[0019] As shown in FIG. 1, the information processing system 1 includes a user terminal 10 and an information processing device 12. The user terminal 10 is a communication terminal device operated by a user. The user terminal 10 is capable of communicating with the information processing device 12 via a communication network NT, such as an IP (Internet Protocol) network. In the example of FIG. 1, the information processing system 1 includes multiple user terminals 10. The information processing system 1 may include only one user terminal 10. The user terminal 10 may be any terminal capable of communicating with the information processing device 12. The user terminal 10 may be a personal computer, a smart device such as a tablet terminal or a smartphone, or a mobile phone.

[0020] In the example of FIG. 2, the user terminal 10 is a personal computer. As shown in FIG. 2, the user terminal 10 has a computer main body 13, an operation unit 14, and a display unit 15. The operation unit 14 is a mouse and a keyboard connected to the computer main body 13. The display unit 15 is a screen of a display connected to the computer main body 13. For example, if the user terminal 10 is a smart device, the operation unit 14 and the display unit 15 are the screen of the smart device. The operation unit 14 may be a part that receives a user's voice and is operated by the received voice.

[0021] As shown in FIG. 4, the user terminal 10 has an input unit 30 and a suggestion unit 32. The input unit 30 receives regional information LI, which is received by a receiving unit 40 (described later). The input unit 30 sends the received regional information LI to the information processing device 12. When a predetermined input operation is performed by the user, the input unit 30 receives the input operation and transmits operation information based on the input operation to the information processing device 12. The operation information includes the regional information LI. The regional information LI is information about the region where the building Bd will be built, i.e., the construction site. The regional information LI includes information such as the name of the region where the building Bd will be built and the address of the region where the building Bd will be built. The name of the region where the building Bd will be built may be the name of a prefecture or the name of a city, ward, town, or village.

[0022] The input unit 30 has an operation unit 14 that is operated by the user. The function of the input unit 30 is realized, for example, when the user terminal 10 is provided with hardware such as the operation unit 14 and a processor such as a CPU (Central Processing Unit) of the user terminal 10 executes a program stored in a memory of the user terminal 10.

[0023] The proposal unit 32 outputs the proposed information PI output from the output unit 44, which will be described later, to the user. When the proposal unit 32 receives the proposed information PI transmitted from the information processing device 12, the proposal unit 32 outputs the proposed information PI by screen display or audio notification, etc. The proposal unit 32 has a display unit 15 that can output the proposed information PI by screen display. The proposal unit 32 displays a proposal screen PS (see FIG. 8 ) based on the proposed information PI transmitted from the information processing device 12 on the display unit 15. The proposal unit 32 may also have a speaker unit that can output the proposed information PI by audio notification. The function of the proposal unit 32 is realized, for example, when the user terminal 10 is provided with hardware having the display unit 15 and a processor, such as a CPU, of the user terminal 10 executes a program stored in a memory of the user terminal 10.

[0024] The hardware constituting the user terminal 10 includes the above-mentioned operation unit 14 and display unit 15. Although not shown in the figures, the hardware constituting the user terminal 10 includes, for example, a GPS receiver that receives a GPS (Global Positioning System) signal for identifying the location of the user terminal 10 via an antenna or the like. Other hardware configurations of the user terminal 10 are similar to the hardware configuration of the information processing device 12 described below, for example.

[0025] The information processing device 12 is a computer installed with an information processing program that executes the information processing method of this embodiment. The information processing program causes a computer to execute the information processing method of this embodiment. In this embodiment, the information processing device 12 is a server device that can communicate with the user terminal 10. The information processing device 12 is installed, for example, in a location different from the location of the user who uses the user terminal 10. The user operates the user terminal 10 to start the information processing program stored in the information processing device 12, which is a server device. The screen of the information processing program is displayed on a browser started on the display unit 15 of the user terminal 10. The information processing device 12 accepts information input from the user terminal 10, performs various processes based on the accepted information, and transmits the processing results to the user terminal 10.

[0026] As shown in FIG. 5, the information processing device 12 includes a control device 20, a communication device 22, and a storage device 24. The control device 20 includes a CPU 26 and a memory 28. The control device 20 functions as various functional units when the CPU 26 executes predetermined programs stored in the storage device 24, the memory 28, and the like. The communication device 22 is configured, for example, by a communication interface for communicating with devices external to the information processing device 12. The communication device 22 transmits and receives various types of information and various types of data to and from the user terminal 10. The storage device 24 is configured, for example, by a hard disk or the like. The storage device 24 stores various programs and information required for executing processing in the control device 20, information on processing results, and the like.

[0027] The information processing device 12 is realized using a device such as a dedicated or general-purpose server or computer. The information processing device 12 may be configured as a single device, or may be configured as a plurality of devices that can communicate with each other via a communication network NT. FIG. 5 merely illustrates a portion of the main hardware configuration of the information processing device 12. The information processing device 12 may also include other components that are generally included in a server device.

[0028] 4, the information processing device 12 includes a reception unit 40, a calculation unit 42, an output unit 44, and a storage unit 46. The reception unit 40 receives regional information LI related to the region in which the building Bd is to be built. The reception unit 40 receives information such as the regional information LI transmitted from the input unit 30 of the user terminal 10, and outputs the information to the calculation unit 42.

[0029] The calculation unit 42 calculates an environmental load evaluation value Ev that represents the environmental load for at least a portion of the building Bd, including the target components TM that constitute the building Bd, based on the regional information LI. In this embodiment, the calculation unit 42 calculates the environmental load evaluation value Ev that represents the environmental load for the target components TM that constitute the building Bd, i.e., the windows, based on information about the construction site of the building Bd. In this embodiment, the environmental load evaluation value Ev is the amount of greenhouse gas emissions or reduction caused by the operation of the building Bd. Greenhouse gases include carbon dioxide (CO2). Greenhouse gases emitted by the operation of the building Bd are called operational carbon. Operational carbon is emitted through energy use when people live in the building Bd.

