters acquired in step S102.

[0057] Step S112: Next, the calculation unit 132 acquires the weights of the parts used that correspond to the rain gutter with general drainage specifications identified in step S110 and the unit CO2 emission amount per unit weight from the parts database stored in the parts database storage unit 141. The calculation unit 132 calculates the total weight of each part used that constitutes the rain gutter using the acquired weights of each part number, and calculates the CO2 emission amount corresponding to the entire rain gutter with general drainage specifications using the calculated total weights of the parts used that correspond to each part number and the corresponding unit CO2 emission amount.

[0058] Step S114: Next, the calculation unit 132 calculates the construction cost when the rain gutter to be constructed is of general drainage specifications. Even in the case of general drainage specifications, the construction cost may include the material cost, which is the cost of the materials used for the entire rain gutter, and the construction cost corresponding to the construction (construction) of the rain gutter. The calculation unit 132 acquires the price of each part number of the parts identified as the parts used in step S110 from the parts database stored in the parts database storage unit 141. The calculation unit 132 calculates the material cost corresponding to the entire gutter based on the acquired prices of each part number of the parts used and the quantities of each part number of the parts used identified in step S110. Furthermore, the calculation unit 132 calculates the construction cost corresponding to the rain gutter to be constructed, in the same manner as in the previous step S108. The calculation unit 132 calculates the construction cost in the case where the gutter is of general drainage specifications by adding up the material cost and the construction cost calculated as described above.

[0059] The order of the processing corresponding to the high-efficiency drainage specification in steps S104 to S108 and the processing corresponding to the general drainage specification in steps S110 to S114 may be interchanged, or the processing may be executed in parallel.

[0060] Step S116: The information output unit 133 generates CO2 emission evaluation information reflecting the processing results related to the CO2 emission amount so far. The CO2 emission evaluation information may be generated to have contents that can be output as a CO2 emission evaluation sheet as shown in Fig. 2. The information output unit 133 may store the generated CO2 emission evaluation information in the evaluation information storage unit 144.

[0061] Step S118: The information output unit 133 generates construction cost evaluation information reflecting the processing results related to the construction cost up to now. The construction cost evaluation information may be generated to have contents that can be output as a construction cost evaluation sheet as shown in Fig. 3. The information output unit 133 may store the generated construction cost evaluation information in the evaluation information storage unit 144. The order of the processes in steps S116 and S118 may be changed, or the processes may be executed in parallel.

[0062] Step S120: The information output unit 133 outputs evaluation information in response to a predetermined trigger, such as a user operation. The information output unit 133 may output either the CO2 emission evaluation information or the construction cost evaluation information, or may output both, in response to a designation by the operation, etc. The information output unit 133 may output the evaluation sheet so as to be displayed on a display device in the user interface unit 101, or may output the evaluation sheet so as to be printed on paper. The information output unit 133 may transmit the evaluation information from the communication unit 102 via a network to a predetermined terminal such as a recipient.

[0063] <Modification> A modification of this embodiment will now be described. [First Modification] In the example procedure of Fig. 7, both the CO2 emission amount and the construction cost are calculated for each of the high-efficiency drainage specification and the general drainage specification. However, the procedure may be such that either the CO2 emission amount or the construction cost is calculated for each of the high-efficiency drainage specification and the general drainage specification.

[0064] [Second modified example] The gutter evaluation device 100 may be capable of further evaluating the drainage amount as the performance of the gutter to be constructed. In the gutter evaluation device 100, the calculation unit 132 calculates the effective drainage cross-sectional area of ​​the vertical gutter and the effective drainage cross-sectional area of ​​the eaves gutter based on the vertical gutter size and the eaves gutter size acquired in step S102 of Fig. 7, for example. The calculation unit 132 calculates the drainage volume of the vertical gutter and the drainage volume of the eaves gutter by a predetermined calculation using the calculated effective drainage cross-sectional area of ​​the vertical gutter and the effective drainage cross-sectional area of ​​the eaves gutter, respectively. In this way, the drainage volume of the gutter to be constructed is obtained based on the drainage volume of the vertical gutter and the drainage volume of the eaves gutter. The calculation unit 132 may also calculate the amount of rainfall for comparison with the drainage amount of the rain gutter to be constructed calculated as described above. The calculation unit 132 calculates the amount of precipitation on the roof of the building on which the rain gutter to be constructed is to be provided, using the rainfall intensity and the target roof area in the basic information of the evaluation parameters acquired in step S102. In this case, the information output unit 133 may be capable of outputting drainage amount evaluation information that allows a comparison between the drainage amount of the rain gutter to be constructed, calculated by the calculation unit 132, and the amount of precipitation.

