Description

[Technical field]

[0001] The present invention relates to a sensation method and a sensation device. [Background technology]

[0002] Patent Document 1 discloses a building performance prediction method and program for predicting solar radiation and thermal insulation performance of a target building.

[0003] Recent technological innovations have improved the insulation performance of newly built homes, and the energy-saving performance of air conditioning equipment installed in these homes has also improved. On the other hand, in order for existing homes to benefit from recent technological innovations, renovations are necessary to improve the insulation and energy-saving performance of existing homes. Home renovations require cost and time, and may require residents to temporarily move out of their homes. Such burdens act as barriers to residents' desire to renovate their homes. Residents are concerned that home renovations will not efficiently contribute to improving insulation and energy-saving performance, and such concerns make them hesitant to renovate their homes.

[0004] [Patent Document 1] JP 2023-94408 A Summary of the Invention [Problem to be solved by the invention]

[0005] Therefore, the present invention has been made in consideration of the above circumstances, and aims to motivate residents to renovate their homes in order to improve the insulation performance or energy-saving performance of their homes. [Means for solving the problem]

[0006] The following reference numbers in parentheses refer to Figures 1 and 2.

[0007] According to the invention of claim 1, A method for allowing residents to experience the improvement in the insulation performance of a house (1) through renovation, comprising: A first step of measuring the temperature inside the unconditioned house (1) with a thermometer (34) and recording the measured temperatures in a recorder (36) in chronological order; a second step of attaching a heat insulating sheet to an opening (11) of an outer shell (2) separating the inside of the house (1) from the outdoors, measuring the temperature inside the house (1) that is not air-conditioned with the thermometer (34), and recording the measured temperatures in chronological order in the recorder (36); a third step of controlling a radiant air-conditioner (30) inside the house (1) based on time-series data of the measured temperature measured in the first step, thereby reproducing the thermal environment inside the house (1) in the first step by the radiant air-conditioner (30), and having the resident wait inside the house (1); a fourth step of controlling a radiant air-conditioner (30) inside the house (1) based on time-series data of the measured temperature measured in the second step, thereby reproducing the thermal environment inside the house (1) in the second step by the radiant air-conditioner (30), and having the resident wait inside the house (1); A method of experiencing a sensation is provided, comprising:

[0008] According to the invention of claim 1 as described above, in the third step, the occupant can experience the thermal environment inside the house (1) before the insulating sheet is attached to the opening (11) of the outer skin (2). Since the insulating sheet simulates the improvement in the insulating performance of the house (1) due to remodeling, the occupant can experience the effect of the insulating performance of the unremodeled house (1) on the thermal environment inside the house (1). In the fourth step, the occupant can experience the thermal environment inside the house (1) after the insulating sheet is attached to the opening (11) of the outer skin (2). Since the insulating sheet simulates the improvement in the insulating performance of the house (1) due to remodeling, the occupant can experience the effect of the insulating performance of the remodeled house (1) on the thermal environment inside the house (1). Therefore, the occupants can experience a reproduction of the thermal environment inside the house (1) after the insulating sheet has been affixed to the opening (11) of the exterior skin (2) immediately after experiencing a reproduction of the thermal environment inside the house (1) before the insulating sheet has been affixed to the opening (11) of the exterior skin (2). Therefore, the occupants can realize that the insulating sheet contributes to a constant temperature inside the house (1), that is, that the renovation contributes to improving the insulating performance of the house (1).

[0009] According to the invention of claim 2, An experience device that allows residents to experience the improvement in the insulation performance of a house (1) through renovation, A heat insulating sheet that can be attached to and peeled off from an opening (11) of an outer shell (2) that separates the inside of the house (1) from the outdoors; a thermometer (34) arranged inside the house (1) and measuring a temperature inside the house (1); a recorder (36) for recording the temperatures measured by the thermometer (34) in chronological order; A radiant air conditioner (30) disposed inside the house (1); A control unit (32) that reproduces the thermal environment inside the house (1) at the time of measurement by the thermometer (34) by controlling the radiant air conditioner (30) based on time series data of the measured temperature measured by the recorder (36) is provided.

