Description

  The present invention relates to a thermal insulation design support system that targets a predesigned building and supports thermal insulation design for the target building.

  In recent years, a building excellent in heat insulation performance is required from the viewpoint of energy saving and the like. Also, along with that, a thermal insulation design support system that supports thermal insulation design of a building has been proposed in part (see, for example, Patent Document 1).

  Examples of this type of system include a calculation system that calculates the heat insulation performance of the building based on the design data (CAD data) of the building and the heat insulation specification of the building set by the designer. For example, there is a system that calculates an average skin heat transfer coefficient (UA value) and a heat loss coefficient (Q value), which are indices indicating the heat insulation performance of a building.

  In the above calculation system, when the calculated thermal insulation performance of the building does not reach the target thermal insulation performance, the thermal insulation specification of the building is reset, and the thermal insulation performance of the building is calculated again based on the reset thermal insulation specification. It is considered to be Then, it is considered that the heat insulation specification is repeatedly set again until the calculated heat insulation performance of the building reaches the target heat insulation performance. That is, in this case, it is considered that the heat insulation specification which can obtain the target heat insulation performance will be sought while repeatedly setting the heat insulation specification.

Unexamined-Japanese-Patent No. 2003-193585

  In the calculation system described above, when the designer sets the heat insulation specification of the building, it is considered that the designer sets the heat insulation specification with some intuition. In particular, when setting the heat insulation specification first (initially setting), it is thought that relying on intuition becomes large, so when the heat insulation specification is initially set, the heat insulation performance calculated based on the heat insulation specification is the target It is conceivable that the heat insulation performance may be greatly reduced. In that case, it may be necessary to repeat many resetting of the insulation specification until the insulation performance of the building reaches the target insulation performance. Therefore, there is a possibility that the number of man-hours may be increased when obtaining the heat insulation specification capable of obtaining the target heat insulation performance.

  The present invention has been made in view of the above circumstances, and it is a main object of the present invention to provide a heat insulation design support system capable of reducing man-hours when obtaining a heat insulation specification capable of obtaining a target heat insulation performance for a building. It is

  In order to solve the above problems, the thermal insulation design support system of the first invention is a thermal insulation design support system that targets thermal insulation design of a target building for a predesigned building, and the design of the target building Design data acquisition means for acquiring data, heat insulation specification setting means for setting heat insulation specification of the target building, design data of the target building acquired by the design data acquisition means, and setting by the heat insulation specification setting means Heat insulation performance calculation means for calculating the heat insulation performance of the target building based on the heat insulation specification of the target building, and the target heat insulation for which the heat insulation performance of the target building calculated by the heat insulation performance calculation means is predetermined. And a target determination unit that determines whether or not the performance has been reached, and the heat insulation work to initialize the heat insulation specification of the target building as the heat insulation specification setting means. When the heat insulation performance of the target building calculated by the initial setting means and the heat insulation performance calculation means has not reached the target heat insulation performance, the heat insulation specification of the target building is re-determined The heat insulation specification resetting means to set, the heat insulation specification initial setting means, construction area acquisition means for acquiring information of the construction area where the target building is constructed, the number of floors of the target building and the roof shape Of the target building based on the construction area of the target building acquired by the construction area acquiring unit and the building condition of the target building acquired by the building condition acquiring unit. It is characterized in that the heat insulation specification is initialized.

  According to the present invention, the thermal insulation performance of the target building is calculated based on the acquired design data of the target building and the set thermal insulation specification of the target building, and the calculated thermal insulation performance reaches the target thermal insulation performance. It is determined whether the Then, when the target heat insulation performance is not reached, the heat insulation specification of the target building is reset, and the heat insulation performance of the target building is calculated again based on the reset heat insulation specification. In this case, the insulation specification of the target building is repeatedly set (re-set) until the calculated insulation performance of the target building reaches the target insulation performance.

  When the heat insulation specification of a target building is set, the case where the heat insulation specification of a target building is initially set (initial setting) and the case where it is reset are included. Then, in the present invention, when the heat insulation specification of the target building is initialized, the construction area of the target building and the building conditions (specifically, the number of floors and the roof shape) are acquired, and the acquired construction area and building conditions In accordance with, the insulation specification of the target building is initially set. Both the construction area of the building and the building conditions (the number of floors and the shape of the roof) are considered to be factors that greatly affect the heat insulation performance of the building. In this case, the heat insulation specification of the target building can be initialized based on the construction area of the target building and the building conditions, whereby the insulation specification of the target building can be initialized. As a result, it is possible to avoid that the thermal insulation performance of the target building calculated based on the initially set thermal insulation specification falls far below the target thermal insulation performance, so the thermal insulation performance of the target building reaches the target thermal insulation performance. It is possible to reduce the number of re-setting of the adiabatic specification which is repeated repeatedly. Therefore, in this case, the number of man-hours can be reduced when obtaining the heat insulation specification that can obtain the target heat insulation performance.

  In the heat insulation design support system according to a second aspect of the present invention, in the first aspect, the heat insulation specification initial setting means sets a part heat insulation specification for each heat insulation function part predetermined as a part involved in heat insulation performance in the target building. By doing this, the heat insulation specification of the target building is initialized, and for a predetermined heat insulation function area among the heat insulation function areas, a site suitable for the combination of the construction area in the building and the building condition The database includes the database for storing the heat insulation specification as the reference part heat insulation specification, and the heat insulation specification initial setting means, for the predetermined heat insulation function part of the target building, includes the construction area of the target building acquired by the construction area acquisition means The reference part heat insulation specification corresponding to the combination with the building condition of the target building acquired by the building condition acquiring means Obtained from serial database, and sets the reference part insulation specifications acquired As part insulation specifications of the predetermined Insulated site.

