Description

[Technical Field]

[0001] The present invention relates to an information processing system, an information processing method, and a program. [Background technology]

[0002] Building renewal, renovation, and use for the purpose of promoting the rationalization of energy use and the shift to non-fossil energy are encouraged. Buildings that meet these objectives are called "energy-saving buildings" (for example, commercial buildings that incorporate energy-saving technologies) or "ZEBs (Net Zero Energy Buildings)." To assess whether a building meets the above objectives (i.e., whether it is an "energy-saving building" or "ZEB"), the effectiveness of reduced energy and utility costs ("EB (Energy Benefits)") is often evaluated. In the following explanation, when referring to "energy-saving buildings" or "ZEBs" collectively, they may be referred to simply as "ZEBs." [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-332165 Summary of the Invention [Problem to be solved by the invention]

[0004] In these "ZEB" evaluation methods, emphasis has been placed on the effects ("EB") of the reduction in energy and utility costs, and no attention has been paid to effects other than the above-mentioned energy and utility cost reduction effects ("EB") (hereinafter referred to as "NEBs (Non-Energy Benefits)"). As a result, if only a portion of the effects obtained by "ZEB" is evaluated, the effects of building renovations or the effects of using new buildings may be underestimated, which may affect policy decisions regarding building renovations and new procurement. In the following explanation, building renovations include new procurement.

[0005] The present invention has been made in consideration of the above circumstances, and aims to provide an information processing system, an information processing method, and a program that can more appropriately evaluate the effects of building renewal and renovation. [Means for solving the problem]

[0006] (1) In order to solve the above problem, one aspect of the present invention is an information processing system that includes a processing unit that derives the degree of secondary effects that can be obtained from the renewal or renovation of a building or building equipment based on the evaluation results of a group of evaluation items other than reductions in energy usage and utility costs, among the effects that can be expected from the renewal or renovation of the building or building equipment. (2) The secondary effects of the above information processing system include the effects of the evaluation items identified from the evaluation items related to "health promotion," "improvement of intellectual productivity," "reduction of maintenance costs," "reduction of carbon taxes, etc.", "business continuity planning and risk management," and "reduction of employee turnover rate." (3) In the above information processing system, the processing unit performs an evaluation regarding the "improvement of intellectual productivity" and derives the effects of evaluation items regarding the "improvement of intellectual productivity." (4) In the above information processing system, the processing unit derives the effects of health promotion after the renewal and renovation based on the stress sensitivity responses of the target group using the building, the time spent in the building (impact rate), and the value obtained from the work of the target group, and includes the effects of health promotion in the secondary effects. (5) In the above information processing system, the processing unit derives the effects of health promotion after the renewal and renovation using the amount of health insurance payments made by the target group using the building and the time spent in the building, and includes the effects in the secondary effects. (6) In the above information processing system, the processing unit derives the effect of the carbon tax reduction based on the amount of carbon dioxide emissions resulting from the implementation of measures to reduce carbon dioxide emissions or energy usage, and includes this in the secondary effects when evaluating the reduction of the carbon tax. (7) In the above information processing system, the processing unit derives the effects of the business continuity plan and the risk management from amounts based on the annual electricity consumption, the unit cost of damage caused by power outage, and the percentage of time during which the power supply is outage per year, and includes these in the secondary effects when evaluating the business continuity plan and the risk management. (8) In the above-mentioned information processing system, the processing unit derives the effect of the evaluation of the business continuity plan and the risk management from an amount based on the number of hours that business shutdown was avoided by power supply from the emergency power supply equipment during a power outage and the amount of profit per unit time, and includes this in the secondary effect. (9) In the above information processing system, the processing unit derives the effect of the evaluation of the reduction in the turnover rate from an amount based on the amount of reduction in costs required to acquire mid-career recruits due to the reduction in the number of employees leaving the company as a result of the implementation of the renewal and renovation, the amount of reduction in training costs for the mid-career recruits, and the amount of reduction in costs required to promote the employment of the mid-career recruits due to increased awareness of the implementation of the renewal and renovation, and includes this effect in the secondary effects. (10) The information processing system indicates the degree of the secondary effect, the first effect related to the evaluation item of “assessment of energy use reduction (through energy conservation and energy generation evaluated by ZEB (Net Zero Energy Building))” expected by updating and renovating the building or the equipment, and the expected second effect related to other evaluation items among the evaluation items (ZEB-related items) in addition to the first effect. (11) An information processing method according to one embodiment of the present invention is an information processing method that includes a process of deriving the degree of secondary effects that can be obtained from the renewal or renovation of a building or building equipment based on the evaluation results of a group of evaluation items other than reduction in energy usage and reduction in utility costs, among the effects that can be expected from the renewal or renovation of the building or building equipment. (12) One aspect of the program of the present invention is a program for causing a computer to derive the degree of secondary effects to be obtained from the renewal or renovation of a building or building equipment based on the evaluation results of a group of evaluation items other than reduction in energy usage and reduction in utility costs, among the effects expected from the renewal or renovation of the building or building equipment. [Effects of the Invention]

[0007] According to each aspect of the present invention, the effects of building renovation and refurbishment can be more appropriately evaluated. [Brief explanation of the drawings]

[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In each drawing, the same or corresponding components are designated by the same reference numerals and the description thereof will be omitted as appropriate. In the embodiment, "renewal and renovation" includes either renewal or renovation of the target building. This "update and renovation of the target building" includes either the update or renovation aimed at achieving so-called "ZEB." "Update and renovation" aimed at achieving "ZEB" may be simply referred to as "update and renovation." Note that "building update" in the embodiments may also include the use of a new "ZEB."

[0010] 1 is an explanatory diagram showing an overview of an information processing system according to an embodiment of the present invention. The information processing system 1 shown in the figure derives the degree of secondary effects obtained from the renovation or remodeling of a building or building facilities based on the evaluation results of a group of evaluation items other than reductions in energy usage and utility costs, among the effects expected from the renovation or remodeling of the building or building facilities. The secondary effects mentioned above include some or all of the effects of "health promotion," "improvement of intellectual productivity," "reduced maintenance costs," "reduction of carbon taxes, etc.", "business continuity planning and risk management," "reduced employee turnover," etc. The above are just examples, and the effects may be increased or decreased as appropriate without being limited to these, or may include effects resulting from more specifically developed processing. For example, the information processing system 1 may perform an evaluation regarding "improvement of intellectual productivity" and derive the effect of the evaluation item regarding "improvement of intellectual productivity."

[0011] The configuration of the information processing system 1 shown in the figure will be described below. The information processing system 1 includes a processing device 100 . The processing device 100 is an example of a so-called computer. The processing device 100 can communicate with an external server device or the like via a communication line. For example, the processing device 100 includes an information acquisition unit 10, an initial data setting processing unit 20, an arithmetic processing unit 30, a display unit 40, a communication processing unit 50, and a storage unit .

