Description

The present invention achieves both (1) development of effective use of existing homes and (2) promotion of renovation that contributes to energy saving of existing homes, which is a major problem in the current housing environment. It provides technology related to an epoch-making model house that can be achieved with an unprecedented point of view.

In recent years, energy saving has been discussed worldwide on environmental issues, and performance evaluation from the viewpoint of energy saving has been emphasized for general houses as well. That is, in general houses, a lot of energy is consumed to maintain the temperature and humidity in the room in order to realize a comfortable living environment, so the importance of housing performance such as heat insulation is socially recognized. ..

However, it was not until the middle and late Heisei era that standards were set for housing performance, which has a large effect on indoor temperature, and the system began to be put into practical use. Therefore, the actual situation is that the heat insulation performance and airtightness performance of existing old general houses are significantly inferior. In particular, based on the Act on Promotion of Housing Quality Assurance, which came into effect on April 1, 2000, evaluation criteria that also cover energy conservation are given, and a housing performance display system by a third-party organization. Before the start of the construction, the heat insulation performance of ordinary houses was neglected, and the heat insulation performance was significantly inferior to that of the current new houses.

Therefore, even under the government policy to promote the distribution of general housing (buying and selling of used housing), the value of used housing built before the end of March 2000 is extremely low, and no objective evaluation result is given. Therefore, there is a problem that the demand is scarce, it is difficult to distribute it, and it is difficult to even find an effective utility value. In short, there was a problem that effective usage of old existing houses was not cultivated (Problem A).

On the other hand, housing performance such as heat insulation performance is improving year by year due to changes in public awareness such as energy saving and technological improvements, especially the energy consumption of buildings that took effect on April 1, 2016. After strengthening the obligation to report energy conservation plans based on the Act on Improvement of Performance, significant improvement in housing performance has been achieved. Therefore, even if the house was built after April 2000, the living environment and energy saving will be improved by improving the performance such as heat insulation by remodeling the used house whose performance such as heat insulation is not sufficient. Renovation to achieve this is also recommended as a government policy.

However, the renovation of an existing house for the purpose of improving performance such as heat insulation requires major renovation including material changes such as walls and floors and replacement of fittings such as sashes, unlike simple remodeling, and the required cost. Also bulky. In recent years, many types of walls, floors, sashes, etc. with different materials have been provided, and it is becoming difficult to select them. In particular, the realization of high-level energy saving entails an increase in costs, so the reality is that the owner does not want to improve the energy-saving performance unnecessarily. The result is to hurt. If it is a new house, it may be possible to experience it by visiting a model house of a major manufacturer, but how much living environment can be experienced in a renovation that changes only a part of an existing existing house, for example, a specific room. There was a problem that it was difficult to actually experience whether an improvement effect could be obtained, which made it even more difficult to make a selection decision (Problem B).

By the way, the "problem A" and the "problem B" pointed out regarding the existing existing housing as described above are recognized as problems of different viewpoints and different events that are not related to each other.

It is proposed in Japanese Patent Application Laid-Open No. 2020-60704 to set up an experience room having different specifications in a newly constructed model house, but the dimension is different from that of the present invention in that problem.

Japanese Unexamined Patent Publication No. 2020-60704

The problem to be solved by the present invention against the background of such circumstances is to solve the "problem A" and "problem B" pointed out regarding the existing existing housing as described above from a characteristic point of view that has not been seen in the past. It is an object of the present invention to provide an invention that can bring about a breakthrough and social benefit by solving or improving it in relation to each other.

In particular, the present invention is intended to improve such social problems related to the environment, and an application for the "Business Restructuring Promotion Project" proposed by the Ministry of Economy, Trade and Industry (Small and Medium Enterprise Agency) for the purpose of promoting new businesses is submitted. After that, it is related to the business that the applicant plans to carry out. It is a socially significant invention with a new perspective that fulfills the purpose of a national project by the Ministry of Economy, Trade and Industry.

Hereinafter, preferred embodiments for grasping the present invention will be described, but each of the embodiments described below is described as an example, and not only can be appropriately combined with each other and adopted, but also described in each embodiment. The plurality of components of the above can be recognized and adopted independently as much as possible, and can be appropriately adopted in combination with any of the components described in another embodiment. Thereby, in the present invention, various other embodiments can be realized without being limited to the embodiments described below.

The first aspect consists of a renovated building of an existing existing house, and has a shared space in which outside air is introduced and placed in an environment equivalent to the outside air, and the shared space is partitioned by a wall. A plurality of experience rooms are provided independently of each other, and the plurality of experience rooms have different construction conditions of at least one of a floor material, a wall material, a heat insulating material, and an airtight structure, and the plurality of experience rooms are different from each other. Each room is a renovation model house equipped with an air conditioner.

According to the renovation model house according to this aspect, for example, a visitor who is thinking of renovation can enter the experience room from a shared space such as a front door exposed to harsh outside air by visiting in the summer or winter. Therefore, the difference in temperature and humidity from the outside air can be felt more on the skin. Here, for example, by making the operating conditions of the air conditioner the same, the temperature and humidity of each experience room will be different from each other according to the construction conditions of each experience room. As a result, the visitor can feel the difference in temperature and humidity caused by the difference in construction conditions, and for example, by considering it together with the cost associated with the construction, the visitor can renovate himself / herself. In some cases, it is possible to determine how much renovation is appropriate.

