In each drawing, the same components are designated by the same reference numerals.

[0022] 1 is a plan view of the first floor of a building 100 as one embodiment of a building according to the present invention. First, an overview of the building 100 of this embodiment will be described.

[0023] The building 100 may be, for example, a detached house having a steel frame structure. The building 100 in this embodiment is two-story, but the number of stories of the building 100 is not particularly limited. The building 100 may have three or more stories, or may have only one story.

[0024] The building 100 of this embodiment is composed of a reinforced concrete foundation, and a superstructure having a framework made up of framework members such as columns and beams and fixed to the foundation. The superstructure of this embodiment has a steel framework, but may have a wooden framework, and its structure is not particularly limited. The framework members that make up the framework of the building 100 of this embodiment are standardized in advance and are manufactured in a factory beforehand and then transported to the construction site and assembled.

[0025] Specifically, exterior materials constituting the exterior wall 101 are arranged on the outer periphery of the framework of the upper structure of the building 100 of this embodiment. Additionally, floor slab materials constituting the floor are arranged between the layers of the framework. Furthermore, roof floor slab materials constituting a flat roof are arranged on the upper part of the framework.

[0026] The exterior wall 101 of the building 100 of this embodiment has an exterior finishing layer formed by connecting panel-shaped exterior materials made of lightweight aerated concrete (ALC) with a coating film formed as a waterproof layer on the outer surface. The exterior wall 101 of the building 100 of this embodiment also has an interior finishing layer formed by, for example, a plaster board and a finishing material such as wall cloth attached to the surface of the plaster board.

[0034] As shown in Fig. 1, on the first floor of a building 100 of this embodiment, a corridor 12 and a washroom 14 are adjacent to each other via a partition wall 22. The partition wall 22 does not have an entrance, but may have an entrance with a fixture.

[0035] As shown in Fig. 1, the washroom 14 and the bathroom 15 are adjacent to each other via a partition wall 23. An entrance 23a is formed in the partition wall 23, allowing access between the washroom 14 and the bathroom 15. A door such as a hinged door or a sliding door is provided in the entrance 23a as a fixture 23b.

[0036] As shown in FIG. 1, on the first floor of the building 100 of this embodiment, the corridor 12 and the living / dining / kitchen area 16 are adjacent to each other via a partition wall 24. The partition wall 24 is formed with an entrance 24a through which the corridor 12 and the living / dining / kitchen area 16 can come and go. A door such as a hinged door or a sliding door is disposed in the entrance 24a as a fixture 24b. The living / dining / kitchen area 16 includes a kitchen space 16a, a dining space 16b, and a living space 16c. The entrance 24a is disposed at a position that allows passage between the corridor 12 and the dining space 16b of the living / dining / kitchen area 16c.

[0037] As shown in Fig. 1, on the first floor of the building 100 of this embodiment, the washroom 14 and the living / dining / kitchen area 16 are adjacent to each other via a partition wall 28 extending from the partition wall 24. The partition wall 28 is formed with an entrance / exit 28a through which the washroom 14 and the living / dining / kitchen area 16 can come and go. A door such as a hinged door or a sliding door is disposed in the entrance / exit 28a as a fixture 28b. The entrance / exit 28a is disposed in a position that allows the washroom 14 and the dining space 16b of the living / dining / kitchen area 16 to come and go.

[0038] As shown in Fig. 1, on the first floor of the building 100 of this embodiment, the entrance 11 and the living / dining / kitchen area 16 are adjacent to each other via a partition wall 25 extending from the above-mentioned partition wall 24. The partition wall 25 has an entrance 25a through which the entrance 11 and the living / dining / kitchen area 16 can come and go. A door such as a hinged door or a sliding door is disposed in the entrance 25a as a fixture 25b. The above-mentioned entrance 25a is disposed in a position that allows passage between the entrance 11 and the living space 16c of the living / dining / kitchen area 16.