[0030] The environmental impact assessment value Ev is not limited to operational carbon emissions or reductions, but may also be, for example, an assessment value from an LCA (Life Cycle Assessment), a method for comprehensively and quantitatively assessing environmental impacts throughout a life cycle. The LCA assessment value is calculated based on operational carbon emissions and greenhouse gas emissions resulting from the building Bd from its construction to its disposal, excluding its operation. The LCA assessment value is, for example, the total of operational carbon emissions and greenhouse gas emissions resulting from the building Bd from its construction to its disposal, excluding its operation. Greenhouse gases resulting from the building Bd from its construction to its disposal, excluding its operation, are called embodied carbon. Embodied carbon includes greenhouse gases emitted during the manufacturing of the target components, from raw material procurement to processing, transportation, construction, renovation, and disposal.

[0031] The calculation unit 42 calculates the heat balance Hb of heat that moves through the target component TM between the interior space of the building Bd and the exterior space of the building Bd based on the regional information LI. The calculation unit 42 calculates the heat balance Hb based on weather data acquired based on the regional information L1 and component information related to the target component TM. The calculation unit 42 calculates the environmental load evaluation value Ev based on the heat balance Hb.

[0032] The calculation unit 42 acquires meteorological data for the region where the building Bd is to be built based on the regional information LI. The meteorological data includes the average temperature and average solar radiation for the region where the building Bd is to be built. In this embodiment, the meteorological data acquired by the calculation unit 42 includes the average temperature and average solar radiation for the winter season in the region where the building Bd is to be built. The calculation unit 42 acquires the average solar radiation for each orientation of the exterior surface of the target component TM that faces the external space of the building Bd. The calculation unit 42 acquires the average solar radiation for the exterior surfaces facing each of the east-west, north-south, and south directions as meteorological data. In this embodiment, the calculation unit 42 acquires each average solar radiation when the inclination angle of each exterior surface with respect to the horizontal plane is 90°. The meteorological data may include the average temperature and average solar radiation for seasons other than winter, or may include the average temperature and average solar radiation for each month from January to December.

[0033] In this embodiment, the calculation unit 42 acquires weather data for the construction site indicated by the information included in the regional information LI, for example, from a known external database. Examples of known external databases include a database provided by the Automated Meteorological Data Acquisition System (AMeDAS) regional weather observation system in Japan, and a solar radiation database such as MONSOLA-20 provided by the New Energy and Industrial Technology Development Organization (NEDO). The calculation unit 42 may acquire weather data for each region stored in advance in the storage unit 46, etc., instead of acquiring weather data from an external database.

[0034] The calculation unit 42, for example, automatically selects or manually inputs information from the user a weather observation point that is closest to or appropriate for the construction site indicated by the information included in the regional information LI, and acquires weather data. The weather observation point may include, for example, an AMeDAS observation station. The calculation unit 42 may acquire elevation information for the construction site indicated by the information included in the regional information LI from a Geospatial Information Authority map provided by the Geospatial Information Authority of Japan, Ministry of Land, Infrastructure, Transport and Tourism of Japan. In this case, the calculation unit 42 may select a weather observation point based on the acquired elevation information. For example, even if a weather observation point is closest horizontally to the construction site, if the elevation of the weather observation point is significantly different from the elevation of the construction site, a weather observation point that is closer to the construction site than the weather observation point even if it is farther horizontally from the construction site may have weather conditions that are closer to the construction site. The calculation unit 42 can select a more appropriate weather observation point by selecting a weather observation point based on the elevation information for the construction site.

[0035] The calculation unit 42 acquires component information of the target component TM by referring to the storage unit 46. In this embodiment, the calculation unit 42 acquires the overall heat transmission coefficient of the window, the solar heat gain coefficient of the window, the area of ​​the window, and the like as component information of the window, which is the target component TM. The overall heat transmission coefficient of the window is calculated as the heat transfer coefficient of the window, which ... when the temperature difference between the internal space and the external space of the building Bd separated by the window is 1°C. 2 The solar heat gain coefficient is the ratio of the amount of solar radiation transmitted through the window to the amount of solar radiation irradiated onto the outer surface of the window from the external space of the building Bd. The calculation unit 42 obtains the overall unit heat transmission coefficient and the solar heat gain coefficient by referring to the window information table 46A stored in the memory unit 46.

[0036] As shown in FIG. 6, the window information table 46A stores the window's overall thermal transmittance and solar heat gain coefficient for each window type, linked to one another. The window type is determined by, for example, a combination of product series, frame material, opening / closing style, size of the opening into which the window is installed, and the type of window glass. Examples of window glass types include double-paned glass (two panes), triple-paned glass (three panes), low-emissivity (LOE) multi-pane, wired glass, and security glass. The window type "Window A PG solar gain type" stored in the window information table 46A indicates, for example, a product in the "Window A" series with a resin frame and double-paned (PG) glass with solar gain type glass. Similarly, "Window B TG solar shading type" indicates, for example, a product in the "Window B" series with an aluminum-resin composite frame and triple-paned (TG) glass with solar shading type glass. The window types may include window types in which the material of the window frame is a recycled material such as low-carbon aluminum profile "PremiAL (registered trademark)."

[0037] In this embodiment, the calculation unit 42 calculates, for each window type, the daily heat balance Hb of heat that moves through the window between the interior space of the building Bd and the exterior space of the building Bd. The heat balance Hb for a window is expressed by the following equation (1).