[0012] The information acquisition unit 10 receives various data supplied from the outside and stores the received various data in the storage unit 70 according to the type of the various data. The information acquisition unit 10 acquires correction information from the outside and adds the acquired information to the data in the storage unit 70 and stores it as information to be used for various processes by the calculation processing unit 30 etc.

[0013] The initial data setting processor 20 sets initial data for various data required for various processes by the information processing system 1, and stores the data in the storage unit . This initial data may include, or consist of, data used for various processes for evaluation such as "health promotion," "improvement of intellectual productivity," "reduced maintenance costs," "improved interior and exterior aesthetics," "reduced carbon taxes, etc.", "obtaining environmental certifications and ratings," "business continuity planning and risk management," "reduced turnover," "internal education," "fundraising," "advertising and promotion," and "improved real estate value."

[0014] The calculation processing unit 30 may perform various processes for evaluation, such as "health promotion," "improvement of intellectual productivity," "reduced maintenance costs," "improved interior and exterior aesthetics," "reduced carbon tax, etc.", "obtaining environmental certifications and ratings," "business continuity planning and risk management," "reduced turnover rate," "internal education," "fund raising," "advertising and public relations," and "improved real estate value," and may be configured to perform some of these processes. For example, the arithmetic processing unit 30 switches between two modes: an initial setting mode for executing initial settings required for the various processes described above, and an evaluation processing mode for various evaluations performed after the initial setting mode. The processes executed by the arithmetic processing unit 30 are roughly classified in advance according to the results of switching between these modes. In the initial setting mode, the calculation processing unit 30 identifies information necessary for the processing device 100 to function and adds it to the storage unit 70. If this information is not dependent on the user, it can be preset as a fixed value. For example, the data may include data such as coefficients and thresholds used in each process in the evaluation processing mode. The calculation processing unit 30 acquires individual information required for the various processes described above and generates data for processing in the evaluation processing mode based on this information. For example, the generated data may include data such as coefficients and thresholds that vary depending on the user. In the evaluation processing mode, the calculation processing unit 30 refers to the memory unit 70 and performs each evaluation process using the data generated in the initial setting mode, the data registered by the information acquisition unit 10, and the data generated by the calculation processing unit 30 itself. The arithmetic processing unit 30 displays the data collected by the information acquisition unit 10 and the results of each evaluation process in the evaluation processing mode on the display unit 40 or the like.

[0015] The communication processing unit 50 communicates with an external device. For example, the external device includes a terminal device, a server, etc. that requests the information processing system 1 to perform a desired process. The display unit 40 displays the image information generated by the above-mentioned display processing units. For example, the display unit 40 may be configured to include an LCD or the like.

[0016] The storage unit 70 includes an initial data storage unit 71 and an evaluation data storage unit 72 . The initial data storage unit 71 stores various data collected from the outside as initial data.

[0017] For example, the initial data storage unit 71 stores the set initial data as is without processing it. When representative values ​​are generated from the initial data stored without processing it, the initial data storage unit 71 may also store the respective representative values.

[0018] The evaluation data storage unit 72 stores, for example, the original data that is the target of the evaluation process and the output data that indicates the result of the evaluation process in association with each other. For example, the data stored in the evaluation data storage unit 72 includes data on the results of processing related to various evaluation items such as "health promotion," "improvement of intellectual productivity," "reduction in maintenance costs," "reduction in carbon taxes, etc.", "business continuity and risk management," and "reduction in employee turnover rate."

[0019] Next, the processing of the information processing system 1 configured as above will be explained in order.

[0020] In the following embodiment, an example will be described in which a user operates the processing device 100 to obtain the application program from the server device 200 and use it.

[0021] (mode) The processing modes include an "initial data registration mode" and an "evaluation processing mode." The "initial data registration mode" is a mode in which processing for registering initial data is executed. The "evaluation processing mode" is a mode in which evaluation processing for calculating NEB is executed. The "evaluation processing mode" of this embodiment includes a "first evaluation processing mode" and a "second evaluation processing mode." The "first evaluation processing mode" is for carrying out evaluation processing for the planning and planning stage before updating and renovating. The "second evaluation processing mode" is for carrying out evaluation processing for the evaluation stage after updating and renovating. The "first evaluation processing mode" and the "second evaluation processing mode" differ in the applicable evaluation items and the types of input variables for the evaluation processing.

[0022] (NEBs classification) The effects of building renovations and refurbishments include the effect of converting buildings into energy-efficient buildings with the aim of promoting the rationalization of energy use and the shift to non-fossil energy sources, and other effects such as secondary, indirect and synergistic effects that accompany renovations to energy-efficient buildings can also be expected. The effects of building renovation and renewal include, for example, "health promotion," "improved intellectual productivity," "reduced maintenance costs," "improved interior and exterior aesthetics," "reduced carbon taxes, etc.," "obtaining environmental certifications and ratings," "business continuity planning and risk management," "reduced turnover," "internal awareness," "fundraising," "advertising," and "improved real estate value." These are allocated to the above secondary, indirect, and synergistic effects. Secondary effects include "health promotion," "improved intellectual productivity," "reduced maintenance costs," "improved interior and exterior aesthetics," "reduced carbon taxes, etc.", "obtaining environmental certifications and ratings," and "business continuity planning and risk management." Indirect effects include "reduced turnover rate," "internal awareness," "fundraising," and "advertising and promotion." Synergistic effects include "increased real estate value."

[0023] (Summary of evaluation items and evaluation methods) The following are examples of evaluation items to be evaluated in the evaluation process. Evaluation items in this embodiment may include "health promotion," "improvement of intellectual productivity," "reduced maintenance costs," "improved interior and exterior aesthetics," "reduction of carbon taxes, etc.", "obtaining environmental certifications and ratings," "business continuity planning and risk management," "reduced turnover," "internal education," "fundraising," "advertising and promotion," and "improved real estate value."

[0024] The "Health Promotion" section evaluates the health status of building occupants. For example, it is expected that the office environment will improve as a result of building renovations. If users become mentally and physically healthier as a result, it is expected that performance declines due to poor health will be resolved and absenteeism will decrease. The effects of such changes in health status will be quantified.

[0025] The "Improvement of Intellectual Productivity" category evaluates the productivity of the building's users' work. For example, it is expected that the office environment will be improved in the same way as above, which will result in improved intellectual productivity and increased work efficiency for users. "Maintenance cost reduction" evaluates the amount of reduction in costs required for maintenance and inspection of buildings and their building facilities. For example, when a building is renovated or remodeled, the building and its building equipment are updated or renovated, and it is expected that they will become more energy-efficient and energy-generating than before. As a result, the usage time of building equipment such as air conditioning equipment and lighting equipment will decrease, and the costs required for maintenance of these equipment are expected to decrease. Furthermore, if solar power generation equipment is installed with the aim of achieving ZEB, the costs required for its maintenance will be added.

