Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the conventional technology, control of an air conditioner or the like is performed after a change occurs in the physiological information. Therefore, even if an attempt is made to realize an environment in which an individual staying indoors does not feel stress, the control of the air conditioner or the like is executed after a change occurs in the physiological information of the individual, that is, after the individual feels stress, and the control of the indoor environment is delayed.

[0005] One aspect of the disclosed technology aims to provide an environmental control system that can realize an indoor environment in which the stress received by an individual is suppressed as much as possible.

Means for Solving the Problems

[0006] One aspect of the disclosed technology is exemplified by the following environmental control system: This environmental control system comprises a first control unit that controls the environment of a room in which an individual is staying; a measurement unit that measures values ​​indicating the environment of the room; an environmental model that is constructed using the correspondence between the individual's stress-dependent behavioral patterns and the values ​​indicating the environment as input data, and outputs a target value to suppress the individual's stress when a time-series change in the values ​​indicating the environment is input; and a second control unit that controls the first control unit so that the values ​​indicating the environment measured by the measurement unit approach the target value obtained by inputting the time-series change in the values ​​indicating the environment into the environmental model.

[0007] According to the above-described environmental control system, by inputting the time-series changes in the values ​​representing the environment into the environmental model, a target value for suppressing the individual's stress can be obtained. Then, by controlling the first control unit so that the values ​​representing the environment measured by the measurement unit approach the target value, an indoor environment in which the individual's stress is suppressed as much as possible can be realized.

[0008] In the above environmental control system, the value indicating the environment includes the room temperature, the measurement unit includes a temperature sensor for measuring the room temperature, the first control unit includes an air conditioner for controlling the room temperature, and the environmental model may include a room temperature model that constructs a correspondence between an individual's stress-related behavioral patterns and the room temperature as input data, and outputs a target room temperature value to suppress the individual's stress when a time-series change in the room temperature is input. The second control unit then adjusts the room temperature measured by the temperature sensor to approach the target room temperature value obtained by inputting the time-series change in the room temperature into the room temperature model. The above-mentioned air conditioner may be controlled. By controlling the air conditioner in this way, a room temperature that is less likely to cause stress to the individual can be maintained.

[0009] In the above-described environmental control system, the value indicating the environment includes the humidity in the room, the measurement unit includes a humidity sensor for measuring the humidity, the first control unit includes a humidifier for controlling the humidity in the room, and the environmental model may include a humidity model that is constructed using the correspondence between an individual's stress-related behavioral patterns and the humidity as input data, and outputs a target humidity value that suppresses the individual's stress when a time-series change in humidity is input. Furthermore, the second control unit may control the humidifier so that the humidity measured by the humidity sensor approaches the target humidity value obtained by inputting the time-series change in humidity into the humidity model. By controlling the humidifier in this way, it is possible to maintain a humidity level that makes the individual less likely to feel stressed.

[0010] In the above-described environmental control system, the value indicating the environment includes the illuminance in the room, the measurement unit includes an illuminance sensor for measuring the illuminance, the first control unit includes lighting fixtures for controlling the illuminance in the room, and the environmental model may include an illuminance model that constructs a correspondence between the individual's stress-related behavioral patterns and the illuminance as input data, and outputs a target illuminance value that suppresses the individual's stress when a time-series change in the illuminance is input. Furthermore, the second control unit may control the lighting fixtures so that the illuminance measured by the illuminance sensor approaches the target illuminance value obtained by inputting the time-series change in the illuminance into the illuminance model. By controlling the lighting fixtures in this way, it is possible to maintain an illuminance level that makes the individual less likely to feel stressed.

[0011] In the above-described environmental control system, the value indicating the environment includes a value indicating the loudness of sound in the room, the measurement unit includes a microphone for measuring the loudness of sound, the first control unit includes a sound insulation unit that suppresses the intrusion of external sound into the room, and the environmental model may include a noise model that constructs a correspondence between the behavioral pattern corresponding to the individual's stress and the value indicating the loudness of sound as input data, and outputs a target value for the loudness of sound that suppresses the individual's stress when a time-series change in the value indicating the loudness of sound is input. Furthermore, the second control unit may control the sound insulation unit so that the value indicating the loudness of sound measured by the microphone approaches the target value of the loudness of sound obtained by inputting the time-series change in the value indicating the loudness of sound into the noise model. By controlling the sound insulation unit in this way, the loudness of external sounds intruding can be suppressed to a range in which the individual does not feel stressed.