  According to the present invention, the heat insulation specification of the target building is initialized by setting the part heat insulation specification for each of the heat insulation function parts of the target building. Then, at the time of this initial setting, a region heat insulation specification is set using a database for a predetermined heat insulation function region among the heat insulation function regions of the target building. In this case, for the predetermined heat insulation function part, it becomes possible to set the part heat insulation specification suitable for the construction area of the target building and the building conditions using the above database, and as a result, the construction area of the target building And it becomes possible to initialize the insulation specification suitable for building conditions. This makes it possible to specifically realize the first aspect of the invention.

  In the heat insulation design support system according to the third invention, in the first or second invention, the heat insulation specification initializing unit is a heat insulation area for each of the heat insulation function areas predetermined as the area involved in the heat insulation performance in the target building. By setting the specifications, the heat insulation specification of the target building is initialized, and multiple heat insulation specification candidates having different heat insulation effects are prepared in advance for each of the heat insulation function parts, and the heat insulation specification resetting means The heat insulation function is higher than the heat insulation specification set for the heat insulation function area among the plurality of area heat insulation specification candidates for any one of the heat insulation function areas of the heat insulation function areas of the target building There is a part heat insulation specification reset means for resetting specification candidates as a part heat insulation specification of the heat insulation function part, and the target construction is based on the resetting by the part heat insulation specification reset means. Characterized in that it re-set the thermal insulation specification.

  According to the present invention, for any one of the heat insulation functional parts of the target building, the area heat insulation specification candidate having a higher heat insulation effect than the part heat insulation specification set for the part is a new area heat insulation specification By being reset, the insulation specification of the target building is reset. In this case, at the time of resetting the heat insulation specification of the target building, the heat insulation performance is enhanced only at any one of the heat insulation functional sites among the heat insulation functional sites of the target building. For this reason, it is possible to increase the thermal insulation performance of the target building little by little by resetting the thermal insulation specification, and as a result, the thermal insulation performance of the target building greatly exceeds the target thermal insulation performance by resetting the thermal insulation specification ( It is possible to avoid the occurrence of so-called excessive specifications.

  In the heat insulation design support system of the fourth invention according to the third invention, a first heat insulation function area and a second heat insulation function area different from the first heat insulation function area are provided as the heat insulation function area; First heat insulation specification resetting means for resetting the heat insulation specification of the target building based on resetting of the part heat insulation specification of the first heat insulation function part by the part heat insulation specification resetting means as heat insulation specification reset means And second heat insulation specification resetting means for resetting the heat insulation specification of the target building based on resetting of the area heat insulation specification of the second heat insulation function area by the area heat insulation specification resetting means; The heat insulation specification by the heat insulation specification resetting means until the target judgment means judges that the heat insulation performance of the target building calculated by the heat insulation performance calculation means has reached the target heat insulation performance Resetting is repeated, and in the repetition, among the resetting of the heat insulation specification by the first heat insulation specification resetting means and the resetting of the heat insulation specification by the second heat insulation specification resetting means, Resetting by the first adiabatic specification resetting means is performed with priority, and resetting by the first adiabatic specification resetting means is the most adiabatic effect among the plurality of site heat insulation specification candidates for the first adiabatic function site. The above-mentioned priority is carried out until the high site heat insulation specification candidate is reset as the site heat insulation specification.

  According to the present invention, when the re-setting of the heat insulation specification of the target building is repeated, the re-setting of the part heat insulation specification is preferentially repeated for the same heat insulation functional part (first heat insulation functional part). In this case, when the resetting of the adiabatic specification is repeated, the adiabatic performance is gradually increased only at the same adiabatic function portion. For this reason, when the resetting of the heat insulation specification is repeated, it can be said that the configuration is preferable in order to gradually increase the heat insulation performance of the target building.

  The heat insulation design support system according to the fifth invention is the heat insulation design support system according to the fourth invention, wherein the area heat insulation specification candidate having the highest heat insulation effect is set as the area heat insulation specification for the first heat insulation function area. Of the resetting by the heat insulation specification resetting means and the resetting by the second heat insulation specification resetting means, the resetting by the second heat insulation specification resetting means is performed, and the second heat insulation The specification resetting means, at the time of resetting, the part heat insulation specification having a lower heat insulation effect than the part heat insulation specification set in the first heat insulation functional part among the plurality of part heat insulation specification candidates for the first heat insulation functional part The candidate is re-set as the part heat insulation specification of the first heat insulation function part, and after the re-setting by the second heat insulation specification re-setting means, the re-setting by the first heat insulation specification re-setting means is prioritized Characterized in that it is.

  According to the present invention, by repeatedly resetting the part heat insulation specification for the same heat insulation function part (first heat insulation function part), the part heat insulation specification (part heat insulation specification candidate) having the highest heat insulation effect as the part heat insulation specification Is set, then the site heat insulation specification is reset for the heat insulation function site (second heat insulation function site) different from the heat insulation function site. Then, at the time of this resetting, at the same time, a part heat insulation specification candidate having a lower heat insulation effect than the part heat insulation specification set for the first heat insulation functional part is reset as a new part heat insulation specification. Then, after that, resetting of the part heat insulation specification (by the part heat insulation specification resetting means) is repeated again for the first heat insulation function part. In this case, when the heat insulation specification is repeatedly set, it is possible to further improve the heat insulation performance of the target building little by little.

  According to a sixth aspect of the present invention, in the heat insulation design support system according to any of the third to fifth aspects, the heat insulation function part includes an appearance affected part which is predetermined as a part that affects the appearance according to the part heat insulation specification. The heat insulation specification of the target building based on resetting the heat insulation specification of the heat insulation function area different from the appearance affected area by the area heat insulation specification reset means as the heat insulation specification reset means. The fourth adiabatic specification for resetting the adiabatic specification of the target building based on the third adiabatic specification resetting means to be reset and the adiabatic specification of the portion affected by the appearance by the partial adiabatic specification resetting means. Reset means, and the target determining means determines that the heat insulation performance of the target building calculated by the heat insulation performance calculation means has reached the target heat insulation performance. It has a repeating means which repeats resetting of the heat insulation specification of the target building by the heat insulation specification resetting means up to the third heat insulation specification resetting means in repeating the resetting by the heat insulation specification resetting means as the repeating means. In the first repeating means not including the resetting by the fourth adiabatic specification resetting means while including the resetting by the second heat re-setting by the third adiabatic specification resetting means for repeating the resetting by the adiabatic specification resetting means And second repeating means including at least resetting by the fourth adiabatic specification resetting means among setting and resetting by the fourth adiabatic specification resetting means, the target calculated by the thermal insulation performance calculating means When it is determined by the target determination unit that the thermal insulation performance of the building has reached the target thermal insulation performance, the above-mentioned setting at the time of the judgment The output means is provided with an output means for outputting the heat insulation specification of the elephant building, and the output means is a case where the heat insulation performance of the target building becomes the heat insulation performance of the target by repetition by the first repeating means, and by the second repeating means The heat insulation specification of the target building is output for each of the cases where the heat insulation performance of the target building becomes the target heat insulation performance by repetition.