[0026] The "improvement of interior and exterior beauty" category evaluates the interior and exterior of the building. For example, by updating or renovating the building, it is expected that users and those around the building will have a different impression from the previous building.

[0027] The "Carbon tax reduction, etc." item is an evaluation item regarding the amount of CO2 emission reduction. For example, if a building is renovated and made more energy efficient than before, it is expected that CO2 emissions will be reduced. Therefore, the amount of reduction in the carbon tax costs corresponding to the reduction in CO2 emissions will be evaluated.

[0028] The "Environmental Certification and Rating" category is an evaluation item related to the acquisition of environmental certification and the rating of buildings based on evaluations by public institutions. For example, it is possible to estimate in advance whether a building can obtain environmental certification based on the results of improvements in its so-called "energy efficiency" through renovation and renewal, and how the building's rating will be evaluated by public institutions, and to evaluate the results after the fact.

[0029] "Business continuity planning and risk management" is an item that evaluates whether or not business operations can be continued while avoiding risks in the event of a disaster or the expected tightening of legal regulations in the future. For example, by installing solar power generation equipment, storage batteries, etc., which are related to so-called "energy creation" when a building is renovated or remodeled, it is expected that minimum functionality will be maintained and functionality recovery will be improved in the event of a disaster, power outage, etc. Therefore, the length of time that will enable at least minimum functionality to be maintained and functionality to be restored in the event of a power outage will be evaluated.

[0030] "Decrease in employee turnover rate" is an item that evaluates the tendency of building users to leave their jobs or the results of such leave. For example, it is expected that building renovations will improve the comfort of using the building and improve the evaluation of companies that use the building. In relation to this, it is expected that there will be a decrease in employees who leave the building due to not being able to work in a comfortable environment. Therefore, we will evaluate changes in the employee turnover rate.

[0031] "Internal awareness" is an item that evaluates the degree of awareness effect based on the expected effect of educating employees and users about the environment in the building. For example, if training to raise environmental awareness among employees and users is omitted, the costs required for that training can be reduced. Therefore, the costs saved by omitting the training to raise environmental awareness are evaluated. However, there are cases where the costs are small or the training cannot be omitted. If the degree of effect is relatively small, the evaluation of this item may be omitted.

[0032] "Funding" is an item that evaluates whether it is possible to raise funds at a preferential interest rate (low interest rate). For example, when raising funds for the renewal and renovation of a building, using sustainability-related financial products can sometimes make it possible to raise funds at preferential (low) interest rates. Therefore, we evaluate whether the conditions for using such financial products are met.

[0033] "Advertising" is an item that evaluates whether building renovations and upgrades can produce advertising effects that can replace advertising. For example, if the number of floors and scale of advertising can be reduced due to the advertising effects of the building, advertising costs can be reduced.

[0034] "Improvement of real estate value" is an item that evaluates the value of a building as real estate. For example, if part of the building becomes available for rent to tenants, revenue from rental fees can be expected.

[0035] Some of the evaluation processes for the above items may be omitted to the extent that they do not affect the analysis results. For example, in the category of "improving the aesthetics of interior and exterior," it is difficult to evaluate the designs of various buildings using uniform evaluation criteria, and it is also difficult to quantify the evaluation results. Therefore, in this analysis, this category was excluded from the evaluation process.

[0036] Additionally, the "environmental certification / rating" item includes compliance with environmental standards and building evaluations by third-party organizations. The former item is something that a building should, and must, meet the environmental standards of the land. The latter item is something that is based on building evaluations by third-party organizations, and the results of the evaluation cannot be determined at the planning stage of building renewal / renovation. Therefore, in this analysis, this item will be excluded from the evaluation process.

[0037] From the above perspective, in the following embodiment, examples of evaluation methods relating to items such as "health promotion," "improvement of intellectual productivity," "improvement of interior and exterior aesthetics," "reduction of carbon tax, etc.", "acquisition of environmental certifications and ratings," "business continuity planning and risk management," and "reduction of employee turnover rate" will be described.

[0038] (Information processing procedures) The information processing of the embodiment will be described with reference to FIG. FIG. 2 is a flowchart of information processing according to the embodiment. For example, the information acquisition unit 10 acquires initial data (S10). The calculation processing unit 30 selects the mode and the type of digestion process (S15). The processing unit 30 acquires the individual information (S20). The calculation processing unit 30 performs calculation processing (S25). The calculation processing unit 30 displays the calculation results on the display unit 40 (S30), and then the series of processes is completed. The above process is merely an example, and may be modified as appropriate without being limited to this. For example, some of the above processes may be repeated with different conditions, or some may be omitted.

[0039] The selection of the mode and the type of evaluation process according to the embodiment will be described with reference to FIG. FIG. 3 is a diagram for explaining the selection of a mode and a type of evaluation process according to the embodiment. This mode and evaluation process type selection screen is an example of a screen that accepts user operations to select a mode and an evaluation process type. For example, this selection screen is an example of a screen that allows selection of an evaluation "before updating and repairing," an evaluation "after updating and repairing," and "initial data registration."

[0040] For example, in step S10 above, initial data specifying the "initial data registration mode" is set. The initial data may include the following information: Basic information for the functioning of information processing system 1 - User, building, and project identification information (project name, identification number, etc. can be used) Information showing the characteristics of the building or project (For example, address, (latitude and longitude), site area, land use classification, surrounding information, building size (height, floor area, etc.), building use, client, main users, total number of employees, number of users of the building, past performance (operating profit, etc.), etc.) For example, the above information is stored in the storage unit 70 and used as information for each evaluation process.

[0041] The user selects the check box displayed on the selection screen that corresponds to the desired process and operates the "Next" button. The information acquisition unit 10 of the processing device 100 accepts the setting of this check box and the operation of the "Next" button, adds the setting information to the storage unit 70, and switches to the desired process.

[0042] Selection of evaluation items according to the embodiment will be described with reference to FIGS. FIG. 4 is a diagram for explaining a selection screen for evaluation items according to the embodiment. On this evaluation item selection screen, various selectable evaluation items are displayed with check boxes. Note that evaluation items that cannot be selected do not have check boxes displayed, and explanations are displayed as necessary. In this example, the following items are set as targets for processing: "health promotion," "improvement of intellectual productivity," "reduced maintenance costs," "reduction of carbon taxes, etc.", "business continuity planning and risk management," "reduced turnover," "advertising and promotion," and "improvement of real estate value." The user selects the selection area (each checkbox) displayed on the selection screen that corresponds to the desired process, checks the checkbox for the desired item, and operates the "Next" button or the "Back" button. The information acquisition unit 10 of the processing device 100 accepts the setting of this checkbox and the operation of the "Next" button, adds the setting information to the storage unit 70, and switches to the desired mode.

