[0038] <Risk Determination Unit> The risk determination unit 31 is configured to determine the disease risk of people in the building 10 based on the temperature.

[0039] [Disease risk assessment when a person moves to the first room] The risk assessment unit 31 is configured to assess the 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 and moves from that room to the first room 11, the risk assessment unit 31 assesses the disease risk of the person due to the temperature difference between the rooms.

[0040] When determining the disease risk related to heat shock, if the temperature of the first room 11 satisfies condition (A1) or (A2), the risk determination unit 31 determines that the disease risk of the person in the first room 11 is high. The first threshold and the second threshold can be set according to the season, temperature, age of the person, etc.

[0041] (A1) The temperature of the first room 11 is equal to or lower than a first threshold. (A2) The temperature of the first room 11 is lower than the temperature of the room where people are currently present by a second threshold or more. As an example, when determining the disease risk related to heat shock, if the temperature of the first room 11 meets condition (B1) or (B2), the risk determination unit 31 determines that the disease risk of people in the first room 11 is high.

[0042] (B1) The temperature of the first room 11 is 15°C or lower. (B2) The temperature of the first room 11 is 10°C or lower than the temperature of the location where the person is currently located. When determining the disease risk related to high blood pressure caused by high temperature, if the temperature of the first room 11 meets condition (C1) or (C2), the risk determination unit 31 determines that the person in the first room 11 has a high disease risk. 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, the person's age, etc.

[0043] (C1) The temperature of the first room 11 is equal to or lower than the third threshold. (C2) The temperature of the first room 11 is equal to or lower than the temperature of the room where people are currently present by equal to or higher than the fourth threshold. 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 satisfies condition (D1) or (D2), the risk determination unit 31 determines that the disease risk of people in the first room 11 is high.

[0044] (D1) The temperature of the first room 11 is 25°C or lower. (D2) The temperature of the first room 11 is 10°C lower than the temperature of the location where the person is currently present. [Disease Risk Assessment When a Person is Moving] The risk assessment unit 31 determines the route R from the second room 12 where the person is currently present to the first room 11. The risk assessment unit 31 identifies the second room 12 where the 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 assessment unit 31 identifies the 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 , the route R is illustrated as going from the private room 12b through the corridor 13 and the changing room 12a to the first room 11. The route R from a specific second room 12 to the first room 11 may be stored in advance in the control device 30. The risk determination unit 31 may be configured to derive the shortest route from the second room 12 where a person is currently present to the first room 11 as the route R.

[0045] 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.

[0046] [Disease risk assessment when a person is in the first room] When a person is in the first room 11, the risk assessment unit 31 assesses the disease risk of the person in the first room 11. Specifically, the risk assessment unit 31 assesses the disease risk of the person based on the temperature of the first room 11 in which the person is present.

[0047] When determining the disease risk related to heatstroke, if the temperature of the first room 11 is equal to or higher than a 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.

[0048] As an example, when determining the disease risk related to heatstroke, the risk determination unit 31 determines that the disease risk of people in the first room 11 is high if the temperature in the first room 11 is 28°C or higher.

[0049] 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.

[0050] The risk determination unit 31 is configured to determine the disease risk of a 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 for each condition, for example, according to the person's heart rate. 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.

[0051] <Risk Notification Unit> The risk notification unit 33 is configured to communicate with the user terminal 40.

The disease risk of a 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.

[0052] 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. When the disease risk of people in the first room 11 is high, the risk notification unit 33 may be configured to notify the user that the disease risk is high.

In the example of Figure 5, heart rate is stored as the current state. The room identification information is the identification number of the room in which a person is currently present. In the example of Figure 5, people who are not present in the building 10 are displayed as absent.

[0056] <Device Control Unit> 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. The device control unit 32 is configured to switch the operation state of the device 14 between an operating state and a stopped state when the risk determination unit 31 determines that the disease risk of the person in the first room 11 is high. The operating state is a state in which the device 14 is operating. The stopped state is a state in which the operation of the device 14 is stopped.