  According to the present invention, the insulation specification of the target building is repeatedly reset until the calculated insulation performance of the target building reaches the target insulation performance, and when the target insulation performance is reached, it is set when the target is achieved. The heat insulation specifications of the target building are output to the display unit or the like. This enables the user to grasp the heat insulation specification of the target building that satisfies the target heat insulation performance.

  Here, as a method of repeating resetting of the adiabatic specification, the site adiabatic specification is reset (by the part adiabatic specification resetting means) only for the adiabatic functional part different from the appearance affected part among the respective adiabatic functional parts in the repetition Method (corresponding to the first repeating means) and the method (corresponding to the second repeating means) for resetting the part heat insulation specification (by the part heat insulation specification resetting means) for the heat insulation function part including at least the appearance affected part It is done. In this case, while the repetition of the resetting by the first repeating means does not affect the appearance of the building, the repetition of the resetting by the second repeating means affects the appearance of the building.

  And, in the present invention, when the heat insulation performance of the object building becomes the target heat insulation performance by repeating the resetting by the first repeating means, and the heat insulating performance of the object building is the target by repeating the resetting by the second repeating means. For each case of heat insulation performance, we will output the heat insulation specifications of the target building at the time of the goal achievement. In this case, since a plurality of heat insulation specifications having different building appearances are output, the user can determine the heat insulation specifications of the target building while considering the appearance of the target building.

  The heat insulation design support system according to a seventh aspect of the present invention is the heat insulation design support system according to the sixth aspect, wherein the heat insulation specification of the target building is initialized before the repetition by the first repeating unit is performed as the heat insulation specification setting unit. And a second heat insulation specification initialization means for initializing the heat insulation specification of the target building before the repetition by the second repetition means is performed, and the repetition by the first repetition means is performed by the first repetition means. The first heat insulation specification initial setting means is the heat insulation specification initial setting means, and the second heat insulation specification initial setting means is the repetition of the first heat insulation specification initial setting means. As a result, it is set in the target building at the time of the target achievement determination determined by the target determination means that the thermal insulation performance of the target building has reached the target thermal insulation performance. The insulation specifications have been set just before the insulation specification is characterized in that the initializing as insulation specifications of the target building.

  According to the present invention, the repetition of the resetting by the first repeating means is performed prior to the repetition of the resetting by the second repeating means, and is performed before the repetition by the second repeating means (second heat insulation specification initialization) In the initialization of the adiabatic specification by means, the result of the repetition by the first repetition means is used. Specifically, at the time of initial setting of the heat insulation specification, the insulation performance of the target building is set immediately before the heat insulation specification set for the target building when the target achieved the target heat insulation performance in the first repeating means. The thermal insulation specification is initially set as the thermal insulation specification of the target building. In this case, the initial setting of the heat insulation specification makes it possible to bring the heat insulation performance of the target building closer to the target heat insulation performance. Therefore, when the resetting of the heat insulation specification is repeated until the heat insulation performance of the target building reaches the target heat insulation performance in the second repeating means, the number of repetitions can be reduced, and the number of man-hours can be reduced.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the present embodiment, a heat insulation design support device that supports the heat insulation design of the building is embodied for the designed building. FIG. 1 is a diagram showing an electrical configuration of the heat insulation design support apparatus.

  As shown in FIG. 1, the heat insulation design support device 10 is provided to the building maker. The heat insulation design support device 10 is configured of a personal computer and has a CAD program for designing a building. The heat insulation design support apparatus 10 supports the heat insulation design of a building designed for a CAD program.

  The heat insulation design support device 10 includes a control unit 11, an operation unit 12, a display unit 13, and a storage unit 14. The control unit 11 is connected to the operation unit 12, the display unit 13, and the storage unit 14. The control unit 11 performs various processes such as a design process of a building and a heat insulation design support process for supporting the heat insulation design of the building.

  The operation unit 12 is for inputting various types of information such as information necessary to support building design and heat insulation design, and includes a keyboard, a mouse, and the like. When an input operation is performed on the operation unit 12, information corresponding to the input operation is input to the control unit 11.

  The display unit 13 displays various information related to the heat insulation design support process, and includes a display. When various information is input from the control unit 11 to the display unit 13, the input information is displayed on the display unit 13.

  The storage unit 14 stores a control program for executing the heat insulation design support process and a database for storing various information necessary for the process. The storage unit 14 also stores design data of a building designed using a CAD program.

  Next, the flow of the heat insulation design support process executed by the heat insulation design support device 10 will be described based on FIG. FIG. 2 is a functional block diagram showing the flow of thermal insulation design support processing. The blocks 21 to 25 in FIG. 2 are realized by the control unit 11.

  As shown in FIG. 2, the design data acquisition unit 21 reads out and acquires design data (CAD data) of a building stored in the storage unit 14. In the present embodiment, it is assumed that heat insulation design support is performed for this building, and this building is hereinafter referred to as a building X. The building X corresponds to the "target building". Further, the design data acquisition unit 21 corresponds to design data acquisition means.