[0039] 1, in the living / dining / kitchen area 16 of this embodiment, a kitchen space 16a, a dining space 16b, and a living space 16c are arranged in a row. The dining space 16b and the living space 16c are connected to each other, but for example, a movable partition wall that can separate the dining space 16b and the living space 16c may be arranged.

[0040] As shown in Fig. 1, the entrance hall 11 and the hallway 12 in this embodiment are adjacent to each other. The entrance hall 11 and the hallway 12 in this embodiment are configured to be able to partition each other. Specifically, an entrance 26a with a fitting 26b is disposed between the entrance hall 11 and the hallway 12 in this embodiment. Therefore, by opening the fitting 26b, the entrance hall 11 and the hallway 12 communicate with each other. Conversely, by closing the fitting 26b, the entrance hall 11 and the hallway 12 can be partitioned.

[0041] As shown in Fig. 1, the corridor 12 and the staircase 41 in this embodiment are adjacent to each other. The corridor 12 and the staircase 41 in this embodiment are configured to be able to partition each other. Specifically, an entrance / exit 27a with a fitting 27b is disposed between the corridor 12 and the staircase 41 in this embodiment. Therefore, by opening the fitting 27b, the corridor 12 and the staircase 41 communicate with each other. Conversely, by closing the fitting 27b, the corridor 12 and the staircase 41 can be partitioned.

[0042] Next, the air conditioning of the corridor 12 and the toilet 13 will be described with reference to FIG.

[0043] As shown in FIG. 2, the building 100 is provided with an air conditioner 50 having an outlet 51 capable of blowing air toward the corridor 12. The air conditioner 50 may be, for example, an air conditioner capable of heating and cooling the corridor 12. The "air conditioner 50" referred to here means an indoor unit. The indoor unit as the air conditioner 50 is connected by piping to an outdoor unit 52 disposed outdoors. The outdoor unit 52 may be disposed, for example, adjacent to the outside of an exterior wall that separates the toilet 13 from the outdoor space.

[0044] The air conditioner 50 of this embodiment is disposed above the toilet 13. The air outlet 51 of the air conditioner 50 is configured to be able to blow air toward the corridor 12 from the upper position of the partition wall 21 between the corridor 12 and the toilet 13.

[0045] As shown in FIG. 2, the building 100 is provided with a communication passage 60 that communicates the corridor 12 and the toilet 13. As shown in FIG. 2, the communication passage 60 of this embodiment communicates the corridor 12 and the toilet 13 through the upper part of the air conditioner 50. More specifically, in the building 100 of this embodiment, the communication passage 60 is formed in the ceiling space above the corridor 12 and the toilet 13 adjacent to each other through the partition wall 21. The communication passage 60 of this embodiment extends from an air vent 61 formed on the ceiling surface of the corridor 12 and opening into the corridor 12, through the ceiling space, to an air vent 62 formed on the ceiling surface of the toilet 13 and opening into the toilet 13. In addition, the building 100 of this embodiment is provided with a duct 65 that extends from the air vent 61 of the communication passage 60 that opens into the corridor 12 to the air vent 62 of the communication passage 60 that opens into the toilet 13. Therefore, the corridor 12 and the toilet 13 in this embodiment are configured to be ventilated through a duct 65 arranged in the communication passage 60.

[0046] As shown in FIG. 2, the building 100 is provided with an air supply device 70 capable of supplying air from the corridor 12 to the toilet 13 through the communication passage 60. The air supply device 70 may be, for example, an electric air supply fan. The air supply device 70 of this embodiment is configured to be capable of supplying air from the corridor 12 to the toilet 13 through a duct 65. The arrangement position of the air supply device 70 is not particularly limited as long as it is capable of supplying air from the corridor 12 to the toilet 13 through the communication passage 60. Therefore, the air supply device 70 may be arranged, for example, at the position of the vent 61 as an exhaust port opening into the corridor 12. The air supply device 70 may also be arranged, for example, at the position of the vent 62 as an air supply port opening into the toilet 13. Furthermore, the air supply device 70 may also be arranged, for example, at both the position of the vent 61 and the position of the vent 62.

