When the user selects one of the two or more rooms, the location selection unit 35 identifies the room selected by the user as the room in which the person is currently present.

[0042] <Risk Assessment Department> The risk determination unit 31 is configured to determine the disease risk of people in the building 10 based on temperature.

[0043] [Disease risk assessment when people move to the first room] The risk determination unit 31 is configured to determine a disease risk of a person in the first room 11 based on the temperature of the first room 11 detected by the temperature sensor 21. Specifically, when a person is in a room other than the first room 11, the risk determination unit 31 determines a disease risk of the person due to a temperature difference between the rooms when the person moves from that room to the first room 11.

[0044] When determining the disease risk related to heat shock, if the temperature of the first room 11 satisfies the condition (A1) or (A2), the risk determination unit 31 determines that the risk of disease of the person in the first room 11 is high. The first and second thresholds can be set according to the season, temperature, age of the person, etc. (A1) The temperature of the first room 11 is equal to or lower than the first threshold value. (A2) The temperature of the first room 11 is lower than the temperature of the room in which someone is currently present by the second threshold value or more.

[0045] As an example, in determining the disease risk related to heat shock, if the temperature of first room 11 meets condition (B1) or (B2), risk determination unit 31 determines that the risk of disease of people in first room 11 is high. (B1) The temperature of the first chamber 11 is 15°C or lower. (B2) The temperature of the first room 11 is more than 10°C lower than the temperature of the location where people are currently present.

[0046] When determining the disease risk related to high blood pressure caused by high temperature, if the temperature of the first room 11 satisfies the condition (C1) or (C2), the risk determination unit 31 determines that the risk of disease of the person in the first room 11 is high. High blood pressure caused by high temperature is an example of a disease that occurs when moving to a room that is cooler than the current room. The third and fourth thresholds can be set according to the season, temperature, age of the person, etc. (C1) The temperature of the first room 11 is equal to or lower than the third threshold value. (C2) The temperature of the first room 11 is lower than the temperature of the room in which someone is currently present by the fourth threshold value or more.

[0047] As an example, when determining the disease risk related to high blood pressure caused by high temperature, if the temperature of the first room 11 meets condition (D1) or (D2), the risk determination unit 31 determines that the disease risk of people in the first room 11 is high. (D1) The temperature of the first chamber 11 is 25° C. or lower. (D2) The temperature of the first room 11 is 10°C lower than the temperature where people are currently located.

[0048] [Disease risk assessment when people are moving] The risk determination unit 31 determines a route R from the second room 12 in which a person is currently present to the first room 11. The risk determination unit 31 identifies the second room 12 in which a person is currently present based on the determination of the location determination unit 34. When the location determination unit 34 determines that there are people in two or more of the multiple second rooms 12, the risk determination unit 31 identifies a route R from the selected second room 12 to the first room 11 based on information acquired by the location selection unit 35. In the example of FIG. 1, a route R from the private room 12b to the first room 11 after passing through the corridor 13 and the dressing room 12a is illustrated. The route R from a predetermined second room 12 to the first room 11 may be stored in the control device 30 in advance. The risk determination unit 31 may be configured to derive the shortest route from the second room 12 in which a person is currently present to the first room 11 as the route R.

[0049] The risk determination unit 31 is configured to determine the disease risk of people on the route R based on the temperature on the route R detected by the route temperature sensor 23. The risk determination unit 31 determines the disease risk of people on the route R under the same conditions as those for determining the disease risk of people in the first room 11.

[0050] [Disease risk assessment when a person is in the first room] When a person is present in the first room 11, the risk determination unit 31 determines the disease risk of the person in the first room 11. Specifically, the risk determination unit 31 determines the disease risk of the person due to the temperature of the first room 11 in which the person is present.

[0051] When determining the disease risk related to heat stroke, if the temperature of the first room 11 is equal to or higher than the fifth threshold, the risk determination unit 31 determines that the disease risk of the person in the first room 11 is high. The fifth threshold can be set according to the season, temperature, age of the person, etc.

