[0014] A comfort evaluation value calculation system, a control system, a comfort evaluation value calculation method, a control method, and a program according to an embodiment will be described with reference to the drawings.

[0015] (Embodiment) (1) Overview An overview of the comfort evaluation value calculation system 10 and the control system 100 according to the embodiment will be described with reference to FIG. 1.

[0016] The comfort evaluation value calculation system 10 according to the embodiment calculates the comfort level for a person in a target space SP1 where air conditioning control is performed. Further, the control system 100 controls the air conditioner 30 in the target space SP1 based on the calculated comfort level.

[0017] The target space SP1 is, for example, a space to be air-conditioned in a facility. The target space SP1 may be a closed space that is part or all of a facility, or may be an open space that is part of a facility. The facility is, for example, an event space such as an event hall, an exhibition hall, a live house, a dome stadium, or a pavilion.

[0018] An air conditioner 30 is installed in the target space SP1. Further, a temperature sensor 41, a humidity sensor 42, a microphone 44, and a camera 45 are installed in the target space SP1. Furthermore, a plurality of wearable sensors 43 (only one is illustrated in FIG. 1) are used in the target space SP1. Each of the plurality of wearable sensors 43 includes a sensor capable of acquiring information related to a person's behavior or activity state. The plurality of wearable sensors 43 are carried by or worn on the human body of one or more of the plurality of people in the target space SP1. The plurality of wearable sensors 43 are, for example, lent or distributed to the plurality of people in the target space SP1. The plurality of wearable sensors 43 may, for example, be personal belongings of the plurality of people in the target space SP1.

[0019] (2) Configuration As shown in FIG. 1, the control system 100 according to the embodiment includes a comfort evaluation value calculation system 10 and an air conditioning control unit 20. The comfort evaluation value calculation system 10 includes an environmental comfort level calculation unit 11, a congestion degree calculation unit 12, an attention degree calculation unit 13, and an evaluation value calculation unit 14.

[0020] (2.1) Comfort evaluation value calculation system The comfort evaluation value calculation system 10 is a system that calculates a comfort evaluation value K0, which is the degree of comfort for a person in the target space SP1 where air conditioning control is performed. Hereinafter, a situation where cooling or dehumidification is required as the air conditioning control will be specifically described. The comfort evaluation value K0 is a value of 0 or more and 3 or less, and it can be inferred that the larger the value, the more comfortably the person in the target space SP1 is spending time. The comfort evaluation value K0 is, for example, "Eekimo Value" (registered trademark).

[0021] (2.2) Environmental comfort level calculation unit The environmental comfort level calculation unit 11 calculates the environmental comfort level E00 based on the state of the target space SP1.

[0022] The environmental comfort level E00 is calculated using one of several first comfort levels E1 to E3 calculated from the physical state of the target space SP1, and two second comfort levels E4 to E6, each of which is 1 or more, calculated from the actions of people within the target space SP1. Each of the multiple first comfort levels E1 to E3 and each of the two second comfort levels E4 to E6 is normalized to a value between 0 and 1. The environmental comfort level E00 is calculated by a linear combination of one of the multiple first comfort levels E1 to E3 and two second comfort levels E4 to E6, and is a value normalized to the range between 0 and 1.

[0023] (2.2.1) First level of comfort Each of the multiple first comfort levels E1 to E3 is calculated from the physical state of the target space SP1. The physical state of the target space SP1 includes, for example, the temperature and humidity of the target space SP1. Each of the multiple first comfort levels E1 to E3 is a value that indicates the state of the target space SP1, or a value that indicates the comfort level of the target space SP1 based on the state of the target space SP1.

[0024] The environmental comfort level calculation unit 11 calculates a first comfort level E1 based, for example, on the predicted mean vote (PMV). The environmental comfort level calculation unit 11 calculates the first comfort level E1 by, for example, calculating the PMV value based on a formula specified in ISO 773:2005 and normalizing the PMV. The environmental comfort level calculation unit 11 calculates the PMV value by, for example, obtaining temperature from a temperature sensor 41, obtaining humidity from a humidity sensor 42, and estimating the activity level and clothing amount of a person based on images obtained from a camera 45.

[0025] The environmental comfort level calculation unit 11 calculates the first comfort level E1 by normalizing the PMV value. First, as shown in Figure 2, the environmental comfort level calculation unit 11 takes the value obtained by subtracting the absolute value of the PMV value from 3 as the primary conversion value e1. The PMV value is an integer value between -3 and 3, and a smaller absolute value indicates greater comfort. Therefore, the primary conversion value e1 is a value between 0 and 3, and a larger absolute value indicates greater comfort. Next, as shown in Figure 3, the environmental comfort level calculation unit 11 calculates the first comfort level E1, which has been normalized to a value between 0 and 1 by multiplying the primary conversion value e1 by 1 / 3.