In particular, since the renovation model house according to this aspect consists of a renovated existing existing house, it is possible to secure a construction site and design a new building compared to the case of building a model house equipped with such an experience room from scratch. ， Troublesome procedures such as building permission application can be unnecessary or simplified, and in general, by renovating only each room of a used house, it is possible to establish a model house equipped with a hands-on room at a much more efficient and low cost. It will be possible. In addition, not only can we reduce building materials and costs when manufacturing model houses, but we can also effectively use used houses for which we could not find effective utility value, and a large amount of industrial waste associated with the dismantling of used houses. It is also possible to suppress the generation of things and it is excellent for the global environment. In addition, for example, in a second-hand house, by not intentionally renovating the shared space such as the entrance, the shared space can be made stable and easily in an environment equivalent to the outside air, and the effect of renovation can be experienced more efficiently. It is also possible to do.

The second aspect is that in the renovation model house according to the first aspect, the used house is a building before March 2000.

According to this aspect, such a pre-owned house can be effectively used for a building before March 2000, for which an effective value has hardly been found in the past. In addition, because it is a second-hand house where heat insulation and airtightness are not emphasized, the difference in temperature and humidity between the shared space placed in an environment equivalent to the outside air and the experience room after renovation is even more noticeable. You can feel it with.

The third aspect is the shared space inside the wall in which the outside air is introduced into the partition wall between the adjacent experience rooms among the plurality of experience rooms in the renovation model house according to the first or second aspect. Is provided.

According to this aspect, heat transfer or the like through a partition wall between adjacent experience rooms is suppressed, and the difference in each experience room can be more efficiently grasped as an effect due to the difference in construction conditions. Even when a shared space inside the wall is provided as in this embodiment, it is preferable that a heat insulating layer as in the fourth aspect described later is used in combination.

A fourth aspect is that in the renovation model house according to any one of the first to third aspects, a heat insulating layer is provided on the partition wall between the adjacent experience rooms among the plurality of experience rooms. It is something that is.

A fifth aspect is that in the renovation model house according to any one of the first to fourth aspects, upper and lower shared spaces into which outside air is introduced are provided above and below the ceiling of the plurality of experience rooms. It is a thing.

According to this aspect, it is possible to suppress the influence between the experience rooms having different levels, and to more accurately grasp the difference in each experience room as an effect due to the construction conditions. The upper and lower shared spaces in this embodiment may be used in combination with the heat insulating layer in the sixth aspect described later.

A sixth aspect is that in the renovation model house according to any one of the first to fifth aspects, heat insulating layers are provided on the ceiling and under the floor of the plurality of experience rooms.

In general houses, it is not necessary to install a heat insulating layer on the ceiling on the first floor or under the floor on the second floor, and in many cases it is not installed. It is preferable to install it under the floor.

A seventh aspect is that in the renovation model house according to any one of the first to sixth aspects, at least two of the experience rooms are provided with an outer wall having a window, and each of the experience rooms is provided with an outer wall. The performance of the windows is different.

The eighth aspect is that in the renovation model house according to any one of the first to seventh aspects, one of the experience rooms is a base room in which the construction conditions of the used house are maintained.

According to this aspect, by using the base room as a control, it becomes possible to make better use of the existing house and make the visitor experience it more easily. In addition, the effect of the renovation can be experienced not only in the shared space but also in comparison with the base room.

The ninth aspect is the renovation model house according to the eighth aspect, in which the opening / closing portion for the entrance / exit of each experience room other than the base room has a heat insulating structure and an airtight structure.

According to this aspect, heat transfer or the like is suppressed through the opening / closing portion for the entrance / exit of each experience room, and it is possible to more accurately sense the temperature change or the like due to the difference in construction conditions.

A tenth aspect is the renovation model house according to any one of the first to ninth aspects, which is a two-story or three-story building, and a plurality of the experience rooms are provided in each of a plurality of floor areas. It is something that is.

According to this aspect, since the experience room is provided in each of the plurality of hierarchical areas, it is possible to feel the difference in temperature and humidity between the upper floor and the lower floor, for example, and the temperature due to the difference in the hierarchical area can be felt. Visitors can also determine the construction conditions for their renovation, taking into account changes in humidity.

The eleventh aspect is the renovation model house according to the tenth aspect, in which each one of the plurality of experience rooms provided in each of the plurality of floor areas remains the construction conditions of the used house. It is said to be the base room.

For example, the basic environmental conditions in a house differ greatly between the first floor and the second floor due to the effects of geothermal heat, solar heat, and temperature distribution. Therefore, according to this aspect, by providing a standard control for each floor, visitors can experience it more easily, and the difference in the experience room can be changed in the construction conditions without considering the influence of the difference in the hierarchical area. As a result, it can be grasped more accurately.

A twelfth aspect is the renovation model house according to any one of the first to eleventh aspects, wherein a thermometer is provided in each of the plurality of experience rooms, and the temperature in the plurality of experience rooms is measured. A temperature change display showing a change over time is provided.