[0057] 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 people in the first room 11 is high. By setting the operating state of the air conditioning equipment 14a to an operating state, the equipment control unit 32 controls the equipment 14 so as to reduce the disease risk of people in the first room 11.

[0058] 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 building element 15. When the risk determination unit 31 determines that the disease risk of the person in the first room 11 is high and the state of the specific building element 15 is detected to be in a predetermined state, the equipment control unit 32 switches the operating state of the equipment 14.

[0059] In this embodiment, the predetermined state of the specific architectural element 15 includes the closed state of the opening / closing body 15a. The equipment control unit 32 is configured to change the operating state of the air conditioning equipment 14a to the operating state when the risk assessment unit 31 determines that the disease risk of the person in the first room 11 is high and the opening / closing body sensor 22a detects that the opening / closing body 15a is in the closed state. The equipment control unit 32 is configured to change the operating state of the air conditioning equipment 14a to the stopped state when the risk assessment unit 31 determines that the disease risk of the person in the first room 11 is high and the opening / closing body sensor 22a detects that the opening / closing body 15a is in the open state.

[0060] <User Terminal> 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. The user terminal 40 stores an application for linking with the control system 20. When the application is executed, 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.

[0061] As shown in FIGS. 1, 2, and 6, the display unit 41 displays, for example, a floor plan of the building 10. If it is determined that two or more of the multiple second rooms 12 are occupied by people, the user can select one of the rooms from the floor plan of the building 10 displayed on the display unit 41, for example, by tapping on one of the rooms. The risk notification unit 33 displays the route R determined by the risk assessment 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 registered in the person information who will move to the first room 11. The information displayed on the display unit 41 may be shared with multiple users. For example, the person information of the person moving to the first room 11 is shared with family members who are users. This allows family members to understand the disease risks that may arise from the elderly person's behavior.

[0062] 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. 6, locations on the route R with a high disease risk are displayed in a dark color. The disease risk may be displayed using an icon or a numerical value.

[0063] 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 will move to the first room 11, such as when the person moves to a predetermined room. An example of the setting of the first room 11 is when the first room 11 is the bathroom 11a, and the user sets the water heater in the bathroom 11a to start filling the water with hot water.

[0064] In step S11, the device control unit 32 determines whether or not the first room 11 has been set. The first room 11 is set, 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.

[0065] In step S12, the device control unit 32 determines whether 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. 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 processing.

[0066] In step S13, the device control unit 32 determines whether the operation state of the device 14 is stopped. 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 stopped, the device control unit 32 proceeds to step S14. If the operation state of the device 14 is not stopped, the device control unit 32 ends the process.

[0067] In step S14, the equipment control unit 32 determines whether the specific architectural element 15 of the first room 11 is in a predetermined state. For example, the equipment control unit 32 determines that the specific architectural element 15 is in a predetermined state when the specific architectural element 15, such as an opening / closing body or a curtain, is in a closed state. If the specific architectural element 15 of the first room 11 is in a predetermined state, the equipment control unit 32 proceeds to step S15. If 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 active state and then ends the processing.

[0068] Next, a second process related to the control of the device 14 by the device control unit 32 will be described. In 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 a person in the first room 11 is high, the operating state of the device 14 is automatically switched to an active state.

[0069] According to the second process, when there is a high risk of illness for people in the first room 11, 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.

[0070] <Operation of the embodiment> A first operation of the present embodiment will be described. The control system 20 of the present embodiment controls the devices 14 so as to reduce the risk of heat shock-related illnesses in people in the first room 11, for example. A hot water supply system is provided in the bathroom 11a. The hot water supply system is configured so that a 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, a user's operation to start the hot water supply operation.

[0071] 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 from the detection information of 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.

[0072] When the risk determination unit 31 determines that there is a high risk of heat shock-related illness for people in the bathroom 11a, the equipment control unit 32 switches the operating state of the air conditioning equipment 14a to an operating 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 people use the bathroom 11a, the risk of heat shock-related illness for people in the bathroom 11a is reduced.