[0026] Furthermore, the environmental comfort calculation unit 11 calculates the first comfort level E2 from the temperature and humidity, for example, based on a psychrometric chart. Figure 4 shows an overview of a psychrometric hx chart, where the horizontal axis represents the dry-bulb temperature and the vertical axis represents the absolute humidity. The dry-bulb temperature is the temperature of the target space SP1. Absolute humidity is a value that indicates the ratio of the amount of moisture to the amount of dry air when the air in the target space SP1 is separated into dry air (DA) and moisture. For example, an absolute humidity of 0.010 kg / kg (DA) refers to the humidity of a gas in which 0.010 kg of moisture is added to 1 kg of dry air, and is the humidity of a gas in which the amount of moisture per 1.010 kg of air is 0.010 kg. Relative humidity (which is also simply called "humidity" in this specification) is a value that indicates the ratio of water vapor pressure to saturated water vapor pressure at that temperature, so even if the relative humidity is the same, the higher the temperature, the greater the absolute humidity, and the lower the temperature, the smaller the absolute humidity. In Figure 4, lines L11, L12, and L13 correspond to temperatures of 28°C, 26.5°C, and 25°C, respectively. Also in Figure 4, lines L21, L22, and L23 correspond to relative humidity of 70%, 55%, and 40%, respectively.

[0027] The environmental comfort level calculation unit 11 obtains the temperature of the target space SP1 from the temperature sensor 41 and the humidity of the target space SP1 from the humidity sensor 42, and calculates the first comfort level E2 by determining which region in Figure 4 the combination of temperature and humidity occupies.

[0028] The environmental comfort level calculation unit 11 determines the comfort level e2 to be 1 if a point plotted as a combination of temperature and humidity in the target space SP1 is located within region AR1, 2 if it is located within region AR2, 3 if it is located within region AR3, 4 if it is located within region AR4, and 0 if it is not located within any of regions AR1 to AR4. Next, the environmental comfort level calculation unit 11 calculates the normalized first comfort level E2 by multiplying the comfort level e2, which is a value between 0 and 4, by 1 / 4. Specifically, the relationship between the region where a point plotted as a combination of temperature and humidity in the target space SP1 is located and the first comfort level E2 is as shown in the table below.

[0029] [Table 1]

[0030] Region AR1 is the region that satisfies the conditions of a temperature of 26.5°C or higher and less than 28°C, and a humidity of 55% or higher and less than 70%. In other words, region AR1 is the region between line L21, which indicates a humidity of 70%, and line L22, which indicates a humidity of 55%, and the region that overlaps with line L22, in the vertical axis direction. Furthermore, region AR1 is the region between line L11, which indicates a temperature of 28°C, and line L12, which indicates a temperature of 26.5°C, and the region that overlaps with line L12, in the horizontal axis direction.

[0031] Furthermore, region AR2 is the region that satisfies the conditions of a temperature of 26.5°C or higher but less than 28°C and a humidity of less than 55%. In other words, region AR2 is the region below line L22, which indicates a humidity of 55%, in the vertical axis direction. Moreover, region AR2 is the region between line L11, which indicates a temperature of 28°C, and line L12, which indicates a temperature of 26.5°C, and the region that overlaps with line L12, in the horizontal axis direction.

[0032] Furthermore, region AR3 is the region that satisfies the conditions of a temperature below 26.5°C and a humidity between 55% and 70%. In other words, region AR3 is the region between line L21, which indicates 70% humidity, and line L22, which indicates 55% humidity, and the region that overlaps with line L22, in the vertical axis direction. Moreover, region AR3 is the region to the left of line L12, which indicates a temperature of 26.5°C, in the horizontal axis direction.

[0033] Furthermore, region AR4 is the region that satisfies the conditions of a temperature below 26.5°C and a humidity below 55%. In other words, region AR4 is the region below line L22, which indicates a humidity of 55%, in the vertical axis direction. Moreover, region AR4 is the region to the left of line L12, which indicates a temperature of 26.5°C, in the horizontal axis direction.

[0034] Furthermore, if the temperature is 28°C or higher, and the humidity is 70% or higher, or both, the area does not fall into any of the above-mentioned regions AR1 to AR4, and therefore the second primary comfort level E2 becomes 0.

[0035] Furthermore, the environmental comfort level calculation unit 11 calculates the first comfort level E3 from, for example, the discomfort index e3. There is a relationship between the discomfort index e3, the temperature t1°C, and the humidity (relative humidity) m1% shown by the following formula.

[0036] e3=0.81×t1+0.01×m1×(0.99×t1-14.3)+46.3 The environmental comfort level calculation unit 11 obtains the temperature of the target space SP1 from the temperature sensor 41 and the humidity of the target space SP1 from the humidity sensor 42, and calculates the discomfort index e3. Next, the environmental comfort level calculation unit 11 normalizes the discomfort index e3 as follows and calculates the first comfort level E3. Specifically, the relationship between the discomfort index e3 and the first comfort level E3 is as follows.