According to this aspect, for example, the difference in temperature changes in each experience room when the conditions are equivalent to each other is displayed so as to be suitable for comparison, thereby objectively presenting the difference in performance. Will be possible. Specifically, for example, when heating is turned on in each experience room for a certain period of time in the morning in winter, how the room temperature rises due to heating and how the room temperature drops after the heating is stopped are compared and presented among multiple experience rooms. It is also possible to make it. In addition, for example, it is conceivable to compare and present how the temperature of each experience room rises when the outer wall receives the sunlight in the daytime in the summer. Further, for example, temperature changes during daytime, nighttime, sunny weather, rainy weather, before and after the operation of the air conditioner, etc. can be grasped even if the visitor is not in the experience room. In addition, other environmental factors such as humidity can also be displayed.

A thirteenth aspect is the renovation model house according to any one of the first to twelfth aspects, wherein the air conditioner is separately provided in each of the plurality of experience rooms, and the target of each experience room is An air conditioner operation status display indicating the operation status of each air conditioner installed in each experience room under the same temperature setting is provided.

According to this aspect, the effect of the renovation can be grasped by observing the difference in the operating status of each air conditioner as a result of making the target temperature setting the same instead of making the operating conditions of the air conditioner the same. .. For example, the operating status of the air conditioner can be indicated by power consumption, energy consumption, an air volume change mode when an automatic air volume is set, and the like. In this aspect, when realizing the same in-house environment, for example, in the experience room with high heat insulation performance, the operating rate of the air conditioner is suppressed as compared with the experience room with low heat insulation performance, and the utility cost is also reduced. It is also possible to objectively show that it can be suppressed.

The fourteenth aspect is a construction example display unit for displaying the housing performance value and the construction cost for the plurality of experience rooms in the renovation model house according to any one of the first to thirteenth aspects. It has.

According to this aspect, the visitor can easily grasp the cost-effectiveness in the renovation by checking the construction example display unit at the time of visiting the renovation model house. In particular, visitors can not only subjectively sense the temperature and humidity with their skin, but also grasp the housing performance value and construction cost, which can be a great reference for their own renovation.

At the same time, the shared space inside the wall provided on the partition wall between the adjacent experience rooms among the plurality of experience rooms to introduce the outside air, and the outside air provided above the ceiling and under the floor of the plurality of experience rooms. The upper and lower shared spaces to be introduced are provided , and the shared space in the wall and the upper and lower shared spaces are connected to the shared space in communication with each other.

According to this aspect, since the outside air is positively introduced into the shared space, the shared space inside the wall and the upper and lower shared spaces communicating with the shared space by the ventilation fan, the shared space can be more easily placed in an environment equivalent to the outside air. In addition to being able to be placed in the wall, it is possible to more effectively prevent the influence of heat transfer or the like between the experience rooms on both sides of the shared space inside the wall or the upper and lower shared spaces.

In the sixteenth aspect, in addition to a shared space in which outside air is introduced and placed in an environment equivalent to the outside air, a plurality of experience rooms partitioned by a wall portion are provided for the existing existing house. By providing the plurality of experience rooms independently of each other and making at least one construction condition of the floor material, the wall material, and the heat insulating material different from each other, and providing an air conditioner in each of the plurality of experience rooms. It is a method of manufacturing a model house for constructing the experience-based renovation model house according to any one of the first to fifteenth aspects.

According to this aspect, it is possible to construct a renovation model house capable of exerting the effect according to any one of the first to fifteenth aspects.

A seventeenth aspect is the method for manufacturing a model house according to the sixteenth aspect, wherein at least a part of the outer wall portion of the shared space and the communication area to the shared space is applied to the existing existing house. The heat insulating material is removed or reduced.

According to this aspect, by reducing or removing, for example, glass wool or foam panel, which has been previously installed as a heat insulating material on the outer wall portion of the shared space or the like, the shared space or the like can be made closer to the outside air environment. As a result, for example, it becomes possible to easily reduce the influence on the shared space environment by air conditioning of each experience room, or the environment of each experience room under the severe environment in the shared space in midwinter or midsummer is further enhanced. It will also be possible for people to experience it in an easy-to-understand manner.

In the eighteenth aspect, the visitor is sequentially guided to the plurality of experience rooms having different construction conditions by using the experience-type renovation model house described in any one of the first to fifteenth aspects. In order to experience the difference in the living space environment for each construction condition, the air conditioner is used to air-condition each of the plurality of experience rooms under the same conditions in advance of the same amount of time before guiding the visitor to the plurality of experience rooms. In a renovation model house where you can experience the environmental difference in the living space between the experience rooms by guiding the visitor to each experience room in the situation where the same time has passed since the end of the air conditioning. It is an operation method.

According to this aspect, for example, the air conditioning of a plurality of experience rooms is simultaneously turned on for a predetermined time in the morning in the winter, and then the air conditioning is stopped. Visitors who wish to experience the experience will be guided to each experience room at noon or afternoon after a predetermined time has passed since the stoppage. Also, for example, in the summer, similarly, the air conditioning of multiple experience rooms should be applied to the air conditioners for a predetermined time at the same time, and then the air conditioning should be stopped. It becomes. As a result, even if the same energy for air conditioning (cooling and heating costs) is applied, it is possible to directly compare and experience how much difference in living environment will occur depending on the construction conditions. It will be possible.