[0047] As described above, the building 100 is equipped with an air conditioner 50 capable of conditioning the corridor 12. Furthermore, the building 100 is configured so that the conditioned air in the corridor 12, which has been conditioned by the air conditioner 50, can be supplied to the toilet 13 via the communication passage 60 by the air supply device 70. Therefore, the toilet 13 can be efficiently and integrally air-conditioned together with the corridor 12 without the need to install a heater or the like for heating only the toilet 13.

[0048] As described above, the air conditioner 50 of this embodiment is disposed above the toilet 13, but the location of the air conditioner 50 is not particularly limited as long as the air conditioner 50 is provided with an outlet 51 capable of blowing air toward the corridor 12. Therefore, the air conditioner 50 may be disposed, for example, above the washroom 14. In such a case, the outlet 51 of the air conditioner 50 may be configured to be capable of blowing air toward the corridor 12 from the upper position of the partition wall 22 between the corridor 12 and the washroom 14. However, as in this embodiment, when the outdoor unit 52 is disposed adjacent to the exterior wall 101 that separates the toilet 13 from the outdoor space, it is preferable that the air conditioner 50 is disposed above the toilet 13. In this way, the piping connecting the air conditioner 50 and the outdoor unit 52 can be easily arranged.

[0049] The position of the vent 61 as an exhaust port that opens into the corridor 12 in the communication passage 60 is not particularly limited as long as it is configured to open into the corridor 12. However, it is preferable that the vent 61 as an exhaust port is disposed in a position close to the outlet 51 of the air conditioner 50. More specifically, as shown in FIG. 3, it is preferable that the vent 61 as an exhaust port is disposed within a range of a radius of 1.5 mm or less from the widthwise center position P1 of the outlet 51 of the air conditioner 50 in a plan view (see the dashed semicircle in FIG. 3). In this way, the conditioned air blown from the outlet 51 is easily supplied to the toilet 13 through the communication passage 60, and it is easy to air-condition the corridor 12 and the toilet 13 together.

[0050] As described above, the communication passage 60 of this embodiment passes above the air conditioner 50 to communicate with the corridor 12 and the toilet 13. More specifically, the communication passage 60 of this embodiment extends across the air conditioner 50 in the ceiling space above the corridor 12 and the toilet 13 as shown in FIG. 3. However, the arrangement of the communication passage 60 is not limited to the arrangement shown in FIG. 3. The communication passage 60 may be arranged at a position horizontally adjacent to the air conditioner 50, for example, as shown in FIG. 4. That is, the vent 61 as an exhaust port of the communication passage 60 may be formed at a position horizontally adjacent to the air conditioner 50 in the partition wall 21 that separates the corridor 12 and the toilet 13. However, as described above, the vent 61 as an exhaust port that opens into the corridor 12 is preferably arranged at a position close to the outlet 51 of the air conditioner 50. From this viewpoint, it is preferable that the communication passage 60 passes above the air conditioner 50 to communicate with the corridor 12 and the toilet 13 as in this embodiment. By doing so, it becomes easier to arrange the vent 61 serving as an exhaust port in a position close to the air outlet 51 of the air conditioner 50 on the ceiling surface of the corridor 12.

[0051] Next, the air conditioning control of the corridor 12 and the toilet 13 in the building 100 of this embodiment will be described.

[0052] Fig. 5 is a diagram showing the configuration of the air conditioner 50, the temperature sensor 80, and the control device 90. As shown in Fig. 5, the air conditioner 50 of this embodiment includes a control unit 53, a communication unit 54, and a power source 55. The communication unit 54 is configured to be capable of wired or wireless communication with a communication unit 92 of the control device 90, which will be described later. The control unit 53 can control the operation of the air conditioner 50 so that the temperature of the corridor 12 becomes a predetermined target temperature. The control unit 53 can also switch the power source 55 of the air conditioner 50 from an off state to an on state based on operation command information for the air conditioner 50 received from the control device 90.