[0037] [Table 2]

[0038] Figure 5 is a table showing the relationship between temperature, humidity, and the discomfort index e3. Note that in Figure 5, the values ​​of the discomfort index e3 have been rounded to the nearest integer. Therefore, for a value of 70, there is a mix of values ​​between 69.5 and 70, and values ​​between 70 and 70.5. Similarly, the same value of 70 can represent both a value with a corresponding first comfort level E3 of 1 and a value with a corresponding first comfort level E3 of 0.75. The same applies to values ​​where the discomfort index e3 is represented as 75, 80, and 85.

[0039] In Figure 5, if the area belongs to region R2, the first comfort level E3 is 1. Also, if the area belongs to region R3, the first comfort level E3 is 0.75. Also, if the area belongs to region R4, the first comfort level E3 is 0.5. Also, if the area belongs to region R5, the first comfort level E3 is 0.25. Also, if the area belongs to region R1 or R6, or is outside the range of Figure 5, the first comfort level E3 is 0.

[0040] (2.2.2) Second level of comfort Each of the secondary comfort levels E4 to E6, which is 1 or greater, is calculated from the actions of people within the target space SP1. The actions of people within the target space SP1 refer to actions taken by people within the target space SP1 that are caused by, for example, a low level of comfort in the target space SP1 or a high level of comfort in the target space SP1. Each of the secondary comfort levels E4 to E6, which is 1 or greater, is a value that indicates the level of comfort in the target space SP1, which can be inferred from the actions of people within the target space SP1.

[0041] The environmental comfort level calculation unit 11, for example, normalizes the data acquired from the wearable sensor 43 to calculate the second comfort level E4.

[0042] The wearable sensor 43 is, for example, a smartwatch or a smart ring, and is capable of measuring the heart rate per minute of a person wearing the wearable sensor 43. The environmental comfort level calculation unit 11 normalizes the heart rate per minute obtained from the wearable sensor 43 and calculates it as the second comfort level E4.

[0043] Furthermore, for example, the wearable sensor 43 is a fan capable of detecting the intensity of fanning (hereinafter referred to as a "smart fan"). The smart fan wearable sensor 43 includes, for example, an inertial sensor, a communication unit, and a power supply. The environmental comfort level calculation unit 11 obtains the intensity of fanning from the wearable sensor 43, normalizes it, and calculates the second comfort level E4.

[0044] Furthermore, the environmental comfort level calculation unit 11 calculates a second comfort level E5 based on, for example, the audio data acquired from the microphone 44. The environmental comfort level calculation unit 11 detects from the audio data whether or not there are any statements made by people regarding comfort, normalizes the frequency of statements, and calculates the second comfort level E5.

[0045] The environmental comfort level calculation unit 11 detects the frequency of statements indicating discomfort, such as "it's hot" or "it's cold," and sets the second comfort level E5 such that the value of the second comfort level E5 approaches 0 as the frequency of such statements increases, and approaches 1 as the frequency of such statements decreases. The environmental comfort level calculation unit 11 divides the frequency of statements indicating discomfort by a predetermined value and takes the value obtained by subtracting the division result from 1 as the second comfort level E5. The predetermined value is, for example, the maximum frequency of statements indicating discomfort so that the value of the second comfort level E5 does not become a negative number.

[0046] Furthermore, the environmental comfort level calculation unit 11 calculates a second comfort level E6 based on image data acquired from the camera 45. The environmental comfort level calculation unit 11 detects the presence or absence of human gestures related to comfort from the image data, normalizes the frequency of the gestures, and calculates the second comfort level E6.

[0047] The environmental comfort level calculation unit 11 detects actions taken by a person when the environment of the target space SP1 is not optimal, such as fanning oneself or taking off a jacket. The environmental comfort level calculation unit 11 sets the second comfort level E6 such that the more frequently a person takes an action when the environment of the target space SP1 is not optimal, the closer the value of the second comfort level E6 approaches 0, and the less frequently the action, the closer the value of the second comfort level E6 approaches 1. The environmental comfort level calculation unit 11 divides the number of people performing the action by a predetermined value and takes the value obtained by subtracting the division result from 1 as the second comfort level E6. The predetermined value is, for example, the maximum number of people in the target space SP1 so that the value of the second comfort level E6 does not become a negative number.

[0048] (2.2.3) Environmental comfort level The environmental comfort level calculation unit 11 calculates the environmental comfort level E00 using one of the multiple first comfort levels E1 to E3 and one or more second comfort levels E4 to E6. The environmental comfort level E00 is calculated, for example, by the following formula.

[0049] E00=a1×E01+a2×E4+a3×E5+a4×E6 Here, the first comfort level E01 is a single value selected from multiple first comfort levels E1 to E3. Also, the sum of the coefficients a1, a2, a3, and a4 is 1. That is, a1 + a2 + a3 + a4 is 1. As a result, the environmental comfort level E00 is a value between 0 and 1, inclusive.

