[0003] [Patent Document 1] Japanese Patent Application Publication No. 2019-196877 Summary of the Invention [Problem to be solved by the invention]

[0004] In recent years, the introduction of remote work has led to changes in employee work styles, and as work styles change, there is a growing trend to change the layout of seating and other aspects of target spaces such as offices. In such cases, the proposer of the layout change may need to evaluate whether the office or other space is being used in accordance with their wishes (e.g., a desire for more active interaction between employees) after the layout change and determine whether the layout should be further improved. However, even if the proposer uses the technology disclosed in Patent Document 1, it may be difficult to make a quantitative evaluation.

[0005] The present disclosure has been made in consideration of the above-mentioned reasons, and aims to provide an evaluation system, an evaluation method, and a program that can easily provide results based on more quantitative evaluation of layout changes. [Means for solving the problem]

The evaluation system includes an environment acquisition unit, a request acquisition unit, an evaluation processing unit, and an output unit. The environment acquisition unit acquires first environmental information including one or more environmental elements in the target space before the layout change and second environmental information including the one or more environmental elements after the layout change. The request acquisition unit acquires change request information including a request for a change to the layout. The evaluation processing unit derives an evaluation result for the layout after the change compared to the layout before the change. The output unit outputs the evaluation result. The evaluation processing unit calculates difference information of the second environmental information with respect to the first environmental information. The evaluation processing unit determines a threshold value according to the change request information. The evaluation processing unit derives the evaluation result based on a result of comparing the difference information with the threshold value.

[0007] An evaluation method according to one aspect of the present disclosure is applied to an evaluation system that evaluates layout changes for a target space of a facility. The evaluation method includes an environment acquisition process, a request acquisition process, an evaluation process, and an output process. The environment acquisition process acquires first environment information including one or more environmental elements in the target space before the layout change, and second environment information including the one or more environmental elements after the layout change. The request acquisition process acquires change request information including a request for a change to the layout. The evaluation process derives an evaluation result for the layout before the change and the layout after the change. The output process outputs the evaluation result. The evaluation process obtains difference information of the second environment information from the first environment information. The evaluation process determines a threshold value according to the change request information. The evaluation process derives the evaluation result based on a result of comparing the difference information with the threshold value.

DETAILED DESCRIPTION OF THE INVENTION

[0011] (overview) The following describes an evaluation system, an evaluation method, and a program according to embodiments and modifications, with reference to the accompanying drawings. Note that the following embodiments and modifications are merely examples of various embodiments of the present disclosure. Furthermore, the following embodiments and modifications can be modified in various ways depending on the design, etc., as long as the object of the present disclosure can be achieved. Furthermore, the configurations of the modifications can be combined as appropriate.

[0012] As shown in FIG. 1 , an evaluation system A1 according to one embodiment evaluates a layout change for a target space S1 in a facility 100. In the following description, as an example, the facility 100 is an office building, and the target space S1 is a single management space 2 (e.g., a work space or a room such as a conference room) in the office. The target of the layout change is assumed to include, for example, the seats of employees working in the office. The target of the layout change may include communication equipment such as copy machines, printers, servers, and routers, shelves, and ornamental plants, in addition to seats. The facility 100 is not limited to an office building, as long as it has one or more management spaces 2 whose layout may require a change. The facility 100 may be a non-residential facility such as a theater, movie theater, public hall, amusement park, complex, restaurant, department store, school, hotel, inn, hospital, nursing home, kindergarten, library, museum, art gallery, underground shopping mall, station, or airport. Alternatively, the facility 100 may be a residence or the like.

[0013] 1, the evaluation system A1 includes an environment acquisition unit 11, a request acquisition unit 12, an evaluation processing unit 13, and an output unit 14. The environment acquisition unit 11 acquires first environment information B1 including one or more environmental elements in the target space S1 before the layout is changed, and second environment information B2 including one or more environmental elements in the target space S1 after the layout is changed. Here, the one or more environmental elements include at least one of the temperature, humidity, noise, congestion level, and carbon dioxide concentration of the target space S1.

[0014] The request acquisition unit 12 acquires change request information C1 including requests for changes to the layout. The "change request" here refers to the request of a proposer (hereinafter sometimes simply referred to as a "user") who proposes a change to the layout. For example, the request acquisition unit 12 acquires the change request information C1 by a user's operation input to the terminal 4 (see FIG. 1). The user may be, for example, a member of the general affairs department of an office who manages the management space 2 and the employees who work in the management space 2. The user may determine their requests in advance by, for example, conducting a survey of employees.

[0015] The evaluation processing unit 13 derives an evaluation result for the layout before and after the layout change. The output unit 14 outputs the evaluation result. The evaluation processing unit 13 obtains difference information between the first environmental information B1 and the second environmental information B2. The evaluation processing unit 13 determines a threshold value according to the change request information C1. The evaluation processing unit 13 derives the evaluation result based on the result of comparing the difference information with the threshold value.

[0016] According to the configuration of this evaluation system A1, the evaluation of the layout change is automatically performed taking into consideration a threshold value according to the change request (from the user) and difference information between the actual layout before and after the change. Therefore, the evaluation system A1 has the advantage of being able to easily provide results based on a more quantitative evaluation of the layout change.