[0010] According to the invention of claim 3, A method for allowing residents to experience the improvement in the insulation performance of a house (1) through renovation, comprising: a first step of disposing a radiant air conditioner (30) in the house (1) facing the resident; a second step of operating the radiant air conditioner (30) after the first step to apply heat or cold to the occupant by the radiant air conditioner (30); a third step of operating the radiant air conditioner (30) at an operating intensity weaker than that of the radiant air conditioner (30) in the second step after the second step or after the first step and before the second step, thereby applying hot or cold heat to the occupant by the radiant air conditioner (30); A method of experiencing a sensation is provided, comprising:

[0011] According to the invention of claim 3 as described above, in the second step, the occupants are exposed to cold from the radiant air-conditioner (30) and feel cold. In the fourth step, the occupants are exposed to cold from the radiant air-conditioner (30) that is weaker than the cold from the second step and do not feel it to be so cold. The radiation of cold from the radiant air-conditioner (30) in the second step simulates the insulation performance of the unrenovated house (1) in winter. The radiation of cold from the radiant air-conditioner (30) in the fourth step simulates the insulation performance of the renovated house (1) in winter. By comparing the cold from the second step with the cold from the fourth step, the occupants can feel the improvement in the insulation performance of the house (1) as a result of the renovation. Similarly, by comparing the heat from the second step with the heat from the fourth step, the residents can experience the improvement in the insulation performance of the house (1) as a result of the renovation.

[0012] According to the invention of claim 4, there is provided a sensation method according to claim 3, comprising: In the second step, the operating intensity of the radiant air conditioner (30) is controlled based on the temperatures measured by an indoor thermometer (34) inside the house (1) and an outdoor thermometer (35) outside the house (1), the difference between the temperatures, and the thermal insulation performance value of the exterior of the house (1) before the renovation of the house (1). A method of experiencing the sensation is provided.

[0013] According to the invention of claim 4 as described above, the radiation of cold or hot heat by the radiant air conditioner (30) in the second step more faithfully simulates the insulation performance of an unrenovated house (1) in winter or summer.

[0014] According to the invention of claim 5, there is provided a sensation method according to claim 3 or 4, comprising: In the third step, the operating intensity of the radiant air conditioner (30) is controlled based on the temperatures measured by an indoor thermometer (34) inside the house (1) and an outdoor thermometer (35) outside the house (1), the difference between the temperatures, and the thermal insulation performance value of the exterior of the house (1) after the house (1) has been remodeled. A method of experiencing the sensation is provided.

[0015] According to the invention of claim 5 as described above, the radiation of cold or hot heat by the radiant air conditioner (30) in the fourth step more faithfully simulates the insulation performance of the renovated house (1) in winter or summer.

[0016] According to the invention of claim 6, A method for allowing residents to experience the improvement in the insulation performance of a house (1) through renovation in winter or summer, comprising: A step of installing a radiant air conditioner (30) on an indoor surface of an exterior shell (2) of the house (1); Thereafter, a step of having the resident live in the house (1) while continuing to radiate heat from the radiant air conditioner (30) in winter or while continuing to radiate cold heat from the radiant air conditioner (30) in summer; A method of experiencing a sensation is provided, comprising:

[0017] According to the invention of claim 6 as described above, in winter, when a resident lives in the house (1), the resident can feel the constant temperature inside the house (1) due to the heat radiation from the radiant air-conditioner (30). The heat radiation from the radiant air-conditioner (30) simulates the improvement in the insulation performance of the house (1) due to remodeling. Therefore, the heat radiation from the radiant air-conditioner (30) allows the resident to feel the improvement in the insulation performance of the house (1) due to the remodeling. Such a feeling affects the resident's impression, and the resident is motivated to remodel the house (1) to improve the insulation performance of the house (1). Similarly, in the summer, the radiant air conditioner (30) emits cold heat, which makes the occupants feel the improvement in the insulation performance of the house (1) due to the renovation. Such a feeling affects the occupants' impressions, and the occupants are motivated to renovate the house (1) in order to improve its insulation performance.

[0018] According to the invention of claim 7, A method for allowing residents to experience the improvement in the insulation performance of a house (1) through renovation, comprising: A step of attaching a heat insulating sheet to an opening (11) of an outer shell (2) of the house (1); Thereafter, a step of having the resident live in the house (1); A method of experiencing a sensation is provided, comprising:

[0019] According to the invention of claim 7 as described above, when a resident lives in the house (1), the resident can feel the constant temperature inside the house (1) due to the heat insulating performance of the heat insulating sheet. For example, in summer, the heat from the outside is not easily transmitted into the house (1) due to the heat insulating sheet, so the resident feels the inside of the house (1) cooler than when the heat insulating sheet is not installed. In winter, the heat from inside the house (1) is not easily leaked to the outside due to the heat insulating sheet, so the resident feels the inside of the house (1) warmer than when the heat insulating sheet is not installed. The heat insulating sheet simulates the improvement in the heat insulating performance of the house (1) due to remodeling. Therefore, the heat insulating sheet allows the resident to feel the improvement in the heat insulating performance of the house (1) due to remodeling. Such a feeling affects the resident's impression, and the resident is motivated to remodel the house (1) in order to improve the heat insulating performance of the house (1). Effect of the Invention