[0050] Furthermore, the first comfort level E01 is equal to any one of the first comfort levels E1, E2, and E3. For example, if the environmental comfort level calculation unit 11 can calculate the first comfort level E1, it uses the first comfort level E1 as the first comfort level E01. Also, for example, if the environmental comfort level calculation unit 11 cannot calculate the first comfort level E1, it uses the first comfort level E2 as the first comfort level E01 if the target space SP1 is indoors. Also, for example, if the environmental comfort level calculation unit 11 cannot calculate the first comfort level E1, it uses the first comfort level E3 as the first comfort level E01 if the target space SP1 is outdoors.

[0051] In other words, if the environmental comfort level calculation unit 11 can calculate the first comfort level E1, it uses the first comfort level E1 as the first comfort level E01. If the first comfort level E1 cannot be calculated, the environmental comfort level calculation unit 11 uses the first comfort level E2 as the first comfort level E01 if the target space SP1 is indoors, and the first comfort level E3 as the first comfort level E01 if the target space SP1 is outdoors. This makes it possible for the environmental comfort level calculation unit 11 to use an evaluation value suitable for the spatial characteristics of the target space SP1 as the first comfort level E01.

[0052] Furthermore, since the environmental comfort level calculation unit 11 calculates the environmental comfort level E00 using one or more of the multiple second comfort levels E4 to E6, the value of a2 + a3 + a4 is greater than 0 and less than 1. Each of the coefficients a2, a3, and a4 is a value of 0 or greater and less than 1. At least one of the coefficients a2, a3, and a4 is greater than 0, and one or two of the coefficients a2, a3, and a4 may be 0. For example, the environmental comfort level calculation unit 11 may use all of the second comfort levels E4, E5, and E6 as second comfort levels of 1 or greater. Also, for example, the environmental comfort level calculation unit 11 may set coefficient a2 to 0 if there is no wearable sensor 43 in the target space SP1.

[0053] (2.3) Congestion level calculation unit The congestion level calculation unit 12 calculates the congestion level C00 of the target space SP1.

[0054] The congestion level calculation unit 12 calculates the congestion level C00 of the target space SP1 based on, for example, the congestion rate C1. The congestion rate C1 is the value obtained by dividing the number of people C01 in the target space SP1 by the capacity P1 of the target space SP1. In other words, the following equation holds true.

[0055] C1 = C01 / P1 Normalization is performed so that the more crowded the target space SP1 is, the closer the congestion level C00 is to 0, and the less crowded the target space SP1 is, the closer the congestion level C00 is to 1. Specifically, the relationship between the congestion rate C1 and the congestion level C00 is as follows:

[0056] [Table 3]

[0057] The congestion level calculation unit 12 calculates the congestion level C00 based on the graph in Figure 6, for example.

[0058] The congestion level calculation unit 12, for example, acquires an image of the target space SP1 from the camera 45, estimates the number of people C01 in the target space SP1 based on the image, and calculates the congestion rate C1. Alternatively, the congestion level calculation unit 12 may estimate the number of people C01 in the target space SP1 from an image of the target space SP1 and calculate the congestion rate C1. From the value of the congestion rate C1, the congestion level calculation unit 12 calculates the normalized congestion level C00 of the target space SP1.

[0059] Furthermore, the congestion level calculation unit 12 may calculate the congestion rate C2 by obtaining the number of people in the target space SP1 from, for example, entry / exit management information of the target space SP1 or the reservation status of events, instead of from images. For example, the congestion level calculation unit 12 obtains the number of people C02 reserved for events taking place in the target space SP1 from the facility server 60 (see Figure 1) that manages the target space SP1 via the network NT1. The congestion level calculation unit 12 calculates the congestion rate C2 obtained by dividing the number of people C02 reserved by the capacity P1 of the target space SP1. In other words, the following equation holds true.

[0060] C2 = C02 / P1 The congestion level calculation unit 12 calculates the normalized congestion level C00 from the congestion rate C2 in the same manner as the method described above for calculating the congestion level C00 by normalizing the congestion rate C1.

[0061] Furthermore, when calculating the congestion rate C1 or congestion rate C2, the congestion calculation unit 12 may use the value of the capacity P1 of the target space SP1 divided by a weighting coefficient, rather than the actual capacity.

[0062] (2.4) Attention level calculation unit The attention level calculation unit 13 calculates the attention level B00 for the target space SP1. The attention level B00 for the target space SP1 includes, for example, the degree of attention (attention) to the target space SP1 itself, and the degree of attention (attention) to the event currently taking place in the target space SP1. The degree of attention (attention) here refers to an indicator of how much interest a person has in the target space SP1 or the event, how much the person is enjoying themselves in the target space SP1 or the event, and how lively the atmosphere is. The attention level B00 is a normalized value between 0 and 1. The attention level B00 is calculated based on the first attention level B0 and the second attention levels B1, B2, B3, and B4, which are 1 or greater. The attention level B00 is a weighted average of the first attention level B0 and the second attention levels B1 to B4, which are 1 or greater.