[0017] In the following, it is assumed that the above-described functions of the evaluation system A1 are implemented in a server that may be installed outside the facility 100 (or inside the facility 100). The server includes one or more server devices. When the server includes multiple server devices, a cloud (cloud computing) may be constructed by the multiple server devices.

[0018] The server communicates wirelessly with a gateway of the facility 100. The server communicates with a terminal 4 and various sensors 3 (for detecting environmental elements) via the gateway. However, it is not necessary that all of the above-described functions of the evaluation system A1 be implemented in the server, and at least some of the functions may be implemented in a device other than the server. For example, at least some (e.g., all) of the above-described functions of the evaluation system A1 may be implemented in a device on the facility 100 side, such as a gateway or a controller of a BEMS (Building Energy Management System). Furthermore, at least some (e.g., all) of the above-described functions of the evaluation system A1 may be implemented in a terminal 4 used by a user.

[0019] An evaluation method according to one embodiment is applied to an evaluation system A1 that evaluates a layout change for a target space S1 of a facility 100. The evaluation method includes an environment acquisition process, a request acquisition process, an evaluation process, and an output process. The environment acquisition process acquires first environment information B1 including one or more environmental elements in the target space S1 before the layout change, and second environment information B2 including one or more environmental elements after the layout change. The request acquisition process acquires change request information C1 including a request for a change to the layout. The evaluation process derives an evaluation result for the layout before the change and the layout after the change. The output process outputs the evaluation result. The evaluation process obtains difference information between the first environment information B1 and the second environment information B2. The evaluation process determines a threshold value according to the change request information C1. The evaluation process derives the evaluation result based on a result of comparing the difference information with the threshold value.

[0020] This evaluation method also has the advantage of making it easier to provide results based on more quantitative evaluations of layout changes.

[0021] This evaluation method is used on a computer system (evaluation system A1). In other words, this evaluation method can also be embodied as a computer program. A program according to one aspect is a program for causing one or more processors to execute the above evaluation method. The program may be recorded on a computer-readable non-transitory recording medium. Furthermore, a computer program product according to one aspect includes a computer program that, when executed by one or more processors, implements the processing (steps) of the above evaluation method.

[0022] (Embodiment) (1) Overall structure The overall configuration of an evaluation management system including an evaluation system A1 according to an embodiment and its peripheral configuration (various sensors 3 and terminals 4) will be described below with reference to Fig. 1. The evaluation system A1 evaluates layout changes related to a target space S1 (such as an office work space) of a facility 100 (for example, an office building) in response to a request from a user. A server on which the functions of the evaluation system A1 are implemented is installed, for example, outside the facility 100.

[0023] In this embodiment, as an example, the facility 100 includes a plurality of management spaces 2 whose layout may be changed. The plurality of management spaces 2 include, for example, office spaces and conference rooms. However, the number of management spaces 2 may be one. A user can use a terminal 4 (as described below) to select one or more of the plurality of management spaces 2 and set the selected management spaces 2 as target spaces S1 for evaluation of the layout change.

[0024] Terminal 4 is an information terminal used by a user. Terminal 4 is realized, for example, by a computer system having one or more processors and one or more memories. In other words, the one or more processors execute programs recorded in the memory to realize multiple functions of terminal 4. The programs may be pre-recorded in the memory, or may be provided via a telecommunications line such as the Internet, or may be recorded on a non-transitory recording medium such as a memory card and provided.

[0025] As shown in FIG. 1, the terminal 4 includes a display unit 40, an input unit 41, and a notification unit 42. The display unit 40 is a display (e.g., a liquid crystal display, etc.). The terminal 4 is, for example, a tablet terminal. The terminal 4 may be a smartphone, a laptop, a desktop personal computer, etc. Dedicated application software for communicating with the evaluation system A1 (server) is pre-installed on the terminal 4. The terminal 4 is communicably connected to a gateway within the facility 100. The terminal 4 can communicate with the server via the gateway. The communication path between the terminal 4 and the server may be a wireless path or a wired path.

[0026] The terminal 4 can receive various types of information from the evaluation system A1 (server) and display it on its own display unit 40. In particular, the display unit 40 can display an input screen G1 (see FIG. 2) for change request information, an input screen G2 (see FIG. 3) for a predetermined period for tallying the first environmental information and the second environmental information, and a result screen G3 (see FIG. 4) showing the evaluation results.

[0027] Here, as an example, it is assumed that the display unit 40 is a touch panel display. As a result, information can be input to the input screen G1 and the input screen G2 by a tap operation or the like by the user. However, input operations may also be performed using a mouse pointer, a keyboard, or the like.

[0028] The input unit 41 accepts input of change request information and information regarding a predetermined period from the user via the input screen G1 or input screen G2, and transmits the input information to the evaluation system A1 (server) via the gateway.

[0029] The notification unit 42 notifies the user of the evaluation result received from the evaluation system A1 (server) via the result screen G3.

[0030] (2) Evaluation system configuration The configuration of the evaluation system A1 will be described in detail below.

[0031] The evaluation system A1 includes a processing unit 10, a storage unit 15, a first communication unit F1, and a second communication unit F2.