[0012] In the above-described environmental control system, the value indicating the environment includes the atmospheric pressure inside the room, the measurement unit includes a pressure sensor for measuring the atmospheric pressure, the first control unit includes a pressure adjustment device for controlling the atmospheric pressure inside the room, and the environmental model may include a pressure model that is constructed using the correspondence between the individual's stress-dependent behavioral patterns and the atmospheric pressure as input data, and outputs a target atmospheric pressure value that suppresses the individual's stress when a time-series change in atmospheric pressure is input. Furthermore, the second control unit may control the pressure adjustment device so that the atmospheric pressure measured by the pressure sensor approaches the target atmospheric pressure value obtained by inputting the time-series change in atmospheric pressure into the pressure model. By controlling the pressure adjustment device in this way, it is possible to maintain an atmospheric pressure that makes the individual less likely to feel stressed.

[0013] The disclosed technology can also be understood from the perspective of environmental control methods and environmental control programs. [Effects of the Invention]

[0014] According to the disclosed technology, it is possible to create an indoor environment in which the stress experienced by individuals is minimized as much as possible. It is.

Modes for Carrying Out the Invention

[0016] <Application Example> Hereinafter, application examples of the present invention will be described with reference to the drawings. The present invention is applied to, for example, an environmental control system 1 as shown in an example in FIG. 1. The environmental control system 1 includes an air conditioner 11, a temperature sensor 11A, a humidifier 12, a humidity sensor 12A, a lighting fixture 13, an illuminance sensor 13A, a camera 200A, and a control device 100. The air conditioner 11, the humidifier 12, and the lighting fixture 13 are collectively referred to as environmental devices 20. Also, the temperature sensor 11A, the humidity sensor 12A, and the illuminance sensor 13A are collectively referred to as environmental sensors 20A. Note that the environmental devices 20 and the environmental sensors 20A are installed in the room 10, but the installation location of the control device 100 is not limited as long as it can communicate with the environmental devices 20 and the environmental sensors 20A. The environmental control system 1 is an example of an "environmental control system". The environmental device 20 is an example of a "first control unit". The control device 100 is an example of a "second control unit". The environmental sensor 20A is an example of a "measurement unit".

[0017] Based on an image of the user 200 captured by the camera 200A, the control device 100 acquires an action pattern that the user 200 takes when feeling stressed. The action pattern taken when feeling stressed can also be referred to as a "habit" that the user 200 has when feeling stressed. The control device 100 constructs an environmental model 105 by machine learning using, as input data, the correspondence relationship between the time-series change of the measured values measured by the environmental sensor 20A and the action pattern that the user 200 takes when feeling stressed. When the measured values by the environmental sensor 20A are input, the constructed environmental model 105 outputs a target value for maintaining an environment in which the user 200 does not feel stressed in the room 10. The environmental model 105 is an example of an "environmental model". The user 200 is an example of an "individual".

[0018] The control device 100 controls the environmental equipment 20 using target values ​​obtained by inputting the time-series changes of measured values ​​measured by the environmental sensor 20A over a predetermined period into the environmental model 105. The environmental control system 1 is a system that realizes an environment in room 10 in which the stress felt by the user 200 is suppressed by controlling the environmental equipment 20 using the time-series changes of measured values ​​measured by the environmental sensor 20A over a predetermined period and the environmental model 105. The measured values ​​measured by the environmental sensor 20A are an example of "values ​​that indicate the environment".

[0019] <Embodiment> The embodiments will be further described below with reference to the drawings. Figure 1 is a diagram showing an example of the environmental control system 1 according to the embodiment. Figure 2 shows each of the components of the environmental control system 1. This diagram schematically shows the network connection of the system. In the environmental control system 1, the air conditioner 11, humidifier 12, lighting fixture 13, illuminance sensor 13A, camera 200A, and control device 100 are communicated together via network N1.

[0020] Room 10 is a place where user 200 stays and performs work, study, etc. Room 10 may, for example, be a room where user 200 performs remote work. The room where remote work is performed may, for example, be user 200's own room in their home, or it may be a private room provided for remote work.

[0021] The air conditioner 11 controls the room temperature of room 10. The air conditioner 11 also includes a temperature sensor 11A, which measures the room temperature of room 10. For example, the air conditioner 11 performs cooling or heating operations while monitoring the room temperature of room 10 measured by the temperature sensor 11A, so that the room temperature of room 10 reaches the room temperature instructed by the control device 100. The air conditioner 11 also transmits the room temperature measured by the temperature sensor 11A to the control device 100 via the network N1.