[0063] (2.4.1) First choice The first level of attention, B0, represents the degree of attention given to the target space SP1 on the internet. For example, the first level of attention, B0, is the degree of attention given to the target space SP1 in an internet communication service. An internet communication service is, for example, a social networking service (SNS), and the first level of attention, B0, is, for example, the so-called "buzz level." The "buzz level" is the degree of attention given to the target space SP1, or an event currently taking place in the target space SP1, on an SNS.

[0064] The attention level calculation unit 13, for example, acquires information from an SNS server 50 that provides SNS services via the network NT1, evaluates the extent to which information containing keywords indicating the target space SP1 or events currently taking place in the target space SP1 exists on a 6-point scale from 0 to 5, and outputs the value divided by 5 for normalization as the first attention level (buzz level) B0. Note that the first attention level B0 is not limited to the buzz level as long as it is an indicator of the degree of attention to the target space SP1 on the SNS. Also, the communication service on the internet is not limited to SNS, but may be so-called social media.

[0065] (2.4.2) Second degree of attention The second attention level B1 to B4, which is 1 or higher, is based on the actions of a person in the target space SP1. Actions in the target space SP1 include, for example, sounds in the target space SP1, the posture of a person in the target space SP1, and the state of a person in the target space SP1. In this embodiment, the second attention level B1 to B4 is based on the sounds in the target space SP1, the posture of a person in the target space SP1, and the state of a person in the target space SP1, respectively.

[0066] The attention level calculation unit 13 calculates the second attention level B1 based on, for example, the cheers and applause generated in response to an event in the target space SP1. The attention level calculation unit 13 acquires sound from the microphone 44 and evaluates the sound pressure of the cheers and applause generated in response to the event on a scale of 101 from 0 to 100. The attention level calculation unit 13 normalizes the sum of the evaluated values ​​of the cheer sound pressure and the evaluated values ​​of the applause sound pressure, which is between 0 and 200, and outputs it as the second attention level B1. For example, the relationship between the sum of the evaluated values ​​and the second attention level B1 is as follows.

[0067] [Table 4]

[0068] The relationship between the sum of the evaluation values ​​and the second attention score B1 does not have to be as described above. The attention score calculation unit 13 may also calculate the second attention score B1 from the sum of the weighted sum of the evaluation values ​​of the sound pressure of cheers and the sound pressure of applause. Alternatively, the second attention score B1 may be calculated from either the sound pressure of cheers or the sound pressure of applause that occur in response to the event. For example, if the event is a classical concert, the occurrence of cheers is limited, while the sound pressure of clapping or applause increases in response to the excitement of the event, so the second attention score B1 may be calculated from the sound pressure of applause. Similarly, in an event where the occurrence of applause is limited and the sound pressure of cheers increases in response to the excitement of the event, the second attention score B1 may be calculated from the sound pressure of cheers.

[0069] Furthermore, the attention level calculation unit 13 calculates a second attention level B2 based on, for example, the content of the sound generated in the target space SP1. The attention level calculation unit 13 analyzes the sound acquired from the microphone 44 and calculates the frequency of keywords indicating the target space SP1 or an event currently taking place in the target space SP1. The attention level calculation unit 13 normalizes the difference frequency value obtained by subtracting the frequencies of three negative keywords from the frequencies of four positive keywords. Here, if the frequency of the three negative keywords is greater than or equal to the frequency of the four positive keywords, the attention level calculation unit 13 treats the difference frequency value as 0 instead of a negative value less than 0. The attention level calculation unit 13 outputs a value normalized to a keyword frequency of 0 or more and 1 or less as the second attention level B2.

[0070] Furthermore, the attention-grabbing calculation unit 13 calculates a second attention-grabbing score B3 based, for example, on the posture of a person in the target space SP1. The attention-grabbing calculation unit 13 acquires images captured from the camera 45 within the target space SP1 and evaluates the degree of the person's engagement based on their posture, arm position, arm movement, etc. The attention-grabbing calculation unit 13 normalizes the difference frequency value obtained by subtracting the frequencies of two negative actions from the frequencies of two positive actions. Here, if the frequency of the two negative actions is greater than or equal to the frequency of the two positive actions, the attention-grabbing calculation unit 13 treats the difference frequency value as 0 instead of a negative value less than 0. The attention-grabbing calculation unit 13 outputs a normalized value between 0 and 1 as the second attention-grabbing score B3.

[0071] Furthermore, the attention level calculation unit 13 calculates a second attention level B4 based on, for example, the state of a person in the target space SP1. The attention level calculation unit 13 calculates the second attention level B4 by normalizing information related to the state of a person indicating the degree of heat, obtained from the wearable sensor 43. The information related to the state of a person indicating the degree of heat is a value calculated by the wearable sensor 43, and is based on, for example, heart rate, steps taken, etc. The attention level calculation unit 13 outputs a value normalized from the information related to the state of a person indicating the degree of heat obtained from the wearable sensor 43 to between 0 and 1 as the second attention level B4.

[0072] The attention level calculation unit 13 calculates the attention level B00 from the first attention level B0 and the second attention level B1 to B4, which are 1 or more. The attention level B00 is calculated, for example, by the following formula.