[0020] According to the present invention, an information processing device is provided that can motivate residents to remodel their homes in order to improve the insulation performance or energy-saving performance of the homes. [Brief description of the drawings]

[0021] [Figure 1] Figure 1 shows the house before the simple renovation was carried out. [Diagram 2] Figure 2 shows the house after simple renovations have been made. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] Hereinafter, the embodiments will be described with reference to the drawings. The features and technical effects of the embodiments will be understood from the following detailed description and drawings. However, the scope of the present invention is not limited to the embodiments disclosed below. The drawings are provided for illustrative purposes only, and therefore the scope of the present invention is not limited to the illustrations in the drawings.

[0023] <1. Overview> FIG. 1 is a diagram showing a residence 1 for an inhabitant. The residence 1 has an exterior skin 2 that separates the inside from the outside. The exterior skin 2 has an exterior wall, a top skin, a floor, a foundation rise, and an opening, etc. The top skin refers to the roof, attic, or ceiling of the top floor, etc. The opening refers to a window, a sash, a door, or an air vent, etc. An indoor space 10 such as a living room, a bedroom, a kitchen, a storage room, a corridor, a washroom, a toilet, or a bathroom faces the exterior skin 2, particularly the exterior wall 3 and the ceiling 4 of the top floor, and the exterior wall 3 is provided with a window 11, which is an opening.

[0024] The resident is considering remodeling the house 1, particularly its exterior wall 3, in order to improve the thermal insulation performance of the house 1, particularly its exterior wall 3, and is consulting with a remodeling contractor. In addition to the exterior wall 3, the resident is also considering remodeling the ceiling 4 or attic of the top floor, or both, as necessary. However, the resident is concerned that the remodeling of the house 1 will not efficiently contribute to improving the thermal insulation performance of the house 1. Therefore, with the permission of the resident, the remodeling contractor performs simple remodeling of the indoor space 10 as shown in FIG. 2, so that the resident can experience the improvement in the thermal insulation performance of the house 1 due to the remodeling before the remodeling. A simple remodeling is one in which the indoor space 10 after such a simple remodeling can be easily restored to its pre-remodel state. A simple remodeling will be described below.

[0025] <2. Simple repairs> The heat insulating sheet 20 is attached to the window 11 with a peelable adhesive. The heat insulating sheet 20 is peelable from the window 11. The adhesive may be a double-sided adhesive tape. The heat insulating sheet 20 has transparency and light-transmitting properties, or has light-blocking properties. The heat insulating sheet 20 may be made of, for example, an aerogel insulation material or a bubble cushioning material. The heat insulating sheet 20 may be attached to the indoor surface of the exterior wall 3 or the ceiling 4 of the top floor. In this case, the heat insulating sheet 20 is made of, for example, an aerogel insulation material, a bubble cushioning material, or an interior lining insulation material.

[0026] The heat insulating performance of the heat insulating sheet 20 may be selected based on the results of calculations performed by a computer aided design (CAD) function of a computer. Specifically, the computer uses the CAD function to display the design drawing of the house 1 and the design drawing after renovation on an input screen, and the renovation contractor operates the computer to select the components of the exterior skin 2 in the design drawing (e.g., the exterior wall, the top exterior skin, the floor, the foundation rise portion, or the opening). The computer calculates the heat insulating performance values ​​of the components of the exterior skin 2 (e.g., the heat transmission coefficient (U value), the thermal resistance value (R value), or the thermal conductivity (λ value)), and the heat insulating performance of the heat insulating sheet 20 may be selected based on the heat insulating performance values. The heat insulating performance values ​​of the components of the exterior skin 2 may be automatically obtained by the computer from a house history information system through a search based on various information of the components of the exterior skin 2.

[0027] A radiant air conditioner 30 is provided on the indoor surface of the exterior wall 3. The radiant air conditioner 30 may be provided on the entire indoor surface of the exterior wall 3, or may be provided on a part of the indoor surface of the exterior wall 3. The radiant air conditioner 30 may be provided on a window 11. The radiant air conditioner 30 may be provided on the ceiling 4 of the top floor. The radiant air conditioner 30 may be removable from the indoor surface of the exterior wall 3, the window 11, or the ceiling 4. The radiant air conditioner 30 may be portable.

