Embodiments for Carrying Out the Invention

[0014] Hereinafter, a renovation method according to the present invention and embodiments of a building will be exemplified and described with reference to the drawings. The same reference numerals are given to the common configurations in each figure.

[0015] FIG. 1 is a plan view of the first floor of the building 100 before renovation. FIG. 2 is a plan view of the second floor of the building 100 before renovation. FIG. 3 is a plan view of the first floor of the building 100 after renovation. Hereinafter, for the sake of convenience of explanation, the building 100 before renovation will be described as "building 100A", and the building 100 after renovation will be described as "building 100B". Also, when the building 100 is not particularly distinguished before and after renovation, it will be simply described as "building 100". First, an overview of the building 100 will be described.

[0016] The building 100 may be, for example, a single-family house having a steel frame structure. The building 100 of the present embodiment is a two-story building, but the number of floors of the building 100 is not particularly limited. The building 100 may have a configuration having three or more floors, or may have a configuration having only one floor.

[0017] The building 100 of the present embodiment has a foundation made of reinforced concrete and a frame structure composed of frame members such as columns and beams, and an upper structure fixed to the foundation. The upper structure of the present embodiment has a steel frame structure, but may have, for example, a wooden frame, and its structure is not particularly limited. Further, the frame members constituting the frame structure of the building 100 of the present embodiment are pre-standardized (standardized), manufactured in a factory in advance, and then transported to the construction site and assembled.

[0018] Specifically, exterior materials such as exterior finishing materials that constitute the outer wall are arranged on the outer peripheral portion of the frame structure of the superstructure of the building 100 of the present embodiment. Further, floor slab materials and the like that constitute the floor portion are arranged at the inter-story portions of the frame structure. Furthermore, roof floor slab materials and the like that constitute the flat roof are arranged on the upper portion of the frame structure.

[0019] The outer wall of the building 100 of the present embodiment includes, for example, an external finishing layer configured by connecting panel-shaped exterior materials made of lightweight cellular concrete (ALC) with a coating film as a waterproof layer formed on the outer surface side. Also, the outer wall of the building 100 of the present embodiment includes, for example, an internal finishing layer composed of a plaster boat and finishing materials such as wall cloth pasted on the surface of the gypsum board. Furthermore, the outer wall of the building 100 of the present embodiment may include a heat insulating material such as glass wool, rock wool, or a foamed resin panel between the external finishing layer and the internal finishing layer. However, the outer wall of the building 100 is not limited to this configuration.

[0020] The floor portion of the building 100 of the present embodiment includes a floor slab material. The floor slab material is installed between the beams of the frame structure and is directly or indirectly supported by the beams. As the floor slab material, for example, an ALC panel can be used, but other members such as folded plates, extruded cement plates, and wooden panel materials may also be used. The floor portion may, in addition to the floor slab material, include, for example, ceiling interior materials that constitute the ceiling surface of the lower floor and are directly or indirectly attached to the floor slab material, and floor interior materials such as flooring that are laminated on the floor slab material and constitute the floor surface of the upper floor.

[0021] Regarding the roof floor slab material that constitutes the flat roof, an ALC panel can also be used, but it is not limited to the ALC panel. Also, the roof floor slab material is waterproofed by being covered with, for example, a waterproof sheet formed from vinyl chloride resin. Also, the roof of the building is not limited to a flat roof and may be a pitched roof using roof exterior materials such as slate.

[0022] Next, with reference to FIGS. 1 and 2, the floor plan of the building 100A before renovation of the present embodiment will be described.

[0023] As shown in FIG. 1, the first floor of Building 100A includes an entrance 11, a first-floor corridor 12, a first-floor toilet 13, a washroom 14, a bathroom 15, a living-dining room 16, a kitchen 17, and a guest room 18.

[0024] As shown in FIG. 2, the second floor of Building 100A includes a second-floor corridor 31, a second-floor toilet 32, a second-floor storage room 33, a balcony 34, a bedroom 35, a first private room 36, and a second private room 37.

[0025] As shown in FIGS. 1 and 2, the first and second floors of Building 100A are connected by a staircase 41a in a staircase room 41, and it is possible to go back and forth using the staircase 41a. A storage space 41b is provided below the staircase 41a in the staircase room 41.

[0026] Hereinafter, the characteristics of the floor plans of each floor will be described in detail. In the following description of the floor plans, the terms "living room" and "non-living room" are used, so first, these terms will be explained.