[0032] The first communication unit F1 has a communication interface for individually communicating with one or more (here, three) sensors 3 via a gateway. The communication method of the first communication unit F1 is assumed to be wireless, but may also be wired.

[0033] The second communication unit F2 has a communication interface for communicating with the terminal 4 used by the user via the gateway. The communication method of the second communication unit F2 is assumed to be wireless, but may also be wired.

[0034] The storage unit 15 is, for example, a non-volatile memory. As shown in Fig. 1, the storage unit 15 stores correspondence relationship information D1 in advance. As will be described in detail later, the correspondence relationship information D1 is information in which threshold values ​​(e.g., amounts of change) for one or more environmental elements are associated with multiple change requests.

[0035] 1, the storage unit 15 stores first environmental information B1 including the detection results received from the sensor 3, and second environmental information B2. The storage unit 15 also stores change request information C1 including a change request for the layout received from the terminal 4.

[0036] The processing unit 10 is realized, for example, by a computer system having one or more processors and one or more memories. That is, the one or more processors execute a program recorded in the memory, thereby realizing the multiple functions of the processing unit 10. The program may be pre-recorded in the memory, may be provided via a telecommunications line such as the Internet, or may be provided by being recorded on a non-transitory recording medium such as a memory card.

[0037] The processing unit 10 includes an environment acquisition unit 11, a need acquisition unit 12, an evaluation processing unit 13, and an output unit 14 (see FIG. 1).

[0038] The environment acquisition unit 11 acquires first environment information B1 and second environment information B2. The first environment information B1 includes one or more environment elements in the target space S1 before the layout (such as seats) is changed. The second environment information B2 includes one or more environment elements after the layout (such as seats) is changed.

[0039] Specifically, one or more environmental elements in each of the first environmental information B1 and the second environmental information B2 are elements based on the detection results detected by one or more sensors 3 installed in the target space S1. Here, as an example, the evaluation management system includes three sensors 3: an environmental sensor 31, a CO2 sensor 32, and a human presence sensor 33. When there are multiple management spaces 2, it is preferable that the three sensors 3 be installed in each of the multiple management spaces 2.

[0040] The one or more environmental elements in each of the first environmental information B1 and the second environmental information B2 include at least one of the temperature, humidity, noise, congestion level, and carbon dioxide (CO2) concentration of the target space S1. As an example, it is assumed here that each of the first environmental information B1 and the second environmental information B2 includes the environmental elements of the temperature, humidity, noise, congestion level, and carbon dioxide (CO2) concentration of the target space S1, as well as the environmental element of the utilization rate (six environmental elements in total). These six environmental elements are elements based on the detection results detected by the three sensors 3.

[0041] Specifically, the environmental factors of temperature, humidity, and noise are obtained based on the detection results detected by the environmental sensor 31. The environmental sensor 31 includes a temperature sensor, a humidity sensor, and a noise sensor. The environmental sensor 31 transmits a detection signal indicating the detection result to the first communication unit F1 of the evaluation system A1.

[0042] The environmental factor of carbon dioxide (CO2) concentration is obtained based on the detection result detected by the CO2 sensor 32. The CO2 sensor 32 transmits a detection signal indicating the detection result to the first communication unit F1 of the evaluation system A1.

[0043] The environmental factors of the congestion level and utilization rate are obtained based on the detection results detected by the human presence sensor 33. Specifically, the human presence sensor 33 transmits a detection signal indicating that a human body has been detected within its own detection range to the first communication unit F1 of the evaluation system A1. The congestion level is the proportion of people (employees, etc.) present in the target space S1, and is calculated using the detection results of the human presence sensor 33. The utilization rate is the proportion of the number of people using the target space S1 out of the total number of employees, and is calculated using the detection results of the human presence sensor 33. It is assumed that the congestion level and utilization rate are calculated by the processing unit 10 based on the detection results of the human presence sensor 33, but they may also be calculated by the human presence sensor 33 and the calculation results transmitted to the first communication unit F1.

[0044] The processing unit 10 calculates actual values ​​of six environmental elements, namely, temperature, humidity, noise, CO2 concentration, congestion level, and utilization rate, based on the detection results from the three sensors 3 received via the first communication unit F1. The processing unit 10 then associates the actual values ​​of the environmental elements based on the detection results from each sensor 3 with the date and time when the detection results were received, ID information of the corresponding sensor 3, and information about the location (management space 2) where the corresponding sensor 3 is located, and stores (memorizes) the results in the storage unit 15. Here, as an example, the first communication unit F1 periodically receives the detection results from the three sensors 3 (for example, every few minutes, 30 minutes, 1 hour, or 24 hours), and the processing unit 10 calculates the actual values ​​of the environmental elements each time and stores (memorizes) the results in the storage unit 15.

[0045] The processing unit 10 acquires, for example, from the terminal 4, information about the time when a layout change occurred (hereinafter referred to as the "time when the change occurred"). The processing unit 10 acquires, via the second communication unit F2, a "predetermined period" input into an input screen G2 (see FIG. 3) that can be displayed on the display unit 40 of the terminal 4, and identifies the time when the change occurred based on the information. The environment acquisition unit 11 acquires first environment information B1, which includes performance data before the time when the change occurred, from the performance values ​​(performance data) of the six environmental elements stored in the storage unit 15. The environment acquisition unit 11 also acquires second environment information B2, which includes performance data after the time when the change occurred, from the performance values ​​(performance data) of the six environmental elements stored in the storage unit 15. In short, the environment acquisition unit 11 acquires the first environment information B1 and the second environment information B2 from the storage unit 15.