[0022] The humidifier 12 controls the humidity in room 10. The humidifier 12 also includes a humidity sensor 12A, which measures the humidity in room 10. The humidifier 12 humidifies the air in room 10 while monitoring the humidity measured by the humidity sensor 12A, so that the humidity reaches the level instructed by the control device 100. When the humidifier 12 stops operating, the humidity in room 10 decreases due to the inflow of outside air, etc. The humidifier 12 also transmits the humidity measured by the humidity sensor 12A to the control device 100 via the network N1.

[0023] The lighting fixture 13 is a lighting fixture that uses fluorescent lamps or light-emitting diodes (LEDs) to illuminate the room 10. The lighting fixture 13 can change its illuminance in response to instructions from the control device 100. The illuminance sensor 13A measures the illuminance inside the room 10. The air conditioner 11, humidifier 12, and lighting fixture 13 are collectively referred to as the environmental equipment 20. In addition, the temperature sensor 11A, humidity sensor 12A, and illuminance sensor 13A are collectively referred to as the environmental sensor 20A.

[0024] Camera 200A captures the upper body of user 200, including his / her face. Camera 200A transmits the captured image to control device 100 via network N1.

[0025] Network N1 is a network that connects computers in a way that allows them to communicate with each other. Network N1 is, for example, a Local Area Network (LAN). Network N1 may be a wireless network or a wired network.

[0026] The control device 100 acquires measurement values ​​measured by the environmental sensor 20A via the network N1 and controls the environmental equipment 20 using the acquired measurement values. Figure 3 is a diagram showing the schematic configuration of the functional units of the control device 100. The control device 100 can be considered as a computer having an arithmetic unit 111 and a storage device 112, etc. The functional units shown in Figure 3 are realized, for example, by the execution of a program stored in the storage device 112 by the arithmetic unit 111. The control device 100 has an action information acquisition unit 101, an action pattern acquisition unit 102, an environmental information acquisition unit 103, a control unit 104 and an environmental model 105, but it may also have other functional units.

[0027] The behavior information acquisition unit 101 acquires images captured by the camera 200A. The behavior information acquisition unit 101 detects the positions of the user 200's face, eyes, and hands from the acquired images.

[0028] The behavior pattern acquisition unit 102 acquires the user 200's behavior patterns based on the positions of the face and hands detected by the behavior information acquisition unit 101. For example, if the user 200's hands are at the position of the user 200's head in the image acquired by the behavior information acquisition unit 101, the behavior pattern acquisition unit 102 recognizes that the user 200 is scratching their head. For example, if the user 200's hands are at the position of the user 200's eyes in the image acquired by the behavior information acquisition unit 101, the behavior pattern acquisition unit 102 recognizes that the user 200 is rubbing their eyes. Behavior patterns such as scratching the head or rubbing the eyes are thought to be behavior patterns that occur when the user 200 is experiencing some kind of stress.

[0029] The environmental information acquisition unit 103 acquires measurement values ​​measured by the environmental sensor 20A via the network N1. The environmental information acquisition unit 103 constructs an environmental model 105 by associating the acquired measurement values ​​with the behavioral patterns performed by the user 200 at the time the measurement values ​​were acquired. The constructed environmental model 105 is stored in the storage device 112.

[0030] The environmental model 105 is a model constructed by machine learning using the correspondence between measured values ​​measured by the environmental sensor 20A and the user 200's behavioral patterns at the time the measured values ​​were taken as input data. The environmental model 105 includes a room temperature model 105A, a humidity model 105B, and an illuminance model 105C. For example, the room temperature model 105A is constructed by machine learning using the correspondence between room temperature measured by the temperature sensor 11A and the user 200's behavioral patterns as input data. For example, the humidity model 105B is constructed by machine learning using the correspondence between humidity measured by the humidity sensor 12A and the user 200's behavioral patterns as input data. For example, the illuminance model 105C is constructed by machine learning using the correspondence between illuminance measured by the illuminance sensor 13A and the user 200's behavioral patterns as input data.

[0031] The environmental model 105 constructed in this manner, upon receiving input of time-series changes in measured values ​​over a predetermined period measured by the environmental sensor 20A, outputs target values ​​for controlling the environmental equipment 20 in a way that does not cause stress to the user 200.