  A schematic view of the building X is shown in FIG. As shown in FIG. 3, the building X is a two-story house, and the roof is a sloped roof (such as a new roof or a gable roof). The building X is provided with a casing site M1, a floor foundation site M2, a window site M3, and a door site M4 as the site of the outer skin (hereinafter referred to as the outer skin site M). All of these skin parts M1 to M4 correspond to the heat insulation functional parts that affect the heat insulation performance of the building X. The housing part M1 is a part including the wall, the roof and the ceiling of the building X. The floor foundation site M2 is a site including the floor portion and the foundation of the first floor portion of the building X. The window part M3 is a part including the window opening of the building X and the window sash provided in the window opening. The door portion M4 is a portion including the entrance of the building X and the entrance door provided at the entrance.

  The design data of the building X acquired by the design data acquisition unit 21 includes site data of each of the skin sites M1 to M4. The site data of the outer coat site M1 to M4 includes data indicating the area of the outer coat site M1 to M4, data indicating the size and arrangement of each component constituting the outer coat site M to M4, and data indicating the material of each component In addition, various data necessary for calculating the heat insulation performance of the building X are included.

  The heat insulation specification setting unit 22 sets the heat insulation specification of the building X by setting the part heat insulation specification (insulation specification of the skin part) for each of the skin parts M1 to M4 in the building X. Specifically, a plurality of site heat insulation specification candidates having different heat insulation effects are prepared in advance for each outer skin site M1 to M4, and in the heat insulation specification setting unit 22, a plurality of area heat insulation specification candidates for each outer skin site M1 to M4 One of them is set as the site insulation specification. The heat insulation specification setting unit 22 corresponds to heat insulation specification setting means.

  In FIG. 4, site heat insulation specification candidates for each of the skin sites M1 to M4 are shown. As shown in FIG. 4, there are standard heat insulation specifications and high heat insulation specifications as the area heat insulation specification candidates of the housing part M1. Both the standard thermal insulation specification and the high thermal insulation specification are specifications that provide insulation on the wall, roof and ceiling of the building. The high heat insulation specification is a specification in which a heat insulating material is added to the standard heat insulation specification, whereby the heat insulation effect is higher than that of the standard heat insulation specification. Specifically, the high thermal insulation specifications include specifications G1 to G4 of a plurality of types (specifically, four types) having different thermal insulation effects. In these high thermal insulation specifications G1 to G4, the thickness of the thermal insulation to be used, the installation location of the thermal insulation, and the like are different from each other. In each of the high thermal insulation specifications G1 to G4, the magnitude relationship of the thermal insulation effect is G1 <G2 <G3 <G4.

  The site heat insulation specification candidates of the floor foundation area M2 include a floor insulation specification and a base insulation specification. The floor insulation specification is a specification in which a heat insulating material is provided under the floor of the first floor portion of a building, and the base insulation specification is a specification in which a heat insulating material is provided on the side of a building foundation (peripheral foundation). The base insulation specification has a higher insulation effect than the floor insulation specification.

  There are a standard sash specification and a heat insulation sash specification as a part heat insulation specification candidate of the window part M3. The standard sash specification and the heat insulation sash specification are both heat insulation specifications for the sash. The heat insulation sash specification has a higher heat insulation effect than the standard sash specification.

  There are a door specification H1, a door specification H2, and a door specification H3 as the region heat insulation specification candidates for the door region M4. Each of these door specifications H1 to H3 is a heat insulation specification for the entrance door. In these door specifications H1 to H3, the thickness, the material, and the like of the entrance door are different from each other. Thereby, the magnitude relation of the heat insulation effect of each door specification H1 to H3 is H1 <H2 <H3. Moreover, in each door specification H1-H3, the external appearance of the entrance door is also mutually different. Therefore, in this case, the door portion M4 corresponds to an appearance affected portion that affects the appearance by the portion heat insulation specification.

  Returning to the description of FIG. 2, the heat insulation performance calculation unit 23 determines the building based on the design data of the building X acquired by the design data acquisition unit 21 and the heat insulation specification of the building X set by the heat insulation specification setting unit 22. Calculate the thermal insulation performance of X. In the present embodiment, the heat insulation performance calculation unit 23 calculates a skin average heat transmissivity UA value (hereinafter, simply referred to as a UA value) which is one of the heat insulation performance indexes indicating the heat insulation performance of the building X. The UA value is an index indicating that the smaller the value is, the higher the thermal insulation performance of the building is. The UA value is calculated using the following equation (1).

UA value = total amount of heat loss at each skin site Mi of building X / skin area of building X (1)
Here, the amount of heat loss of the outer skin site Mi can be obtained by calculating the product of the heat transmission coefficient Ui and the area Ai at the outer skin site Mi. In this case, the heat transmission coefficient Ui of the outer skin site Mi is obtained based on the site adiabatic specification set for the area Mi. For example, the storage unit 14 stores a database in which the heat transmission coefficient Ui is stored in association with each heat insulation specification of each skin portion Mi. And when calculating | requiring the heat transmission coefficient Ui, it calculates | requires by reading the heat transmission coefficient Ui corresponding to the site | part heat insulation specification of the outer_skin | epidermis site | part Mi from the database. In addition, the area Ai of the skin portion Mi is obtained based on the design data of the building X. Furthermore, the skin area of the building X is also determined based on the design data of the building X.

  In the heat insulation performance calculation unit 23, it is not necessary to calculate the UA value as the heat insulation performance of the building X, and another heat insulation performance index such as a heat loss coefficient (Q value) may be calculated. Moreover, the heat insulation performance calculation part 23 is corresponded to the heat insulation performance calculation means in this case.

  The target determination unit 24 determines whether the heat insulation performance of the building X calculated by the heat insulation performance calculation unit 23 has reached a predetermined target heat insulation performance. Specifically, the target determination unit 24 determines whether the UA value of the building X calculated by the heat insulation performance calculation unit 23 is equal to or less than a predetermined target value Uo. In the present embodiment, the target value Uo of the UA value is set to 0.6. Also, this target value Uo corresponds to the target thermal insulation performance. The target value Uo may be a fixed value or may be variably set based on an operation by the user. The target determination unit 24 corresponds to target determination means.