[0046] 3 shows a conceptual diagram of an input screen G2 for inputting information for identifying the change occurrence point. The input screen G2 can be displayed on the display unit 40 of the terminal 4 when the user uses the terminal 4 to request the evaluation system A1 to perform an evaluation of a layout change. The input screen G2 is a screen for inputting (selecting) a predetermined period for aggregating the first environmental information and the second environmental information.

[0047] Specifically, input screen G2 includes a display area displaying the message "Please enter the period before and after the layout change." Input screen G2 also includes, as input areas, an input field R3 for inputting a predetermined period "before the change" and an input field R4 for inputting a predetermined period "after the change." Input screen G2 also includes a confirm button R5 as an operation area. Here, as an example, it is assumed that input into input fields R3 and R4 is performed by tapping or the like to display a pull-down list, and selecting a specific year from multiple selectable years displayed on the list. Alternatively, a format may be adopted in which numerical values ​​(years) are directly input into input fields R3 and R4.

[0048] In the example of FIG. 3, "2023" is entered (selected) in input field R3, and "2024" is entered (selected) in input field R4. When the user taps the confirm button R5 with "year" selected in input fields R3 and R4, terminal 4 transmits the information on the "year" selected in input fields R3 and R4 to evaluation system A1. In this example, based on the "year" information received from terminal 4, processing unit 10 determines the predetermined period "before the change" to be one year in 2023, and the predetermined period "after the change" to be one year in 2024. That is, in this example, processing unit 10 determines "January 1, 2024, 00:00:00" as the time point when the change occurred.

[0049] In this example, it is assumed that the predetermined period is input only in years, but it may also be possible to input (select) it in "year / month" or "year / month / day", etc. Also, here it is assumed that the predetermined period "before the change" and the predetermined period "after the change" are the same period (one year), but they may also be different periods. For example, the predetermined period "before the change" may be one year and the predetermined period "after the change" may be one month.

[0050] 3, the environment acquisition unit 11 acquires, from the storage unit 15, first environment information B1 including performance data of environmental elements received from the sensor 3 during the year 2023, before the time point at which the change occurred. The environment acquisition unit 11 also acquires, from the storage unit 15, second environment information B2 including performance data of environmental elements received from the sensor 3 during the year 2024, after the time point at which the change occurred.

[0051] The request acquisition unit 12 acquires change request information C1 including a change request for a layout. The change request is input by a user, for example, via the terminal 4. The request acquisition unit 12 acquires the change request information C1 including the change request from the terminal 4 via the second communication unit F2.

[0052] Specifically, the change request information C1 is input through an input screen G1 (see FIG. 2). The input screen G1 can be displayed on the display unit 40 of the terminal 4 when the user makes an input request using the terminal 4 at any timing before the layout change (or at any timing after the layout change).

[0053] Specifically, the input screen G1 includes a display area displaying the message "Please enter your request." The input screen G1 also includes, as input areas, an input field R11 for inputting the "location of improvement," an input field R12 for inputting the "request item," and an input field R13 for inputting the "degree of improvement." The input screen G1 also includes a confirm button R2 as an operation area. Here, as an example, it is assumed that input into each of the input fields R11 to R13 is performed by tapping or the like to display a pull-down list, and selecting one from multiple options displayed on the list. However, a format in which characters and numbers are directly input into the input fields R11 to R13 may also be adopted. When characters are directly input, the processing unit 10 may have a function of extracting a specific keyword from the input character string.

[0054] 2, the change request includes the location to be improved (i.e., the target space S1 for layout change), the desired items for the location to be improved, and the degree of improvement for the desired items. That is, the change request includes information that designates one or more (one in FIG. 2) management spaces 2 out of the multiple management spaces 2 as the target space S1 (improvement location).

[0055] In the example of FIG. 2, "Office Space" is input (selected) in input field R11, "Want to increase communication" is input (selected) in input field R12, and "3" is input (selected) in input field R13. When the user taps the OK button R2 with the improvement location, desired item, and degree of improvement selected in input fields R11 to R13, the terminal 4 transmits a change request (change request information C1) including the selected improvement location, desired item, and degree of improvement to the evaluation system A1. As a result, the request acquisition unit 12 acquires the change request information C1 including the improvement location of the layout (target space S1), the desired item for the improvement location, and the degree of improvement for the desired item. The change request information C1 is stored (memorized) in the memory unit 15.

[0056] In this embodiment, as an example, there are two candidate areas that can be input (selected) as the improvement location (target space S1): a conference room and an office space. However, the candidate areas for improvement are not limited to conference rooms and office spaces. In addition, the number of candidate areas for improvement is not particularly limited. In some offices, the management space 2 may only consist of office spaces, so it may not be possible to select an improvement location.

[0057] In this embodiment, as an example, there are two candidate items that can be input (selected) as desired items: "I want to increase communication" and "I want to increase the number of users." Communication refers to interactions between employees within the selected improvement location. The number of users refers to the number of employees who use the selected improvement location. The desired item candidates are not limited to these. Furthermore, there is no particular limit to the number of desired item candidates.