In the nineteenth aspect, the experience-type renovation model house described in any one of the first to fifteenth aspects is used to sequentially guide visitors to the plurality of experience rooms having different construction conditions. In presenting the difference between the experience rooms, the air conditioner realizes the same temperature environment for each of the experience rooms by the same amount of time before guiding the visitor to the plurality of experience rooms. The air conditioner is continuously executed so as to guide the visitor to each of the plurality of experience rooms, and the operation status of each air conditioner over time is shown for each experience room. This is an operation method of a renovation model house that objectively presents the difference in energy-saving performance between the experience rooms.

According to this aspect, for example, by setting the target temperature in the air conditioner to be the same, the operating conditions of the air conditioner in each experience room are different from each other according to the construction conditions of each experience room. By sequentially guiding the visitor to the experience room and showing the operation status of the air conditioner in each experience room, the visitor can grasp the difference in the operation status of the air conditioner in each experience room as the difference in the construction conditions. You can use it as a reference for your own renovation.

Multiple experience rooms with different construction conditions for those who are going to renovate their homes because they can effectively use existing homes that could not find effective value in the past (solving "Problem A"). By having them experience this, we can provide one of the materials to judge how much renovation is appropriate from the viewpoint of cost effectiveness etc. (solving "problem B") Renovation model house , Can be provided efficiently.

It is preferable that the windows 30 are provided in at least two of the experience rooms 14 (first to fifth experience rooms 14a to 14e) in order to compare windows having different performances. In each of the experience rooms 14 (first to fifth experience rooms 14a to 14e), at least one window 30 (first to fifth windows 30a to 30e) is provided.

Some of these experience rooms 14 (1st to 5th experience rooms 14a to 14e) have been renovated (renovated) from the state of the used house 10', and specifically, the flooring material. At least one construction condition of the wall material, the heat insulating material, and the airtight structure is different. These flooring materials, wall materials, heat insulating materials, and airtight structures are not limited, and conventionally known materials, materials, construction structures, etc. can be adopted. Specific examples of materials and materials that can be used as a structure.

Examples of the floor material include plywood flooring using wood, solid flooring, tiles, bricks, cork, tile carpets, tatami mats and the like. The wood used for plywood flooring and solid flooring is not limited to cherry, cedar, 桧, oak, pine, red pine, walnut, black cherry, maple, chestnut, teak, Conventionally known woods such as tamo (ash), birch (kabazakura), rosewood, and bamboo can be adopted in consideration of discrimination such as plate thickness. Further, the method of pasting the wood is not limited, and conventionally known pasting methods such as standard-sized pasting, random pasting (random-scale pasting), diagonal pasting, and herringbone pasting can be adopted. Even if the same plywood flooring or solid flooring is used, if the wood and board thickness used are different, the construction conditions will be different because it will affect the heat insulation, etc., and the appearance, feel, construction cost, etc. will also be different. It is grasped as a thing. Similarly, even when the same wood is used, it can be understood that the construction conditions are different because the appearance, the construction cost, and the like are different when the pasting method is different. Further, soundproofing materials, cushioning materials, heat insulating panels and the like may be appropriately used in combination with these flooring materials.

The wall material is a partition wall 22 that separates each experience room 14, a wall portion that separates each experience room 14 from the first and second floor corridors 16 and 20, and a wall portion that separates the first floor 11 and the second floor 13. It is used for 22'(for example, the ceiling) and constitutes the peripheral wall of each experience room 14. The structure of these walls is not limited, but for example, the inner surface (inside of the room) of the gypsum board is finished. Examples of finishing include conventionally known materials such as cloth (vinyl cloth, cloth cloth, paper cloth, etc.), plaster walls (diatomaceous earth, plaster, clay walls, etc.), tiles, wood (solid wood, plywood, etc.), panels, etc. And materials can be adopted. A soundproofing material, a cushioning material, or the like may be used in combination with these wall materials as appropriate. Further, the wall material in each experience room 14 not only constitutes the inner wall of each experience room 14, but may also constitute an outer wall in addition to the inner wall. That is, it is understood that the construction conditions are different because the materials and materials used for finishing are different for the inner wall of each experience room 14, for example, the thickness of the gypsum board, the number of layers, and the outer surface side of the gypsum board. It can be understood that the construction conditions are different by differentiating the structure, material, material, etc. of the outer wall to be provided.

The heat insulating material is provided, for example, by inserting a board-shaped or sheet-shaped heat insulating material between pillars or the like, or by blowing and filling a liquid heat insulating material to appropriately foam it, and the walls and floors of each experience room 14 are provided. In addition to being provided on the ceiling or the like, it can also be used as the heat insulating layer 24 provided in the partition wall 22 described above. Examples of the heat insulating material include glass wool, rock wool, cellulose fiber, wool (wool breath), carbonized cork, polystyrene foam (bead method polystyrene foam, extruded polystyrene foam), rigid urethane foam, phenol foam and the like. Further, the rigid urethane foam and various closed-cell foam materials may be in-situ foamed urethane that is foamed and then cured in the field, or may be factory foamed urethane that is foamed and then cured and shipped at the factory. .. As described above, the heat insulating material is filled inside, for example, the wall portion, but may be provided on the roof or on the outer surface of the outer wall in addition to the inside of the wall portion.