[0038] Hb = (solar radiation x window area x solar heat gain coefficient x α - temperature difference between inside and outside x window area x heat transmittance x β) ...Equation (1)

[0039] In equation (1), the amount of solar radiation is the average amount of solar radiation irradiated per hour on a unit area of ​​the target component TM, i.e., a window, during a certain period in a region obtained from the regional information LI. In equation (1), the indoor / outdoor temperature difference is the temperature difference between the interior space of the building Bd and the exterior space of the building Bd in the region obtained from the regional information LI. The indoor / outdoor temperature difference is calculated by subtracting the temperature of the exterior space of the building Bd, i.e., the outside air temperature, from the room temperature inside the building Bd. The calculation unit 42 calculates the indoor / outdoor temperature difference, for example, assuming the room temperature inside the building Bd to be 20°C. In equation (1), α and β are coefficients that take into account time and duration. In this embodiment, coefficient α is the average daily sunshine duration during the period for which the average amount of solar radiation is calculated. In this embodiment, coefficient β is the unit time of the calculated heat balance Hb. For example, when calculating the heat balance Hb per day, coefficient β is 24 hours. In equation (1), the window area is, for example, the area of ​​one window. The area of ​​the window is, for example, the same as or approximately the same as the opening area of ​​the opening in which the window is installed.

[0040] In this embodiment, the calculation unit 42 calculates the heat balance Hb in winter using formula (1). When calculating the heat balance Hb in winter, the calculation unit 42 uses the average amount of solar radiation irradiated per hour on a unit area of ​​the target component TM in winter in the region obtained from the regional information LI as the amount of solar radiation in formula (1). When calculating the heat balance Hb in winter, the calculation unit 42 uses the temperature difference between the interior space of the building Bd and the exterior space of the building Bd in winter in the region obtained from the regional information LI as the indoor / outdoor temperature difference in formula (1). When calculating the heat balance Hb in winter, the calculation unit 42 sets the room temperature to 20°C, for example, and the outdoor temperature to the average temperature in winter. When calculating the heat balance Hb in winter, the calculation unit 42 uses the hours of sunlight in one day in winter as the coefficient α in formula (1). The hours of sunlight in one day in winter is, for example, 10 hours. Winter refers to the period from December to February, for example. Because the amount of sunlight in a day varies from day to day even within the same season, the calculation unit 42 may obtain the amount of sunlight for each day based on meteorological data and calculate the heat balance Hb using a coefficient α that varies from day to day. In this case, the calculation unit 42 can calculate the heat balance Hb more accurately. Because the amount of sunlight varies from region to region even within the same season, the calculation unit 42 may obtain the amount of sunlight in that region based on meteorological data and use this as the coefficient α. In this case, the calculation unit 42 can calculate the heat balance Hb more accurately.

[0041] In equation (1), the total amount of solar radiation irradiating a window in a certain period of time in a certain region is calculated by multiplying the amount of solar radiation by the window area and coefficient α. Multiplying this total amount of solar radiation by the solar heat gain coefficient calculates the total amount of solar radiation passing through the window, which is the target component TM, and flowing into the interior space of the building Bd, i.e., the total amount of heat passing through the window and flowing into the interior space of the building Bd. Multiplying the temperature difference between the inside and outside of the building by the overall heat transfer coefficient and the window area in equation (1) calculates the amount of heat transferred per hour between the interior and exterior spaces of the building Bd through the window due to the temperature difference between the inside and outside of the building. Multiplying this amount of heat by coefficient β calculates the total amount of heat transferred between the interior and exterior spaces of the building Bd through the window due to the temperature difference between the inside and outside of the building per unit time of the calculated heat balance Hb. In equation (1), the amount of heat that moves through a window from the interior space of building Bd to the exterior space is a positive value, and the amount of heat that moves through a window from the exterior space of building Bd to the interior space is a negative value. The amount of heat that moves between the interior and exterior spaces of building Bd through a window due to the temperature difference between the interior and exterior is, for example, the amount of heat that flows out from the interior space of building Bd to the exterior space in winter. The amount of heat that moves between the interior and exterior spaces of building Bd through a window due to the temperature difference between the interior and exterior is, for example, the amount of heat that flows in from the exterior space of building Bd to the interior space in summer.

[0042] The heat balance Hb is calculated by subtracting the total amount of heat that moves between the interior space of building Bd and the exterior space through windows, i.e., the right-hand term on the right-hand side of equation (1), from the total amount of heat that flows into the interior space of building Bd through the windows, i.e., the left-hand term on the right-hand side of equation (1). In winter, because the outside temperature is lower than the room temperature inside building Bd, the right-hand term on the right-hand side of equation (1) is positive, and the amount of heat from the interior space of building Bd flows out through the windows to the exterior space. The heat balance Hb for a day in winter is calculated by subtracting the amount of heat that flows into the interior space of building Bd through the windows due to the temperature difference between inside and outside from the amount of heat that flows into the interior space of building Bd through the windows each day due to sunlight.