[0058] In this embodiment, as an example, the possible candidates for the degree of improvement that can be input (selected) are three levels, "1" to "3." The degree of improvement is the degree of improvement for the selected desired item at the selected improvement location. For example, an improvement level of "3" means that a large improvement is desired for the desired item, an improvement level of "1" means that a small improvement is desired for the desired item, and an improvement level of "2" means that an improvement is desired that is intermediate between "1" and "3." The degree of improvement is not limited to three levels, but may be two levels or four or more levels. Furthermore, the degree of improvement is not limited to numerical input such as "1" to "3," but may be character input such as "large," "medium," or "small."

[0059] Table 1 below shows an example of a combination of improvement locations, desired items, and improvement levels that a user can input through input screen G1. As shown in Table 1, if there are two improvement locations and two types of desired items, the user can sequentially input (select) all combinations on input screen G1. As a result, a change request (change request information C1) including multiple combinations such as those shown in Table 1 is sent to evaluation system A1.

[0060] [Table 1]

[0061] The evaluation system A1 may be capable of accepting input of multiple desired items and the desired degree of improvement for each desired item on the input screen G1. For example, a user may simultaneously input "I want to increase communication" and "3" and "I want to increase users" and "1" on the input screen G1. In short, a change request may include one or more desired items and the desired degree of improvement for each of the one or more desired items.

[0062] The evaluation processing unit 13 derives an evaluation result for the layout before and after the layout change. The evaluation processing unit 13 obtains difference information between the first environmental information B1 and the second environmental information B2.

[0063] As an example, the evaluation processing unit 13 calculates the amount of change in the second environmental information B2 relative to the first environmental information B1 for each of one or more environmental elements as difference information. More specifically, for example, the evaluation processing unit 13 tallies one or more environmental elements in each of the first environmental information B1 and the second environmental information B2 over a predetermined period. Then, the evaluation processing unit 13 calculates the difference between the tallied results of the first environmental information B1 and the second environmental information B2 as difference information (amount of change) of the second environmental information B2 relative to the first environmental information B1.

[0064] For example, in the example of FIG. 3, the evaluation processing unit 13 aggregates data for one year (predetermined period) up to 2023 for the actual values ​​of six environmental elements included in the first environmental information B1, and calculates a representative value (e.g., average value) of the actual values ​​of each environmental element. That is, the evaluation processing unit 13 calculates the annual average (annual mean) of the actual values ​​of each environmental element before the layout change. Also, in the example of FIG. 3, the evaluation processing unit 13 aggregates data for one year (predetermined period) up to 2024 for the actual values ​​of six environmental elements included in the second environmental information B2, and calculates a representative value (e.g., average value) of the actual values ​​of each environmental element. That is, the evaluation processing unit 13 calculates the annual average (annual mean) of the actual values ​​of each environmental element after the layout change. Note that if the predetermined period is one month, a monthly average (monthly mean) may be applied.

[0065] Table 2 below shows an example of the actual values ​​before aggregation for each environmental element in the "conference room" before the layout change. Table 3 below shows an example of the actual values ​​(annual average) after aggregation for each environmental element in the "conference room" before the layout change. The numerical values ​​of each actual value are replaced with an asterisk. The "time" in Table 2 indicates the date and time when the evaluation system A1 received the detection results from the sensor 3.

[0066] [Table 2]

[0067] [Table 3]

[0068] Table 4 below shows an example of the actual values ​​before aggregation for each environmental element in the "conference room" after the layout change. Table 5 below shows an example of the actual values ​​(annual average) after aggregation for each environmental element in the "conference room" after the layout change. The numerical values ​​of each actual value are replaced with an asterisk. The "time" in Table 4 indicates the date and time when the evaluation system A1 received the detection results from the sensor 3.

[0069] [Table 4]

[0070] [Table 5]

[0071] Although explanation using a table will be omitted, the evaluation processing unit 13 can also tally up the actual values ​​of each environmental element in the "office space" before and after the layout change in response to a change request from the user.

[0072] Table 6 below shows an example of the result of calculation by the evaluation processing unit 13 of the difference between the tabulated results (annual average) of the first environmental information B1 and the tabulated results (annual average) of the second environmental information B2 as the amount of change (difference information) of the second environmental information B2 relative to the first environmental information B1. In this example, the amount of change is expressed as a percentage.

[0073] [Table 6]

[0074] The evaluation processing unit 13 determines a threshold value according to the change request information C1. The evaluation processing unit 13 derives an evaluation result based on the result of comparing the difference information with the threshold value. Here, the evaluation processing unit 13 identifies, from among the multiple change requests in the correspondence relationship information D1, a change request that matches the change request in the change request information C1 acquired by the request acquisition unit 12. Then, the evaluation processing unit 13 extracts threshold values ​​(amounts of change) for one or more environmental elements associated with the identified change request.

[0075] The correspondence information D1 will be described in detail below. The correspondence information D1 is information in which thresholds (amounts of change) for one or more environmental elements are associated with multiple change requests, and is pre-stored in the storage unit 15. Specifically, each request item is associated with a degree of improvement from "1" to "3," and each degree of improvement is further associated with thresholds (amounts of change) for six environmental elements.