[0043] FIG. 5 is a diagram illustrating the NEB aggregation DB according to the embodiment. The NEB summary database includes each evaluation item, an evaluation implementation flag corresponding to each evaluation item, and a subtotal column for effects. The evaluation implementation flag corresponding to each evaluation item stores information indicating whether the item is enabled or disabled. Items for which the evaluation implementation flag is set to enabled are the evaluation items to be implemented. The results of each evaluation item treatment are written in the effect subtotal column. For example, the calculation processing unit 30 of the processing device 100 refers to the evaluation execution flag of this NEB totalization DB, performs the calculation processing required for the evaluation, and writes it in the effect subtotal column.

[0044] When the above initial data is set by the process of the "initial data registration mode" in step S15, the calculation processing unit 30 executes the following process.

[0045] For example, in step S10 above, when initial data specifying the "first evaluation processing mode" is set, the calculation processing unit 30 identifies the processing of the "first evaluation processing mode" (e.g., the evaluation processing before the update and modification) in step S15 and executes the following processing. In step S10 above, when initial data specifying the "second evaluation processing mode" is set, the calculation processing unit 30 identifies the processing of the "second evaluation processing mode" (e.g., evaluation processing after update and modification) in step S15 and executes the following processing.

[0046] In the case of "First evaluation processing mode" applied to evaluation before update / renovation: The evaluation processes applicable to the "first evaluation processing mode" are prepared so as to be identifiable at the initial registration stage. When the user specifies the "first evaluation processing mode," the calculation processing unit 30 identifies and executes the evaluation process before the update or modification. For example, evaluation processes that cannot be applied to the "first evaluation process mode" include evaluation processes for which data is not available before the building is updated or renovated.

[0047] Based on the above, an evaluation calculation is carried out for each evaluation item. For example, the processing unit 30 displays a display screen for acquiring individual information, and acquires the individual information for each evaluation item based on the answers to the items displayed on the display screen (adding checks to the checkboxes of the requested items) and the entries in the answer fields for acquiring the individual information (S20). Examples of the above display screen will be described later.

[0048] The calculation processing unit 30 performs predetermined calculation processing for the evaluation items designated as requiring evaluation using the individual information acquired in step S20 (S25). For example, the calculation processing unit 30 writes the acquired individual information for each of the evaluation items into the storage unit 70 as effect data and stores it therein.

[0049] The calculation processing unit 30 refers to the effect data in the storage unit 70 and displays the result of the calculation processing in step S25 (calculation result) (S30).

[0050] The above is an example of the "first evaluation processing mode," but the same applies to the "second evaluation processing mode." In this case, some of the evaluation items may be different, but the calculation processing unit 30 identifies and executes the evaluation processing after the update and modification.

[0051] (Evaluation item details) Next, the evaluation items will be described in detail.

[0052] "Health Promotion" section: With reference to FIG. 6, an evaluation method for "health promotion" according to the embodiment will be described. Fig. 6 is a diagram for explaining a selection screen for an evaluation method related to "health improvement" in the embodiment. Fig. 7 is a diagram for explaining an example of a storage area used for evaluation related to "health improvement" in the embodiment.

[0053] For example, FIG. 7 shows the "health promotion evaluation related data DB." The "health promotion evaluation related data DB" stores the values ​​of the numerical data set in the items associated with the input fields on the selection screen for the "health promotion" evaluation method described above.

[0054] The selection screen for the evaluation method for "health promotion" shown in Figure 6 displays a selection area (an area including check boxes surrounded by dashed lines) for accepting the selection of the "health promotion" evaluation method, as well as input fields for accepting setting data. In this example display, it is possible to accept the selection result of one of three evaluation methods and various data. The user selects the selection area (each checkbox) displayed on the selection screen for the "health promotion" evaluation method that corresponds to the desired processing, enters the desired data in the input field, and operates the "Next" button or the "Back" button. The information acquisition unit 10 of the processing device 100 accepts the setting of this checkbox and the operation of the "Next" button, adds the setting information to the storage unit 70, and switches to the desired mode.

[0055] As evaluation methods for the "health promotion" item, we propose two evaluation methods that focus on presenteeism and absenteeism, and an evaluation method that uses the amount of self-paid medical expenses.

[0056] Presenteeism is the act of working while sick. It can lead to reduced productivity, poor health, and the spread of infectious diseases in the workplace. Absenteeism is what we call absence from work. Presenteeism and absenteeism can be associated with reduced organizational efficiency. Building renovations and upgrades can be expected to reduce presenteeism and absenteeism by improving the work environment.

[0057] The following information is used in the evaluation process for the "health promotion" item. This information is set in a predetermined storage area of ​​the storage unit 70 based on the result of a registration operation performed by the user while an operation screen (display screen) is displayed on the display unit of the processing device 100.

[0058] Each variable is defined as follows: Number of employees: The total number of employees of the company using the building. Number of regular employees: The number of regular employees among all employees of the company that uses the building. Number of people affected: The number of employees using the building. Occupancy rate: The probability that employees using the building are present. Operating profit: The operating profit of the company that uses the building. Absenteeism rate before renovation: The absenteeism rate of employees using the building before renovation. Absenteeism rate after renovation: The absenteeism rate of employees using the building after renovation. Stress check result improvement rate: Based on a stress check survey of employees using the building, this result was obtained by comparing the change in the percentage of people who answered that their stress results were good before and after the renovation and update. Average health insurance payment difference: The average amount paid (out-of-pocket) when medical treatment is received using health insurance for all employees of the company using the building.

[0059] The processing device 100 uses the above information to perform the following processing.

[0060] First evaluation method: The first evaluation method utilizes the effect of absenteeism. For example, the following formula is used for quantitative evaluation: (Health Promotion Evaluation) = (Absentee rate before renovation - Absentee rate after renovation) x Number of regular employees x Value added

[0061] In the above formula, the "absentee rate before renovation" and "absentee rate after renovation" are calculated by applying the absenteeism rate of employees in the organization that uses the building being evaluated. The number of regular employees is the number of employees (regular employees) belonging to the organization that uses the building.

[0062] If it is not possible to identify the absenteeism rate before the renovation as described above, a simple method may be to apply a figure based on general trends. For example, it is known that high-stress individuals, who are classified as having higher stress levels than normal individuals, make up approximately 10% of the people being assessed. The loss caused by absenteeism by these high-stress individuals can be calculated by using the average loss amount per person.