[0053] As shown in FIG. 1, the building 100 of this embodiment includes a temperature sensor 80 capable of detecting the temperature of the corridor 12. The temperature sensor 80 may be attached to, for example, a wall surface that defines the corridor 12. As shown in FIG. 5, the temperature sensor 80 includes a temperature detection unit 81, a control unit 82, and a communication unit 83. The temperature detection unit 81 is configured to be capable of detecting the temperature of the corridor 12. The communication unit 83 is configured to be capable of wired or wireless communication with a communication unit 92 of a control device 90, which will be described later. The control unit 82 transmits information related to the detected temperature of the corridor 12 detected by the temperature detection unit 81 to the control device 90 via the communication unit 83.

[0054] The building 100 of this embodiment also includes a control device 90 capable of communicating with the air conditioner 50 and the temperature sensor 80. As shown in FIG. 1 and FIG. 2, the control device 90 may be attached to a wall partitioning the living / dining / kitchen area 16, for example. The control device 90 may be configured to include, for example, a Panasonic product "AiSEG2" (registered trademark) or the like. More specifically, as shown in FIG. 5, the control device 90 of this embodiment includes a control unit 91, a communication unit 92, and a clock unit 93 capable of detecting time. The communication unit 92 is configured to be capable of wired or wireless communication with the air conditioner 50 and the temperature sensor 80. More specifically, the communication unit 92 is capable of receiving information regarding the detected temperature of the corridor 12 from the temperature sensor 80. The communication unit 92 is capable of transmitting operation command information for the air conditioner 50 to the air conditioner 50. The control unit 91 determines whether or not to transmit operation command information for the air conditioner 50 to the air conditioner 50 based on information regarding the detected temperature of the corridor 12 received from the temperature sensor 80. As described above, the air conditioner 50 switches the power supply 55 of the air conditioner 50 from an off state to an on state based on operation command information for the air conditioner 50 received from the control device 90.

[0055] The control unit 53 of the air conditioner 50, the control unit 82 of the temperature sensor 80, and the control unit 91 of the control device 90 described above each include a processor, such as a general-purpose processor such as a CPU (central processing unit) or MPU (Micro Processing Unit), or a dedicated processor specialized for a specific process. Furthermore, the communication unit 54 of the air conditioner 50, the communication unit 83 of the temperature sensor 80, and the communication unit 92 of the control device 90 described above each are one or more communication interfaces. The communication interface may be, for example, a wired LAN interface, a wireless LAN interface, etc. "LAN" is an abbreviation for Local Area Network.

[0056] In this way, the air conditioner 50 of this embodiment is configured so that the power supply 55 can be automatically switched from an OFF state to an ON state based on the temperature detected by the temperature sensor 80. Below, an example of controlling the operation of the air conditioner 50 will be described with reference to Figures 6A and 6B.

[0057] FIG. 6A is a diagram showing a temperature detected by the temperature sensor 80. FIG. 6B is a diagram showing an example of control for switching the power supply 55 of the air conditioner 50 from an off state to an on state. As shown in FIG. 6A and FIG. 6B, the power supply 55 of the air conditioner 50 in this embodiment is automatically switched from an off state to an on state when the temperature sensor 80 detects a temperature equal to or lower than a predetermined temperature T1 between 0:00 and 8:00. More specifically, in this embodiment, when the temperature sensor 80 detects a temperature equal to or lower than a predetermined temperature T1 (for example, 18 degrees), the power supply 55 of the air conditioner 50 is switched from an off state to an on state. Then, air conditioning by the air conditioner 50 is started so that the temperature detected by the temperature sensor 80 becomes a predetermined target temperature T2 (for example, 21 degrees) higher than the predetermined temperature T1.

[0058] In the example shown in Fig. 6B, power supply 55 of air conditioner 50 is turned off at midnight. Also, in the example shown in Fig. 6A, the temperature detected by temperature sensor 80 is higher than predetermined temperature T1 at midnight. The occupant goes to sleep in this state.