[0043] The calculation unit 42 calculates the environmental load evaluation value Ev based on the heat balance Hb and various information required to calculate the greenhouse gas reduction or emission amount stored in the memory unit 46. The various information required to calculate the greenhouse gas reduction or emission amount includes the energy consumption efficiency (COP: Coefficient of Performance) and carbon dioxide emission coefficient of the air conditioner that adjusts the temperature of the interior space of the building Bd. The energy consumption efficiency of the air conditioner is the value obtained by dividing the amount of heat required to maintain the temperature of the interior space of the building Bd at a certain set temperature by the power consumption. The energy consumption efficiency of the air conditioner is, for example, 4.0. The carbon dioxide emission coefficient is the value obtained by dividing the amount of carbon dioxide emitted when a certain amount of electricity is consumed by the certain amount of electricity. The carbon dioxide emission coefficient is, for example, 0.457 [kg-CO2 / kWh]. The environmental load evaluation value Ev is expressed, for example, by the following equation (2):

[0044] Ev = heat balance Hb ÷ energy consumption efficiency × carbon dioxide emission coefficient (2)

[0045] In equation (2), by dividing the heat balance Hb by the energy consumption efficiency, the power consumption required to cause the air conditioner to output energy equivalent to the energy of the heat balance Hb can be calculated. By multiplying this power consumption by the carbon dioxide emission coefficient, the amount of carbon dioxide emitted when this power consumption is consumed can be calculated. In this embodiment, this amount of carbon dioxide is the environmental load evaluation value Ev.

[0046] If the heat balance Hb is a positive value in winter, the amount of heat that flows into the interior space of building Bd through the windows per day is greater than the amount of heat that flows out through the windows to the exterior space of building Bd per day, so there is no need to operate the air conditioner in heating mode to cover the energy of heat balance Hb. If the heat balance Hb is a positive value in winter, the amount of time that the air conditioner operates in heating mode can be reduced, so the absolute value of the environmental impact assessment value Ev calculated based on the heat balance Hb corresponds to the amount of greenhouse gas reduction. The larger the heat balance Hb in winter, the less heating energy needs to be consumed by the air conditioner, resulting in a greater greenhouse gas reduction effect.

[0047] If the heat balance Hb is a negative value in winter, the energy of the heat balance Hb must be output into the building Bd by running the air conditioner in heating mode. If the heat balance Hb is a negative value in winter, the air conditioner will operate in heating mode for an increased amount of time, and the absolute value of the environmental load evaluation value Ev calculated based on the heat balance Hb corresponds to the amount of greenhouse gas emissions. In winter, if the environmental load evaluation value Ev is a positive value, that value corresponds to the amount of greenhouse gas reduction, and if the environmental load evaluation value Ev is a negative value, the absolute value of that value corresponds to the amount of greenhouse gas emissions.

[0048] The calculation unit 42 uses equations (1) and (2) to calculate the environmental load evaluation value Ev of windows for each window type in the region based on the region information LI received by the reception unit 40. The number of window types is not particularly limited. The calculation unit 42 outputs the calculated environmental load evaluation value Ev to the output unit 44.

[0049] The output unit 44 outputs proposal information PI for the target component TM based on the environmental load assessment value Ev. The proposal information PI is information that can be used as an index when a user selects a target component TM that constitutes the building Bd. The proposal information PI includes the environmental load assessment value Ev. The proposal information PI includes the ranking of the environmental load assessment values ​​Ev for each window type, and proposal information indicating how a window type should be selected based on the environmental load assessment value Ev. The output unit 44 transmits the proposal information PI to the user terminal 10.

[0050] The storage unit 46 stores information necessary for calculating the environmental load evaluation value Ev. The storage unit 46 stores the window information table 46A described above. The storage unit 46 stores various information related to windows, including window area, window performance, and window opening / closing mode, as well as various information necessary for calculating greenhouse gas reductions or emissions, such as energy consumption efficiency and carbon dioxide emission coefficient. The storage unit 46 is realized by a storage medium such as a RAM (Random Access Memory), a ROM (Read Only Memory), an HDD (Hard Disk Drive), or a flash memory. The storage unit 46 is configured by, for example, at least one of the storage device 24 and the memory 28.

[0051] Information processing using the information processing system 1 is performed, for example, according to the flowchart shown in FIG. 7. The processing performed by the information processing device 12 in FIG. 7 is processing performed by the information processing method of this embodiment. As shown in FIG. 7, information is input by the user to the user terminal 10 (step SP10). In step SP10, the user inputs regional information LI to the user terminal 10 via the input unit 30 of the user terminal 10. In step SP10, the user inputs the name of the construction site where the building Bd is to be constructed as regional information LI to the user terminal 10. The input regional information LI is transmitted from the input unit 30 to the information processing device 12.

[0052] The reception unit 40 of the information processing device 12 receives information transmitted from the input unit 30 (step SP12). In step SP12, the reception unit 40 receives the regional information LI transmitted from the input unit 30. The calculation unit 42 of the information processing device 12 acquires meteorological data for the construction site where the building Bd will be built, based on the regional information LI received by the reception unit 40 (step SP14). In step SP14, the calculation unit 42 acquires meteorological data for the construction site from an external database, such as AMeDAS. In step SP14, the calculation unit 42 selects an AMeDAS observation station close to the construction site based on the regional information LI and acquires meteorological data from the database of the selected AMeDAS observation station. If there are multiple AMeDAS observation stations close to the construction site, the information processing device 12 may transmit data related to the multiple AMeDAS observation stations to the user terminal 10. In this case, the user may select an AMeDAS observation station from which to acquire meteorological data via the input unit 30 of the user terminal 10, and the calculation unit 42 may acquire meteorological data from the database of the AMeDAS observation station selected by the user. If there are multiple AMeDAS observation stations near the construction site, the calculation unit 42 may automatically select an appropriate AMeDAS observation station whose weather conditions are similar to those of the construction site based on the above-mentioned altitude information, etc.

[0053] The calculation unit 42 calculates the heat balance Hb based on the weather data acquired in step SP14 and the component information related to the target component TM stored in the storage unit 46 (step SP16). In step SP16 of the present embodiment, the calculation unit 42 calculates the winter heat balance Hb for each of the plurality of window types using the above-described formula (1).