[0065] [Third Modification] The information output unit 133 may generate evaluation information including two or more evaluation results of the CO2 emission amount, the construction cost, and the amount of wastewater. In this case, the evaluation sheet presented based on the evaluation information shows two or more evaluation results included in the corresponding evaluation information.

[0066] [Fourth Variation] The construction cost evaluation sheet in Fig. 3 includes material costs and construction costs as the breakdown of the construction costs, but the construction cost evaluation sheet may be in a form in which either the material costs or the construction costs are shown. In this case, either the material costs or the construction costs may be calculated as the construction costs in step S108 or step S114 in Fig. 10.

[0067] [Fifth Modification] The calculation unit 132 may calculate the CO2 emissions, construction costs, etc. of the structural parts of the remaining members excluding predetermined members among the members constituting the rain gutter to be constructed. In this case, the calculated CO2 emissions, construction costs, etc. may be treated as the CO2 emissions and construction costs of the rain gutter to be constructed. In addition, certain components in the gutter may be replaced with other components to calculate the CO2 emissions, construction costs, etc. of the gutter. As an example, cranks for avoiding obstacles in a vertical gutter may be replaced with straight pipes to calculate the CO2 emissions, construction costs, etc. of the vertical gutter. This calculation method makes it possible to obtain a calculation result with a certain degree of reliability or higher, even though the calculation is simple.

[0068] [Sixth Modification] In addition to CO2, greenhouse gases include, for example, methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF6), etc. The greenhouse gas to be evaluated in this embodiment is not limited to CO2, and any one or more of the above gases may be selected. Furthermore, the gutter evaluation device 100 may be capable of calculating predetermined chemical substances and the like that are generated in association with the gutter other than greenhouse gases as an evaluation of the performance of the gutter.

[0069] [Seventh Variation] The gutter evaluation device 100 may be capable of calculating the logistics cost of a product as a gutter according to the input specifications, for example, by using information on the weight of the gutter to be constructed as an evaluation of the performance of the gutter. The gutter evaluation device 100 can obtain the weight of the gutter to be constructed based on, for example, the weight per unit quantity of components stored in a component database. In addition, the work efficiency of constructing rain gutters on site can be considered to depend on the weight of the components, since lighter components can be transported more efficiently and are easier to construct. Therefore, the rain gutter evaluation device 100 may be capable of calculating the work efficiency of constructing rain gutters according to the input specifications, using information on the weights of the components that make up the rain gutter to be constructed.

[0070] [Eighth Modification] For example, the functions of the gutter evaluation device 100 shown in Fig. 4 may be distributed among a plurality of devices. In this case, the distributed devices may be connected via a network, a signal line, or the like, so that the devices work together to realize the functions of the gutter evaluation device 100.

[0071] In addition, a program for realizing the functions of the rain gutter evaluation device 100 described above may be recorded on a computer-readable recording medium, and the program recorded on the recording medium may be read into a computer system and executed to perform the processing of the rain gutter evaluation device 100 described above. Here, "reading a program recorded on a recording medium into a computer system and executing it" includes installing the program into a computer system. The "computer system" here includes hardware such as an OS and peripheral devices. The "computer system" may also include a plurality of computer devices connected via a network including the Internet, a WAN, a LAN, a dedicated line, and other communication lines. The "computer-readable recording medium" refers to portable media such as a flexible disk, an optical magnetic disk, a ROM, a CD-ROM, and a storage device such as an HDD or an SDD built into a computer system. In this way, the recording medium storing the program may be a non-transient recording medium such as a CD-ROM. The recording medium also includes a recording medium provided inside or outside the computer system that can be accessed from a distribution server in order to distribute the program. The code of the program stored in the recording medium of the distribution server may be different from the code of the program in a format executable by a terminal device. That is, as long as it can be downloaded from a distribution server and installed in a form executable by a terminal device, the format in which it is stored in the distribution server does not matter. The program may be divided into multiple parts, downloaded at different times, and then combined on the terminal device, or each of the divided programs may be distributed by a different distribution server. Furthermore, the "computer-readable recording medium" includes a program that holds a program for a certain period of time, such as a volatile memory (RAM) inside a computer system that becomes a server or a client when a program is transmitted via a network. The program may also be a program for realizing part of the above-mentioned functions. Furthermore, the program may be a so-called difference file (difference program) that can realize the above-mentioned functions in combination with a program already recorded in the computer system.