[0052] As an example, in determining the disease risk related to heat stroke, the risk determining unit 31 determines that the disease risk of people in the first room 11 is high if the temperature of the first room 11 is 28° C. or higher.

[0053] The risk determination unit 31 may be configured to determine the disease risk of a person in the first room 11 based on the heart rate. The risk determination unit 31 determines that the disease risk is high when the heart rate is equal to or higher than a sixth threshold. The sixth threshold can be set according to the season, temperature, age of the person, etc.

[0054] The risk determination unit 31 is configured to determine the disease risk of the person in the first room 11 based on the heart rate in addition to the temperature of the first room 11. The risk determination unit 31 may change the first to fifth thresholds of each condition according to the person's heart rate, for example. For example, the risk determination unit 31 changes the first to fifth thresholds so that the higher the person's heart rate, the easier it is to determine the person's disease risk. The risk determination unit 31 may change the first to fifth thresholds so that the person's disease risk is easier to determine when the person's heart rate indicates a tendency toward arrhythmia.

[0055] <Risk Notification Department> The risk notification unit 33 is configured to communicate with the user terminal 40. The risk notification unit 33 transmits information regarding the floor plan of the building 10, the route R, the disease risk of each room in the building 10, etc. to the user terminal 40. The risk notification unit 33 is configured to notify the user of the disease risk of the person in the first room 11. The disease risk of the person in the first room 11 includes the disease risk when the person moves to the first room 11, the disease risk when the person is moving, and the disease risk when the person is in the first room 11.

[0056] The risk notification unit 33 notifies the user of the disease risk of people in the first room 11 in response to a request from the user input to the user terminal 40. For example, when a person moves to the first room 11, the risk notification unit 33 is configured to notify the user of the disease risk of people on the route R in response to a request from the user input to the user terminal 40. The risk notification unit 33 notifies the user of the disease risk of people via the user terminal 40. The risk notification unit 33 may be configured to notify the user that the disease risk is high when the disease risk of the person in the first room 11 is high.

[0060] <Device control section> The device control unit 32 is configured to control the device 14 so as to reduce the disease risk of the person in the first room 11 based on the disease risk of the person in the first room 11. When the risk determination unit 31 determines that the disease risk of the person in the first room 11 is high, the device control unit 32 is configured to switch the operation state of the device 14 between an operating state and a stopped state. The operating state is a state in which the device 14 operates. The stopped state is a state in which the device 14 stops operating.

[0061] The equipment control unit 32 of this embodiment is configured to set the operating state of the air conditioning equipment 14a to an operating state when the risk determination unit 31 determines that the disease risk of the person in the first room 11 is high. The equipment control unit 32 controls the equipment 14 so as to reduce the disease risk of the person in the first room 11 by setting the operating state of the air conditioning equipment 14a to an operating state.

[0062] The equipment control unit 32 is configured to control the equipment 14 based on the disease risk of the person in the first room 11 and the state of the specific architectural element 15. The equipment control unit 32 executes switching of the operation state of the equipment 14 when the risk determination unit 31 determines that the disease risk of the person in the first room 11 is high and detects that the state of the specific architectural element 15 is in a predetermined state.

[0063] The predetermined state of the specific building element 15 in this embodiment includes a closed state of the fitting 15a. The equipment control unit 32 is configured to set the operation state of the air conditioning equipment 14a to an operating state when the risk determination unit 31 determines that the disease risk of the person in the first room 11 is high and the fitting sensor 22a detects that the fitting 15a is in a closed state. The equipment control unit 32 is configured to set the operation state of the air conditioning equipment 14a to a stopped state when the risk determination unit 31 determines that the disease risk of the person in the first room 11 is high and the fitting sensor 22a detects that the fitting 15a is in an open state.

[0064] <User device> As shown in FIG. 2, the user terminal 40 is, for example, a mobile terminal used by a user. The user terminal 40 is configured to allow the user to control the control system 20 via the user terminal 40. The user terminal 40 has a display unit 41. The display unit 41 is, for example, a display. An application for linking with the control system 20 is stored in the user terminal 40. By executing the application, an interface for the user to control the control system 20 is displayed on the display unit 41. The display unit 41 is configured to display at least one of room information, device information, and person information.