[0059] Thereafter, as shown in Fig. 6A, when the temperature detected by the temperature sensor 80 falls below a predetermined temperature T1, the control device 90 transmits operation command information to the air conditioner 50. As a result, the control unit 53 of the air conditioner 50 switches the power of the air conditioner 50 from an OFF state to an ON state. The set temperature of the air conditioner 50 is set in advance to a target temperature T2. Therefore, when the power of the air conditioner 50 is turned ON, the control unit 53 of the air conditioner 50 starts controlling the operation of the air conditioner 50 so that the temperature of the hallway 12 becomes the target temperature T2.

[0060] This makes it possible to prevent the hallway 12 and the toilet 13 from being at a temperature lower than the predetermined temperature T1 when, for example, a resident goes to the toilet 13 at night or when the resident wakes up. Therefore, it is possible to prevent a resident from feeling cold in the hallway 12 and the toilet 13 when going to the toilet 13 from the living / dining / kitchen area 16 or a bedroom at night or early in the morning, and to prevent adverse effects on the body due to temperature differences, such as heat shock.

[0061] The power supply 55 of the air conditioner 50 may be switched from the on state to the off state manually by the resident. Therefore, the resident can manually switch the power supply 55 of the air conditioner 50 to the off state, for example, when going out after getting up. Figures 6A and 6B show an example in which the power supply 55 of the air conditioner 50 is manually switched from the on state to the off state at 9:00 when the resident goes out.

[0062] In order to prevent the power supply 55 of the air conditioner 50 from unintentionally switching from an off state to an on state while the resident is out, the control device 90 of this embodiment is configured to be able to send operation command information to the air conditioner 50 only during the time period from midnight to 8:00. In other words, the control device 90 of this embodiment is configured not to send operation command information to the air conditioner 50 unless the clock unit 93 detects the time between midnight and 8:00, even if the detected temperature received from the temperature sensor 80 is equal to or lower than the predetermined temperature T1. Therefore, the air conditioner 50 of this embodiment is configured not to automatically switch from an off state to an on state except during the time period between midnight and 8:00.

[0063] However, the automatic control of the power supply 55 of the air conditioner 50 from an OFF state to an ON state is not limited to the above example. The time period during which the power supply 55 of the air conditioner 50 can be automatically switched from an OFF state to an ON state can be set as appropriate, and for example, may be set to another time period instead of or in addition to the above-mentioned 0:00 to 8:00. An example of another time period is the time period before or after the resident returns home. In other words, a predetermined time period (e.g., 17:00 to 19:00) including the resident's usual return time (e.g., 18:00) may be set as a time period during which the power supply 55 of the air conditioner 50 can be automatically switched from an OFF state to an ON state, in addition to the above-mentioned 0:00 to 8:00.

[0064] As shown in Figs. 1 and 2, the building 100 of this embodiment is provided with an air conditioner 150 that is installed in the living / dining / kitchen area 16 and has an outlet 151 capable of blowing air toward the living / dining / kitchen area 16. The air conditioner 150 may be, for example, an air conditioner capable of heating and cooling the living / dining / kitchen area 16. The "air conditioner 150" referred to here means an indoor unit. The indoor unit as the air conditioner 150 is connected by piping to an outdoor unit 152 that is placed outdoors. The outdoor unit 152 may be, for example, placed adjacent to the outside of an exterior wall that separates the living / dining / kitchen area 16 from the outdoor space.