[0028] The radiant air conditioner 30 is a radiant cooling machine, a radiant heater, or a radiant cooling and heating machine having a circulation circuit and a temperature regulator. The radiant air conditioner circulates a heat medium such as water or oil, whose temperature is adjusted to be lower than the body temperature of the human body, through a circulation circuit, and radiates the cold heat of the heat medium from the circulation circuit. The radiant heater circulates a heat medium, whose temperature is adjusted to be higher than the body temperature of the human body, through a circulation circuit, and radiates the hot heat of the heat medium from the circulation circuit. The radiant air conditioner has both the function of a radiant cooling machine and the function of a radiant heater. The radiant air conditioner 30 may be capable of adjusting the size of the radiant area. The radiant area refers to the range in which the radiant air conditioner 30 radiates hot or cold heat.

[0029] The radiant air conditioner 30 is controlled by a control unit 32. The control unit 32 controls the operation intensity of the radiant air conditioner 30.

[0030] The heat insulating sheet 20 and the radiant air conditioner 30 may be used together, or either one may be used.

[0031] The indoor thermometer 34 is disposed in the indoor space 10. The indoor thermometer 34 may be installed on an inner wall that separates the indoor space 10 from an adjacent indoor space, may be provided on the indoor surface of the outer wall 3, or may be separated from the inner wall and the outer wall 3. The indoor thermometer 34 may be disposed in the center of the indoor space 10. The indoor thermometer 34 measures the temperature of the indoor space 10 and outputs a signal representing the measured temperature to the recorder 36 and the control unit 32. The data transfer standard of the indoor thermometer 34 and the recorder 36 is not particularly limited, and may be, for example, a serial bus, USB (registered trademark), Bluetooth (registered trademark), BLE (Bluetooth Low Energy), Wi-Fi (registered trademark), or ZigBee (registered trademark). The same applies to the data transfer standard of the indoor thermometer 34 and the control unit 32.

[0032] The outdoor thermometer 35 is disposed outdoors. Preferably, the outdoor thermometer 35 is disposed outdoors near the indoor space 10. The outdoor thermometer 35 may be provided on the outdoor surface of the exterior wall 3, or may be separated from the exterior wall 3. The outdoor thermometer 35 measures the outdoor temperature and outputs a signal representing the measured temperature to the recorder 36 and the control unit 32. The data transfer standard of the outdoor thermometer 35 and the recorder 36 is not particularly limited, and the standard may be, for example, a serial bus, USB (registered trademark), Bluetooth (registered trademark), BLE (Bluetooth Low Energy), Wi-Fi (registered trademark), or ZigBee (registered trademark). The same applies to the data transfer standard of the outdoor thermometer 35 and the control unit 32.

[0033] The recorder 36 has a CPU, a GPU, a storage medium, a display, and the like. The recorder 36 may have the indoor thermometer 34 built in. The recorder 36 may be, for example, a smartphone, a tablet computer, a laptop computer, or a data logger. The recorder 36 inputs a signal from the indoor thermometer 34 and periodically records the indoor measured temperature in a storage medium at a short sampling period. In this way, the recorder 36 accumulates time-series data of the indoor measured temperature in the storage medium. The recorder 36 displays the indoor measured temperature on the display in real time based on the signal input from the indoor thermometer 34. The recorder 36 displays the indoor measured temperature on the display in real time based on the signal input from the indoor thermometer 34 as a numerical value, a scale, a mark (e.g., a sweat mark, a clothing mark, a bedding mark), an image, an illustration, a pattern, or a color. The recorder 36 visually displays the change in the indoor measured temperature as a function of time on the display. Similarly, the recorder 36 receives a signal from the outdoor thermometer 35 and periodically records the outdoor measured temperature in the storage medium at short sampling intervals, thereby accumulating time-series data of the outdoor measured temperature in the storage medium. Based on the signal received from the outdoor thermometer 35, the recorder 36 displays the outdoor measured temperature on the display in real time.

[0034] The recorder 36 can communicate with the control unit 32 wirelessly or via a wire. The communication standard between the recorder 36 and the control unit 32 is not particularly limited, and the standard may be, for example, a serial bus, USB, Bluetooth, BLE, Wi-Fi, ZigBee, or the like.

[0035] The device comprising the heat insulating sheet 20, the radiant air conditioner 30, the control unit 32, the indoor thermometer 34, the outdoor thermometer 35 and the recorder 36 is a sensory device.

[0036] <3. Experience the improved insulation performance> Below, we will explain a method of allowing residents to experience the improvement in the insulation performance of their home due to the renovation before the renovation, using at least one of the insulation sheet 20, radiant air conditioner 30, control unit 32, indoor thermometer 34, outdoor thermometer 35, and recorder 36.