[0065] As shown in FIG. 1, FIG. 2, and FIG. 6, the display unit 41 displays, for example, a floor plan of the building 10. When it is determined that there are people in two or more of the second rooms 12, the user can select one of the rooms from the floor plan of the building 10 displayed on the display unit 41 by, for example, tapping one of the rooms. The risk notification unit 33 displays the route R determined by the risk determination unit 31 on the floor plan of the building 10 displayed on the display unit 41. The display unit 41 may be configured to allow the user to select, for example, a person who moves to the first room 11 from among people registered in the person information. The information displayed on the display unit 41 may be shared with multiple users. For example, the person information of the person who moves to the first room 11 is shared with the family as a user. This allows the family to understand the disease risk that may occur due to the behavior of the elderly person.

[0066] The risk notification unit 33 displays the disease risk of each room determined by the risk determination unit 31 on the floor plan of the building 10 displayed on the display unit 41. For example, in the example of Fig. 7, locations on the route R with high disease risk are displayed in a dark color. The disease risk may be displayed by an icon or a numerical value.

[0067] Fig. 7 shows a first process of the process related to the control of the device 14 by the device control unit 32. The process shown in Fig. 7 is executed at predetermined time intervals. The first process is executed, for example, by setting the first room 11. The setting of the first room 11 is a setting indicating that a person moves to the first room 11, such as the person moving to a predetermined room. An example of the setting of the first room 11 is, when the first room 11 is the bathroom 11a, a setting by the user to start a hot water filling operation on the water heater of the bathroom 11a.

[0068] In step S11, the device control unit 32 determines whether or not the first room 11 has been set. The setting of the first room 11 is performed, for example, via the user terminal 40. If the first room 11 has been set, the device control unit 32 proceeds to step S12. If the first room 11 has not been set, the device control unit 32 ends the process.

[0069] In step S12, the device control unit 32 determines whether or not the disease risk of the person in the first room 11 is high. For example, in step S12, the device control unit 32 causes the risk determination unit 31 to determine the disease risk of the first room 11. For example, the device control unit 32 determines that the disease risk is high when the numerical value related to the disease risk determined by the risk determination unit 31 is equal to or greater than a threshold value. If the disease risk of the person in the first room 11 is high, the device control unit 32 proceeds to step S13. If the disease risk of the person in the first room 11 is not high, the device control unit 32 ends the process.

[0070] In step S13, the device control unit 32 determines whether the operation state of the device 14 is a stopped state. The device control unit 32 determines the operation state of the device 14, for example, based on the device information in the device information storage unit 37. If the operation state of the device 14 is a stopped state, the device control unit 32 proceeds to step S14. If the operation state of the device 14 is not a stopped state, the device control unit 32 ends the process.

[0071] In step S14, the equipment control unit 32 judges whether the specific architectural element 15 of the first room 11 is in a predetermined state. For example, when the specific architectural element 15 such as a fitting or a curtain is in a closed state, the equipment control unit 32 judges that the specific architectural element 15 is in a predetermined state. When the specific architectural element 15 of the first room 11 is in a predetermined state, the equipment control unit 32 proceeds to step S15. When the specific architectural element 15 of the first room 11 is not in a predetermined state, the equipment control unit 32 ends the processing. In step S15, the equipment control unit 32 switches the operating state of the equipment 14 to an operating state and then ends the processing.

[0072] Next, a second process of the process related to the control of the device 14 by the device control unit 32 will be described. In the case of the second process, step S11 is omitted from the first process shown in FIG. 7 above. The second process is executed at predetermined time intervals. The first room 11 in the second process includes, for example, at least one of the rooms that can be set as the first room 11. The first room 11 in the second process may include multiple rooms. In the second process, if the disease risk of the person in the first room 11 is high, the operating state of the device 14 is automatically switched to an active state.

[0073] According to the second process, when the disease risk of a person in the first room 11 is high, the environment of the first room 11 is automatically adjusted. In this process example, a room other than the bathroom 11a may be set as the first room 11.