[0027] The "living room" conforms to Article 2, Paragraph 4, Item 4 of the Building Standards Law, and means a room that is continuously used for purposes such as living, working, and entertainment. The "non-living room" means a room that does not fall under the living room.

[0028] In Building 100A of the present embodiment, the living-dining room 16, the kitchen 17, and the guest room 18 on the first floor fall under the living room. Also, in Building 100A, the bedroom 35, the first private room 36, and the second private room 37 on the second floor fall under the living room.

[0029] On the other hand, in Building 100A of the present embodiment, the entrance 11, the first-floor corridor 12, the first-floor toilet 13, the washroom 14, and the bathroom 15 on the first floor fall under the non-living room. Also, in Building 100A, the second-floor corridor 31, the second-floor toilet 32, and the second-floor storage room 33 on the second floor fall under the non-living room. Furthermore, the staircase room 41 of Building 100A in the present embodiment falls under the non-living room.

[0030] <Floor plan of the first floor of Building 100A> As shown in Fig. 1, on the first floor of the building 100A, a first-floor corridor 12 as a non-residential room continuous with the entrance 11 and the staircase room 41 is provided. The first-floor corridor 12 is communicably connected to a living-dining room 16 as a residential room. Also, the first-floor corridor 12 is communicably connected to a first-floor toilet 13 and a washroom 14, respectively, both of which are non-residential rooms.

[0031] Here, in this specification, when adjacent indoor spaces, specifically, between indoor residential rooms, between indoor non-residential rooms, or between indoor residential and non-residential rooms, are "continuous", it means a state in which at least a part of the adjacent indoor spaces is always in communication. Therefore, in the building 100A of this embodiment, the entrance 11 and the staircase room 41 are always in communication with the first-floor corridor 12.

[0032] Also, in this specification, when indoor spaces, specifically, between indoor residential rooms, between indoor non-residential rooms, or between indoor residential and non-residential rooms, are "connected", it means a state in which the adjacent indoor spaces are partitioned so as not to be always in communication. Specifically, when indoor spaces are "connected", they can be classified into the following three patterns. (1) Two adjacent indoor spaces are partitioned by a non-communicable partition wall. (2) Two adjacent indoor spaces are partitioned by a partition wall with an opening provided with a fixture. (3) Two adjacent indoor spaces are partitioned only by fixtures.

[0033] The "non-communicable partition wall" specified in (1) above corresponds to, for example, a partition wall without any opening including an entrance, a partition wall with a flush window formed, etc. The "partition wall with an opening provided with a fixture" specified in (2) above corresponds to, for example, a partition wall with an entrance provided with an arbitrary door such as a door leaf. (3) above is, for example, a state where there is no partition wall between two adjacent indoor spaces and only an entrance provided with an arbitrary door such as a door leaf exists between the two spaces.

[0034] As shown in FIG. 1, the first-floor corridor 12 of the present embodiment is connected to the living and dining room 16 so as to be accessible. Specifically, the first-floor corridor 12 of the present embodiment and the living and dining room 16 correspond to the above (2). That is, the first-floor corridor 12 of the present embodiment and the living and dining room 16 are partitioned by an intermediate partition wall 81 in which an entrance 51 provided with a door 51a as a door is formed. Further, the first-floor corridor 12 of the present embodiment and the living and dining room 16 are partitioned by another intermediate partition wall 82 in which an entrance 52 provided with a door 52a as a door is formed. Therefore, the first-floor corridor 12 of the present embodiment and the living and dining room 16 are connected so as to be accessible through the entrance 51 and the entrance 52.

[0035] Furthermore, as shown in FIG. 1, the first-floor corridor 12 of the present embodiment is connected to the first-floor toilet 13 so as to be accessible. Specifically, the first-floor corridor 12 of the present embodiment and the first-floor toilet 13 correspond to the above (2). That is, the first-floor corridor 12 of the present embodiment and the first-floor toilet 13 are partitioned by an intermediate partition wall 83 in which an entrance 53 provided with a door 53a as a door is formed.

[0036] Also, as shown in FIG. 1, the first-floor corridor 12 of the present embodiment is connected to the washroom 14 so as to be accessible. Specifically, the first-floor corridor 12 of the present embodiment and the washroom 14 correspond to the above (2). That is, the first-floor corridor 12 of the present embodiment and the washroom 14 are partitioned by an intermediate partition wall 84 in which an entrance 54 provided with a sliding door 54a as a door is formed.