In each experience room 14, at least two of the floor material, the wall material, and the heat insulating material may be combined to make the structure of each experience room 14 different. For example, the difference in the structure of the inner wall is the presence or absence of glass wool, which is a heat insulating material, and the difference in the amount (density), the presence or absence of a heat insulating panel and the difference in its thickness, the presence or absence of foamed heat insulating material, and the presence or absence of gypsum board. Differences in the number of sheets, differences in structural materials such as steel frames and wood, etc. can be mentioned. Then, as the surface material of the inner wall, cloth, board, plaster wall, panel, ceramic tile, brick, stone and the like are combined. Similarly, as a difference in the floor structure of each experience room 14, the difference in the above-mentioned heat insulating material and plasterboard can be adopted in combination with the above-mentioned various floor materials, and as a difference in the ceiling structure, the above-mentioned heat insulating material. It can be adopted in combination with the difference between plasterboard and the above-mentioned various wall materials constituting the ceiling.

Further, windows having different performances are, for example, windows having different types of windows, sashes, windowpanes, and the like. Conventionally known types of windows, sashes, window glasses, etc. are used, but the types of windows include, for example, sliding windows, vertical sliding windows, horizontal sliding windows, FIX windows, and sash windows. , Louver windows, etc. The types of sashes include aluminum sashes, aluminum resin composite sashes, resin sashes, wooden sashes, etc., and the types of window glass include general glass and double glazing (heat-shielding double glazing, highly heat-insulated double glazing). Layered glass), laminated glass, vacuum glass, etc.

As described above, the construction conditions for the renovations in the first to fifth experience rooms 14a to 14e are different, so that the construction costs in the first to fifth experience rooms 14a to 14e are different. In the present embodiment, the fourth experience room 14d on the second floor 13 is a base room which is a construction condition of the used house 10'. Therefore, the construction cost of the fourth experience room 14d (base room) is substantially 0 yen (see the construction example display unit 32 of FIG. 5 described later).

In addition, each experience room 14 is provided with an opening / closing portion α for an entrance / exit to the shared space. The opening / closing portion α is at least prevented from natural convection of air with the common space, and is composed of a door or a door that can be closed except when a person enters or exits. The opening / closing portion α may have different specifications for each experience room 14 so as to correspond to the specifications (construction conditions) of each experience room 14, but the opening / closing portion α is indispensable as a model room. , There is no problem even if it is a common specification, and by doing so, it is possible to experience the difference between the experience rooms 14. At that time, it is desirable that the door (sliding door or door) constituting the opening / closing portion α has both airtightness and heat insulating properties. In particular, it is preferable to provide an opening / closing portion α having both airtightness and heat insulating properties in each experience room 14 excluding the base room. Specifically, for example, sashes and doors with both heat insulation and airtightness that are marketed for entrances and sweep-out windows can be adopted to satisfy the requirements of current highly airtight houses. .. It is also possible to add a gap seal, a heat insulating material inside the door, etc. as needed to construct the opening / closing part α.

Further, in the present embodiment, each experience room 14a to 14e is provided with a construction example display unit 32 that displays the housing performance value and the construction cost so that they can be compared with each other. Here, examples of the housing performance value displayed on the construction example display unit 32 include a Ua value (average thermal transmission rate of the outer skin), a Q value (heat loss coefficient), a C value (equivalent gap area), and the like. In addition, the construction example display unit 32 displays, for example, construction conditions for floors, walls, heat insulating materials, windows, etc., seismic strength scores (superstructure scores), room temperature at predetermined times in summer and winter, construction costs, and the like. May be good. FIG. 5 shows a specific example of the construction example display unit 32. A visitor of the renovation model house 10 can grasp the cost-effectiveness in the renovation by checking the construction example display unit 32 in each of the experience rooms 14a to 14e. Such a construction example display unit 32 may be arranged at a place that is easily noticed on the visitor's tour route, such as near the entrance of each experience room 14a to 14e or an internal wall. As shown in FIG. 5, the construction example display unit 32 arranges, for example, a shared space or each of the experience rooms 14a to 14e so that information about each experience room 14a to 14e can be compared at once. Alternatively, only the information about the experience rooms 14a to 14e to be arranged may be displayed. In addition to the above information, the construction example display unit 32 may display, for example, the size and orientation of each experience room 14a to 14e, the maximum and minimum temperature in the room in summer and winter, and the average temperature.

It is also possible to install a device for acquiring a thermography in each experience room 14 and display the acquired thermograph. The construction example display unit 32 and the thermograph can display not only the current one but also the past one, for example, information acquired over time throughout the day or one year.

The airtightness of each experience room 14 can be measured by, for example, a commercially available house airtightness test device. Specifically, it is possible to adopt the C value measured by using an airtightness measuring instrument "KNS-5000C" manufactured by Corner Sapporo Co., Ltd.

Further, each of the experience rooms 14a to 14e is provided with an air conditioner 34 as an air conditioner, and the temperature of each experience room 14a to 14e can be adjusted. Each air conditioner may be individually operable, or may be a centralized cooling device or heating device that collectively adjusts the room temperature of each experience room 14a to 14e. The air conditioner does not have to have both cooling and heating functions, and may have only one of the functions. Further, the air conditioner may be a heater or a stove in place of or in addition to the air conditioner 34, and may have a humidity control function for humidifying or dehumidifying in place of or in addition to the temperature control function. May be good. The air conditioners 34 installed in the experience rooms 14a to 14e may be the same type of air conditioner, or the performance may be different depending on the size and the like of the experience rooms 14a to 14e.