  The output unit 25 is calculated by the heat insulation performance calculation unit 23 when the target judgment unit 24 determines that the heat insulation performance of the building X calculated by the heat insulation performance calculation unit 23 has reached the target heat insulation performance. When it is determined that the UA value of the building X is equal to or less than the target value Uo, the heat insulation specification of the building X set at the time of the determination is output to the display unit 13. As a result, the display unit 13 displays the heat insulation specification of the building X satisfying the target heat insulation performance. The output unit 25 corresponds to an output unit.

  When it is determined by the target determination unit 24 that the heat insulation performance of the building X calculated by the heat insulation performance calculation unit 23 does not reach the target heat insulation performance, that is, the UA value of the building X calculated by the heat insulation performance calculation unit 23 When it is determined that the target value Uo exceeds the target value Uo, the adiabatic specification setting unit 22 resets the adiabatic specification of the building X. Then, the heat insulation performance calculation unit 23 recalculates the heat insulation performance of the building X based on the reset heat insulation specification of the building X and the design data of the building X acquired by the design data acquisition unit 21, The target determination unit 24 determines again whether the recalculated insulation performance of the building X is the target insulation performance.

  As described above, in the thermal insulation design support process, the thermal insulation specification setting unit 22 and the thermal insulation performance calculation unit until the target determination unit 24 determines that the calculated thermal insulation performance of the building X has reached the target thermal insulation performance. Each process is repeatedly performed in the target determination unit 24 and the target determination unit 24.

  Next, the heat insulation specification setting process by the heat insulation specification setting unit 22 will be described in detail.

  The heat insulation specification setting unit 22 includes a heat insulation specification initial setting unit 31 that performs initial setting (initial setting) of the heat insulation specification of the building X, and a heat insulation specification reset unit 32 that resets the heat insulation specification of the building X. The heat insulation specification reset unit 32 resets the heat insulation specification of the building X when the target judgment unit 24 determines that the heat insulation performance of the building X calculated by the heat insulation performance calculation unit 23 does not reach the target heat insulation performance. It is In the thermal insulation design support process, the thermal insulation specification of the building X is repeatedly reset in the thermal insulation specification resetting unit 32 until the thermal insulation performance of the building X reaches the target thermal insulation performance. The heat insulation specification initial setting unit 31 corresponds to the heat insulation specification initial setting means, and the heat insulation specification reset unit 32 corresponds to the heat insulation specification reset means.

  Subsequently, the heat insulation specification initial setting process by the heat insulation specification initial setting unit 31 will be described based on FIG. FIG. 5 is a functional block diagram showing the function of the heat insulation specification initial setting unit 31. As shown in FIG.

  As shown in FIG. 5, the heat insulation specification initial setting unit 31 has a building condition acquisition unit 34, a construction area acquisition unit 35, and a heat insulation specification database 36. The building condition acquisition unit 34 acquires the number of floors of the building X and the roof shape as the building condition of the building X based on the input operation of the operation unit 12 by the user. In this embodiment, the input operation is performed on the input screen displayed on the display unit 13. In the following, this point will be described with reference to FIG. FIG. 6 is a diagram showing an input screen. The building condition acquisition unit 34 corresponds to a building condition acquisition unit.

  As shown in FIG. 6, on the input screen C, an input unit 37 for inputting the number of floors of the building X and an input unit 38 for inputting a roof shape of the building X are provided. The input unit 37 has a selection field capable of selecting any one of “one-story house”, “second floor” and “third floor” as the number of floors of the building. When any of these selection fields is selected by the operation of the operation unit 12, the number of floors corresponding to the selected selection field is input to the input unit 37 as the number of floors of the building X. Then, the building condition acquisition unit 34 acquires the number of floors of the building X that has been input.

  The input unit 38 has a selection field capable of selecting one of “gradient roof” and “flat roof” as a roof shape of a building. When any of these selection fields is selected by the operation of the operation unit 12, a roof shape corresponding to the selected selection field is input to the input unit 38 as a roof shape of the building X. Then, the roof shape of the input building X is acquired by the building condition acquisition unit 34.

  The construction area acquisition unit 35 acquires information of a construction area (construction planned area) where the building X is to be constructed. The construction areas are divided into 1 area to 7 areas according to the next generation energy saving standard. The construction area acquisition unit 35 acquires which of the areas (one area to seven areas) the construction area of the building X is. The construction area acquisition unit 35 corresponds to a construction area acquisition unit.

  The construction area acquisition unit 35 acquires the construction area of the building X based on the input operation of the operation unit 12 by the user. In the present embodiment, the input operation is performed on the above input screen C, and this point will be described below. As shown in FIG. 6, on the input screen C, an input unit 39 for inputting a construction area of the building X is provided. The input unit 39 has a selection field capable of selecting one of “1 area”, “2 area”, and “7 area” as a building construction area. When any of these selection fields is selected by the operation of the operation unit 12, the construction area corresponding to the selected selection field is input to the input unit 39 as the construction area of the building X. Then, the construction area acquisition unit 35 acquires the input construction area of the building X.

  The adiabatic specification database 36 stores, for each of the casing site M1 and the floor foundation site M2, a reference site adiabatic specification serving as a reference as the site adiabatic specification. Hereinafter, the heat insulation specification database 36 will be described with reference to FIG. FIG. 7 is a table for explaining the heat insulation specification database 36. The heat insulation specification database 36 corresponds to a "database".