[0037] (1) First experience method In summer or winter, a remodeling contractor or a resident attaches the heat insulating sheet 20 to the window 11. Furthermore, the remodeling contractor or a resident places an indoor thermometer 34 and a recorder 36 in the indoor space 10, and places an outdoor thermometer 35 outdoors. After that, the resident wears a wearable device such as a smart watch, a smart band (activity meter), or smart glasses, and lives in the house 1 for a predetermined period of time, such as one week. When the resident is in the indoor space 10, the resident can feel the constant temperature of the indoor space 10 due to the heat insulating performance of the heat insulating sheet 20. In summer, the heat from the outdoors is not easily transmitted to the indoor space 10 by the heat insulating sheet 20, so the resident feels the indoor space 10 to be cooler than when the heat insulating sheet 20 is not installed. In winter, the heat from the indoor space 10 is not easily leaked to the outdoors by the heat insulating sheet 20, so the resident feels the indoor space 10 to be warmer than when the heat insulating sheet 20 is not installed. The heat insulating sheet 20 simulates the improvement in the heat insulating performance of the house 1 by remodeling. Therefore, the heat insulating sheet 20 allows the resident to feel the improvement in the heat insulating performance of the house 1 due to the renovation. Such a feeling influences the resident's impression, and the resident is motivated to renovate the house 1 in order to improve the heat insulating performance of the house 1.

[0038] The indoor and outdoor temperatures measured by the thermometers 34, 35 are displayed on the recorder 36, allowing the occupant to visually grasp the thermal environment and thermostatic constant of the indoor space 10 caused by the insulating sheet 20 that simulates the insulating performance of the remodeled house 1. Therefore, the occupant can visually understand the superiority of the insulating performance of the remodeled house 1 from the viewpoint of the thermal environment of the indoor space 10. Note that the display of the indoor and outdoor temperatures by the recorder 36 may be implemented in the second to sixth sensation methods described below.

[0039] The resident's vital signs and sleep patterns are measured and displayed by the wearable device. Therefore, the resident can easily understand the effect of the heat insulating sheet 20, which simulates the heat insulating performance of the remodeled house 1, on the resident's health through the thermal environment of the indoor space 10. The vital signs refer to, for example, body temperature, pulse, blood pressure, or SpO2. The vital signs and sleep patterns measured by the wearable device may be transferred from the wearable device to the resident's smartphone by the Bluetooth standard, and the vital signs and sleep patterns may be displayed on the resident's smartphone. Therefore, the resident can understand the superiority of the heat insulating performance of the remodeled house 1 from the viewpoint of the vital signs and sleep patterns. The measurement and display of the vital signs and sleep patterns by the wearable device may be performed in the second to sixth sensation methods described later.

[0040] When the wearable device is an Augmented Reality (AR) glass, the wearable device may measure the surface temperature of the heat insulating sheet 20, calculate the temperature of the indoor space 10 based on the surface temperature of the heat insulating sheet 20, convert the color of the image of the indoor space 10 captured by the built-in camera of the wearable device to cool or warm colors based on the temperature of the indoor space 10, and display the color-converted image on the built-in display of the wearable device. If a resident watches such an image, the resident can easily understand the effect of the heat insulating sheet 20 simulating the heat insulating performance of the remodeled house 1 on the thermal environment of the indoor space 10. Therefore, the resident can visually understand the superiority of the heat insulating performance of the remodeled house 1 from the viewpoint of the thermal environment of the indoor space 10.

[0041] Finally, the remodeling contractor removes and collects the heat insulating sheet 20, the indoor thermometer 34, the outdoor thermometer 35 and the recorder 36.

[0042] (2) The second way of experiencing In winter, the remodeling contractor or resident installs the radiant air conditioner 30 on the indoor surface of the exterior wall 3 or on the ceiling 4 of the top floor. Furthermore, the remodeling contractor or resident places the control unit 32, the indoor thermometer 34, and the recorder 36 in the indoor space 10, and places the outdoor thermometer 35 outdoors. After that, when the radiant air conditioner 30 and the control unit 32 are started, the control unit 32 controls the operating intensity of the radiant air conditioner 30 to be weak, and the radiant air conditioner 30 radiates weak heat. The control unit 32 may feed back the indoor and outdoor measured temperatures from the thermometers 34 and 35, and control the operating intensity of the radiant air conditioner 30 based on the measured temperatures, the difference between them, and the insulation performance value. The insulation performance value refers to a value that represents the insulation performance of the exterior skin 2 that surrounds the indoor space 10 of the house 1 after renovation, and refers to, for example, the heat transmission coefficient (U value), the thermal resistance value (R value), or the thermal conductivity (λ value).