[0063] Second evaluation method: The second evaluation method utilizes presenteeism. The processing unit may perform the following processing for the evaluation of the health promotion after the update and modification. For example, the health promotion effect may be derived based on the stress sensitivity response results of the subject group using the building, the time spent in the building (referred to as the impact ratio), and the value (added value) obtained from the work of the subject group, and included in the secondary effect. More specifically, the health promotion effect may be derived based on the improvement rate based on a representative value (e.g., average) of the stress sensitivity response results of the subject group using the building, the number of subjects in the subject group (referred to as the impact ratio) and the ratio of time spent in the building (referred to as the impact ratio), and the value (added value) obtained from the work of the subject group, and included in the secondary effect.

[0064] For example, the following formula is used for this quantitative evaluation:

[0065] (Health Promotion Evaluation) = (Stress check result improvement rate) x (number of people affected) x (impact rate) x (value added)

[0066] In the above formula, "number of affected people" refers primarily to the number of employees working at the facility. "Impact rate" refers to the percentage of time that employees working at the facility are present at the facility (presence rate). "Value added" refers to the operating profit per employee of the company that uses the building.

[0067] Third evaluation method: The third evaluation method uses out-of-pocket medical expenses. The processing unit may perform the following processing for the evaluation of the health promotion after the update and modification. For example, the health promotion effect may be derived using the amount of health insurance payments made by the group of subjects who use the building and the time spent in the building, and the result may be included in the secondary effect. More specifically, the health promotion effect may be derived using a representative value (for example, average) of the amount of health insurance payments made by the group of subjects who use the building, the number of people in the group (the number of people affected), and the time spent in the building, and the result may be included in the secondary effect.

[0068] For example, the following formula is used for this quantitative evaluation:

[0069] (Health Promotion Evaluation) = (average health insurance payment difference) x (number of people affected) x (impact rate)

[0070] In the above formula, the "average health insurance payment difference" refers to the amount of medical expenses (self-pay amount) paid individually by employees of the company that uses the building when receiving insured medical treatment, averaged across all employees of the company. With this third evaluation method, it takes time to obtain the aggregate results of out-of-pocket medical expenses, but it is possible to use information based on the results of employees' actual medical treatment. Although an example of a formula using an average amount has been given, as mentioned above, the total amount of the company may also be used.

[0071] "Improvement of intellectual productivity" section: An evaluation of the "improvement of intellectual productivity" of the embodiment will be described.

[0072] For example, as an evaluation method for the item "improvement of intellectual productivity," an evaluation method relating to business efficiency and an evaluation method relating to increased added value are proposed.

[0073] Evaluation method for business efficiency: This is an evaluation method that uses the amount of reduction in overtime pay as an indicator based on the total annual working hours, productivity improvement rate, number of affected people, and overtime pay unit price.

[0074] (Amount of reduction in overtime pay) = Total annual working hours x (1-1 / productivity improvement rate) x number of people affected x unit price of overtime pay

[0075] In the above formula, for example, the "number of affected employees" refers to the number of employees primarily engaged in office work. The unit price of overtime pay is the basis for the hourly wage (unit price) specified as overtime pay.

[0076] Evaluation method for added value increase: This is an evaluation method based on the number of employees, operating profit per employee, and productivity improvement rate. The increase in added value is calculated using the following formula:

[0077] Increase in added value = Number of employees x (operating profit per employee) x (productivity improvement rate - 1)

[0078] Here, an example of deriving the above-mentioned "productivity improvement rate" will be described with reference to FIGS.

[0079] FIG. 8 is a diagram illustrating a selection screen for selecting an evaluation method for "improvement of intellectual productivity" according to the embodiment. The calculation processing unit 30 selects a coefficient from the "coefficient data DB for intellectual productivity evaluation" based on the registered data.

[0080] 9 to 12 are diagrams for explaining configuration examples of storage areas used for various processes relating to "improvement of intellectual productivity" in the embodiment. First, configuration examples of storage areas used for various processes will be explained.

[0081] FIG. 9 shows the "Intellectual Productivity Evaluation Coefficient Data DB." The "Intellectual Productivity Evaluation Coefficient Data DB" stores data on coefficients used to evaluate "improvement of intellectual productivity." For example, each item is divided into three ranks: "pine," "bamboo," and "plum." A coefficient is set for each rank of each item. The value of this coefficient may be set in advance to a fixed value as an initial value. The coefficient value for each rank of each item may be set to have a monotonically increasing or decreasing tendency.

[0082] FIG. 10 shows the "effect data DB." The "Effect Data DB" stores intermediate evaluation data and evaluation results. For example, each item includes items such as the usage pattern of the "Buildings and Facilities," the "Rank," and the "Effect" of usage. The usage pattern of the "Buildings and Facilities" is associated with each piece of equipment and its characteristics. The "Rank" is associated with the results of ranking the degree of usage pattern of the "Buildings and Facilities." The "Effect" of usage is associated with the effect when the "Buildings and Facilities" is used at the above rank.

[0083] Figure 11 shows the "condition setting TBL" used to evaluate the effect of task and ambient lighting on intellectual productivity. The rank of task and ambient lighting usage patterns is determined using this "Condition Setting TBL." For example, as shown in this "Condition Setting TBL," a rank ("pine," "bamboo," or "plum") is determined by combining the results of the user's responses to items such as "task lighting function available," "individual adjustment possible," and "the type of work is calculation work." If you answer all three of the above requirements affirmatively (marked with a circle), you will be judged to be in the "Matsu" rank. For the three requirements above, if the user answers affirmatively (marked with a circle) to two of the questions "has the function to use task lighting" and "can be adjusted by the individual," and if the user answers negatively (left blank) to the question "the work involves calculation work," the system is judged to be in the "Bamboo" rank. For the three requirements above, if one of the questions "has a function for using task lighting" is answered affirmatively (marked with a circle), and two questions "can be adjusted by the individual" and "the user's work involves calculations" are answered negatively (marked with a blank), the device is judged to be in the "Plum" rank. For example, the processing unit 30 can determine the effect of task / ambient lighting based on the user's response by referring to the "condition setting table" as described above. The processing unit 30 adds the effect result obtained by this process to a predetermined effect column in the "effect data database."

[0084] Figure 12 shows the "condition setting TBL" used to evaluate the effect of circadian lighting on intellectual productivity. For example, assume that circadian lighting is used in one of three ways shown in the condition setting TBL. The rank of the circadian lighting usage pattern is determined using this "condition setting TBL." For example, as shown in this "condition setting TBL," there are three options: "circadian lighting use," "high degree of illuminance increase," and "low degree of illuminance increase," and a rank is set according to each option. The calculation processing unit 30 determines the rank ("pine," "bamboo," or "plum") based on the user's response by referring to this "condition setting TBL" as described above. The calculation processing unit 30 adds the results of the effects obtained by this process to the predetermined effect column of the "effect data DB."