[0037] In this way, in the building 100A, by passing through the first-floor corridor 12 as a non-residential room that is continuous with the entrance 11 and the staircase room 41 from the living and dining room 16 as a residential room, it is possible to go to and from the first-floor toilet 13, the washroom 14, and the bathroom 15 connected to this washroom 14.

[0038] Incidentally, the first-floor corridor 12 of the building 100A of the present embodiment is connected to the guest rooms 18 so as to be accessible in addition to the first-floor toilet 13 and the like described above. The first-floor corridor 12 and the guest rooms 18 are partitioned by an intermediate partition wall 96 in which an entrance 57 provided with a door 57a as a door is formed.

[0039] The living quarters of the present embodiment are configured to be heatable by a heating device. The heating device may be installed in each living quarter, for example. In contrast, the non-living quarters of the present embodiment are not configured to be heatable by a heating device. A heating device is not set in each non-living quarter of the present embodiment. Therefore, in winter, the living-dining room 16 as a living quarter is heated and warmed, whereas the first-floor corridor 12 as a non-living quarter continuous with the entrance hall 11 and the staircase room 41 is not heated and may get cold. Therefore, when a resident goes out into the first-floor corridor 12 from the living-dining room 16 toward any one of the first-floor toilet 13, the washroom 14, and the bathroom 15 in winter, there is a concern about the occurrence of heat shock due to a sudden temperature difference.

[0040] <Floor plan of Building 100B> In the building 100B shown in FIG. 3, the risk of occurrence of the above-described heat shock is reduced. Hereinafter, the renovation from the building 100A shown in FIG. 1 to the building 100B shown in FIG. 3 will be described.

[0041] As shown in FIG. 3, on the first floor of the building 100B, a moving area 12a located on the traffic line from the living-dining room 16 to the first-floor toilet 13 or the washroom 14 in at least the first-floor corridor 12, the entrance hall 11, and the staircase room 41 are partitioned by a door 2 as an openable and closable door. That is, in the renovation method of the building 100, a door such as an openable and closable door 2 is newly installed. Thereby, the moving area 12a and the entrance hall 11 or the staircase room 41 can be partitioned by the openable and closable door 2. Therefore, if the door 2 is in a closed state, even in winter, the cold air from the entrance hall 11 and the staircase room 41 hardly reaches the moving area 12a. Therefore, the risk of occurrence of the above-described heat shock can be reduced.

[0042] As shown in FIG. 1, in the building 100A of the present embodiment, a first non-residential room, the first-floor corridor 12, which is continuous with the entrance 11 and the staircase room 41, is connected to be accessible to the living and dining room 16 as a residential room, and the first-floor toilet 13 and the washroom 14 as second non-residential rooms, respectively, but is not limited to this configuration.

[0043] The first non-residential room only needs to be continuous with at least one of the entrance 11 and the staircase room 41, and does not necessarily need to be continuous with both the entrance 11 and the staircase room 41 like the first-floor corridor 12 of the present embodiment. Further, the first non-residential room is not limited to a corridor which is a space for movement. Furthermore, the floor on which the first non-residential room is provided is not limited to the first floor. Therefore, the first non-residential room may be a non-residential room other than a corridor on a floor different from the first floor.

[0044] The residential room connected to be accessible to the first non-residential room only needs to be configured to be accessible to the first non-residential room on the same floor, and is not limited to the living and dining room 16 of the present embodiment, and may be other residential rooms.

[0045] The second non-residential room connected to be accessible to the first non-residential room only needs to be configured to be accessible to the first non-residential room on the same floor and not to be continuous with the entrance 11 and the staircase room 41, and is not limited to the first-floor toilet 13 and the washroom 14 of the present embodiment, and may be other non-residential rooms.

[0046] Also, as shown in FIG. 3, in the building 100B of the present embodiment, in the first-floor corridor 12 as the first non-residential room, a moving area 12a located on the moving line from the living and dining room 16 as the residential room to the first-floor toilet 13 or the washroom 14 as the second non-residential room, and the remaining area 12b other than the moving area 12a, which is continuous with the entrance 11 and the staircase room 41 in the first-floor corridor 12, are partitioned by providing an opening / closing door 2, but is not limited to such a renovation method.