In the present embodiment, the thermometer 36 is provided in each of the experience rooms 14a to 14e. Further, each of the experience rooms 14a to 14e is provided with a temperature change display 38 indicating a change with time of the temperature by the thermometer 36. The thermometer 36 and the temperature change display 38 are provided at positions that are easily visible to the visitor, such as the walls of the experience rooms 14a to 14e. The temperature change display 38 records, for example, the room temperature of each of the experience rooms 14a to 14e measured by the thermometer 36 at regular time intervals (for example, 30 minutes or 1 hour) to record the change in room temperature. It may be displayed as a graph or a table. The thermometer 36 and the temperature change display 38 may be, for example, constantly operated, and the temperature change display 38 may be reset, for example, every 24 hours, or the guide of the renovation model house 10 (for example,). The renovation company's sales staff, etc.) may be able to operate it directly or remotely prior to the visitor's visit, or it may be automatically turned on and off by setting a timer, etc. good.

Alternatively, each experience room 14a to 14e may be provided with an air conditioning operation status display 40 indicating the operation status of each air conditioner 34 under the condition that the target temperature setting of the air conditioner 34 is the same. The air-conditioning operation status display 40 is designed to record how many minutes the air-conditioner 34 has been operated, for example, at regular time intervals (for example, 30 minutes or 1 hour), and displays changes in the operating status in a graph or table. It may be. The air conditioner 34 and the air conditioner operation status display 40 may be always operated, for example, or may be operated by the guide of the renovation model house 10 prior to the visitor's visit, or a timer may be set. It may be turned on and off automatically by such means. Further, the air conditioning operation status display 40 may display not only the operating time of the air conditioner 34 but also the electricity bill generated by the operation of the air conditioner 34.

Alternatively, in each of the experience rooms 14a to 14e, both the temperature change display 38 and the air conditioning operation status display 40 are provided so that the guide can explain to the visitor by showing either one. good.

Hereinafter, a specific example of the method of manufacturing the model house for constructing the renovation model house 10 of the present embodiment will be described, but the method of manufacturing (building) the renovation model house 10 is not limited.

First, prepare an existing used house 10'. The used house 10'preferably is, for example, a building before March 2000. This is because the heat insulation and airtightness of buildings before March 2000 are not so important, it is difficult to find an effective usage method, and it is easier to realize the effect of renovation. The entrance 12, the corridor 16 on the first floor, the stairs 18, and the corridor 20 on the second floor will not be renovated and will be a shared space where outside air is introduced and placed in an environment equivalent to the outside air.

On the other hand, the room originally in the second-hand house 10'is partitioned by a wall portion from the shared space, renovated as necessary, and the first to fifth experience rooms 14a to 14e are provided independently of each other. Depending on the arrangement of the rooms in the second-hand house, the partition between the adjacent rooms may be eliminated to form one large room, or the wall portion located between the upper and lower floors may be eliminated to form a blown-out structure. Further, a heat insulating layer 24 and / or an in-wall shared space 26 is provided on the partition wall 22 between the adjacent experience rooms 14, and a heat insulating layer 24 and / or an upper and lower shared space 27 is provided on the ceiling and under the floor of the experience room 14. When the shared space 26 in the wall and / or the shared space 27 above and below is provided, the outer wall portion of the area communicating with the shared space and the shared space (shared space 26 in the wall and the shared space 27 above and below) in the used house 10'. Remove or reduce the insulation provided in at least part of the space.

In the present embodiment, the fourth experience room 14d on the second floor 13 is a base room that is not renovated. On the other hand, the first experience room 14a on the first floor 11 has been renovated to the current general newly built housing specifications (general housing specifications), and the second and third experience rooms 14b and 14c on the first floor 11 have been renovated. The fifth experience room 14e on the second floor 13 will be renovated to have high heat insulation and high airtightness.

For example, in the 4th experience room 14d, which is the base room, and the 1st experience room 14a, which is a general residential specification, the floor material is plywood flooring, the wall and ceiling materials are vinyl cloth, and the heat insulating material is glass wool. Has been done. The material of the plywood flooring and vinyl cloth may be different between the 4th experience room 14d (base room) and the 1st experience room 14a (general housing specification), but even if they are the same, the floor material and By reattaching the materials for the walls and ceiling, re-arranging the heat insulating material, and increasing the amount (density) of the heat insulating material, the heat insulating property and airtightness of the first experience room 14a are compared with those of the fourth experience room 14d. Sex is improved.

On the other hand, the 2nd, 3rd and 5th experience rooms 14b, 14c, 14e, which have high heat insulation and high airtightness, use solid wood, cedar, and red pine as the floor material, and diatomaceous earth as the material for the walls and ceiling. In addition to using plaster walls, urethane foam on site is used as a heat insulating material. As a result, the second, third and fifth experience rooms 14b, 14c, 14e, which are more heat-insulated and airtight than the first and fourth experience rooms 14a and 14d, are provided. In particular, in the present embodiment, the grades of the second, third and fifth experience rooms 14b, 14c and 14e, which have the same high heat insulation and high airtightness specifications, are different, and the fifth experience room 14e and the second experience room 14e have different grades. The room 14b and the third experience room 14c are made to have higher heat insulation and higher airtightness in this order, and the construction cost is improved by that amount (see the construction example display unit 32 in FIG. 5).