[0085] For example, the calculation processing unit 30 may perform an evaluation regarding "improvement of intellectual productivity" and derive the effect of the evaluation item regarding "improvement of intellectual productivity."

[0086] First, we will organize the evaluation items related to buildings and building facilities regarding "improving intellectual productivity."

[0087] <Light environment> Regarding the lighting environment, it is a good idea to evaluate items such as "use of task / ambient lighting," "use of circadian lighting," "function to adjust illuminance," and "function to adjust lighting color."

[0088] The evaluation of "Use of Task and Ambient Lighting" will be based on the answers to the following three confirmation items. These three items are independent, and multiple significant answers can be selected. Task lighting available Individually adjustable The work involves calculations The evaluation of "Use of circadian lighting" and "Adjustable illumination function" will be based on the answers to the following three confirmation items. These three items are interrelated, and significant answers will be multiple choice. Circadian lighting use Increase in illuminance: High Increase in illuminance: Large Increase in illuminance: High Increase in illuminance: Small Regarding the "lighting color adjustment function," evaluation will be based on the answers to the following questions: Lighting color adjustment function: Yes

[0089] <Thermal environment / air environment> The thermal environment / air environment is generally controlled using air conditioning equipment to keep the temperature and humidity within a desired range. In such cases, the set temperature affects the operation of the air conditioning equipment. For example, it is preferable to be able to set room temperatures separately for winter and summer (winter set temperature, summer set temperature). More specifically, the evaluation value of the set temperature may be obtained using a linear function that calculates the evaluation value (value of "effectiveness") using the winter set temperature or summer set temperature as a variable, or the evaluation value may be determined by referring to a predetermined conversion table. In addition, the thermal environment / air environment can be evaluated in terms of "use of thermal systems such as insulation materials and heat exchange," "use of efficient air conditioning systems," "use of heat pump systems (task air conditioning)," "zoning with separate temperature zones," etc., and the evaluation values ​​obtained from these can be added to the evaluation value based on the above set temperature.

[0090] As mentioned above, there are a wide variety of evaluation items related to productivity improvement rates, which are related to intellectual productivity. Therefore, when compiling the evaluation results by simple addition, the value of the evaluation result tends to increase according to the number of evaluation items. Therefore, in this embodiment, it is proposed to derive the productivity improvement rate using the following formula.

[0091] (Productivity improvement rate) = (Effect of Measure A x Effect of Measure B x... x Effect of Measure N) R x (influence artificial ratio)

[0092] The "affected population ratio" in this formula is derived from the product of the number of people using the building where each of the measures from Measure A to Prototype N has been implemented and the proportion of time spent sitting in a designated seat in the building. The "R" in this equation defines the elasticity of production with respect to the type of labor. It is known that it is best to set different values ​​for each industry.

[0093] By using the above formula, it is possible to easily derive the productivity improvement rate even when the number of types of measures varies.

[0094] Next, a method for evaluating the effect of reducing maintenance costs will be described with reference to FIGS. FIG. 13 is a diagram for explaining a selection screen for the evaluation method of "maintenance cost reduction" in the embodiment. FIG. 13 shows an example of a selection screen for evaluating the amount of reduction in maintenance costs for air conditioning equipment, lighting equipment, solar power generation equipment, etc. This selection screen includes columns for accepting information regarding the air conditioning equipment, such as the annual operating hours before and after the renewal and renovation, the compressor lifespan, and the maintenance costs associated with replacing the compressor. Regarding lighting equipment, there are columns for accepting information such as the annual lighting hours before and after the renewal and renovation, the lifespan of the lighting fixtures, and maintenance costs associated with replacing compressors. Regarding solar power generation facilities, columns are provided for accepting solar power generation facility capacity, maintenance costs per unit capacity, etc.

[0095] FIG. 14 is a diagram for explaining the "maintenance cost reduction evaluation related data DB" used to evaluate the effect of maintenance cost reduction in the embodiment.

[0096] For example, the maintenance cost reduction evaluation related data DB stores information on coefficients used in the "maintenance cost reduction" evaluation process and individual setting values.

[0097] The calculation processing unit 30 adds various data received using the operation screen to the "maintenance cost reduction evaluation related data DB."

[0098] HVAC maintenance cost savings: The calculation processing unit 30 may derive the amount of reduction in maintenance costs for the air conditioning equipment using data on the air conditioning equipment in the "Maintenance Cost Reduction Evaluation Related Data DB" and the following formula.

[0099] (Amount of reduction in maintenance costs for air conditioning equipment) = (annual operating hours before renovation - annual operating hours after renovation) ÷ (compressor lifespan) x (maintenance costs associated with compressor replacement)

[0100] Lighting maintenance cost savings: The calculation processing unit 30 may derive the amount of reduction in maintenance costs for the lighting equipment using data on the lighting equipment in the "maintenance cost reduction evaluation related data DB" and the following formula.

[0101] (Reduction in maintenance costs for lighting equipment) = (Annual lighting hours before renovation - Annual lighting hours after renovation) ÷ (Lifespan of lighting fixture) x (Maintenance costs associated with replacing lighting fixture)

[0102] In addition, when changing fluorescent lamps to LED fixtures as part of renovations and upgrades, it is a good idea to change the fixtures' lifespan and maintenance costs before and after the upgrades and upgrades.

[0103] Solar power plant maintenance cost savings: The calculation processing unit 30 may derive the amount of reduction in maintenance costs related to the photovoltaic power generation facility using data related to the photovoltaic power generation facility in the "maintenance cost reduction evaluation related data DB" and the following formula.

[0104] (Savings on maintenance costs for solar power generation equipment) = (PV power generation capacity before renovation - PV power generation capacity after renovation) x (maintenance costs)

[0105] If solar power generation equipment has not been used up until now, or if its capacity is to be increased, the derived reduction amount will be a negative value, resulting in an increase.

[0106] The effect of the above "maintenance cost reduction" may be calculated by adding up the above calculated "maintenance cost reduction amounts."

[0107] Next, the effects of reducing carbon taxes and the like will be described with reference to FIGS. 15 and 16. Fig. 15 is a diagram for explaining a selection screen for an evaluation method of "reduction of carbon tax, etc." Fig. 16 is a diagram for explaining a "carbon tax reduction evaluation related data DB" used for evaluating the effect of carbon tax reduction in the embodiment.