[0047] The door 2 as a shutter only needs to be able to partition at least the movement area 12a in the first-floor corridor 12 from the entrance hall 11 and the staircase room 41. The door 2 may be installed, for example, at a position partitioning between the first-floor corridor 12 and at least one of the entrance hall 11 and the staircase room 41. That is, the door 2 may be installed at a position between the area 12b shown in FIG. 3 and at least one of the entrance hall 11 and the staircase room 41. Further, in the present embodiment, the door 2 is installed as a shutter, but it may be a shutter of another form, such as a sliding door.

[0048] The structure, forming material, etc. of the shutter partitioning between the movement area 12a and the entrance hall 11 or the like are not particularly limited, but it is preferably a structure with high heat insulation and is composed of a forming material with high heat insulation.

[0049] As shown in FIG. 3, on the first floor of the building 100B, the movement area 12a of the first-floor corridor 12 as the first non-residential room and the living / dining room 16 as a residential room are continuous. That is, as shown in FIGS. 1 and 3, in the renovation method of the building 100 of the present embodiment, the movement area 12a of the first-floor corridor 12 and the living / dining room 16 are made continuous. Specifically, in the building 100B shown in FIG. 3, the door 51a as a shutter provided at the entrance 51 of the partition wall 81 shown in FIG. 1 has been removed. As a result, the movement area 12a of the first-floor corridor 12 and the living / dining room 16 can be constantly communicated through the entrance 51. Therefore, in winter, the warm air in the living / dining room 16 can be constantly spread to the movement area 12a through the entrance 51. As a result, the temperature difference between the living / dining room 16 and the movement area 12a of the first-floor corridor 12 is reduced, and the risk of occurrence of the heat shock described above can be further reduced.

[0050] Note that the method of making the movement area 12a of the first-floor corridor 12 and the living / dining room 16 continuous is not particularly limited. In the present embodiment, only the door 51a is removed, but for example, it may be made continuous by newly forming an opening in the partition wall. Note that, without performing such renovation, the risk of occurrence of the above heat shock may be reduced by keeping the door 51a open at all times.

[0051] Furthermore, as shown in FIG. 3, in Building 100B, the outer wall 85 that partitions the first-floor toilet 13 has been thermally insulated and renovated (refer to the thick line portion of the outer wall 85 in FIG. 3). That is, as shown in FIGS. 1 and 3, in the renovation method of Building 100 of the present embodiment, the outer wall 85 that partitions the first-floor toilet 13 as the second non-residential room is thermally insulated and renovated. "Thermal insulation renovation of the outer wall" means renovation to improve the thermal insulation performance, such as adding a heat insulating material, replacing it with a heat insulating material with high thermal insulation performance, or improving the thermal insulation performance of the window. As a result, the thermal insulation performance of the outer wall 85 that partitions the first-floor toilet 13 is improved, the inflow of cold air and the outflow of warm air are reduced, the temperature difference between the moving area 12a in the first-floor corridor 12 and the first-floor toilet 13 can be reduced, and the risk of heat shock that may occur during movement between the moving area 12a in the first-floor corridor 12 and the first-floor toilet 13 can also be reduced.

[0052] Also, as shown in FIG. 3, the outer wall 86 that partitions the washroom 14 has also been thermally insulated and renovated (refer to the thick line portion of the outer wall 86 in FIG. 3). That is, as shown in FIGS. 1 and 3, in the renovation method of Building 100 of the present embodiment, the outer wall 86 that partitions the washroom 14 as the second non-residential room is thermally insulated and renovated. As a result, the thermal insulation performance of the outer wall 86 that partitions the washroom 14 is improved, the inflow of cold air and the outflow of warm air are reduced, the temperature difference between the moving area 12a in the first-floor corridor 12 and the washroom 14 can be reduced, and the risk of heat shock that may occur during movement between the moving area 12a in the first-floor corridor 12 and the washroom 14 can also be reduced.

[0053] In this way, the outer walls 85 and 86 that partition the first-floor toilet 13 and the washroom 14, which are the second non-residential rooms that are connected to be accessible from the moving area 12a of the first-floor corridor 12 as the first non-residential room, are thermally insulated and renovated. As a result, the temperature drop of the first-floor toilet 13 and the washroom 14 due to the outside air is suppressed, the temperature difference between the moving area 12a and each of the first-floor toilet 13 and the washroom 14 can be reduced, and the risk of heat shock that may occur during mutual movement can be reduced.