[0043] Thereafter, the resident lives in the house 1 for a predetermined period of time, such as one week. During the resident's stay, the radiant air-conditioner 30 continues to radiate weak heat. When the resident is in the indoor space 10, the resident can feel the constant temperature of the indoor space 10 due to the heat radiation from the radiant air-conditioner 30. Because it is winter, the heat radiation from the radiant air-conditioner 30 simulates the improvement in the insulation performance of the house 1 due to remodeling. Therefore, the heat radiation from the radiant air-conditioner 30 allows the resident to feel the improvement in the insulation performance of the house 1 due to remodeling.

[0044] Finally, the remodeling contractor removes and collects the radiant air conditioner 30, the control unit 32, the indoor thermometer 34, the outdoor thermometer 35 and the recorder 36.

[0045] (3) The third way of experiencing In summer, a remodeling contractor or a resident installs the radiant air conditioner 30 on the indoor surface of the exterior wall 3. Furthermore, the remodeling contractor or a resident places the control unit 32, the indoor thermometer 34, and the recorder 36 in the indoor space 10, and places the outdoor thermometer 35 outdoors. After that, when the radiant air conditioner 30 and the control unit 32 are started, the control unit 32 controls the operating intensity of the radiant air conditioner 30 to be weak, and the radiant air conditioner 30 radiates weak cold heat. The control unit 32 may feed back the indoor and outdoor measured temperatures from the thermometers 34 and 35, and control the operating intensity of the radiant air conditioner 30 based on the measured temperatures, the difference between them, and the insulation performance value. The insulation performance value refers to a value that represents the insulation performance of the exterior skin 2 that surrounds the indoor space 10 of the house 1 after renovation, and refers to, for example, the heat transmission coefficient (U value), the thermal resistance value (R value), or the thermal conductivity (λ value).

[0046] Thereafter, the resident lives in the house 1 for a predetermined period of time, such as one week. During the resident's stay, the radiant air-conditioner 30 continues to radiate weak cold heat. When the resident is in the indoor space 10, the resident can feel the constant temperature of the indoor space 10 due to the cold heat radiation from the radiant air-conditioner 30. The cold heat radiation from the radiant air-conditioner 30 simulates the improvement in the insulation performance of the house 1 due to remodeling. Therefore, the cold heat radiation from the radiant air-conditioner 30 allows the resident to feel the improvement in the insulation performance of the house 1 due to remodeling.

[0047] Finally, the remodeling contractor removes and collects the radiant air conditioner 30, the control unit 32, the indoor thermometer 34, the outdoor thermometer 35 and the recorder 36.

[0048] (4) The fourth way of experiencing The remodeling contractor places the radiant air conditioner 30 facing the resident in the indoor space 10. The remodeling contractor may also install the radiant air conditioner 30 on the indoor surface of the exterior wall 3 or on the ceiling 4 of the top floor. Furthermore, the remodeling contractor or the resident places the control unit 32, indoor thermometer 34, and recorder 36 in the indoor space 10, and places the outdoor thermometer 35 outdoors.

[0049] Thereafter, when the radiant air conditioner 30 and the control unit 32 are started, the control unit 32 controls the operating intensity of the radiant air conditioner 30 to be strong, and the radiant air conditioner 30 radiates strong heat. The control unit 32 may feed back the indoor and outdoor measured temperatures from the thermometers 34, 35, and control the operating intensity of the radiant air conditioner 30 based on the measured temperatures, the difference between them, and the insulation performance value. The insulation performance value here refers to a value that represents the insulation performance of the exterior skin 2 that surrounds the indoor space 10 of the house 1 before renovation, and refers to, for example, the coefficient of thermal transmission (U value), thermal resistance value (R value), or thermal conductivity (λ value).

[0050] When the occupants are exposed to strong heat from the radiant air-conditioner 30, they feel hot from the strong heat of the radiant air-conditioner 30. The strong heat radiation from the radiant air-conditioner 30 simulates the insulation performance of an unrenovated house 1 in the summer.