[0073] A second operation of this embodiment will now be described. If the bathroom 11a has an opening / closing device 15a, the equipment control unit 32 maintains the operation state of the air conditioning device 14a in a stopped state when the opening / closing device 15a in the first room 11 is open, even if the risk assessment unit 31 determines that there is a high risk of heat shock-related illness in the bathroom 11a. This prevents the air conditioning device 14a from operating when there is no benefit to operating it, thereby saving energy. The risk notification unit 33 notifies the user that the opening / closing device 15a in the bathroom 11a is open. In this way, the control system 20 is configured so that the operation state of the air conditioning device 14a does not become active when the opening / closing device 15a is open. Because the air conditioning device 14a does not operate when the opening / closing device 15a is open, an increase in power consumption can be suppressed.

[0074] <Effects of the Embodiment> The effects of the present 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 the 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 the specific architectural element 15. The specific architectural element 15 is an architectural element for at least one of ventilation, insulation, lighting, and shading.

[0075] 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 the device 14 can be controlled more efficiently.

[0076] (2) The equipment control unit 32 is configured to change 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 and the opening / closing body sensor 22a detects that the opening / closing body 15a is in the closed state. The equipment control unit 32 is configured to change the operating 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 opening / closing body sensor 22a detects that the opening / closing body 15a is in the open state.

[0077] According to this configuration, the air conditioning equipment 14a is prevented from operating when the opening / closing body 15a is open, so that an increase in power consumption of the air conditioning equipment 14a in the first room 11 can be suppressed.

[0078] (3) The control system 20 further includes a route temperature sensor 23. The risk determination unit 31 is configured to determine the disease risk of people on the route R based on the temperature detected by the route temperature sensor 23. The control device 30 includes a risk notification unit 33. The risk notification unit 33 is configured to notify the user of the disease risk of people on the route R.

[0079] This configuration allows the user to grasp the disease risk along the route R to the first room 11. (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 are people 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. The risk determination unit 31 identifies the route R from the selected second room 12 to the first room 11 based on the information acquired by the location selection unit 35.

[0080] According to this configuration, the second room 12 can be suitably determined from the detection results of the human presence sensor 24, and the risk determination unit 31 can suitably determine the route R from the second room 12 to the first room 11.

[0081] (5) The control system 20 further includes a heart rate sensor 25 configured to detect a heart rate of the person. The risk determination unit 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.

[0082] With this configuration, the disease risk can be determined based on the heart rate in addition to the temperature of the first room 11, allowing the risk determination unit 31 to determine the disease risk more accurately. (6) The control system 20 includes a temperature sensor 21, a state 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 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. 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 specific architectural element 15 is an architectural element for at least one of ventilation, insulation, lighting, and shading.

[0083] 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 the control system 20 can control the device 14 more efficiently.

[0084] <Modifications> The above-described embodiments are examples of forms that the building 10 and the control system 20 can take, and are not intended to limit the forms. The building 10 and the control system 20 can take forms that are different from those exemplified in the above-described embodiments. Examples of such forms include forms in which part of the configuration of the embodiment is replaced, modified, or omitted, or forms in which a new configuration is added to the embodiment. Modifications of the embodiments are shown below.

[0085] <First Modification> The first room 11 may not be the bathroom 11a, but may be set as a room where a person is currently present and where a person would be at a high risk of disease if they were to move therefrom. The risk notification unit 33 may notify the user that a room where a person is currently present and where a person would be at a high risk of disease if they were to 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 is at a high risk of disease by the risk notification unit 33. The equipment control unit 32 is configured to switch the operation state of the air conditioning equipment 14a in the first room 11 to an operating state so as to reduce the risk of disease for people in the first room 11 in this modification.

[0086] If the first room 11 has an opening / closing device 15a, when the equipment control unit 32 detects that the opening / closing device 15a of the first room 11 is in the closed state, it switches the operation state of the air conditioning equipment 14a to the running state based on the user's operation input to the user terminal 40. When the disease risk related to heat shock in people in the first room 11 is reduced, the risk notification unit 33 notifies the user that the disease risk has been reduced.