[0108] The following items regarding carbon tax reductions will be evaluated. As mentioned above, the items for evaluation regarding the reduction of carbon taxes, etc. include the amount of energy use reduction and CO2 emissions. It is recommended to select either the amount of energy use reduction or the amount of reduced CO2 emissions as the item regarding the reduction of carbon taxes, etc. For example, the carbon tax reduction amount can be calculated using the following formula, which includes the amount of energy use reduction as a variable:

[0109] (Carbon tax reduction amount) = (reduced energy use) x (CO2 emissions intensity) x (carbon price)

[0110] In the above formula, the amount of energy usage reduction is the amount of energy usage that has been reduced or is expected to be reduced by the renewal and renovation, compared to the current amount of energy usage (before the renewal and renovation). CO2 emissions per unit of production refers to the amount of CO2 emitted per unit of economic activity. Carbon pricing is a conversion rate for converting CO2 emissions into monetary value, for example, the amount per ton of CO2 emissions. It is set so that companies are required to pay an economic burden (tax amount) according to the amount of CO2 they emit, which leads to a reduction in CO2 emissions.

[0111] For example, the carbon tax reduction amount can be calculated using the following formula, which includes CO2 emissions as a variable:

[0112] (Carbon tax reduction amount) = (CO2 emissions before renovation) x (CO2 emission reduction rate due to renovation) x (carbon price)

[0113] In the above formula, CO2 emissions before renovation refers to the CO2 emissions when using the building and various facilities before renovation. The O2 emission reduction rate associated with renovation and refurbishment is the reduction rate (rate of change) of CO2 emissions that changes as a result of renovation and refurbishment.

[0114] The calculation processing unit 30 may derive the effect of reducing the carbon tax based on the amount of carbon dioxide emissions resulting from the implementation of measures to reduce carbon dioxide emissions or energy usage, and include this effect in the secondary effects. More specifically, the calculation processing unit 30 may derive the effect of reducing the carbon tax based on the carbon price and the reduction rate of carbon dioxide emissions resulting from the implementation of measures to reduce carbon dioxide emissions or energy usage.

[0115] Next, we will explain the effects of obtaining environmental certification and ratings. The items related to obtaining environmental certification and ratings include obtaining environmental certification and building ratings. For example, obtaining environmental certification and ratings can increase the asset value of real estate by implementing ZEB measures (renovations and renovations).

[0116] For example, well-known environmental certifications include BELS (registered trademark, Building-Housing Energy-efficiency Labeling System), LEED (registered trademark, Leadership in Energy & Environmental Design), and CASBEE (registered trademark, Comprehensive Assessment System for Built Environment Efficiency) real estate assessment certification.

[0117] In addition, WELL and CASBEE Wellness Office are well-known building ratings. The former is a building evaluation system developed and operated by the International WELL Building Institute (IWBI) in the U.S. that focuses on the physical and mental health of building occupants, while the latter is an example of a tool provided by CASBEE to evaluate building specifications, performance, and initiatives.

[0118] Obtaining such environmental certifications and ratings is expected to increase the assessed value of the property (increase in asset value) and contribute to branding effects. In this embodiment, an example is shown in which the analysis of these evaluation items is carried out by grouping them into the "real estate value" item, which will be described later.

[0119] Next, the effects of "business continuity planning and risk management" will be described with reference to FIGS. 17 and 18. Fig. 17 is a diagram for explaining an example of an operation screen for selecting an evaluation method for the processing of "business continuity planning and risk management" according to the embodiment. Fig. 18 is a diagram for explaining an example of a BCP / risk avoidance evaluation related data DB used for the processing of "business continuity planning and risk management" according to the embodiment.

[0120] We provide three methods for evaluating "Business Continuity Planning and Risk Management."

[0121] For example, the following items related to "Business Continuity Planning and Risk Management" are evaluated. As mentioned above, the effect of the items related to "business continuity planning and risk management" is calculated by adding its basic effect and the labor costs required for recovery. The basic effect can be calculated in two ways.

[0122] More specifically, the first basic effect of "Business Continuity Planning and Risk Management" can be calculated using the following formula:

[0123] (First basic effect of "Business Continuity Planning and Risk Management") = (annual electricity consumption) x (unit cost of damage caused by power outage) x (percentage of time that power supply is outage per year)

[0124] The annual electricity consumption is the annual electricity consumption of the building. The supply interruption damage cost unit is a conversion rate used to calculate the amount of damage when an electricity supply interruption (such as a power outage) occurs. The annual percentage of power outage time is the percentage of time that power supply is outage during a year.

[0125] In addition, the second basic effect of "Business Continuity Planning and Risk Management" can be calculated using the following formula:

[0126] (Second basic effect of "Business Continuity Planning and Risk Management") = (time to avoid business interruption) x (amount of loss due to power outage)

[0127] The time during which business interruption was avoided is the total time during which business was not interrupted and the effects of a power outage were avoided due to the implementation of power outage countermeasures. The loss amount due to a power outage is the loss incurred due to the occurrence of a power outage.

[0128] For example, in evaluating the business continuity plan and risk management, the calculation processing unit 30 may derive the effect of the evaluation of the business continuity plan and the risk management from the number of hours that business suspension (or suspension of operations) was avoided by power supply from the emergency power supply equipment during a power outage and an amount based on the profit amount per unit time, and include the effect in the secondary effect.

[0129] For example, to calculate the labor costs required for recovery when a failure occurs, the following formula can be used.

[0130] (Labor costs required for recovery) = (man-hours required for recovery) x (labor cost)

[0131] The sum of either the first or second basic effect above and the labor costs required for recovery should be used as the evaluation of "business continuity planning and risk management."

[0132] Next, the effect of reducing the turnover rate will be described with reference to FIGS. Fig. 19 is a diagram for explaining a selection screen for an evaluation method of "decrease in turnover rate" according to an embodiment. Fig. 20 is a diagram for explaining an example of a turnover rate decrease evaluation related data DB used for evaluating "decrease in turnover rate" according to an embodiment.

[0133] The following items related to reducing employee turnover will be evaluated. As mentioned above, the effect of items related to reduced turnover rates is calculated using three methods and then added together to derive the effect. The first method for deriving the effect of reduced turnover rates is the amount of reduction in mid-career recruitment costs, the second method is the amount of reduction in training costs, and the third method is the cost required for employment promotion.

[0134] For example, in the first calculation method, the following formula is used to calculate the partial effect of the reduction in turnover rate as the amount of reduction in mid-career recruitment costs.