[0032] Figure 4 shows an example of the correspondence between measured values ​​and behavioral patterns used in constructing the environmental model 105. In Figure 4, the vertical axis shows the frequency of scratching the head, which is an example of a behavioral pattern, and the horizontal axis shows the room temperature. In the example in Figure 4, it can be seen that the frequency of scratching the head increases sharply when the room temperature reaches T1. As mentioned above, the behavioral pattern of scratching the head is thought to occur when user 200 feels some kind of stress, so it is thought that user 200 feels strong stress when the room temperature exceeds T1. Therefore, when the room temperature model 105A receives a time-series change in room temperature as input, it outputs a target value for the room temperature to control the air conditioner 11 so that the room temperature in room 10 does not exceed T1, the room temperature at which user 200 feels strong stress. Note that although Figure 4 uses the relationship between the behavioral pattern of scratching the head and room temperature as an example, the same applies to other behavioral patterns and other measured values ​​(humidity, illuminance).

[0033] For example, when the environmental model 105 receives time-series data of room temperature measured by the temperature sensor 11A over a predetermined period, it outputs a target value for room temperature to the control unit 104. For example, when the environmental model 105 receives time-series data of humidity measured by the humidity sensor 12A over a predetermined period, it outputs a target value for humidity to the control unit 104. For example, when the environmental model 105 receives time-series data of illuminance measured by the illuminance sensor 13A over a predetermined period, it outputs a target value for illuminance to the control unit 104.

[0034] The control unit 104 acquires the measured values ​​measured by the environmental sensor 20A via the network N1. The control unit 104 also acquires the measured values ​​from, for example, the storage device 112 in which the environmental model 105 is stored. The system accesses the system and inputs the time-series changes of the acquired measured values ​​over a predetermined period into the environmental model 105, thereby obtaining target values ​​from the environmental model 105 that will not cause stress to the user 200. The control unit 104 controls the environmental equipment 20 using the acquired target values. By controlling the environmental equipment 20 in this way, the stress experienced by the user 200 from the surrounding environment while working or pursuing hobbies in room 10 is reduced.

[0035] The control unit 104, for example, obtains the room temperature measured by the temperature sensor 11A from the air conditioner 11. Then, the control unit 104 inputs the time-series change of the room temperature over a predetermined period to the room temperature model 105A. The control unit 104 obtains the target value of the room temperature output by the room temperature model 105A. The control unit 104 should then control the air conditioner 11 so that the room temperature of room 10 approaches the target value of the room temperature obtained from the room temperature model 105A.

[0036] The control unit 104 acquires the humidity measured by the humidity sensor 12A from the humidifier 12. The control unit 104 then inputs the time-series change of humidity over a predetermined period to the humidity model 105B. The control unit 104 acquires the target humidity value output by the humidity model 105B. The control unit 104 can then control the humidifier 12 so that the humidity in the room 10 approaches the target humidity value acquired from the humidity model 105B.

[0037] The control unit 104, for example, acquires the illuminance measured by the illuminance sensor 13A from the illuminance sensor 13A. The control unit 104 then inputs the time-series change of illuminance over a predetermined period to the illuminance model 105C. The control unit 104 acquires the target value of illuminance output by the illuminance model 105C. The control unit 104 can then control the lighting fixture 13 so that the illuminance in the room 10 approaches the target value of illuminance acquired from the illuminance model 105C.

[0038] <Processing Flow> Figure 5 is a diagram illustrating the overall processing flow of the environmental control system 1 according to this embodiment. The overall processing flow of the environmental control system 1 will be described below with reference to Figure 5.

[0039] In step S1, the control device 100 constructs an environmental model 105 using the correspondence between the measured value measured by the environmental sensor 20A and the user 200's behavior pattern at the time the measured value was measured as input data. Details of step S1 will be described later with reference to Figures 6 and 7.

[0040] In step S2, the control device 100 uses the environmental model 105 constructed in step S1 and the measured values ​​measured by the environmental sensor 20A to control the environmental equipment 20 so that the environment of room 10 does not cause stress to the user 200. Details of step S2 will be described later with reference to Figure 8.

[0041] Figures 6 and 7 illustrate an example of a processing flow for constructing the environmental model 105. Figures 6 and 7 illustrate the details of the process in step S1 of Figure 5. Figure 6 illustrates the processing flow for acquiring the measured values ​​and behavioral patterns used in constructing the environmental model 105. Figure 7 also illustrates the processing flow for constructing the environmental model 105 using the measured values ​​and behavioral patterns acquired in Figure 6. First, referring to Figure 6, an example of a processing flow for acquiring the measured values ​​and behavioral patterns used in constructing the environmental model 105 will be explained.