  As shown in FIG. 7, the heat insulation specification database 36 is suitable for the combination of the building condition (the number of floors and the roof shape) in the building and the construction area for each of the housing part M1 and the floor foundation part M2. The part heat insulation specification is stored as the reference part heat insulation specification. In FIG. 7, portions corresponding to the reference site heat insulation specification are shown in black. In the example of FIG. 7, in the case of a combination where the building condition is a flat (the number of floors) and the construction area is any of 4 to 7 areas (see the first row in the table of FIG. 7) The standard site insulation specification of is the standard insulation specification, and the standard site insulation specification of the floor base section M2 is the floor insulation specification. In addition, in this combination, both the case of a flat (the number of floors) and a slope roof (the shape of a roof) and the case of a flat (the number of floors) and the flat roof (the shape of a roof) are included about building conditions. In addition, in the case of combination that building condition is the second floor (the number of floors), sloped roof (roof shape) and construction area is any of 4-7 area (see the second step in the table in Figure 7) The reference part heat insulation specification of the housing part M1 is the high heat insulation specification G1, and the reference part heat insulation specification of the floor base part M2 is the floor heat insulation specification.

  Returning to the description of FIG. 5, the heat insulation specification initial setting unit 31 initializes the heat insulation specification of the building X by setting the area heat insulation specification for each of the skin parts M1 to M4 of the building X. The heat insulation specification initial setting unit 31 acquires the building condition of the building X acquired by the building condition acquiring unit 34 and the construction area acquiring unit 35 for the casing site M1 and the floor foundation site M2 among the respective skin sites M1 to M4. The site insulation specification is set based on the construction area of the building X. In this setting, specifically, the heat insulation specification initial setting unit 31 acquires, from the heat insulation specification database 36, a reference area heat insulation specification corresponding to the combination of the acquired building condition of the building X and the construction area for the casing part M1. , The acquired reference part heat insulation specification is set as a part heat insulation specification of the housing part M1. Similarly to this, the heat insulation specification initial setting unit 31 acquires, from the heat insulation specification database 36, the reference area heat insulation specification corresponding to the combination of the acquired building condition of the building X and the construction area for the floor foundation area M2. The acquired standard part heat insulation specification is set as a part heat insulation specification of the floor foundation part M2. In this case, the casing site M1 and the floor foundation site M2 correspond to "predetermined insulating function sites".

  In the present embodiment, the building condition of the building X is the second floor, sloped roof, and the construction area of the building X is four areas. Therefore, referring to FIG. 7 (insulation specification database 36), the reference site insulation specification of the housing part M1 corresponding to the combination of the building conditions and the construction area is the high insulation specification G1, and the reference site insulation specification of the floor foundation part M2 Is the floor insulation specification (see the second step in the table of FIG. 7). Therefore, in this case, the heat insulation specification initial setting unit 31 sets the high heat insulation specification G1 as the part heat insulation specification of the housing part M1 of the building X, and sets the floor heat insulation specification as the part heat insulation specification of the floor foundation part M2.

  Further, the heat insulation specification initial setting unit 31 sets the area heat insulation specification based on the design data of the building X for the window area M3 and the door area M4. For example, the design data of the building X includes specification information of the sash used in the window portion M3, and the heat insulation specification initial setting unit 31 determines the heat insulation specification of the sash based on the specification information of the sash, that is, the window Set the part heat insulation specification of the part M3.

  As described above, in the heat insulation specification initial setting unit 31, the heat insulation specification of the building X is initialized by setting the area heat insulation specification for each of the skin parts M1 to M4 of the building X.

  Next, the flow of the heat insulation design support process will be described in detail using the flowchart shown in FIG. FIG. 8 is a flowchart showing the flow of the heat insulation design support process. The present process is performed by the control unit 11, and more specifically, is performed by the functional blocks 21 to 25 of the control unit 11. Further, the present process is triggered by the start operation of the operation unit 12 by the user as a trigger.

  As shown in FIG. 8, first, in step S11, the heat insulation specification setting unit 22 (specifically, the heat insulation specification initial setting unit 31) performs heat insulation specification initialization processing for initializing the heat insulation specification of the building X. By this processing, as described above, the site heat insulation specification is set (initially) for each of the skin sites M1 to M4 of the building X. The heat insulation specification initialization process corresponds to the first heat insulation specification initialization process.

  In step S12, the heat insulation performance calculation unit 23 calculates the heat insulation performance of the building X based on the design data of the building X and the heat insulation specification of the building X that has been initially set. In the subsequent step S13, the target determination unit 24 determines whether the heat insulation performance of the building X calculated above has reached the target heat insulation performance. If the calculated thermal insulation performance of the building X has reached the target thermal insulation performance, the process proceeds to step S18. If the thermal insulation performance does not reach the target thermal insulation performance, the process proceeds to step S14.

  In step S14, the first repetitive processing is repeated to repeat resetting of the heat insulation specification of the building X until the heat insulation performance of the building X calculated by the heat insulation performance calculation unit 23 reaches the target heat insulation performance. Hereinafter, the first repeated process will be described based on a flowchart shown in FIG. The first repeated process corresponds to the first repeating means.

  As shown in FIG. 9, in the first repeated processing, first, in step S31, the heat insulation specification setting unit 22 (more specifically, the heat insulation specification reset unit 32 resets the heat insulation specification of the building X) I do. In this process, for the casing site M1 among the hull parts M1 to M4 of the building X, the casing site M1 among the respective site thermal insulation specification candidates (specifically, the standard thermal insulation specification and the respective high thermal insulation specifications G1 to G4) The site heat insulation specification candidate having a higher heat insulation effect than the site heat insulation specification currently set (currently) is re-set as the area heat insulation specification of the housing site M1 (corresponding to the area heat insulation specification resetting means). Specifically, among the heat insulation specification candidates for each part, among the candidates having a higher heat insulation effect than the part heat insulation specification set for the case part M1, the one having the lowest heat insulation effect is set as the part heat insulation specification for the case part M1. Do. Thereby, the site | part heat insulation specification of the housing site | part M1 is reset to a thing with a high heat insulation effect, and the heat insulation specification of the building X is reset to a thing with a high heat insulation effect by extension. The process (first heat insulation specification resetting process) in step S31 corresponds to first heat insulation specification resetting means and third heat insulation specification resetting means. In addition, the casing site M1 corresponds to the "first heat insulation function area" and the "heat insulation function area different from the appearance affected area".