[0076] Table 7 below shows the correspondence information D1 in data table format. The correspondence information D1 includes thresholds (amounts of change) used by the evaluation processing unit 13, and can also be considered threshold information (threshold table). In the desired items in Table 7, "I want to increase communication" is abbreviated as "Ko (increase)" and "I want to increase users" is abbreviated as "Users (increase)". Where a blank (-) is set as the threshold, it means that any amount of change is acceptable.

[0077] [Table 7]

[0078] The correspondence information D1 is not limited to being stored in the storage unit 15 in a data table format as shown in Table 7. Furthermore, the numerical values ​​of the thresholds (amounts of change) shown in Table 7 are merely examples, and the thresholds are not limited to these numerical values.

[0079] As shown in Table 7, the correspondence information D1 associates each of a plurality of improvement degrees with thresholds (amounts of change) for one or a plurality of (six in the example of Table 7) environmental elements.

[0080] As a plurality of candidate desired items selectable in the pull-down list of the input field R12 of the input screen G1, for example, a plurality of (two) desired items included in this correspondence relationship information D1 may be displayed. Also, as a plurality of candidate improvement degrees selectable in the pull-down list of the input field R13 of the input screen G1, for example, improvement degrees "1" to "3" included in this correspondence relationship information D1 may be displayed.

[0081] The phrase "the evaluation processing unit 13 identifies, from among the multiple change requests in the correspondence information D1, a change request that matches a change request in the change request information C1 acquired by the request acquisition unit 12" means, for example, "identifying a change request that matches a combination of a request item and an improvement level in the change request information C1 acquired by the request acquisition unit 12." Specifically, for example, assume that the request item and the improvement level in the change request information C1 acquired by the request acquisition unit 12 are "want to increase communication" and "3." The evaluation processing unit 13 references the correspondence information D1 to identify a change request that matches this combination (for example, the third change request from the top of the six change requests in Table 7, marked with an asterisk (*)). Then, the evaluation processing unit 13 extracts thresholds of environmental factors associated with the identified change request (in this case, a temperature threshold of "+0.5%," a humidity threshold of "+10%," a noise threshold of "+3%, a CO2 threshold of "+5%, a congestion threshold of "+5%, and a utilization rate of "-").

[0082] The evaluation processing unit 13 compares the calculated change amount for each of one or more environmental elements with the change amount, which is a threshold extracted from the correspondence information D1. The evaluation processing unit 13 determines whether the calculated change amount is equal to or greater than the threshold, and derives an evaluation result based on the determination result. Specifically, for example, assume that the improvement location, desired item, and improvement level in the change request information C1 acquired by the request acquisition unit 12 are "conference room," "want to increase communication," and "3." The evaluation processing unit 13 determines whether the changes in the temperature, humidity, noise, CO2, congestion level, and utilization rate of the "conference room" in Table 6 are equal to or greater than the temperature threshold "+0.5%," the humidity threshold "+10%, the noise threshold "+3%, the CO2 threshold "+5%, the congestion level threshold "+5%, and the utilization rate "-," respectively.

[0083] For example, if the change amounts for all environmental elements are equal to or greater than the corresponding thresholds, the evaluation processing unit 13 evaluates the layout change as "successful." In the example of the change amounts for the "conference room" shown in the top row of Table 6, the temperature, humidity, noise, CO2, congestion level, and utilization rate are all equal to or greater than the thresholds corresponding to the change request marked with an (*) in the third row from the top in Table 7, so the layout change is evaluated as "successful."

[0084] Conversely, if there is one or more environmental elements whose change amount is less than the threshold, the evaluation processing unit 13 evaluates the layout change as a "failure." In the example of the change amounts of temperature, humidity, noise, CO2, congestion level, and utilization rate for the "office space" shown in the bottom row of Table 6, there is one or more environmental elements whose change amount is less than the threshold corresponding to the change request marked with an (*) in the third position from the top in Table 7, so the layout change is evaluated as a "failure."

[0085] As described above, if the amount of change for all environmental elements is equal to or greater than the threshold, the layout change is evaluated as "successful." For example, if there are only one or two environmental elements whose amount of change is less than the threshold, the change may be tolerated and evaluated as "successful." Furthermore, depending on the type of environmental element, if the amount of change is less than the threshold, the change may be evaluated as "successful," and if the amount of change is equal to or greater than the threshold, the change may be evaluated as "failed."

[0086] In the above example, it is assumed that the correspondence relationship information D1 (threshold table) shown in Table 7 is commonly used whether the location of the requested change is a "conference room" or an "office space." However, different threshold tables may be prepared in advance for each location to be improved, and thresholds may be extracted from the threshold tables corresponding to each location to be improved.

[0087] The output unit 14 outputs the evaluation result. In this embodiment, the output unit 14 executes a display process to output and display the evaluation result on the display unit 40. The evaluation result may include, for example, information indicating whether the layout change was "successful" or "failed." The output unit 14 generates display image data related to the evaluation result and transmits it to the terminal 4 via the second communication unit F2.