After that, an air conditioner 34, which is an air conditioner, is provided in each of the experience rooms 14a to 14e, and a thermometer 36, a temperature change display 38, and an air conditioner operation status display 40 are provided as needed. In addition, each experience of the construction example display unit 32, which calculates the housing performance values (for example, Ua value, Q value, C value) of each experience room 14a to 14e according to a predetermined procedure and makes it possible to compare with the construction cost. It will be installed in rooms 14a to 14e. Then, if necessary, for example, a ventilation fan 28 may be provided on the ceiling of the corridor 16 on the first floor, the ceiling of the corridor 20 on the second floor, the outer wall defining the shared space, or the shared space and / or each experience room 14a to 14e. By providing a fan or the like, the renovation model house 10 of the present embodiment is completed.

Hereinafter, a specific example of the operation method of the renovation model house 10 of the present embodiment will be described, but the operation method of the renovation model house 10 is not limited.

First, prior to the visitor's visit, the guide operates the air conditioner 34, the thermometer 36, and the temperature change display 38 as needed. If the air conditioner 34, the thermometer 36, and the temperature change display 38 are always in operation, this operation is not performed. When operating the air conditioner 34, the air conditioners 34 in the experience rooms 14a to 14e are operated so that the set temperature, the air volume, the wind speed, and the like are substantially the same. When the air conditioners 34 of the experience rooms 14a to 14e are centrally managed, these conditions are considered to be substantially the same. When the humidity can be set in addition to the temperature, it is preferable that the set humidity of each of the experience rooms 14a to 14e is substantially the same. The set temperature of the air conditioner 34 is not limited, but is set to, for example, about 22 degrees. However, the set temperature may be different between summer and winter. By the way, the room temperature of each experience room 14a to 14e at 2:00 pm in midsummer (early August) and 8:00 am in midwinter (early February) is displayed in the construction example display section of FIG. 5, which is an air conditioner. It is the room temperature when a predetermined time (for example, 3 hours or 5 hours) has elapsed after the operation of 34 is stopped.

After operating the air conditioner 34 for a predetermined time (for example, 3 hours or 5 hours) (cooling in summer, heating in winter), the operation of the air conditioner 34 is stopped, and then the operation of the air conditioner 34 is stopped for a predetermined time (for example, 3 hours or 5 hours). ) After that, the guide guides the visitor to the renovation model house 10. In other words, for example, if a visitor plans to visit the renovation model house 10 in the afternoon, for example, the air conditioner 34 is operated at 8 am or 9 am on the day, or the visitor visits the renovation model house 10 in the morning. In the case of a schedule, for example, the air conditioner 34 may be operated at 9 pm or 10 pm the day before.

The guide guides the visitor from the entrance 12 to the first to third experience rooms 14a to 14c via the corridor 16 on the first floor, and then goes up to the second floor through the stairs 18, and the fourth and fifth experience rooms. We will guide you to 14d and 14e in sequence. In each experience room 14a to 14e, the guide shows the thermometer 36 and the temperature change display 38 to the visitor, and the second, third, and fifth experience rooms 14b rather than the first and fourth experience rooms 14a and 14d. , 14c, 14e will be explained as having higher heat insulation and higher airtightness. Then, among them, the fifth experience room 14e, the second experience room 14b, and the third experience room 14c will be described in that order of higher heat insulation and higher airtightness. In that case, for example, the temperature change display 38 is shown to explain that the room temperature is difficult to rise in the summer and that the room temperature is difficult to fall in the winter. In addition, the guide shows the construction example display unit 32 to the visitor in each of the experience rooms 14a to 14e, and explains the cost-effectiveness that this level of cost is required for this level of renovation. ..

Alternatively, prior to the visitor's visit, the guide operates the air conditioner 34, the thermometer 36, and the air conditioning operation status display 40, if necessary. When operating the air conditioner 34, the air conditioners 34 in the experience rooms 14a to 14e are operated so that the set temperature, the air volume, the wind speed, and the like are substantially the same. When the humidity can be set in addition to the temperature, it is preferable that the set humidity of each of the experience rooms 14a to 14e is substantially the same.

After a predetermined time (for example, 3 hours or 5 hours) has elapsed, the guide guides the visitor to the renovation model house 10 under the operating condition of the air conditioner 34. After sequentially guiding from the entrance 12 to the first to third experience rooms 14a to 14c via the corridor 16 on the first floor, the user goes up to the second floor through the stairs 18 and sequentially guides to the fourth and fifth experience rooms 14d and 14e. In each experience room 14a to 14e, the guide shows the thermometer 36 and the air conditioning operation status display 40 to the visitor, and the second, third, and fifth experience rooms are more than the first and fourth experience rooms 14a and 14d. Explain that 14b, 14c, 14e have higher heat insulation and higher airtightness. Then, among them, the fifth experience room 14e, the second experience room 14b, and the third experience room 14c will be described in that order of higher heat insulation and higher airtightness. In that case, for example, the air-conditioning operation status display 40 is shown, and in the highly heat-insulated and highly airtight experience room 14, the operating time of the air-conditioner 34 is short, and the difference in energy-saving performance is objectively explained. In addition, the guide shows the construction example display unit 32 to the visitor in each of the experience rooms 14a to 14e, and explains the cost-effectiveness that this level of cost is required for this level of renovation. ..