[0054] Furthermore, in the building 100 of the present embodiment, not only the first-floor toilet 13 and washroom 14 described above, but also the bathroom 15 is a non-residential room that can be accessed from the living-dining room 16 only through the movement area 12a of the first-floor corridor 12. In the building 100 of the present embodiment, the first-floor toilet 13, washroom 14, and bathroom 15 are arranged in series as a group of non-residential rooms that can be accessed from the living-dining room 16 only through the movement area 12a of the first-floor corridor 12. Specifically, the first-floor toilet 13 and washroom 14, which are the second non-residential rooms that can be directly accessed from the movement area 12a of the first-floor corridor 12, are connected in series with the bathroom 15 sandwiched therebetween. The space between the first-floor toilet 13 and the bathroom 15 is partitioned by a partition wall 87. No openings such as entrances and exits are formed in this partition wall 87, and they cannot access each other. The space between the washroom 14 and the bathroom 15 is partitioned by a partition wall 88. An entrance 55 provided with a folding door 55a as a door is formed in this partition wall 88, and the washroom 14 and the bathroom 15 can access each other through this entrance 55.

[0055] More specifically, the first-floor toilet 13 in the building 100B is partitioned from the surroundings by a partition wall 87 between the bathroom 15 described above, the outer wall 85 described above, a partition wall 83 between the movement area 12a, and a partition wall 90 between the bedroom 19 described later. As described above, an entrance 53 that enables access between the first-floor toilet 13 and the movement area 12a and is provided with a door 53a as a door is formed in the partition wall 83 between the first-floor toilet 13 and the movement area 12a. Also, no openings such as entrances and exits are formed in the partition wall 90 between the first-floor toilet 13 and the bedroom 19.

[0056] In addition, the washroom 14 in the building 100B is partitioned from the surroundings by a partition wall 88 between the washroom 14 and the above-described bathroom 15, the above-described outer wall 86, a partition wall 84 between the moving area 12a, and a partition wall 91 between the storage space 41b of the staircase room 41. An entrance 54 enabling passage between the washroom 14 and the moving area 12a is formed in the partition wall 84 between the washroom 14 and the moving area 12a, and a sliding door 54a is provided as a door. Further, no opening such as an entrance is formed in the partition wall 91 between the washroom 14 and the storage space 41b of the staircase room 41.

[0057] Furthermore, the bathroom 15 in the building 100B is partitioned from the surroundings by a partition wall 87 between the bathroom 15 and the above-described first-floor toilet 13, a partition wall 88 between the bathroom 15 and the above-described washroom 14, and an outer wall 92 between the bathroom 15 and the outdoor space, which forms a protruding corner over two sides.

[0058] As shown in FIGS. 1 and 3, in plan view, the outer wall 85 partitioning the first-floor toilet 13 of the present embodiment from the outdoor space is linearly continuous with a part constituting one side surface (the left side surface in FIGS. 1 and 3) of the outer wall 92 partitioning the bathroom 15 from the outdoor space. Hereinafter, the outer wall 85 partitioning the first-floor toilet 13 from the outdoor space and the part constituting one side surface of the outer wall 92 partitioning the bathroom 15 from the outdoor space are collectively referred to as "one outer wall 201".

[0059] Also, as shown in FIGS. 1 and 3, in plan view, the outer wall 86 partitioning the washroom 14 of the present embodiment from the outdoor space is linearly continuous with a part constituting the other side surface (the upper side surface in FIGS. 1 and 3) of the outer wall 92 partitioning the bathroom 15 from the outdoor space. Hereinafter, the outer wall 86 partitioning the washroom 14 from the outdoor space and the part constituting the other side surface of the outer wall 92 partitioning the bathroom 15 from the outdoor space are collectively referred to as "the other outer wall 202".

[0060] As described above, the non-residential room group composed of the first-floor toilet 13, washroom 14, and bathroom 15 in this embodiment is partitioned from the outdoor space by the above-mentioned one outer wall 201 and the other outer wall 202 that form the corner of the building 100. And in this embodiment, the one outer wall 201 and the other outer wall 202 have been thermally renovated. Therefore, it is possible to suppress the temperature drop due to the outside air of the entire non-residential room group composed of the first-floor toilet 13, washroom 14, and bathroom 15. As a result, the temperature difference between the entire non-residential room group composed of the first-floor toilet 13, washroom 14, and bathroom 15 and the movement area 12a can be reduced, and the risk of heat shock that may occur during the movement between the entire non-residential room group and the movement area 12a can be reduced.