[0042] In step S11, the environmental information acquisition unit 103 acquires the measured values ​​measured by the environmental sensor 20A.

[0043] In step S12, the behavior information acquisition unit 101 receives images captured by the camera 200A. An image is acquired. The behavior information acquisition unit 101 detects the position of the user 200's face and hands from the acquired image. In step S13, the behavior pattern acquisition unit 102 acquires the behavior pattern of the user 200 based on the position of the face and hands detected by the behavior information acquisition unit 101.

[0044] In step S14, the environmental information acquisition unit 103 associates the measured values ​​acquired in step S11 with the behavioral patterns acquired in step S13 and stores them in the storage device 112. The processes from step S11 to step S14 are repeatedly executed at predetermined intervals.

[0045] Next, referring to Figure 7, we will explain an example of the processing flow for constructing the environmental model 105 using the measured values ​​and behavioral patterns obtained in the processing of Figure 6.

[0046] In step S15, the environmental information acquisition unit 103 reads the correspondence between the measured values ​​stored in the storage device 112 in step S14 of Figure 6 and the behavioral patterns acquired in step S13.

[0047] In step S16, the environmental information acquisition unit 103 uses the correspondence read from the storage device 112 in step S15 as input data to construct an environmental model 105 using machine learning.

[0048] In step S17, the environmental information acquisition unit 103 stores the environmental model 105 constructed in step S16 in the storage device 112.

[0049] Figure 8 shows an example of the processing flow of the indoor environment control process by the control device 100. The following description will refer to Figure 8 to explain this example of the processing flow of the indoor environment control process by the control device 100.

[0050] In step S21, the control unit 104 continuously acquires the measured values ​​measured by the environmental sensor 20A for a predetermined period of time.

[0051] In step S22, the control unit 104 accesses the storage device 112 where the environment model 105 is stored and inputs the time-series changes of the measured values ​​acquired in step S21 over a predetermined period into the environment model 105. The control unit 104 inputs, for example, the time-series changes of the room temperature measured by the temperature sensor 11A into the room temperature model 105A. The control unit 104 obtains a target value for room temperature from the room temperature model 105A in response to the input of the time-series changes of room temperature. The control unit 104 inputs, for example, the time-series changes of humidity measured by the humidity sensor 12A into the humidity model 105B. The control unit 104 obtains a target value for humidity from the humidity model 105B in response to the input of the time-series changes of humidity. The control unit 104 inputs, for example, the time-series changes of illuminance measured by the illuminance sensor 13A into the illuminance model 105C. The control unit 104 obtains a target value for illuminance from the illuminance model 105C in response to the input of the time-series changes of illuminance.

[0052] In step S23, the control unit 104 controls the environmental equipment 20 so that the measured value measured by the environmental sensor 20A approaches the target value acquired in step S22. For example, the control unit 104 controls the air conditioner 11 so that the room temperature in room 10 approaches the target room temperature acquired in step S22. For example, the control unit 104 controls the humidifier 12 so that the humidity in room 10 approaches the target humidity acquired in step S22. For example, the control unit 104 controls the lighting fixture 13 so that the illuminance in room 10 approaches the target illuminance acquired in step S22.

[0053] <Effects of the Embodiment> In the embodiment described above, when the time-series changes of the measured values ​​measured by the environmental sensor 20A over a predetermined period are input, an environmental model 105 is constructed that outputs a target value that does not cause stress to the user 200. The control device 100 then inputs the time-series changes of the measured values ​​measured by the environmental sensor 20A over a predetermined period into the environmental model 105 to obtain the target value. The control device 100 controls the environmental equipment 20 so that the measured values ​​measured by the environmental sensor 20A approach the target value. Therefore, according to this embodiment, the environment inside the room 10 can be made an indoor environment in which the stress experienced by the user 200 is suppressed as much as possible.

[0054] For example, in a company office, the room temperature, humidity, and illuminance are likely to be controlled to maintain an environment suitable for work. However, when a user 200 works from home due to remote work, the indoor environment of the room where they work may not be suitable for work due to individual household circumstances. According to the environmental control system 1 of this embodiment, an environmental model 105 suitable for suppressing stress for user 200 is constructed based on the correspondence between the behavioral patterns that user 200 takes when they feel stressed and the measured values ​​measured by the environmental sensor 20A. Then, by controlling the environmental equipment 20 using this environmental model 105 and the measured values ​​measured by the environmental sensor 20A, an indoor environment can be realized that minimizes the stress experienced by user 200, even when working from home due to remote work.