[0073] B00=a5×B0+a6×B1+a7×B2+a8×B3+a9×B4 Here, the sum of coefficients a5, a6, a7, a8, and a9 is 1. That is, a5 + a6 + a7 + a8 + a9 is 1. Also, coefficient a5 is greater than 0 and less than 1. Furthermore, each of coefficients a6, a7, a8, and a9 is a value between 0 and 1, and at least one of coefficients a6, a7, a8, and a9 is greater than 0. In other words, the attention level B00 is calculated from the first attention level B0 and one or more of the four second attention levels B1 to B4.

[0074] Each of the coefficients a6, a7, a8, and a9 may, for example, have the same value. Also, for example, among the second attention scores B1 to B4 that are 1 or greater, the coefficient corresponding to the second attention score that has lower accuracy than the other second attention scores, or the second attention score that cannot be obtained, may be made smaller than the other coefficients. This makes it possible to improve the accuracy of the attention score B00. In this embodiment, the coefficients a6, a7, a8, and a9 are all values ​​greater than 0 and less than 1, and the attention score B00 is calculated using the first attention score B0 and all four second attention scores B1 to B4. Note that the attention score B00 may also be calculated using the first attention score B0 and some of the four second attention scores B1 to B4, and some of the values ​​of a6, a7, a8, and a9 may be 0.

[0075] (2.5) Evaluation Value Calculation Unit The evaluation value calculation unit 14 calculates a comfort evaluation value K0 based on the environmental comfort level E00, the congestion level C00, and the attention level B00. The comfort evaluation value K0 is calculated, for example, by the following formula.

[0076] K0 = a10 × E00 + a11 × C00 + a12 × B00 Here, the sum of the coefficients a10, a11, and a12 is 3. That is, a10 + a11 + a12 is 3. Also, each of the coefficients a10, a11, and a12 is a value greater than 0 and less than 3. For example, the coefficients a10, a11, and a12 are all 1.

[0077] The comfort evaluation value K0 may include environmental comfort E00, congestion C00, attention level B00, and one or more other parameters indicating comfort. Each of these one or more parameters is normalized to a value between 0 and 1, with higher values ​​indicating greater comfort. The comfort evaluation value K0 is represented by a linear combination of environmental comfort E00, congestion C00, attention level B00, and one or more other parameters. The range of the comfort evaluation value K0 depends on the number of parameters, including the one or more other parameters; if there is only one other parameter, the comfort evaluation value K0 will be between 0 and 4.

[0078] (2.6) Other components of the comfort evaluation value calculation system The comfort evaluation value calculation system 10 may include, for example, an image generation unit. The image generation unit generates an image 200 (see Figure 7) that shows, for example, the environmental comfort level E00 (indicated as "E" in Figure 7), the congestion level C00 (indicated as "C" in Figure 7), the attention level B00 (indicated as "Buzz level B" in Figure 7), and the comfort evaluation value K0 (indicated as "Good comfort value K" in Figure 7), and displays it on, for example, a smartphone.

[0079] Image 200 includes, for example, a space name 201, a graph 202, and an evaluation value list 203. Space name 201 displays the name of the target space SP1. Graph 202 is a radar chart showing the values ​​of environmental comfort E00, congestion C00, and attention level B00, and their balance. Evaluation value list 203 is a list showing, for example, the unnormalized value of the first comfort level used to calculate environmental comfort E00, the congestion rate used to calculate congestion C00, and the unnormalized value of the first attention level B0 used to calculate attention level B00.

[0080] The comfort evaluation value calculation system 10 includes, for example, a computer system. The computer system has, for example, a processor and memory. The computer system realizes the functions of the comfort evaluation value calculation system 10 by executing a program stored in memory using the processor. The comfort evaluation value calculation system 10 is implemented, for example, as a server device. However, the comfort evaluation value calculation system 10 does not need to be a single server device; the environmental comfort level calculation unit 11, the congestion level calculation unit 12, the attention level calculation unit 13, and the evaluation value calculation unit 14 may be implemented as different server devices. Furthermore, part or all of the comfort evaluation value calculation system 10 may be implemented by cloud computing. For example, the environmental comfort level calculation unit 11, the congestion level calculation unit 12, and the attention level calculation unit 13 may be implemented by different virtual computers.

[0081] (3) Control system The control system 100 is a system that controls the air conditioning system of the target space SP1 based on the comfort evaluation value K0. The control system 100 includes, for example, a comfort evaluation value calculation system 10 and an air conditioning control unit 20.

[0082] The air conditioning control unit 20 controls the air conditioning system (for example, the air conditioning device 30 shown in Figure 1) within the target space SP1. The air conditioning control unit 20 controls the air conditioning device 30 to reduce its power consumption, for example, based on the comfort evaluation value K0. More specifically, the air conditioning control unit 20 reduces the power consumption of the air conditioning device 30 within the range where the comfort evaluation value K0 is above a threshold.