[0054] The calculation unit 42 calculates the environmental load evaluation value Ev (step SP18) based on the heat balance Hb calculated in step SP16 and the energy consumption efficiency and carbon dioxide emission coefficient stored in the storage unit 46. In step SP18 of this embodiment, the calculation unit 42 calculates the winter environmental load evaluation value Ev for each of the multiple window types using the above-mentioned formula (2).

[0055] The output unit 44 transmits the proposal information PI to the user terminal 10 based on the environmental load assessment value Ev calculated by the calculation unit 42 (step SP20). The proposal information PI transmitted by the output unit 44 to the user terminal 10 in step SP20 includes the environmental load assessment value Ev calculated in step SP18 and other information acquired based on the environmental load assessment value Ev. The other information acquired based on the environmental load assessment value Ev includes proposal information indicating the ranking of the environmental load assessment values ​​Ev for each window type and how a window type should be selected based on the environmental load assessment value Ev. The proposal unit 32 of the user terminal 10 displays the proposal information PI transmitted from the information processing device 12 in step SP20 (step SP22). In step SP22, the proposal unit 32 displays a proposal screen PS, as shown in FIG. 8, on the display unit 15 of the user terminal 10.

[0056] In the example of FIG. 8, the proposal screen PS displays the heat balance Hb per window for each window type, the environmental load assessment value Ev for each window type, and the proposal information PI for each orientation at the construction site. In the example of FIG. 8, the column with the orientation "south facing" is a column listing windows whose exterior faces south. Examples of windows whose orientation is "south facing" are windows WD1 and WD2 in FIG. 3. The column with the orientation "east-west facing" is a column listing windows whose exterior faces east or west. Examples of windows whose orientation is "east-west facing" are windows WD3, WD4, and WD5 in FIG. 3. The column with the orientation "north facing" is a column listing windows whose exterior faces north. The values ​​for each orientation in the example of FIG. 8 are values ​​for when the inclination angle of the exterior surface of each window with respect to the horizontal plane is 90°. Although the inclination angle θ1 of the outer surface WD5a of window WD5 relative to the horizontal plane is less than 90°, the user may use the proposed information PI proposed for the "east-west facing" on the proposal screen PS in Figure 8 as reference information when selecting the window type of window WD5.

[0057] In the example of FIG. 8, the proposal screen PS displays "daily heat balance" and "winter heat balance" as the heat balance Hb. "Daily heat balance" is the heat balance Hb for one day in winter. "Winter heat balance" is the heat balance Hb for the entire winter period. "Daily heat balance" is calculated by setting coefficient α in the above-mentioned formula (1) to the hours of sunshine in one day in winter and coefficient β to 24 hours. "Winter heat balance" is calculated by multiplying "daily heat balance" by the number of days in the winter period. "Winter heat balance" can also be calculated by setting coefficient α in the above-mentioned formula (1) to (hours of sunshine in one day in winter × number of days in the winter period) and coefficient β to (24 hours × number of days in the winter period).

[0058] In the example of FIG. 8, the environmental impact assessment value Ev is displayed as a "reference for CO2 reduction." In the example of FIG. 8, the proposal information PI listed for each window type is ranked PIa, indicating the order of lowest environmental impact. The ranking PIa is ranked in descending order of the environmental impact assessment value Ev. In the example of FIG. 8, the "Window B PG solar radiation gain type" on the south side has the highest environmental impact assessment value Ev, and the ranking PIa of this window is first. From this result, it can be seen that by selecting the "Window B PG solar radiation gain type" window type as the window on the south side of the building Bd to be built on the input construction site, the user can reduce the environmental impact associated with the windows of the building Bd compared to selecting other window types. For example, in the building Bd of FIG. 3, the user can effectively reduce the environmental impact of the building Bd by selecting the "Window B PG solar radiation gain type" window type as the windows WD1 and WD2 whose exterior surfaces WD1a and WD2a face south. In winter, the higher the window type with the higher environmental load evaluation value Ev is selected, the more the heating energy used in the building Bd can be reduced. In winter, heating energy accounts for a large proportion of the energy consumption in the building Bd. The more the window type with the higher environmental load evaluation value Ev is selected, the more the heating energy in winter can be reduced, and the more effectively the environmental load related to the building Bd can be reduced.

[0059] In the example of FIG. 8 , the proposal screen PS displays proposal information PIb as proposal information indicating how a window type should be selected based on the environmental load evaluation value Ev. The proposal information PIb is, for example, information indicating indicators for a user when selecting a window type for each orientation. The proposal information PIb includes, for example, information such as: For south-facing windows, it is better to select windows with a high heat balance Hb; and, for windows facing orientations other than south, it is better to select windows that take summer into consideration. For example, in summer, east- and west-facing windows receive more solar radiation, which tends to increase the temperature inside building Bd, potentially increasing the amount of time the air conditioner needs to operate in cooling mode. For east- and west-facing windows, selecting windows with a low winter environmental load evaluation value Ev may potentially reduce the environmental load caused by building Bd throughout the year, rather than simply selecting windows with a high winter environmental load evaluation value Ev. In the example of FIG. 8 , the proposal screen PS displays calculation conditions for calculating the proposal information PI. The calculation conditions include, for example, information about the database that the calculation unit 42 refers to, and information about the various parameters in the above-mentioned equations (1) and (2).

[0060] At least some of the components constituting the information processing system 1 are realized by, for example, a processor such as a CPU executing an information processing program stored in the storage unit 46. At least some of the functions of the information processing system 1 described above may be realized by hardware including circuit units such as, for example, a large scale integration (LSI), an application specific integrated circuit (ASIC), a field-programmable gate array (FPGA), and a graphics processing unit (GPU), or may be realized by a combination of software and hardware.