[0055] In this embodiment, for example, the time-series change in room temperature measured by the temperature sensor 11A is input to the room temperature model 105A to obtain a target room temperature that does not cause stress to the user 200. The control device 100 controls the air conditioner 11 so that the room temperature measured by the temperature sensor 11A approaches the target room temperature. Therefore, according to this embodiment, it is possible to maintain a room temperature that minimizes the stress experienced by the user 200.

[0056] In this embodiment, for example, the time-series change in humidity measured by the humidity sensor 12A is input to the humidity model 105B to obtain a target humidity value that does not cause stress to the user 200. The control device 100 controls the humidifier 12 so that the humidity measured by the humidity sensor 12A approaches the target humidity value. Therefore, according to this embodiment, it is possible to maintain a humidity level that minimizes the stress experienced by the user 200.

[0057] In this embodiment, for example, the time-series change in illuminance measured by the illuminance sensor 13A is input to the illuminance model 105C to obtain a target illuminance value that does not cause stress to the user 200. The control device 100 controls the lighting fixture 13 so that the illuminance measured by the illuminance sensor 13A approaches the target illuminance value. Therefore, according to this embodiment, it is possible to maintain an illuminance that minimizes the stress experienced by the user 200.

[0058] <Variation> In the embodiments described above, eye rubbing and head scratching were cited as behavioral patterns indicating stress in user 200, but user 200's behavioral patterns indicating stress are not limited to these. Examples of behavioral patterns indicating stress in user 200 include the force with which the computer keyboard is pressed and the movement of the face. In this case, to acquire the force with which user 200 is pressed on the computer keyboard, for example, a microphone can be used instead of the camera 200A.

[0059] In the embodiments described above, the environmental equipment 20 included an air conditioner 11, a humidifier 12, and a lighting fixture 13, but the environmental equipment 20 is not limited to these. Examples of 0 include curtains with variable sound insulation properties and a pressure regulator that adjusts the air pressure inside room 10.

[0060] A curtain with variable sound insulation suppresses the intrusion of noise from the outside into room 10. An example of a curtain with variable sound insulation is one in which a motor is incorporated into the curtain rail, and the degree to which the curtain opens is controlled by driving the motor according to instructions from the control device 100. By controlling the degree to which the curtain opens, the sound insulation provided by the curtain can be varied. In this case, when using a curtain with variable sound insulation, a microphone can be used as the environmental sensor 20A, and an environmental model 105 can be constructed using the measured value indicating the loudness of sound generated in room 10 measured by the microphone and the behavioral pattern of the user 200. A curtain with variable sound insulation is an example of a "sound insulation part". The environmental model 105 constructed using the measured value indicating the loudness of sound generated in room 10 and the behavioral pattern of the user 200 is an example of a "noise model".

[0061] Another example of a pressure adjustment device is a compressor that draws outside air into room 10. By operating the compressor according to instructions from the control device 100, it is possible to draw outside air into room 10 to increase the pressure inside room 10, or to exhaust the air inside room 10 to decrease the pressure inside room 10. In this case, when a pressure adjustment device is used, a pressure sensor is adopted as the environmental sensor 20A, and an environmental model 105 should be constructed using the measured pressure value inside room 10 measured by the pressure sensor and the user 200's behavior pattern. The environmental model 105 constructed using the measured pressure value and the user 200's behavior pattern is an example of a "pressure model".

[0062] In this embodiment, the temperature sensor 11A is built into the air conditioner 11, but the temperature sensor 11A may be a separate piece of equipment from the air conditioner 11. In this embodiment, the humidity sensor 12A is built into the humidifier 12, but the humidity sensor 12A may be a separate piece of equipment from the humidifier 12. In this embodiment, the illuminance sensor 13A was a separate piece of equipment from the lighting fixture 13, but the illuminance sensor 13A may be built into the lighting fixture 13.

[0063] Furthermore, although the environmental model 105 was stored in the storage device 112 of the control device 100 in this embodiment, the storage device in which the environmental model 105 is stored is not limited to the storage device 112. The environmental model 105 may be stored in a storage device outside the control device 100, as long as it is accessible from the control device 100.