[0088] FIG. 4 is a conceptual diagram of a result screen G3 displayed on the display unit 40, showing the evaluation results. In the example of FIG. 4, the result screen G3 includes a message stating "Layout Change Success." The user can see through the result screen G3 that the layout change has been achieved as desired. Preferably, the output unit 14 displays not only a message indicating "success" or "failure" as shown in the result screen G3, but also a report including more detailed evaluation results on the display unit 40. In this case, for example, if the layout change is evaluated as "failed," the report may include information indicating which environmental factors caused the evaluation. The report may also include information such as those shown in Tables 1 to 7. The report may also include suggestion information. For example, if the layout change is evaluated as "failed" due to the environmental factor "utilization rate," the suggestion information may include a message suggesting adjustments to the layout to increase the "utilization rate."

[0089] (3) Operation explanation The operation of the evaluation system A1 will be described below with reference to the flowchart shown in Fig. 5 and the sequence diagram shown in Fig. 6. Note that the flowchart shown in Fig. 5 and the sequence diagram shown in Fig. 6 are merely examples of the operation flow of the evaluation system A1, and the order of processing may be changed as appropriate, and processing may be added or omitted as appropriate.

[0090] First, before the evaluation system A1 is put into operation in the office of the facility 100, the correspondence information D1 (threshold table) is set (step ST1 in FIG. 5). The correspondence information D1 may be set in advance by, for example, a manufacturer / seller of the evaluation system A1. However, when the evaluation system A1 is introduced into the office of the facility 100, the user may be able to register / change the correspondence information D1 as appropriate via the terminal 4.

[0091] When the evaluation system A1 starts operating in the office of the facility 100, the evaluation system A1 receives detection results (detection signals) from each sensor 3 as needed (step ST2 in FIG. 5). That is, in FIG. 6, the environmental sensor 31, the CO2 sensor 32, and the human presence sensor 33 each transmit a detection signal to the first communication unit F1 of the evaluation system A1 as needed. When the evaluation system A1 receives the detection signal, the processing unit 10 calculates actual values ​​of the environmental elements (temperature, humidity, noise, CO2 concentration, congestion level, and utilization rate). The processing unit 10 then associates the actual values ​​with the date and time when the detection signal was received, the ID information of the corresponding sensor 3, information on the installation location of the corresponding sensor 3, and the like, and stores (memorizes) the results in the memory unit 15 (step ST11 in FIG. 6).

[0092] The processing of step ST2 in FIG. 5 and step ST11 in FIG. 6 can be performed at any time before or after changing the layout.

[0093] Next, the evaluation system A1 acquires change request information C1 (step ST3 in FIG. 5: request acquisition process). That is, in FIG. 6, when a user inputs a change request on the terminal 4 (on its input screen G1) (step ST12 in FIG. 6), the terminal 4 transmits change request information C1 (change request signal) including the change request to the second communication unit F2 of the evaluation system A1. The change request includes, for example, an improvement location "conference room," a request item "want to increase communication" with an improvement level of "3" for the "conference room," and a request item "want to increase users" with an improvement level of "1" for the "conference room." The change request also includes, for example, an improvement location "office space," a request item "want to increase communication" with an improvement level of "3," and a request item "want to increase users" with an improvement level of "2" for the "office space." The processing unit 10 of the evaluation system A1 stores (memorizes) the change request information C1 including the change request in the memory unit 15 (step ST13 in FIG. 6).

[0094] 5 and steps ST12 and ST13 in Fig. 6 are assumed to be executed before the layout is changed, but may be executed after the layout is changed. In other words, the timing for inputting a change request from the user may be before or after the layout change is actually implemented in the management space 2 of the office.

[0095] Thereafter, the evaluation system A1 acquires the first environmental information B1 and the second environmental information B2 (step ST4 in FIG. 5: environment acquisition process). That is, in FIG. 6, when the user inputs the period before and after the layout change on the terminal 4 (on its input screen G2), the terminal 4 generates an output request signal for requesting output of the change result (i.e., output of the evaluation result) (step ST14 in FIG. 6). The terminal 4 transmits the output request signal including the period before and after the layout change to the second communication unit F2 of the evaluation system A1. As a result, the processing unit 10 of the evaluation system A1 acquires the first environmental information B1 and the second environmental information B2 by reading, from the storage unit 15, the performance data of the environmental elements corresponding to the periods before and after the layout change, respectively. Then, the processing unit 10 of the evaluation system A1 executes a process for deriving the evaluation result (step ST15 in FIG. 6: evaluation process).

[0096] This evaluation process corresponds to steps ST5 to ST7 in Fig. 5. That is, the processing unit 10 of the evaluation system A1 calculates the amount of change in each environmental element before and after the layout change (step ST5 in Fig. 5). The processing unit 10 also identifies a threshold value for judgment from the change request information C1 in the correspondence relationship information D1 (threshold value table) (step ST6 in Fig. 5). The processing unit 10 then compares the amount of change with the threshold value to derive an evaluation result (step ST7 in Fig. 5). For example, if the amount of change for all environmental elements is equal to or greater than the threshold value, the processing unit 10 evaluates that the layout change of the improvement location has been successful, and if there is one or more environmental elements whose amount of change is less than the threshold value, the processing unit 10 evaluates that the layout change of the improvement location has been unsuccessful.