[0083] The comfort rating K0 is a value represented by a linear combination of environmental comfort E00, congestion C00, and attention level B00. Therefore, for example, the comfort rating K0 may be similar when environmental comfort E00, congestion C00, and attention level B00 are all roughly equal, and when attention level B00 is greater than both environmental comfort E00 and congestion C00. In other words, if one of these three values ​​is high, it is possible to achieve a similar comfort rating K0 even if the other two are low.

[0084] The air conditioning control unit 20, for example, raises the target temperature of the air conditioning unit 30 and reduces the power consumption of the air conditioning unit 30 if the comfort evaluation value K0 is greater than a threshold and the difference between the comfort evaluation value K0 and the threshold is large. Specifically, for example, if the difference between the comfort evaluation value K0 and the threshold is greater than or equal to a predetermined value, the air conditioning control unit 20 sets the target temperature of the air conditioning unit 30 to a second temperature (26.6°C), which is 0.1 degrees higher than the first temperature (26.5°C). If the comfort evaluation value K0 and the threshold are less than a predetermined value, the air conditioning control unit 20 sets the target temperature of the air conditioning unit 30 to the first temperature (26°C). Through the above control, it is possible to achieve both comfort in the target space SP1 and energy saving of the air conditioning system.

[0085] The control system 100 includes, for example, a computer system. The computer system has, for example, a processor and memory. The computer system realizes the functions of the control system 100 by executing programs stored in memory using the processor. The control system 100 is implemented, for example, as a server device. In the control system 100, the comfort evaluation value calculation system 10 and the air conditioning control unit 20 may be implemented on different server devices. Furthermore, part or all of the comfort evaluation value calculation system 10 may be implemented using cloud computing.

[0086] (4) Operation The operation of the comfort evaluation value calculation system 10 and the control system 100 according to the embodiment will be explained using Figure 8.

[0087] First, the environmental comfort calculation unit 11 of the comfort evaluation value calculation system 10 calculates the environmental comfort level E00 (step ST11). The environmental comfort calculation unit 11 calculates the environmental comfort level E00 using, for example, the temperature and humidity, which are the physical conditions of the target space SP1, and information from the wearable sensor 43, microphone 44, and camera 45.

[0088] Next, the congestion level calculation unit 12 of the comfort evaluation value calculation system 10 calculates the congestion level C00 (step ST12). The congestion level calculation unit 12 calculates the congestion level C00 based, for example, on the number of people in the target space SP1.

[0089] Next, the attention level calculation unit 13 of the comfort evaluation value calculation system 10 calculates the attention level B00 (step ST13). The attention level calculation unit 13 calculates the attention level B00 based on, for example, a first attention level B0, which is the level of attention to the target space SP1 on social networking services (SNS) on the internet, and second attention levels B1 to B4, which are based on sounds in the target space SP1, the posture of people in the target space SP1, or the facial expressions of people in the target space SP1.

[0090] Next, the evaluation value calculation unit 14 of the comfort evaluation value calculation system 10 calculates the comfort evaluation value K0 (step ST14). The evaluation value calculation unit 14 calculates the comfort evaluation value K0 based on the environmental comfort level E00, congestion level C00, and attention level B00 calculated in each of steps ST11 to ST13.

[0091] This completes one cycle of operation for the comfort evaluation value calculation system 10. As described later, the comfort evaluation value calculation system 10 executes steps ST11 to ST14 at predetermined intervals to calculate the comfort evaluation value K0.

[0092] Next, the air conditioning control unit 20 of the control system 100 performs air conditioning control (step ST21). The air conditioning control unit 20 reduces the power consumption of the air conditioning unit 30 within a range where the comfort evaluation value K0 does not fall below a threshold. For example, if the comfort evaluation value K0 is a certain amount greater than the threshold, the air conditioning control unit 20 controls the air conditioning unit 30 to raise the target temperature by 0.1 degrees.

[0093] This completes one cycle of operation for the control system 100. The control system 100 executes steps ST11 to ST14 and ST21 at predetermined intervals. As a result, the comfort evaluation value calculation system 10 works in conjunction with the control system 100 to execute steps ST11 to ST14 at predetermined intervals.

[0094] (5) Effects The comfort evaluation value calculation system 10 according to the embodiment comprises an environmental comfort level calculation unit 11, a congestion level calculation unit 12, a focus level calculation unit 13, and an evaluation value calculation unit 14.

The congestion level calculation unit 12 calculates the congestion level C00 of the target space SP1. The focus level calculation unit 13 calculates the focus level B00 for the target space SP1. The evaluation value calculation unit 14 calculates the comfort evaluation value K0 based on the environmental comfort level E00, the congestion level C00, and the focus level B00. As a result, the comfort evaluation value calculation system 10 according to the embodiment can more accurately evaluate the comfort evaluation value K0, which indicates the level of comfort of people in the target space SP1. Therefore, air conditioning control that maximizes the comfort of people in the target space SP1 can be implemented.