[0061] Also, as shown in FIG. 3, the non-residential room group composed of the first-floor toilet 13, washroom 14, and bathroom 15 in this embodiment is partitioned from the movement area 12a partitioned by the door 2 from the entrance 11 and the like by partition walls 83 and 84 that partition between the one outer wall 201 and the other outer wall 202 that have been thermally renovated and have improved heat insulation performance compared to the surrounding outer walls. In addition, it is partitioned from the surrounding by a partition wall 90 between the bedroom 19, which will be described later, and a partition wall 91 between the storage space 41b of the staircase room 41. The bedroom 19 is a residential room and a space that can be heated. Also, in this embodiment, the partition wall 91 between the non-residential room group composed of the first-floor toilet 13, washroom 14, and bathroom 15 and the storage space 41b of the staircase room 41 has also been thermally renovated (refer to the thick line part of the partition wall 91 in FIG. 3).

[0062] That is, the non-residential room group composed of the first-floor toilet 13, washroom 14, and bathroom 15 in this embodiment is partitioned from the surroundings by the heat-insulated outer walls (one outer wall 201 and the other outer wall 202 in this embodiment), the heat-insulated partition wall (partition wall 91 in this embodiment), the non-heat-insulated partition wall (partition wall 90 in this embodiment) between it and another living room (bedroom 19 in this embodiment), and the partition walls (partition walls 83 and 84 in this embodiment) between it and the movement area 12a where the cold air from the entrance 11 etc. is blocked by the door 2. In other words, the non-residential room group in this embodiment is not partitioned from the surroundings by non-heat-insulated partition walls between non-residential rooms, except for the outer walls that have not been heat-insulated and the partition walls between it and the movement area 12a. Therefore, it is possible to suppress the temperature of the non-residential room group composed of the first-floor toilet 13, washroom 14, and bathroom 15 from decreasing due to the influence of the surrounding outdoor space and non-residential rooms. As a result, the temperature difference between the non-residential room group and the movement area 12a can be made smaller, and the risk of heat shock that may occur during movement between the entire non-residential room group and the movement area 12a can be further reduced.

[0063] Conventionally, for heat insulation renovation to improve the heat insulation performance of a building, even if only a part of the outer wall of the building is renovated, the effect is small, and it has generally been common to renovate the outer walls of the entire building. On the other hand, various renovations of buildings are often carried out partially, and corridors, entrances, etc. often do not have equipment, etc., so they are often not renovated. In contrast, the heat insulation renovation of the outer walls of the building 100 in this embodiment may be only the renovation of a part of the outer walls (one outer wall 201 and the other outer wall 202) that partition the non-residential room group composed of the first-floor toilet 13, washroom 14, and bathroom 15 from the outdoor space. Thereby, the risk of heat shock that may occur during movement between the entire non-residential room group and the movement area 12a can be reduced. In this embodiment, the heat insulation performance of the one outer wall 201 and the other outer wall 202 is higher than that of the surrounding outer walls (for example, the non-heat-insulated outer wall 93 that partitions between the bedroom 19 and the outdoor space in this embodiment). The comparison of the heat insulation performance may be determined by, for example, the presence or absence of heat insulation renovation, but it is desirable to measure the temperature of the outer surface and the inner surface of the outer wall under the same conditions without sunlight, and determine that the one with the larger difference has higher heat insulation performance.

[0064] However, the heat insulation renovation of the outer wall of the building 100 may not be limited to only a part of the outer walls (in this embodiment, one outer wall 201 and the other outer wall 202) that partition the non-residential room group composed of the first-floor toilet 13, washroom 14, and bathroom 15 from the outdoor space. The heat insulation renovation of the one outer wall 201 may be performed up to the outer wall 93 that partitions between the bedroom 19 and the outdoor space and is linearly continuous with the one outer wall 201 in plan view. Similarly, the heat insulation renovation of the other outer wall 202 may be performed up to the outer wall 94 that partitions between the staircase room 41 and the outdoor space and is linearly continuous with the other outer wall 202 in plan view.

[0065] Also, although the heat insulation renovation of the one outer wall 201 and the other outer wall 202 in this embodiment is performed from the indoor side of the first-floor toilet 13, washroom 14, and bathroom 15, it is not limited to this configuration. The heat insulation renovation of the one outer wall 201 and the other outer wall 202 may be performed, for example, from the outdoor side of the first-floor toilet 13, washroom 14, and bathroom 15.