[0097] If the change request specifies multiple improvement locations (target spaces S1), such as a "conference room" and an "office space," the evaluation system A1 executes the environment acquisition process (step ST4) and evaluation process (steps ST5 to ST7) for each of the specified improvement locations.

[0098] Finally, the evaluation system A1 outputs the evaluation result (step ST8 in FIG. 5: output process). That is, in FIG. 6, the processing unit 10 of the evaluation system A1 transmits the evaluation result to the terminal 4 via the second communication unit F2. In the terminal 4, the evaluation result is displayed on the screen of the display unit 40 (step ST16 in FIG. 6).

[0099] As described above, the evaluation system A1 according to the embodiment automatically evaluates a layout change taking into account a threshold value according to the change request (from the user) and difference information between the actual layout before and after the change. Therefore, the evaluation system A1 can easily provide results based on a more quantitative evaluation of the layout change. Furthermore, the evaluation results are output and displayed on the display unit 40, allowing the user to visually recognize the evaluation results, improving convenience.

[0100] (4) Variations The following are examples of modifications: Each of the modifications described below can be applied in appropriate combination with the above embodiment or other modifications.

[0101] The same functions as those of the evaluation system A1 according to the above embodiment may be embodied in an evaluation method, a computer program, or a non-transitory recording medium on which a computer program is recorded.

[0102] The evaluation system A1 of the present disclosure includes a computer system. The computer system is primarily composed of a processor and memory as hardware. The processor executes a program stored in the memory of the computer system to realize the functions of the evaluation system A1 of the present disclosure. The program may be pre-stored in the memory of the computer system, provided via a telecommunications line, or provided on a non-transitory recording medium readable by the computer system, such as a memory card, optical disk, or hard disk drive. The processor of the computer system is composed of one or more electronic circuits, including a semiconductor integrated circuit (IC) or a large-scale integrated circuit (LSI). The integrated circuits, such as ICs and LSIs, are referred to by different names depending on the degree of integration, and include integrated circuits called system LSIs, very large-scale integrations (VLSIs), and ultra-large-scale integrations (ULSIs). Furthermore, field-programmable gate arrays (FPGAs), which are programmable after the LSI is manufactured, or logic devices that allow the reconfiguration of internal connections or circuit partitions within the LSI, can also be used as processors. The electronic circuits may be integrated into one chip or distributed across multiple chips. The chips may be integrated into one device or distributed across multiple devices. The computer system referred to here includes a microcontroller having one or more processors and one or more memories. Therefore, the microcontroller is also composed of one or more electronic circuits including a semiconductor integrated circuit or a large-scale integrated circuit.

[0103] Furthermore, it is not essential that the multiple functions of the evaluation system A1 be concentrated in one housing. For example, the components of the evaluation system A1 may be distributed across multiple housings.

[0104] Conversely, multiple functions of the evaluation system A1 may be integrated into one housing. Furthermore, at least some of the functions of the evaluation system A1, for example, some of the functions of the evaluation system A1 may be realized by the cloud (cloud computing) or the like.

[0105] In the above embodiment, the performance data of environmental elements may need to be accumulated to a certain extent not only before the layout change but also after the layout change in order to be aggregated on a monthly or yearly basis. In other words, in the above embodiment, to obtain the evaluation results of the layout change, it may take months or years from the time the user actually changes the layout of the office space, etc., until a certain amount of performance data of environmental elements after the layout change is accumulated. However, the evaluation system A1 does not necessarily aggregate performance data on a monthly or yearly basis. For example, the evaluation system A1 may aggregate performance data before the layout change on a monthly or yearly basis, while accumulating performance data after the layout change for one to several days to calculate the amount of change. Alternatively, the evaluation system A1 may calculate the amount of change for at least one of the performance data before the layout change and the performance data after the layout change using only performance data based on the detection results received once from each sensor 3.

[0106] In the above embodiment, the evaluation result is output (notified) to the user by a screen display on the display unit 40. However, the output of the evaluation result is not limited to a screen display output. For example, the evaluation result may be output as an audio output in addition to (or instead of) a screen display output. Specifically, an audio message saying "Layout change successful" may be output from a speaker attached to the terminal 4.

[0107] In the above embodiment, the desired item and the degree of improvement are input (selected) separately in separate input fields. However, input of the degree of improvement may not be necessary. For example, the desired item and the degree of improvement may be input (selected) as a set in one input field. In this case, candidates such as "I want to increase communication (large)," "I want to increase communication (medium)," and "I want to increase communication (small)" may be displayed in a pull-down list. Furthermore, candidates such as "I want to increase users (large)," "I want to increase users (medium)," and "I want to increase users (small)" may be displayed in a pull-down list. In other words, the desired item itself may include words corresponding to the degree of improvement.

[0108] In the above embodiment, the degree of improvement of the change request that is input is in three stages, from "1" to "3." However, the degree of improvement may be expressed in other ways, such as a percentage (50% is a normal improvement, the closer the percentage is to 100%, the greater the desired improvement, and the closer the percentage is to 0%, the smaller the desired improvement, etc.).

[0109] (summary) The above-described embodiments and the like disclose the following aspects.

[0110] An evaluation system (A1) according to a first aspect evaluates a layout change for a target space (S1) of a facility (100).