[0095] Furthermore, in the comfort evaluation value calculation system 10 according to the embodiment, the environmental comfort level calculation unit 11 calculates the environmental comfort level E00 using the physical state of the target space SP1 and the behavior of people in the target space SP1.

As a result, the comfort evaluation value calculation system 10 according to the embodiment can calculate the attention level B00 more accurately based on both, for example, the first attention level B0 on ​​social networking services (SNS) on the internet and the second attention levels B2 to B4, which indicate the degree of engagement of people in the target space SP1.

As a result, the control system 100 according to this embodiment can more accurately evaluate the level of comfort of people in the target space SP1. Therefore, it becomes possible to save energy without compromising the comfort of people in the target space SP1, thus achieving both comfort and energy saving.

[0099] Furthermore, in the control system 100 according to the embodiment, if the comfort evaluation value K0 is above a predetermined value, the air conditioning control unit 20 sets the target temperature of the air conditioning unit 30 to a second temperature higher than the first temperature. If the comfort evaluation value K0 is below a predetermined value, the air conditioning control unit 20 returns the target temperature of the air conditioning unit 30 to the first temperature. As a result, the control system 100 according to the embodiment makes it possible to reduce the power consumption of the air conditioning unit 30 to a extent that does not impair the comfort of people in the target space SP1.

[0100] The comfort evaluation value calculation method according to the embodiment includes an environmental comfort level calculation step ST11, a congestion level calculation step ST12, an attention level calculation step ST13, and an evaluation value calculation step ST14.

The program according to the embodiment causes one or more processors to execute the comfort evaluation value calculation method according to the embodiment.

[0101] As a result, the comfort evaluation value calculation method and program according to the embodiment can more accurately evaluate the level of comfort of people in the target space SP1. Therefore, it becomes possible to achieve energy conservation to the extent that the comfort of people in the target space SP1 is not compromised, thereby achieving both comfort and energy conservation.

[0102] The control method according to the embodiment includes an environmental comfort level calculation step ST11, a congestion level calculation step ST12, an attention level calculation step ST13, an evaluation value calculation step ST14, and an air conditioning control step ST21. In the environmental comfort level calculation step ST11, the environmental comfort level E00 is calculated based on the state of the target space SP1.

In the evaluation value calculation step ST14, a comfort evaluation value K0 is calculated based on the environmental comfort level E00, the congestion level C00, and the attention level B00. In the air conditioning control step ST21, the air conditioning unit 30 of the target space SP1 is controlled. In the air conditioning control step ST21, the air conditioning unit 30 is controlled based on the comfort evaluation value K0 so as to reduce the power consumption of the air conditioning unit 30. The program according to the embodiment causes one or more processors to execute the control method according to the embodiment.

[0103] As a result, the control method and program according to this embodiment can more accurately evaluate the level of comfort of people in the target space SP1. Therefore, it becomes possible to save energy without compromising the comfort of people in the target space SP1, thus achieving both comfort and energy saving.

[0104] (Other modifications according to the embodiment) (1) In this embodiment, the air conditioning control unit 20 of the control system 100 and the comfort evaluation value calculation system 10 operate synchronously, but the operating timing of the air conditioning control unit 20 of the control system 100 and the operating timing of the comfort evaluation value calculation system 10 may be different. For example, the comfort evaluation value calculation system 10 may calculate the comfort evaluation value K0 at a predetermined period, and the air conditioning control unit 20 of the control system 100 may operate as a trigger when the comfort evaluation value K0 satisfies predetermined conditions. The predetermined conditions are, for example, that the comfort evaluation value K0 is below a threshold, and that the amount of change in the comfort evaluation value K0 exceeds a reference value.

[0105] (2) In this embodiment, the environmental comfort level calculation unit 11 calculates the environmental comfort level E00 based on the temperature and humidity of the target space SP1. However, the environmental comfort level calculation unit 11 may also obtain, for example, the wind speed of the indoor air, odor, carbon dioxide level, etc. from sensors and use them to calculate the environmental comfort level E00.

[0106] (3) In this embodiment, the environmental comfort level calculation unit 11 calculates the second comfort level E5 from the frequency of statements indicating discomfort. However, the second comfort level E5 may also be calculated based on the frequency of statements indicating comfort. The environmental comfort level calculation unit 11 detects the frequency of statements indicating comfort, such as "cool," and sets the second comfort level E5 such that the value of the second comfort level E5 approaches 1 as the frequency of such statements increases, and the value of the second comfort level E5 approaches 0 as the frequency of such statements decreases.

However, for example, the second attention level may be further calculated based on the facial expression of the person in the target space SP1. For example, the attention level calculation unit 13 acquires an image captured in the target space SP1 from the camera 45, analyzes the person's facial expression, and evaluates the intensity of the person's emotion on a scale of 0 to 4. The attention level calculation unit 13 outputs a normalized value obtained by dividing the evaluation result by 4 as the second attention level B5. The second attention level B5 is used to calculate the attention level B00, similar to the second attention levels B1 to B4.