[0061] The information processing device 12 includes a receiving unit 40 that receives regional information LI related to the region where the building Bd will be built, a calculation unit 42 that calculates, based on the regional information LI, an environmental load assessment value Ev that represents the environmental load of at least a portion of the building Bd, including target components TM that constitute the building Bd, and an output unit 44 that outputs proposal information PI for the target components TM based on the environmental load assessment value Ev. By calculating the environmental load assessment value Ev based on the regional information LI and outputting the proposal information PI for the target components TM based on the environmental load assessment value Ev, the information processing device 12 can propose to the user target components TM that can reduce the environmental load in the region where the building Bd will be built. Based on the proposal information PI proposed by the information processing device 12, the user can select target components TM that are suitable for the region where the building Bd will be built, thereby effectively reducing the environmental load caused by the building Bd.

[0062] The information processing method of this embodiment includes receiving regional information LI related to the region where the building Bd is to be built, calculating an environmental load assessment value Ev representing the environmental load of at least a portion of the building Bd, including target components TM constituting the building Bd, based on the regional information LI, and outputting proposal information PI about the target components TM based on the environmental load assessment value Ev. As with the information processing device 12 described above, the information processing method of this embodiment can propose to a user target components TM that can reduce the environmental load in the region where the building Bd is to be built.

[0063] In this embodiment, the target component TM is a component having an outer surface facing the exterior space of the building Bd. In the information processing device 12, the calculation unit 42 calculates a heat balance Hb of heat passing through the target component TM between the interior space of the building Bd and the exterior space of the building Bd based on the area information LI, and calculates an environmental load assessment value Ev based on the heat balance Hb. In other words, the information processing method of this embodiment includes calculating a heat balance Hb of heat passing through the target component TM having an outer surface facing the exterior space of the building Bd between the interior space of the building Bd and the exterior space of the building Bd based on the area information LI, and calculating an environmental load assessment value Ev based on the heat balance Hb. The calculation unit 42 converts the heat balance Hb into greenhouse gas emissions, thereby calculating the greenhouse gas reduction amount as the environmental load assessment value Ev. By obtaining proposal information PI based on this environmental load assessment value Ev, the user can select a target component TM that can more effectively reduce environmental load.

[0064] In the information processing device 12, the calculation unit 42 acquires regional weather data based on the regional information LI, and calculates the heat balance Hb based on the weather data and component information related to the target component TM. In other words, the information processing method in this embodiment includes acquiring regional weather data based on the regional information LI, and calculating the heat balance Hb based on the weather data and component information related to the target component TM. By calculating the heat balance Hb based on the weather data acquired based on the regional information LI and the component information related to the target component TM, the calculation unit 42 can more accurately calculate the heat balance Hb in the region where the building Bd is built.

[0065] The weather data acquired by the calculation unit 42 includes information on the orientation of the outer surface of the target component TM. Because the weather data includes information on the orientation of the outer surface of the target component TM, the calculation unit 42 can calculate the heat balance Hb for each orientation of the outer surface of the target component TM. In the example of FIG. 8 described above, the calculation unit 42 calculates the heat balance Hb of the target component TM for each of the following cases: when the outer surface of the target component TM is a south-facing surface facing south, when the outer surface of the target component TM is an east-west facing surface facing either east or west, and when the outer surface of the target component TM is a north-facing surface facing north. By acquiring the proposal information PI acquired based on the heat balance Hb for each orientation, the user can select a target component TM suitable for each orientation of the outer surface of the target component TM that constitutes the building Bd.

[0066] The target components TM include components to be attached to openings in the building Bd. Components to be attached to openings include windows and doors. The information processing device 12 outputs suggested information PI about the target components TM, which are components to be attached to openings, so that the user can select windows and doors suitable for the area where the building Bd is to be built. In this embodiment, the user can use the information processing system 1 to select window types suitable for each of the windows WD1 to WD5 of the building Bd shown in FIG. 3.

[0067] The proposal information PI includes an environmental load assessment value Ev of the target component TM. Since the information processing device 12 can output the environmental load assessment value Ev of the target component TM as the proposal information PI, the user can suitably select a component type with a small environmental load as the target component TM based on the proposal information PI.

[0068] The information processing system 1 includes an information processing device 12 and a user terminal 10 capable of communicating with the information processing device 12. The information processing device 12 is a server device capable of communicating with the user terminal 10. The user terminal 10 has an input unit 30 to which local information LI accepted by a accepting unit 40 is input, and a proposing unit 32 that outputs suggested information PI output from an output unit 44 to the user. A user can easily use the information processing device 12 by communicating with the user terminal 10. By inputting the local information LI into the user terminal 10 via the input unit 30, the user can easily input the local information LI into the information processing device 12, which is a server device capable of communicating with the user terminal 10. The suggested information PI sent from the information processing device 12, which is a server device, to the user terminal 10 is output by the proposing unit 32, allowing the user to easily know the suggested information PI. The user terminal 10 has an input unit 30 through which the user inputs regional information LI and a proposal unit 32 through which the user acquires proposed information PI, and is therefore a terminal that performs the functions necessary to enable the user to select target components TM of a building Bd that are suitable for the region based on the proposed information PI. The information processing system 1 is a system that can be used via the user terminal 10, and the effects of making it easy for the user to acquire proposed information PI and allowing the user to select target components TM of a building Bd that are suitable for the region are effects that are realized via the user terminal 10.

[0069] Although the embodiments of the present disclosure have been described above, the present disclosure is not limited to the configurations of the above-described embodiments, and the following configurations and methods may also be adopted.