[0066] In addition, when performing the heat insulation renovation of the one outer wall 201 from the outdoor side, the heat insulation renovation of the one outer wall 201 may be performed up to the outer wall 93 that partitions between the bedroom 19 and the outdoor space and is linearly continuous with the one outer wall 201 in plan view. By doing so, it is possible to suppress the remaining of the trace of the boundary (such as a step) between the heat-insulated part and the non-heat-insulated part at a prominent position on the outdoor side surface of the outer wall of the building 100. For the case of performing the heat insulation renovation of the other outer wall 202 from the outdoor side, for the same reason as above, it may also be performed up to the outer wall 94 that partitions between the staircase room 41 and the outdoor space and is linearly continuous with the other outer wall 202 in plan view.

[0067] Also, as shown in FIGS. 1 and 3, the guest room 18 as a living room in Building 100A has been converted into a bedroom 19 as a living room in Building 100B. That is, in Building 100A, the bedroom 35 was provided on the second floor, which is different from the first floor where the first-floor corridor 12, living / dining room 16, first-floor toilet 13, washroom 14, and bathroom 15 are provided. Therefore, it was necessary to move from the first floor to the second floor at bedtime. On the other hand, in Building 100B, the guest room 18 (see FIG. 1) as another living room connected to the living / dining room 16 has been converted into a bedroom 19 (see FIG. 3). Therefore, the occupant does not have to move to another floor at bedtime.

[0068] In particular, in Building 100B, the bedroom 19 is arranged so as to be accessible from the living / dining room 16 through the movement area 12a of the first-floor corridor 12. In other words, the bedroom 19 in Building 100B of the present embodiment can be accessed from the living / dining room 16 without passing through the space continuous with the entrance 11 or the staircase room 41. Therefore, the generation of heat shock associated with the movement between the living / dining room 16 and the bedroom 19 can be suppressed. As shown in FIG. 3, it is preferable to maintain the entrance 56 provided with the sliding door 56a as a door in the building 100A (see FIG. 1) before renovation. By doing so, the bedroom 19 is directly connected to the living / dining room 16 through the entrance 56. However, it is not limited to such renovation. The entrance 56 provided with the sliding door 56a as a door may be removed with the conversion of the guest room 18 to the bedroom 19.

[0069] Also, in the present embodiment, the guest room 18 that was connected to the living / dining room 16 so as to be accessible has been converted into a bedroom 19, but it is not limited to this. For example, a part of the living / dining room 16 may be converted into a bedroom. Also, the living room before being converted into the bedroom 19 does not have to be the guest room 18. Also, the living room before being converted into the bedroom 19 may be connected to a living room other than the living / dining room 16. The living room before being converted into the bedroom 19 may be connected to, for example, any of the living room, dining room, kitchen, dining kitchen, and living / dining / kitchen.

[0070] In this embodiment, for the sake of convenience of explanation, as an example of the first non-living room, the first-floor corridor 12, as an example of the living room that is communicably connected to the first non-living room, the living-dining room 16, and as an example of the second non-living room that is communicably connected to the first non-living room, the first-floor toilet 13 and washroom 14 have been exemplarily described. However, as described above, the first non-living room, the living room that is communicably connected to the first non-living room, and the second non-living room that is communicably connected to the first non-living room are not limited to these. Therefore, the relationships among the above-described first-floor corridor 12, living-dining room 16, and first-floor toilet 13 (or washroom 14) may be realized in non-living rooms and living rooms for other purposes. Even in such a case, as described above, the effect of reducing the risk of heat shock can be obtained.

[0071] Also, in this embodiment, only the outer wall on the first floor of the building 100 has been thermally insulated and renovated. However, for example, in addition to the outer wall, it is preferable to thermally insulate and renovate at least one of the floor and ceiling portions of the first-floor toilet 13, washroom 14, and bathroom 15, and it is more preferable to thermally insulate and renovate both. By doing so, the above-described risk of heat shock can be further reduced. Note that regarding the thermal insulation renovation of the floor and ceiling portions of the first-floor toilet 13, washroom 14, and bathroom 15, for example, the renovation method is not particularly limited as long as it is a renovation that enhances the thermal insulation performance, such as adding a heat insulating material or replacing it with a heat insulating material having high thermal insulation performance.

[0072] The renovation method and building according to the present invention are not limited to the specific methods and configurations shown in the above-described embodiments, and various changes, modifications, and combinations are possible without departing from the scope of the claims.