[0074] <Operation of the embodiment> A first effect of this embodiment will be described. The control system 20 of this embodiment controls the appliances 14 so as to reduce, for example, the risk of illness related to heat shock in people in the first room 11. A hot water supply system is provided in the bathroom 11a. The hot water supply system is configured so that the user can remotely start a hot water supply operation by operating an app on the user terminal 40. The setting of the first room 11 in step S11 of the process in FIG. 7 corresponds to, for example, an operation by the user to start a hot water supply operation.

[0075] When the user operates the app on the user terminal 40 to cause the hot water supply equipment to start a hot water supply operation, the risk determination unit 31 determines the room in which a person is currently present, based on the detection information from the human presence sensor 24. The risk determination unit 31 determines a route R from the room in which a person is currently present to the first room 11. The risk determination unit 31 determines the disease risk of people in the first room 11 and on the route R. The risk notification unit 33 notifies the user via the user terminal 40 of the disease risk of people in the first room 11 and on the route R determined by the risk determination unit 31.

[0076] When the risk determination unit 31 determines that the risk of heat shock-related illness for people in the bathroom 11a is high, the equipment control unit 32 switches the operating state of the air conditioning equipment 14a to an active state. By operating the air conditioning equipment 14a to warm the temperature of the bathroom 11a, the risk of heat shock-related illness for people in the bathroom 11a can be reduced. When the temperature of the bathroom 11a increases, reducing the risk of heat shock-related illness for people in the bathroom 11a, the risk notification unit 33 notifies the user that the risk of illness has been reduced. When a person uses the bathroom 11a, the risk of heat shock-related illness for people in the bathroom 11a is reduced.

[0077] A second effect of this embodiment will be described. When the bathroom 11a has a fitting 15a, the equipment control unit 32 maintains the operation state of the air conditioner 14a in a stopped state when the fitting 15a in the first room 11 is open, even if the risk determination unit 31 determines that the risk of heat shock-related illness in the bathroom 11a is high. This allows energy conservation because the air conditioner 14a is not operated when there is no effect in operating it. The risk notification unit 33 notifies the user that the fitting 15a in the bathroom 11a is open. In this way, the control system 20 is configured such that the operation state of the air conditioner 14a is not in an operating state when the fitting 15a is open. Since the air conditioner 14a does not operate when the fitting 15a is open, an increase in power consumption can be suppressed.

[0078] <Effects of the embodiment> The effects of this embodiment will be described. (1) The building 10 has a control system 20. The control system 20 includes a temperature sensor 21, a status detection sensor 22, and a control device 30. The control device 30 has a risk assessment unit 31 and an equipment control unit 32. The risk assessment unit 31 is configured to assess a disease risk of a person in the first room 11 based on the temperature of the first room 11 detected by the temperature sensor 21. The equipment control unit 32 is configured to control the equipment 14 based on the disease risk of the person in the first room 11 and the status of a specific architectural element 15. The specific architectural element 15 is an architectural element for at least one of ventilation, insulation, daylighting, and shading.

[0079] According to this configuration, the device 14 can be controlled based on the disease risk in the first room 11 and the state of the specific architectural element 15. In the first room 11, the device 14 is controlled based on the state of ventilation, insulation, lighting, or shading of the first room 11, so that the device 14 can be controlled more efficiently.

[0080] (2) The equipment control unit 32 is configured to set the operation state of the air conditioning equipment 14a to an operating state when the risk determination unit 31 determines that the disease risk of the person in the first room 11 is high and the door sensor 22a detects that the door 15a is closed. The equipment control unit 32 is configured to set the operation state of the air conditioning equipment 14a to a stopped state when the risk determination unit 31 determines that the disease risk of the person in the first room 11 is high and the door sensor 22a detects that the door 15a is open.

[0081] According to this configuration, the air conditioner 14a is prevented from operating while the fitting 15a is open, so that an increase in power consumption of the air conditioner 14a in the first room 11 can be suppressed.

[0082] (3) The control system 20 further includes a route temperature sensor 23. The risk determination unit 31 is configured to determine a disease risk of people on the route R based on the temperature detected by the route temperature sensor 23. The control device 30 has a risk notification unit 33. The risk notification unit 33 is configured to notify a user of a disease risk of people on the route R.