[0065] As shown in FIG. 1, the building 100 of this embodiment includes a temperature sensor 180 capable of detecting the temperature of the living room / dining kitchen 16. The temperature sensor 180 may be attached to, for example, a wall surface that partitions the living room / dining kitchen 16. The temperature sensor 180 has a configuration similar to that of the temperature sensor 80 described above. Therefore, the power supply of the air conditioner 150 installed in the living room / dining kitchen 16 may be automatically switched from the off state to the on state based on the temperature detected by the temperature sensor 180, similar to the air conditioner 50 described above. The power supply of the air conditioner 150 may be automatically switched from the off state to the on state under the same conditions as the air conditioner 50, for example. That is, as shown in FIG. 6A, the power supply of the air conditioner 150 may be automatically switched from the off state to the on state when the temperature sensor 180 detects a temperature equal to or lower than a predetermined temperature T1 between 0:00 and 8:00.

[0066] Next, an embodiment of a method for renovating an existing building according to the present invention will be described. Fig. 7 is a plan view of the first floor of an existing building 100A before renovation. Fig. 8 is a plan view of the first floor of a renovated building 100B obtained by renovating the existing building 100A shown in Fig. 7.

[0067] As shown in Fig. 7, the first floor of the existing building 100A before renovation is equipped with an entrance hall 11, a corridor 12, a toilet 13, a washroom 14, a bathroom 15, and a living / dining / kitchen area 16, similar to the building 100 shown in Fig. 1. Also, as shown in Fig. 7, the first and second floors of the existing building 100A are connected by a staircase 41a of a stairwell 41, similar to the building 100 shown in Fig. 1, and it is possible to move between them using the staircase 41a.

[0068] The existing building 100A shown in FIG. 7 differs from the above-described building 100 in the following five configurations. (I) There is no air conditioner 50 for cooling the corridor 12. (II) There is no communication passage 60 and air supply device 70 connecting the corridor 12 and the toilet 13. (III) The temperature sensors 80, 180 are not installed in the hallway 12 and the living / dining / kitchen area 16, and the control device 90 is not installed in the living / dining / kitchen area 16. (IV) The entrance hall 11 and the corridor 12 are always connected. (V) The corridor 12 and the staircase 41 are always connected.

[0069] In contrast, in the renovated building 100B shown in FIG. 8, the above items (I) to (V) have been renovated.

[0070] Specifically, in the renovated building 100B, an air conditioner 50 is newly installed to air-condition the corridor 12. The installation position of this air conditioner 50 is the same as that of the above-mentioned building 100, so a description thereof will be omitted here.

[0071] Furthermore, in the renovated building 100B, a communication passage 60 that connects the hallway 12 and the toilet 13 has been newly formed. Also, in the renovated building 100B, an air supply device 70 that can supply air from the hallway 12 to the toilet 13 through the newly formed communication passage 60 has been newly installed. The location of the communication passage 60 is the same as in the above-described building 100, so a description thereof will be omitted here. Also, the configuration and location of the air supply device 70 are the same as in the above-described building 100, so a description thereof will be omitted here.

[0072] In other words, the method of renovating an existing building 100A in this embodiment includes an air conditioner installation process of installing an air conditioner 50 equipped with an outlet 51 capable of blowing air toward the corridor 12, a connecting passageway forming process of forming a connecting passageway 60 that connects the corridor 12 and the toilet 13, and an air supply device installation process of installing an air supply device 70 that can blow air from the corridor 12 toward the toilet 13 through the connecting passageway 60.

[0073] In the air conditioner installation process of this embodiment, the air conditioner 50 is installed above the toilet 13 so that the air outlet 51 of the air conditioner 50 can blow air toward the corridor 12 from the upper position of the partition wall 21 (see Figure 2, etc.).

[0074] Furthermore, in the communication passage forming process of this embodiment, a communication passage 60 is formed so as to pass through the upper part of the air conditioner 50 and communicate between the corridor 12 and the toilet 13 (see FIG. 2, etc.). Furthermore, in the communication passage forming process of this embodiment, an air vent 61 that opens into the corridor 12 of the communication passage 60 is formed within a range of a radius of 1.5 mm or less from the widthwise center position of the air outlet 51 of the air conditioner 50 in a plan view (see FIG. 3, etc.).