  Further, in the first heat insulation specification resetting process, the area heat insulation specification is reset only for the casing site M1 among the skin parts M1 to M4. Therefore, in the present resetting process, the (currently) set site heat insulation specification is maintained as it is for each of the skin sites M2 to M4 other than the casing site M1.

  In step S32, the heat insulation performance calculation unit 23 recalculates the heat insulation performance of the building X based on the design data of the building X and the heat insulation specification of the building X reset in step S31. In the subsequent step S33, the target determination unit 24 determines whether or not the thermal insulation performance of the recalculated building X has reached the target thermal insulation performance. If the calculated thermal insulation performance has reached the target thermal insulation performance, the process proceeds to step S39, and a target achievement flag is set.

  In the subsequent step S40, storage processing is performed to store the processing result of the first repetitive processing in the storage unit 14. In this process, the heat insulation specification set for the building X is stored in the storage unit 14 when it is determined that the calculated heat insulation performance of the building X has reached the target heat insulation performance as the above processing result. Do. Specifically, in this case, the part heat insulation specification set in each of the skin parts M1 to M4 of the building X at the time of target achievement determination is stored in the storage unit 14 respectively. Further, in this processing, in addition to the heat insulation specification of the building X, the heat insulation performance of the building X at the time of target achievement determination, and more specifically, the UA value is stored in the storage unit 14 as the processing result. After the step S40, the present process is ended.

  If it is determined in step S33 that the calculated heat insulation performance of the building X has not reached the target heat insulation performance, the process proceeds to step S34. In step S34, the high heat insulation specification G4 having the highest heat insulation effect among the respective area heat insulation specification candidates (standard heat insulation specification and each high heat insulation specification G1 to G4) is set as the area heat insulation specification of the housing part M1 in the building X Determine if there is. When the high heat insulation specification G4 is not set as the part heat insulation specification of the housing part M1, the process returns to step S31, and the first heat insulation specification resetting process is performed again. And after that, each process of step S32-S34 is performed again. That is, in this case, each process of steps S31 to S34 is repeatedly performed until the high heat insulation specification G4 is set as the area heat insulation specification of the housing part M1 (unless determined as YES in step S33).

  In step S34, if the high heat insulation specification G4 is set as the part heat insulation specification of the housing part M1, the process proceeds to step S35, and whether or not the basic heat insulation specification is set as the part heat insulation specification of the floor base part M2 judge. When the base heat insulation specification is set as the part heat insulation specification of the floor base area M2, the present processing is ended. The basic heat insulation specification is a part heat insulation specification candidate having the highest heat insulation effect among the respective part heat insulation specification candidates (specifically, the floor heat insulation specification and the basic heat insulation specification) of the floor foundation part M2. Therefore, in this case, for each of the casing site M1 and the floor foundation site M2, the site insulation specification candidate having the highest insulation effect (that is, the high insulation specification G4 and the base insulation specification) is set as the area insulation specification. Even in that case, the heat insulation performance of the building X does not reach the target heat insulation performance. Therefore, in this case, this process is ended as it is.

  In step S35, when the floor heat insulation specification is not set as a part heat insulation specification of the floor foundation part M2, it progresses to step S36. In step S36, the heat insulation specification resetting unit 32 performs a second heat insulation specification resetting process for resetting the heat insulation specification of the building X. In this process, a part of the floor heat insulation specification candidate (specifically, the floor heat insulation specification and the foundation heat insulation specification) of the floor base area M2 of the building X, the area heat insulation set (currently) to the floor base area M2 A site heat insulation specification candidate (that is, basic heat insulation specification) having a higher thermal insulation effect than the specification (that is, floor heat insulation specification) is set again as the area heat insulation specification of the floor foundation area M2 (corresponding to the site heat insulation specification reset means) . As a result, the part adiabatic specification of the floor foundation part M2 is reset to one having a higher adiabatic effect. Further, in the second heat insulation specification resetting process, the area heat insulation specification for improving the heat insulation effect as described above is reset only for the floor base area M2 among the skin parts M1 to M4. In addition, the process of this step S35 (second heat insulation specification resetting process) corresponds to the second heat insulation specification resetting means and the third heat insulation specification resetting means. In addition, the floor base portion M2 corresponds to the "second adiabatic function portion" and the "adiabatic function portion different from the appearance affected portion".

  Further, in the second adiabatic specification resetting process, among the respective adiabatic region specification candidates (standard adiabatic specification and high adiabatic specification G1 to G4), the region set (currently) in the case region M1 for the case region M1. The area heat insulation specification candidate having lower heat insulation performance than the heat insulation specification (that is, the high heat insulation specification G4) is reset as the area heat insulation specification of the housing part M1. Specifically, among the respective part heat insulation specification candidates, the standard heat insulation specification having the lowest heat insulation performance is reset as the part heat insulation specification of the housing part M1.

  In step S37, the heat insulation performance calculation unit 23 recalculates the heat insulation performance of the building X based on the design data of the building X and the heat insulation specification of the building X reset in step S36. In the subsequent step S38, the target determination unit 24 determines whether or not the heat insulation performance of the recalculated building X has reached the target heat insulation performance. If the calculated thermal insulation performance has reached the target thermal insulation performance, a target achievement flag is set in step S39, and then storage processing is performed in step S40. Thereafter, the process ends.

  On the other hand, when the calculated thermal insulation performance does not reach the target thermal insulation performance, the process returns to step S31, and the first thermal insulation specification resetting process is performed again. And after that, each process of step S32-S34 is performed again. That is, in this case, each process of steps S31 to S34 is repeated until the high heat insulation specification G4 is set as the area heat insulation specification of the housing part M1 (unless determined as YES in step S33).

  As described above, in the first repeated processing, resetting of the adiabatic specification is repeatedly performed by the first adiabatic specification resetting process and the second adiabatic specification resetting process until the calculated adiabatic performance reaches the target adiabatic performance. . Further, in the first repeated processing, when the resetting of the heat insulation specification of the building X is repeated, the heat insulation specification of the housing site M1 or the floor base area M2 is reset (changed) while the window area M3 and the door site The site insulation specification is not reset (changed) for M4. That is, in the first repeated processing, in the repetition of resetting of the heat insulation specification of the building X, the area heat insulation specification of the window part M3 is maintained as the heat insulation sash specification set at the time of initialization of the heat insulation specification. The part heat insulation specification is maintained with the door specification H1 set at the time of initialization of the heat insulation specification.