[0051] Thereafter, the control unit 32 controls the operating intensity of the radiant air conditioner 30 to be weaker than the previous strong operating intensity, and the radiant air conditioner 30 radiates weak heat. The control unit 32 may feed back the indoor and outdoor measured temperatures from the thermometers 34, 35, and control the operating intensity of the radiant air conditioner 30 based on the measured temperatures, the difference between them, and the insulation performance value. The insulation performance value here refers to a value that represents the insulation performance of the exterior skin 2 that surrounds the indoor space 10 of the house 1 after renovation, and refers to, for example, the coefficient of thermal transmission (U value), thermal resistance value (R value), or thermal conductivity (λ value). Even if the occupants are exposed to weak heat from the radiant air conditioner 30, they do not feel that hot due to the weak heat from the radiant air conditioner 30. The weak heat radiation from the radiant air conditioner 30 simulates the insulation performance of the renovated house 1 in the summer. As described above, by comparing the strong and weak heat radiation of the radiant air-conditioning unit 30, the occupants can feel the improvement in the insulation performance of the house 1 as a result of the renovation.

[0052] The order of weak warm heat radiation from the radiant air conditioner 30 and strong warm heat radiation from the radiant air conditioner 30 may be reversed. Weak warm heat radiation from the radiant air conditioner 30 and strong warm heat radiation from the radiant air conditioner 30 may be alternately repeated.

[0053] Finally, the remodeling contractor removes and collects the radiant air conditioner 30, the control unit 32, the indoor thermometer 34, the outdoor thermometer 35 and the recorder 36.

[0054] (5) The fifth way to experience The remodeling contractor places the radiant air conditioner 30 facing the resident in the indoor space 10. The remodeling contractor may also install the radiant air conditioner 30 on the indoor surface of the exterior wall 3 or on the ceiling 4 of the top floor. Furthermore, the remodeling contractor or the resident places the control unit 32, indoor thermometer 34, and recorder 36 in the indoor space 10, and places the outdoor thermometer 35 outdoors.

[0055] Thereafter, when the radiant air conditioner 30 and the control unit 32 are started, the control unit 32 controls the operating intensity of the radiant air conditioner 30 to be strong, and the radiant air conditioner 30 radiates strong cold. The control unit 32 may feed back the indoor and outdoor measured temperatures from the thermometers 34, 35, and control the operating intensity of the radiant air conditioner 30 based on the measured temperatures, their difference, and the insulation performance value. The insulation performance value here refers to a value that represents the insulation performance of the exterior skin 2 that surrounds the indoor space 10 of the house 1 before renovation, and refers to, for example, the coefficient of thermal transmission (U value), thermal resistance value (R value), or thermal conductivity (λ value).

[0056] When the occupants are exposed to the strong cold heat from the radiant air-conditioner 30, they feel cold from the strong cold heat of the radiant air-conditioner 30. The strong cold heat of the radiant air-conditioner 30 simulates the insulation performance of a house 1 that has not been renovated in winter.

[0057] Thereafter, the control unit 32 controls the operating intensity of the radiant air conditioner 30 to be weaker than the previous strong operating intensity, and the radiant air conditioner 30 radiates weak cold. The control unit 32 may feed back the indoor and outdoor measured temperatures from the thermometers 34, 35, and control the operating intensity of the radiant air conditioner 30 based on the measured temperatures, the difference between them, and the insulation performance value. The insulation performance value here refers to a value that represents the insulation performance of the exterior skin 2 that surrounds the indoor space 10 of the house 1 after renovation, and refers to, for example, the coefficient of thermal transmission (U value), thermal resistance value (R value), or thermal conductivity (λ value).

[0058] Even if the occupants are exposed to weak cold heat from the radiant air-conditioner 30, they do not feel that cold due to the weak cold heat from the radiant air-conditioner 30. The weak cold heat radiation from the radiant air-conditioner 30 simulates the insulation performance of the remodeled house 1 in winter. By comparing the strong cold heat radiation and the weak cold heat radiation from the radiant air-conditioner 30, the occupants can feel the improvement in the insulation performance of the house 1 due to the remodeling.

[0059] The order of weak cold radiation from the radiant air conditioner 30 and strong cold radiation from the radiant air conditioner 30 may be reversed. Weak cold radiation from the radiant air conditioner 30 and strong cold radiation from the radiant air conditioner 30 may be alternately repeated.

[0060] Finally, the remodeling contractor removes and collects the radiant air conditioner 30, the control unit 32, the indoor thermometer 34, the outdoor thermometer 35 and the recorder 36.

[0061] (6) The sixth way to experience In summer or winter, with the heat insulating sheet 20 not attached to the window 11, the temperature of the unconditioned indoor space 10 is measured by the indoor thermometer 34 for a predetermined period (e.g., one day). At that time, the indoor thermometer 34 outputs a signal representing the measured temperature to the recorder 36, which records the measured temperature in chronological order in a storage medium. Based on the signal input from the indoor thermometer 34, the recorder 36 instantly displays the measured temperature on the display as a numerical value, a scale, a mark (e.g., a sweat mark, a clothing mark, a bedding mark), an image, an illustration, a pattern, or a color. Therefore, the occupant can visually grasp the thermal environment of the indoor space 10 based on the heat insulating performance of the unrenovated house 1. It is not necessary for the occupant to be in the indoor space 10 all the time during the temperature measurement.