[0070] The receiving unit 40 of the information processing device 12 may receive design information for the building Bd. The design information is information about the components that make up the building Bd. The design information includes the type of exterior wall material that makes up the building Bd, the building area of ​​the building Bd, the number of windows the building Bd has, and the like. When the receiving unit 40 receives the design information for the building Bd, the calculation unit 42 calculates an environmental load assessment value Ev based on the design information. In other words, in this case, the information processing method includes receiving the design information for the building Bd and calculating the environmental load assessment value Ev based on the design information. By the calculation unit 42 calculating the environmental load assessment value Ev based on the design information for the building Bd, the information processing device 12 can propose to the user proposal information PI that is more suitable for the building Bd. The design information for the building Bd may be input by the user via the input unit 30 or may be stored in advance in the information processing device 12.

[0071] The proposal information PI may include an environmental load assessment value Ev for the entire building Bd. The environmental load assessment value Ev for the entire building Bd is calculated, for example, based on a heat balance Hb, which is the difference between the amount of heat flowing into the interior space of the building Bd through all windows and exterior walls of the building Bd and the amount of heat flowing out to the exterior space of the building Bd through all windows and exterior walls of the building Bd. When the calculation unit 42 calculates the environmental load assessment value Ev for the entire building Bd, the reception unit 40 receives the design information for the building Bd described above. The calculation unit 42 calculates the heat balance Hb for the entire building Bd based on the design information for the building Bd and the regional information LI, and then calculates the environmental load assessment value Ev for the entire building Bd based on the heat balance Hb. The heat balance Hb for the entire building Bd may be the heat balance Hb for a specific season, such as winter, or the heat balance Hb for the entire year.

[0072] The "environmental load assessment value Ev of the entire building Bd" may be any value as long as it is a comprehensive environmental load assessment value Ev of the building Bd calculated taking into account the environmental loads of all target components TM included in the building Bd. The "environmental load assessment value Ev of the entire building Bd" may be the total sum of the environmental load assessment values ​​Ev of all components that constitute the building Bd and have an exterior surface facing the exterior space of the building Bd, or the total sum of the environmental load assessment values ​​Ev of all target components TM included in the building Bd. If the target components TM are windows, the "environmental load assessment value Ev of the entire building Bd" may be, for example, a value equivalent to the total sum of the environmental load assessment values ​​Ev of all windows included in the building Bd, or a value equivalent to the total sum of the environmental load assessment values ​​Ev of all windows included in the building Bd plus the environmental load assessment values ​​Ev of components other than windows, such as exterior walls, that have an exterior surface facing the exterior space of the building Bd. The "environmental load evaluation value Ev of the entire building Bd" may be a value calculated using formula (2) with the total heat balance of heat moving between the internal space and the external space of the building Bd as the heat balance Hb. The "environmental load evaluation value Ev of the entire building Bd" may be a value calculated using formula (2) with the total value of the heat balance of all target components TM included in the building Bd as the heat balance Hb.

[0073] When the proposal information PI includes an environmental load assessment value Ev of the entire building Bd, the proposal screen PS displayed on the user terminal 10 includes, for example, a display such as that shown in FIG. 9. In the example of FIG. 9, building patterns are selection patterns for the target components TM that constitute the building Bd. In FIG. 9, building patterns 1, 2, and 3 are shown. The user can confirm the combination of target components TM included in each building pattern by, for example, selecting the column for each building pattern on the proposal screen PS. The proposal screen PS shown in the example of FIG. 9 displays, for each of multiple building patterns, the heat balance Hb of the entire building Bd in winter, the environmental load assessment value Ev of the entire building Bd in winter, and the ranking PIa for winter. The user can select which building pattern is preferable as a pattern to select as the target components TM that constitute the building Bd based on the environmental load assessment value Ev of the entire building Bd and the ranking PIa. By including the environmental load evaluation value Ev of the entire building Bd in the proposal information PI, the user can select components that are suitable for the area as target components TM that make up the building Bd, while taking into consideration the load that the entire building Bd places on the environment.

[0074] The weather data acquired by the calculation unit 42 may include information on the inclination angle of the outer surface of the target component TM relative to the horizontal plane. The inclination angles relative to the horizontal plane are, for example, inclination angles θ1, θ2, and θ3 shown in FIG. 3 . When the weather data includes information on the inclination angles, the calculation unit 42 can calculate the environmental load evaluation value Ev for each target component TM whose outer surface is inclined at different inclination angles relative to the horizontal plane. For example, the calculation unit 42 can calculate the environmental load evaluation value Ev for each window type for each orientation when the inclination angle is θ1 shown in FIG. 3 and when the inclination angles are θ2 and θ3 shown in FIG. 3 . Based on the environmental load evaluation value Ev for the inclination angle θ1, the user can select a window that can reduce the environmental load appropriate for the region, such as window WD5 shown in FIG. 3 . Based on the environmental load evaluation value Ev for the inclination angles θ2 and θ3, the user can select a window that can reduce the environmental load appropriate for the region, such as windows WD1, WD2, WD3, and WD4 shown in FIG. 3 . The inclination angle is not particularly limited. The inclination angle of the outer surface of a skylight attached to a roof that is aligned along a horizontal plane is, for example, 0°. For a target component TM with an outer surface inclination angle of 0°, the outer surface does not face any of the four directions (east, west, north, south), so various information for each direction is not calculated, and for example, only one type of information is calculated.

[0075] The method by which the calculation unit 42 calculates the heat balance Hb is not limited to the above-described formula (1) and is not particularly limited. The window area used in formula (1) is not limited to the area of ​​a single window, but may be the total area of ​​multiple windows included in the building Bd, or the total area of ​​all windows included in the building Bd. The calculation unit 42 may calculate the total amount of heat balance Hb of all windows included in the building Bd and an environmental load evaluation value Ev based on the total amount of heat balance Hb based on formula (1) using the total area of ​​all windows included in the building Bd. In this case, the information processing device 12 may output window recommendation information PI suitable for the region based on the environmental load evaluation value Ev based on the total amount of heat balance Hb.