[0087] When the equipment control unit 32 detects that the opening / closing device 15a of the first room 11 is in the open state, it keeps the operation state of the air conditioning equipment 14a in the stopped state regardless of the user's operation input to the user terminal 40. The risk notification unit 33 notifies the user that the opening / closing device 15a of the first room 11 is in the open state. With this configuration, the air conditioning equipment 14a does not operate when the opening / closing device 15a is open, so an increase in power consumption can be suppressed.

[0088] <Second Modification> The risk determination unit 31 may be configured to determine the disease risk related to heatstroke based on the person's heart rate. The risk determination unit 31 determines the disease risk related to heatstroke 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 related to heatstroke is high, the risk notification unit 33 notifies the user that the disease risk related to heatstroke is high. The heart rate sensor 25 detects the person's heart rate over one minute.

[0089] The risk determination unit 31 determines that the risk of heatstroke is high when, for example, the person's heart rate satisfies condition (E1) or (E2): (E1) The heart rate per minute (X) satisfies formula (A).

[0090] Formula (A): 185 - 0.65 x Y < X (E2) A 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.

[0091] Other Modifications The device 14 may be a heating device or a ventilation fan. The ventilation fan of this modification changes the temperature of the first room 11 by taking in outside air into the first room 11.

[0092] The specific architectural element 15 may be a curtain that blocks light from entering the bathroom 11a. When the curtain is open, sunlight enters, tending to raise the temperature of the first room 11. In this modification, the equipment control unit 32 operates the air conditioning unit 14a to lower the temperature of the bathroom 11a in order to reduce the risk of heatstroke-related illness in the bathroom 11a. Even if the risk assessment unit 31 determines that the risk of heatstroke-related illness in the bathroom 11a is high, the equipment control unit 32 maintains the operation of the air conditioning unit 14a in a stopped state if the curtain is open. This allows for energy conservation when operating the air conditioning unit 14a is ineffective. Note that the control system 20 may be configured to change settings to control the air conditioning unit 14a so that it switches on operation regardless of the state of the curtain when the risk of illness is high.

[0093] The human presence sensor 24 may be a carbon dioxide sensor. When a person is present in the first room 11, the carbon dioxide concentration will be higher than when no person is present. In this modified example, the risk determination unit 31 determines that a person is present in a location where the carbon dioxide concentration detected by the carbon dioxide sensor is equal to or higher than a predetermined threshold.

[0094] The human presence sensor 24 may include, for example, a camera. The risk assessment unit 31 may be configured to be able to determine, from the video captured by the camera, where a person is located in the building 10. When the building 10 is used by multiple people, the risk assessment unit 31 may determine, from the video captured by the camera, where each of the multiple people is located in the building 10.

[0095] An opening / closing device that controls the state of the specific architectural element 15 may be provided in the first room 11. For example, the opening / closing device is configured to switch the open / close state of the opening / closing body 15a. The opening / closing device may be controlled by the equipment control unit 32. When the risk determination unit 31 determines that there is a high risk of heat shock-related illness in people in the bathroom 11a, the equipment control unit 32 may switch the state of the opening / closing body 15a to the closed state using the opening / closing device if it detects that the opening / closing body 15a in the first room 11 is in the open state.

[0096] The path 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 path R. 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 the path R from the user's location input to the user terminal 40 to the first room 11.

[0097] The heart rate sensor 25 may be omitted from the control system 20. Control by the control system 20 may be performed by a control program. The control program is a program for controlling the equipment 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 a 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 architectural 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 equipment 14 based on the disease risk of the person in the first room 11 and the state of the specific architectural element 15. Steps corresponding to the control of the equipment 14 in the embodiment or modified example may be added to the control program as appropriate. According to this configuration, the equipment 14 is 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 based on the state of ventilation, insulation, lighting, or shading of the first room 11, the device 14 can be controlled more efficiently.