As described above, the temperature change display 38 and the air conditioning operation status display 40 may be adopted in combination, and the experience room 14 (for example, the first to third experience rooms 14a to described by the temperature change display 38) may be adopted. In 14c), the visitor is guided by the guide after the elapse of a predetermined time after the air conditioner 34 is stopped, and the experience room 14 (for example, the fourth and fifth experience rooms 14d, 14e) explained by the air conditioning operation status display 40 is provided. ), The visitor may be guided by the guide under the operating condition of the air conditioner 34.

In the renovation model house 10 of the present embodiment having the above structure, the visitor is guided to a plurality of experience rooms 14a to 14e having different construction conditions, so that the temperature and humidity change due to the difference in construction conditions. Can be felt on the skin. In particular, since the shared space before entering each experience room 14a to 14e is in an environment equivalent to the outside air, the change in temperature and humidity and the effectiveness of renovation in each experience room 14a to 14e should be felt more strongly. Can be done. As a result, the visitor can recognize the effectiveness of the renovation and consider it together with the cost, which can be used as a reference when performing the renovation.

Further, the renovation model house 10 of the present embodiment is based on the used house 10', and the model house is not built from scratch, but only the necessary rooms are renovated. As a result, not only the cost can be reduced, but also the used house 10'for which an effective usage method has not been found can be effectively utilized.

In particular, when the used house 10'is a building before March 2000, the heat insulating property and the airtightness are not considered so much, and it is hard to say that the value as a used house is so high. Therefore, a more effective usage method could not be found, but it is more effective in terms of recognizing the effectiveness of the improvement of heat insulation and airtightness by renovation because the heat insulation and airtightness are not considered. , Old used houses can be used more effectively.

In the renovation model house 10 of the present embodiment, the partition wall 22 between the adjacent experience rooms 14 and 14 is provided with a shared space 26 in the wall into which outside air is introduced and a heat insulating layer 24. Further, an upper and lower shared space 27 and a heat insulating layer 24 for introducing outside air are provided on the ceiling and under the floor of the experience room 14. As a result, heat transfer between the adjacent experience rooms 14 and 14 on the same floor and between the adjacent experience rooms 14 and 14 on the upper and lower floors is prevented, and the temperature difference between the experience rooms 14 is different due to the difference in construction conditions. Can be recognized more accurately.

As the difference in the construction conditions, in addition to making at least one of the floor material, the wall material, the heat insulating material, and the airtight structure different, the difference in the performance of the window is also adopted. By recognizing (experiencing) the difference in window performance, visitors can use it as a reference for their own renovation.

Further, in the present embodiment, of the first to fifth experience rooms 14a to 14e, the fourth experience room 14d on the second floor 13 is regarded as a base room in which the construction conditions of the used house 10'are maintained. Therefore, by comparing the renovated experience room 14 (1st, 2nd, 3rd, 5th experience rooms 14a, 14b, 14c, 14e) with the base room, the effectiveness of the renovation can be further realized. be able to.

Further, the renovation model house 10 of the present embodiment is a two-story building, and a plurality of experience rooms 14 are provided on both the first floor 11 and the second floor 13. As a result, by experiencing the experience rooms 14 on different floors, it is possible to experience not only the construction conditions but also how the difference in the floors affects the changes in temperature and humidity, and the same floors can experience each other. By experiencing the plurality of experience rooms 14, the difference in temperature and humidity in each experience room 14 can be recognized as a difference in construction conditions without considering the difference in hierarchy.

Further, the difference in temperature in each experience room 14 can be objectively grasped by the thermometer 36. Then, it is possible to show the change in room temperature in each experience room 14 as the temperature change display 38, and it is also possible to more accurately grasp the effect of the renovation.

Alternatively, an air conditioner operation status display 40 indicating the operation status of the air conditioner 34 is provided under the condition that the target temperature setting of the air conditioner (air conditioner 34) of each experience room 14 is the same, whereby the effect of the renovation can be objectively obtained. You can also figure it out.

Further, it is preferable that each experience room 14 is provided with a construction example display unit 32 that displays the housing performance value and the construction cost so that they can be compared with each other. This allows the visitor to have a more accurate picture of the cost-effectiveness of the renovation. As the housing performance value, not only the Ua value, the Q value, and the C value but also the temperature change display 38 and the air conditioning operation status display 40 may be shown.

Further, in the above embodiment, the base room (fourth experience room 14d) is provided only on the second floor 13, but for example, the base room may be provided on the first floor, for example, in addition to the fourth experience room 14d. The second experience room 14b may be used as the base room. As a result, the difference in temperature and humidity in each experience room 14 can be recognized as a difference in construction conditions without considering the difference in floor.

The temperature change display 38 displays the temperature change over time in the experience room 14, in addition to or instead of the one performed for each experience room, so that the display of different experience rooms or the experience rooms to be compared can be directly compared. It may be displayed side by side. Similarly, the display of the operating status of the air conditioner (air conditioner 34) in the experience room 14 by the air conditioning operation status display 40 is performed in addition to or instead of the one performed for each experience room. The displays may be displayed side by side so that they can be directly compared.

It is desirable that at least two experience rooms to be compared have conditions other than the construction conditions to be compared, such as the floor and the orientation of the room, the orientation and size of the windows, and the size of the room as much as possible.