[0062] After the temperature measurement, the recorder 36 inputs the time series data of the measured temperature into a trained model that has been machine-learned using big data, thereby outputting text data containing health advice that takes into consideration the impact on the resident's health of the thermal environment of the indoor space 10 caused by the insulation performance of the unrenovated house 1, and displays the advice on the display based on the text data. Such advice gives the resident an awareness of the impact on the resident's health of the thermal environment of the indoor space 10 caused by the insulation performance of the unrenovated house 1.

[0063] Thereafter, with the heat insulating sheet 20 attached to the window 11, the unconditioned indoor space 10 is measured by the indoor thermometer 34 for a predetermined period (e.g., one day). At that time, the indoor thermometer 34 outputs a signal representing the measured temperature to the recorder 36, which records the measured temperature in chronological order in a storage medium. Based on the signal input from the indoor thermometer 34, the recorder 36 instantly displays the measured temperature on the display as a numerical value, a scale, a mark (e.g., a sweat mark, a clothing mark, a bedding mark), an image, an illustration, a pattern, or a color. Therefore, the occupant can visually grasp the thermal environment of the indoor space 10 with the heat insulating sheet 20 simulating the heat insulating performance of the renovated house 1. It is not necessary for the occupant to be in the indoor space 10 all the time during the temperature measurement.

[0064] After the measurement, the recorder 36 inputs the time series data of the measured temperature into a trained model that has been machine-learned using big data, thereby outputting text data containing health advice that takes into consideration the impact on the resident's health of the thermal environment of the indoor space 10 caused by the insulation performance of the renovated house 1, and displays the advice on the display based on the text data. Such advice gives the resident an awareness of the impact on the resident's health of the thermal environment of the indoor space 10 caused by the insulation performance of the renovated house 1.

[0065] Thereafter, time series data of the measured temperature when the insulating sheet 20 is not attached to the window 11 is transferred from the recorder 36 to the control unit 32. The control unit 32 controls the radiant air conditioner 30 based on the time series data of the measured temperature, so that the thermal environment of the indoor space 10 when the insulating sheet 20 is not attached to the window 11 is reproduced by the radiant air conditioner 30. The occupant is made to wait in the indoor space 10 during the reproduction. Therefore, the occupant can experience the thermal environment of the indoor space 10 when the insulating sheet 20 is not attached to the window 11. In other words, the occupant can experience the effect that the insulating performance of the unrenovated house 1 has on the thermal environment of the indoor space 10.

[0066] Subsequently, time series data of the measured temperature when the insulating sheet 20 is attached to the window 11 is transferred from the recorder 36 to the control unit 32. The control unit 32 controls the radiant air conditioner 30 based on the time series data of the measured temperature, so that the thermal environment of the indoor space 10 when the insulating sheet 20 is attached to the window 11 is reproduced by the radiant air conditioner 30. The occupant is made to wait in the indoor space 10 during the reproduction. Therefore, the occupant can experience the thermal environment of the indoor space 10 when the insulating sheet 20 is attached to the window 11. In other words, the occupant can experience the effect that the insulating performance of the remodeled house 1 has on the thermal environment of the indoor space 10.

[0067] The occupants can experience the reproduction of the thermal environment in the indoor space 10 when the insulating sheet 20 is attached to the window 11 immediately after experiencing the reproduction of the thermal environment in the indoor space 10 when the insulating sheet 20 is not attached to the window 11. Therefore, the occupants can realize that the insulating sheet 20 contributes to maintaining a constant temperature in the indoor space 10, that is, that the renovation contributes to improving the insulating performance of the house 1.

[0068] Finally, the remodeling contractor removes and collects the insulation sheet 20, the radiant air conditioner 30, the control unit 32, the indoor thermometer 34, the outdoor thermometer 35 and the recorder 36.

[0069] <4. Summary> The resident's experience through the above-mentioned sensory method affects the resident's impression, and the resident is motivated to remodel the house 1 in order to improve the insulation performance of the house 1.

[0070] If the resident renovates the house 1 as a result of this experience, it is possible to reduce the energy consumption of the house 1. Therefore, the above-mentioned experience method and experience device contribute to the promotion of carbon neutrality, the realization of a decarbonized society, and the achievement of the Sustainable Development Goals (SDGs).