[0135] (Mid-career recruitment cost reduction amount) = (recruitment cost per person) x (required number of mid-career hires) = (per person mid-career recruitment cost) x ((number of employees) x (percentage of employees leaving for personal reasons) x (percentage of employees leaving due to office environment issues) x (decrease in turnover rate due to renovations))

[0136] The cost of mid-career recruitment per person is the cost required to hire one mid-career employee. The number of employees is the number of employees belonging to the company that uses the building. The percentage of people who left their jobs for personal reasons is the ratio of people who chose to leave their jobs for personal reasons to the total number of people who left their jobs. The percentage of employees who left their jobs due to the office environment is the ratio of the number of people who chose to leave their jobs because they could not adapt to the office environment to the total number of people who left their jobs. A decrease in turnover rate following renovations and updates refers to a decrease in the number of people who are thought to have postponed leaving their jobs due to an improvement in the office environment as a result of renovations and updates.

[0137] For example, in the second calculation method, the following formula is used to calculate the partial effect of reduced turnover rate as the amount of training cost reduction.

[0138] (Training cost reduction) = (Labor costs) x (Training period) x (Number of employees reduced)

[0139] Labor costs are the fixed costs per training participant. The training period includes the training implementation date and the days before and after the scheduled training implementation date. The number of employees reduced is the number of mid-career employees that could be reduced as a result of the renovations and updates.

[0140] For example, in the third calculation method, the following formula is used to calculate the partial effect of a reduction in the turnover rate as the amount of reduction in employment promotion costs.

[0141] (Amount of employment promotion cost reduction) = (Mid-career recruitment cost per person) x (Number of people hired) x (Contribution rate of renovations and updates as reasons for choosing the company)

[0142] The cost per person for mid-career recruitment is the cost incurred per person when hiring a mid-career employee. The number of hires is the number of mid-career hires. The contribution rate of renewal and renovation as a reason for choosing a company is the ratio of the number of mid-career recruits who apply for a job because renewal and renovation were carried out and who cited this as a reason for choosing a company to the number of mid-career recruits who were hired after the renewal and renovation.

[0143] As a result of the renovation and renewal work, there will be fewer employees leaving the company compared to past trends, which will eliminate the need to hire additional mid-career employees. As a result, the costs of recruiting mid-career employees will be reduced compared to past trends.

[0144] For example, the calculation processing unit 30 may derive the effect of evaluating the reduction in turnover rate from an amount based on the amount of reduction in training costs for mid-career employees and the amount of reduction in costs required to promote the employment of the mid-career employees by increasing awareness of the implementation of updates and renovations, and include this in the secondary effects related to NEBs.

[0145] Next, the evaluation of the effect of reducing advertising expenses will be described with reference to FIGS. 21 and 22. FIG. Fig. 21 is a diagram for explaining a selection screen for an evaluation method of the "effectiveness of reducing advertising expenses" in the embodiment. Fig. 22 is a diagram for explaining an example of an advertising evaluation related data DB used for evaluating the "effectiveness of reducing advertising expenses" in the embodiment. The following items regarding the amount of advertising and promotional cost reduction will be evaluated. As mentioned above, the effect of the items related to the amount of reduction in advertising expenses is calculated using the following formula.

[0146] (Advertising cost reduction) = (number of broadcast articles) x (posting price per article)

[0147] The number of broadcast articles refers to the number of cases in which advertisements were not broadcast or published. To simplify the explanation, we will ignore price differences due to differences in media and advertising volume and use a common unit price per article (posting price per article).

[0148] Next, the effect of improving real estate value will be described with reference to FIGS. Fig. 23 is a diagram for explaining a selection screen for an evaluation method of "effects related to improvement of real estate value" in the embodiment. Fig. 24 is a diagram for explaining an example of a real estate value evaluation related data DB used for evaluation of "effects related to improvement of real estate value" in the embodiment. As mentioned above, the effect of items related to improving real estate value is calculated using the following formula.

[0149] (Changes in real estate values) = (difference in assessed value using cost method) + increase in rent = (Procurement cost difference) x (Total floor area) x (Cost rate) + Rent increase

[0150] <"Improvement in real estate value" evaluation method> The procurement cost difference is the price (cost) required to re-purchase the real estate (building) being evaluated. The total floor area above is the total floor area of ​​the real estate being assessed. The cost ratio indicates the degree of decline in the value of the real estate being evaluated over time. The rent increase amount is the amount by which the rent is increased when part or all of the building is rented.

[0151] After deriving the productivity improvement rate, the calculation processing unit 30 writes and stores the result in the NEB aggregation DB in the storage unit 70. This concludes the explanation of the NEB evaluation process.

[0152] According to this embodiment, the information processing system 1 can more accurately evaluate the effects (NEBs) of building renovations and refurbishments by deriving the degree of secondary effects obtained from the renovations and refurbishments based on the evaluation results of a group of evaluation items other than reductions in energy and utility costs, among the effects expected from the renovations and refurbishments of buildings or building equipment.

[0153] According to the above embodiment, the information processing system is equipped with a processing unit that derives the degree of secondary effects obtained from the renewal and renovation of a building or building equipment based on the evaluation results of a group of evaluation items other than reduction in energy usage and reduction in utility costs, among the effects expected from the renewal and renovation of the building, thereby enabling a more accurate evaluation of the effects (NEBs) of the renewal and renovation of the building.

[0154] Although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included within the scope and spirit of the invention, as well as within the scope of the invention described in the claims and their equivalents.

[0155] (Variation) The process of the modified embodiment will be described with reference to FIG. In the above embodiment, the quantification of effects related to evaluation items other than the ZEB-related item group has been described. In this modified example, a method for evaluation including the effects of ZEB-related items will be described.

[0156] FIG. 25 is a flowchart of information processing according to a modified example of the embodiment. The process up to step S30 is the same as that in FIG. The processing up to step S30 quantifies the effects related to evaluation items other than the ZEB-related items.

[0157] The calculation processing unit 30 obtains the evaluation results of the ZEB-related item group from, for example, an external device, or performs the evaluation process of the ZEB-related item group itself, and quantifies the effects related to the evaluation items of the ZEB-related item group (S40).

[0158] The calculation processing unit 30 derives an evaluation result that combines the evaluation results of the ZEB-related item group and the evaluation results of evaluation items other than the ZEB-related item group (S50).

[0159] As mentioned above, the secondary effects include the first effect related to the evaluation item of "assessment of energy usage reduction (through energy conservation and energy creation evaluated by ZEB (Net Zero Energy Building))" expected from the renewal and renovation of the building or the equipment, and in addition to the first effect, the second effect related to other evaluation items in the evaluation item group (ZEB-related item group).

[0160] (Addendum) The information processing system of the embodiment may be configured as follows. (1) An information processing system according to an embodiment includes a processing unit that derives the degree of a secondary effect obtained from the renewal or renovation of a building or building equipment based on an evaluation result of a group of evaluation items other than reduction in energy usage and reduction in utility costs, among effects expected from the renewal or renovation of the building or building equipment.