[0083] According to this configuration, the user can grasp the disease risk on the route R to the first room 11.

[0084] (4) The control system 20 further includes a human presence sensor 24. The control device 30 further includes a location determination unit 34 and a location selection unit 35. When the location determination unit 34 determines that there is a person in two or more of the multiple second rooms 12, the location selection unit 35 presents the two or more rooms to the user so that the user can select one of them. Based on the information acquired by the location selection unit 35, the risk determination unit 31 identifies a route R from the selected second room 12 to the first room 11.

[0085] According to this configuration, the second room 12 can be suitably determined from the detection result of the human presence sensor 24, and therefore the risk determination unit 31 can suitably determine the route R from the second room 12 to the first room 11.

[0086] (5) The control system 20 further includes a heart rate sensor 25 configured to detect a heart rate of the person. The risk determiner 31 is configured to determine a disease risk of the person in the first room 11 based on the heart rate in addition to the temperature of the first room 11.

[0087] According to this configuration, since the disease risk can be determined based on the heart rate in addition to the temperature of the first room 11, the risk determining unit 31 can determine the disease risk more accurately.

[0088] (6) The control system 20 includes a temperature sensor 21, a condition detection sensor 22, and a control device 30. The control device 30 has a risk determination unit 31 and an equipment control unit 32. The risk determination unit 31 is configured to determine a disease risk of a person in the first room 11 based on the temperature of the first room 11 detected by the temperature sensor 21. The equipment control unit 32 is configured to control the equipment 14 based on the disease risk of the person in the first room 11 and the condition of the specific architectural element 15. The specific architectural element 15 is an architectural element for at least one of ventilation, insulation, daylighting, and shading.

[0089] According to this configuration, the device 14 can be controlled based on the disease risk in the first room 11 and the state of the specific architectural element 15. Since the device 14 is controlled in the first room 11 based on the state of ventilation, insulation, lighting, or shading of the first room 11, the control system 20 can control the device 14 more efficiently.

[0090] <Modification> The above-described embodiment is an example of the form that the building 10 and the control system 20 can take, and is not intended to limit the form. The building 10 and the control system 20 can take a form different from the form exemplified in the above-described embodiment. Examples of such a form include a form in which part of the configuration of the embodiment is replaced, changed, or omitted, or a form in which a new configuration is added to the embodiment. Modified examples of the embodiment are shown below.

[0091] <First Modification> The first room 11 may be set not to the bathroom 11a but to a room where a person is currently present and where a person has a high disease risk if they move therefrom. The risk notification unit 33 may notify the user of a room where a person is currently present and where a person has a high disease risk if they move therefrom as the first room 11. In this modification, the setting of the first room 11 in step S11 of the processing in FIG. 7 corresponds to, for example, the setting of a room where a person has a high disease risk by the risk notification unit 33. The equipment control unit 32 is configured to switch the operating state of the air conditioning equipment 14a in the first room 11 to an operating state so as to reduce the disease risk of people in the first room 11 in this modification.

[0092] If the first room 11 has a fitting 15a, when the equipment control unit 32 detects that the fitting 15a in the first room 11 is in a closed state, it switches the operation state of the air conditioning equipment 14a to an active state based on the user's operation input to the user terminal 40. When the disease risk related to heat shock of people in the first room 11 is reduced, the risk notification unit 33 notifies the user that the disease risk has been reduced.

[0093] When the equipment control unit 32 detects that the fitting 15a in the first room 11 is open, it maintains the operation state of the air conditioning equipment 14a in a stopped state regardless of the user's operation input to the user terminal 40. The risk notification unit 33 notifies the user that the fitting 15a in the first room 11 is open. With this configuration, the air conditioning equipment 14a does not operate when the fitting 15a is open, so that an increase in power consumption can be suppressed.