[0075] In this way, in the renovated building 100B, the hallway 12 can be air-conditioned by the air conditioner 50. Also, in the renovated building 100B, a communication passageway 60 is formed and an air supply device 70 is disposed, so that air conditioned in the hallway 12 by the air conditioner 50 can be actively supplied to the toilet 13 through the communication passageway 60. In other words, the hallway 12 and the toilet 13 can be air-conditioned efficiently and integrally.

[0076] Furthermore, in the renovated building 100B, a temperature sensor 80 has been newly installed in the hallway 12. Furthermore, in the renovated building 100B, a temperature sensor 180 has been newly installed in the living / dining / kitchen area 16. Furthermore, in the renovated building 100B, a control device 90 has been newly installed in the living / dining / kitchen area 16. The method of using the temperature sensors 80, 180 and the control device 90 is similar to that of the building 100 described above, and therefore a description thereof will be omitted here.

[0077] In addition, in the renovated building 100B, an entrance 26a with a fitting 26b is formed between the entrance 11 and the corridor 12. As a result, by opening the fitting 26b, the entrance 11 and the corridor 12 communicate with each other. Conversely, by closing the fitting 26b, the entrance 11 and the corridor 12 can be partitioned.

[0078] Furthermore, in the renovated building 100B, an entrance 27a with a fitting 27b is formed between the corridor 12 and the stairwell 41. As a result, by opening the fitting 27b, the corridor 12 and the stairwell 41 communicate with each other. Conversely, by closing the fitting 27b, the corridor 12 and the stairwell 41 can be partitioned.

[0079] In this way, in the renovated building 100B of this embodiment, the corridor 12 is configured to be partitionable from the surrounding space including the entrance 11 and the staircase 41. This improves the air-conditioning efficiency of the corridor 12 by the air conditioner 50 in the renovated building 100B.

[0080] In particular, the existing building 100A and the renovated building 100B are provided with the living room, living and dining room 16, which is adjacent to the corridor 12 through a partition wall 24. As shown in FIG. 8, the renovation of the existing building 100A in this embodiment further includes an insulation process for insulating the walls surrounding the corridor 12, the toilet 13, and the living room, living and dining room 16. In other words, in the renovated building 100B, insulation renovation is performed on the partition walls and outer walls surrounding the corridor 12, the toilet 13, and the living room, living and dining room 16, by adding or changing insulation materials. In FIG. 8, the insulation line L1 of the wall that has been insulated and renovated is shown by a thick solid line. The above-mentioned fittings 26b and 27b are arranged as part of this insulation renovation. In other words, by providing the fittings 26b and 27b, the insulation line L1 of the wall surrounding the corridor 12, the toilet 13, and the living room, living and dining room 16, can be made continuous. In addition, in the renovated building 100B of this embodiment, in addition to the walls surrounding the corridor 12, the toilet 13, and the living room / living room / dining room 16, the ceiling surfaces of the corridor 12, the toilet 13, and the living room / living room / dining room 16 are also insulated. In this way, by insulating the walls and ceiling surfaces surrounding the corridor 12, the toilet 13, and the living room / living room / dining room 16, it becomes easier to air-condition the entire corridor 12, the toilet 13, and the living room / living room / dining room 16 in an integrated manner using the air conditioners 50, 150. In other words, the temperature difference between the corridor 12, the toilet 13, and the living room / living room / dining room 16 can be suppressed.

[0081] In this embodiment, the living room, living / dining / kitchen area 16, is adjacent to the corridor 12 via a partition wall 24, but the configuration is not limited to this. The living room adjacent to the corridor 12 via a partition wall 24 may be, for example, a bedroom. Also, the living room adjacent to the corridor 12 via a partition wall 24 may be, for example, both the living / dining / kitchen area 16 and a bedroom.

[0082] The building and existing building renovation method of the present invention are not limited to the specific configurations and processes shown in the above-mentioned embodiments and variant examples, and various modifications, changes, substitutions, combinations, etc. are possible as long as they do not deviate from the scope of the claims.