[0076] The values ​​of the coefficients α and β in formula (1) can be changed as appropriate, and may be values ​​that vary depending on the hours of sunshine at the construction site and the period of use of heating and cooling equipment at the construction site. The coefficients α and β may be determined based on meteorological data such as the daily average temperature and hourly temperature data obtained from the database of AMeDAS observation stations.

[0077] The method by which the calculation unit 42 calculates the environmental load evaluation value Ev is not limited to the above-described formula (2) and is not particularly limited. The values ​​of the energy consumption efficiency and the carbon dioxide emission coefficient in formula (2) can be changed as appropriate. The calculation unit 42 may calculate the heat balance Hb for a season other than winter, such as summer, and calculate the environmental load evaluation value Ev for the season other than winter based on the heat balance Hb. In this case, the output unit 44 of the information processing device 12 may output the proposal information PI based on the environmental load evaluation value Ev for the season other than winter. The calculation unit 42 can also calculate the heat balance Hb of the window in summer using formula (1), and can also calculate the environmental load evaluation value Ev in summer using formula (2). If the heat balance Hb in summer calculated based on formula (1) is a positive value, it becomes necessary to operate the air conditioner in cooling mode to remove the heat amount of the heat balance Hb from the interior space of the building Bd, which increases greenhouse gas emissions and increases the environmental load evaluation value Ev. When the environmental load evaluation value Ev for summer is calculated based on equations (1) and (2), the smaller the environmental load evaluation value Ev, the smaller the load on the environment. When the environmental load evaluation value Ev is a negative value, the absolute value of the environmental load evaluation value Ev represents the amount of greenhouse gas reduction. The calculation unit 42 may use an equation for calculating the heat balance Hb for summer that reverses the positive and negative signs of the result from equation (1). When this equation is used, the heat flowing into the interior space of the building Bd becomes a negative value, and the heat flowing out to the exterior space of the building Bd becomes a positive value. When the heat balance Hb for summer is calculated using this equation, when the heat balance Hb is a positive value, the environmental load evaluation value Ev calculated using equation (2) represents the amount of greenhouse gas reduction, and the larger the environmental load evaluation value Ev, the smaller the load on the environment. The air conditioner having the energy consumption efficiency used in the above formula (2) may be any equipment capable of adjusting the temperature of the interior space of the building Bd, and is not limited to an air conditioner, but may also be a heating equipment such as a stove.

[0078] The building Bd targeted by the information processing device 12 may be any type of building, such as a house, an apartment building, or a building. The information processing device 12 may include a determination unit that determines the optimal target component TM in the area where the building Bd is to be built based on the calculation result of the calculation unit 42.

[0079] The object for which the environmental load evaluation value Ev is calculated is not particularly limited as long as it is at least a part of the building Bd that includes the target component TM. The object for which the environmental load evaluation value Ev is calculated may be the entire building Bd as described above, or may be a part that includes the target component TM and another part of the building Bd.

[0080] As described above, the environmental load evaluation value Ev may be an LCA evaluation value. In this case, the information processing device 12 can provide the user with proposal information PI based on the environmental load evaluation value Ev, which comprehensively evaluates the environmental load throughout the entire life cycle of the target, including not only operational carbon generated during occupancy but also embodied carbon related to at least a portion of the building Bd. By obtaining the proposal information PI, the user can select target components TM that can further reduce the environmental load in the area where the building Bd will be built. The information processing device 12 may have a function to determine whether the construction site of the building Bd is an area heavily affected by operational carbon or embodied carbon, and, based on the determination result, determine target components TM that can comprehensively reduce the environmental load throughout the entire life cycle. The environmental load evaluation value Ev is not particularly limited as long as it is a value representing the environmental load, and may be a value other than greenhouse gas emissions. For example, if the environmental load evaluation value Ev is an evaluation value that includes embodied carbon, and the proposed target component TM includes a component that uses recycled materials such as "PremiAL (registered trademark)" as a constituent material, the user can select the target component TM taking into account the amount of embodied carbon that would be reduced if recycled materials were used.

[0081] The proposal screen PS on which the proposal information PI is displayed is not limited to the examples shown in Figures 8 and 9, and may be any screen. The proposal screen PS may display only the types of target components TM that have the lowest environmental load based on the environmental load evaluation value Ev. For example, the proposal screen PS in Figure 8 may display only the proposal information PI for only some of the top-ranked window types for each orientation.

[0082] The information processing device 12 may be a device that the user can use without using the user terminal 10. In this case, the information processing device 12 includes an input unit into which the user can input various information, and a proposal unit that outputs proposal information PI to the user. In this case, the function of the input unit may be included in the reception unit 40, or may be included in a functional unit other than the reception unit 40. In this case, the function of the proposal unit may be included in the output unit 44, or may be included in a functional unit other than the output unit 44.

[0083] The target component TM for which the proposal information PI is output may be any component constituting the building Bd. The target component TM may be the door D shown in FIG. 3, at least a portion of the roof R, such as the first roof section R1 and the second roof section R2, or an exterior wall, such as the east wall WE, the west wall WW, the south wall WS, or the north wall WN. When the target component TM is an exterior wall, the calculation unit 42 can calculate the heat balance Hb that moves between the interior and exterior spaces of the building Bd via the exterior wall by replacing the window area in the above-described formula (1) with the area of ​​the exterior wall and replacing the solar heat gain coefficient in formula (1) with a value equivalent to the solar heat gain coefficient for the exterior wall. The value equivalent to the solar heat gain coefficient for the exterior wall is, for example, the value obtained by multiplying the overall heat transmission coefficient of the exterior wall by a predetermined coefficient.