[0094] <Second Modification> The risk determination unit 31 may be configured to determine the disease risk of heat stroke based on the person's heart rate. The risk determination unit 31 determines the disease risk of heat stroke based on the person's heart rate detected by the heart rate sensor 25. When the risk determination unit 31 determines that the disease risk of heat stroke is high, the risk notification unit 33 notifies the user that the disease risk of heat stroke is high. The heart rate sensor 25 detects the person's heart rate in one minute.

[0095] For example, when the person's heart rate meets the condition (E1) or (E2), the risk determining unit 31 determines that the risk of illness related to heat stroke is high. (E1) The number of heart beats per minute (X) satisfies equation (A). Formula (A): 185-0.65×Y <X (E2) Heart rate (X) that satisfies formula (B) continues for 5 minutes. Formula (B): 180-Y <X In formulas (A) and (B), X is the heart rate and Y is the person's age.

[0096] <Other Modifications> The device 14 may be a heating device or a ventilator. The ventilator of this modification changes the temperature of the first room 11 by taking in outside air into the first room 11.

[0097] The specific architectural element 15 may be a curtain that blocks light from the bathroom 11a. When the curtain is open, sunlight enters, and the temperature of the first room 11 tends to rise. In this modified example, the device control unit 32 operates the air conditioner 14a to cool the temperature of the bathroom 11a in order to reduce the disease risk of heat stroke of the person in the bathroom 11a. Even if the risk determination unit 31 determines that the disease risk of heat stroke of the person in the bathroom 11a is high, the device control unit 32 maintains the operation state of the air conditioner 14a in a stopped state when the curtain is open. This makes it possible to save energy when there is no effect in operating the air conditioner 14a. Note that the air conditioner 14a may be controlled to switch to an operation state of the air conditioner 14a regardless of the state of the curtain when the disease risk is high, by changing the settings on the control system 20.

[0098] The human presence sensor 24 may be a carbon dioxide sensor. When there is a person in the first room 11, the carbon dioxide concentration is higher than when there is no person there. The risk determination unit 31 of this modified example determines that there is a person in a location where the carbon dioxide concentration detected by the carbon dioxide sensor is equal to or higher than a predetermined threshold value.

[0099] The human presence sensor 24 may include, for example, a camera. The risk determination unit 31 may be configured to be able to determine where a person is located in the building 10 from an image captured by the camera. When multiple people use the building 10, the risk determination unit 31 may determine where each of the multiple people is located in the building 10 from the image captured by the camera.

[0100] An opening and closing device that controls the state of the specific architectural element 15 may be provided in the first room 11. For example, the opening and closing device is configured to switch the open and closed state of the fitting 15a. The opening and closing device may be controlled by the equipment control unit 32. When the risk determination unit 31 determines that there is a high disease risk related to heat shock for people in the bathroom 11a, the equipment control unit 32 may switch the state of the fitting 15a to the closed state by the opening and closing device if it detects that the fitting 15a in the first room 11 is in the open state.

[0101] The route temperature sensor 23 may be omitted from the control system 20. In this modification, the risk determination unit 31 does not need to determine the disease risk of people on the route R.

[0102] The human presence sensor 24 may be omitted from the control system 20. In this modification, the user's location may be directly input to the user terminal 40. The risk determination unit 31 may determine a route R from the user's location input to the user terminal 40 to the first room 11.

[0103] The heart rate sensor 25 may be omitted from the control system 20.

[0104] The control by the control system 20 may be executed by a control program. The control program is a program for controlling the device 14 arranged in the first room 11 of the building 10. The control program includes a first step, a second step, and a third step. In the first step, the control program causes the computer to determine the disease risk of the person in the first room 11 based on the temperature of the first room 11 detected by the temperature sensor 21. In the second step, the control program causes the computer to determine the state of the specific building element 15 from the detection result of the state detection sensor 22. In the first step, the control program causes the computer to control the device 14 based on the disease risk of the person in the first room 11 and the state of the specific building element 15. A step corresponding to the control of the device 14 in the embodiment or the modified example may be appropriately added to the control program. According to this configuration, the device 14 is controlled based on the disease risk in the first room 11 and the state of the specific building element 15. Since the device 14 is controlled based on the state of ventilation, insulation, lighting, or shading of the first room 11, the device 14 can be controlled more efficiently.