  Here, the flow of resetting of the heat insulation specification when the resetting of the heat insulation specification of the building X is repeated by the above-described first repeated process will be described with reference to FIG. FIG. 10 is a table for explaining the flow of resetting of the heat insulation specification of the building X. In this table, a process number is given for each setting process of the heat insulation specification, and the contents of the heat insulation specification to be set (more specifically, the area heat insulation specification set for each of the skin parts M1 to M4) It is shown. Further, in this table, each setting process assigned a process number is arranged in the order of processes in which the process is performed as a whole.

  As described above, in the first repeated processing, in the repetition of resetting of the adiabatic specification of the building X, the adiabatic sash specification is not changed for the site adiabatic specification of the window part M3, and the site adiabatic specification of the door part M4 is not changed. Do not change the door specification H1. Therefore, referring to FIG. 10, in the first repeated processing, resetting of the adiabatic specification of the building X is performed (flowing) in the order of ... → 4 → 7 → 10 → 13 → ... as the process number. .

  Here, as described above, in the heat insulation specification initialization process (step S11) of the building X performed prior to the first repeated process (step S14), the area heat insulation specifications of the outer skin parts M1 to M4 of the building X are respectively , High thermal insulation specification G1 (M1), floor thermal insulation specification (M2), thermal insulation sash specification (M3), door specification H1 (M4). Therefore, in FIG. 10, this initial setting corresponds to process number 4. Therefore, in this case, the first repeated processing (that is, repeated resetting of the adiabatic specification) is performed, starting from the process number 4 (the adiabatic specification). In FIG. 10, black circles are attached to the column of the process number 4 (first repeated process column).

  In the first repeated processing, the resetting is repeatedly performed in the above-described resetting processing order (processing number ... → 4 → 7 → 10 → 13 → ... in this order). Therefore, the process of resetting the process number 7 is performed first. At the time of this resetting, the part heat insulation specification of the housing part M1 is reset to the high heat insulation specification G2 (first heat insulation specification resetting process in step S31). In FIG. 10, white circles are added to the column of the process number 7 (first repeated process column).

  Here, in FIG. 10, a target line indicating a target adiabatic performance is shown as a reference. Specifically, this target line is a line indicating a target value Uo (0.6) of the UA value. Above the target line, the UA value is higher than the target value Uo, and below the target line, the UA value is lower than the target value Uo.

  The resetting process of process number 7 is located above the target line. Therefore, in this case, in the heat insulation specification set in the process, the UA value of the building X exceeds the target value Uo, and the target heat insulation performance can not be obtained (NO in step S33). Therefore, the process of resetting the process number 10 is performed next. At the time of this resetting, the part heat insulation specification of the housing part M1 is reset to the high heat insulation specification G3 (first heat insulation specification resetting process in step S31). In FIG. 10, white circles are added to the column of the process number 10 (first repeated process column).

  The resetting process of process number 10 is located below the target line. Therefore, in this case, the UA value of the building X becomes equal to or less than the target value Uo according to the heat insulation specification set in the process, and the target heat insulation performance can be obtained (YES in step S33). Thus, the repetition of the resetting by the first repetition processing ends.

  Returning to the explanation of FIG. 8, in step S15 after the first repetitive process (step S14), it is determined whether or not the target achievement flag is set. If the target achievement flag is not set, that is, if the target adiabatic performance is not obtained in the first repeated processing, the present processing is ended. On the other hand, when the target achievement flag is set, that is, when the target heat insulation performance is obtained in the first repeated processing, the process proceeds to step S16.

  Here, in the thermal insulation design support process, when the target thermal insulation performance is obtained for the building X by the first repeated process (thus, the processing of steps S11 to S14), the thermal insulation of the building X is the target thermal insulation again A process of repeating the setting of the heat insulation specification of the building X is performed in steps S16 and S17 until the performance is reached. The process of steps S16 and S17 differs from the process of steps S11 to S14 described above in the flow of setting of the heat insulation specification, and the process of steps S16 and S17 will be described below.

  First, in step S16, the heat insulation specification setting unit 22 performs a second heat insulation specification initialization process for initializing the heat insulation specification of the building X. In this process, the heat insulation specification is initialized using the result of the first repeated process. Specifically, at the time of the target achievement determination (when YES is determined in step S33 or S38) it is determined in the first repeated processing that the heat insulation performance of the building X has reached the target heat insulation performance. The insulation specification set immediately before the set insulation specification is initially set as the insulation specification of the building X.

  This point will be described with reference to FIG. 10. The heat insulation specification set for the building X at the time when the heat insulation performance of the building X reaches the target heat insulation performance in the first repeated processing (at the time of target achievement determination) is the processing number 10 insulation specifications. And the heat insulation specification set immediately before that is the heat insulation specification of the processing number 7. For this reason, the heat insulation specification of this process number 7 is initialized as a heat insulation specification of the said building X here. In FIG. 10, the box of the process number 7 (second repeated process box) is indicated by a black square. Further, the process of the present step S16 (second heat insulation specification initialization process) corresponds to the second heat insulation specification initialization means.

  In step S17, the heat insulation specification resetting unit 32 performs the second iterative process of repeatedly resetting the insulation specification of the building X until the heat insulation performance of the building X calculated in the heat insulation performance calculating unit 23 reaches the target heat insulation performance. . Below, this 2nd repetition processing is explained based on the flow chart shown in FIG. The second repeated process corresponds to a second repeating unit.

  As shown in FIG. 11, in the second repeated processing, first, in step S51, the heat insulation specification resetting unit 32 performs a third heat insulation specification resetting process for resetting the heat insulation specification of the building X. In this process, the heat insulation specification candidate of the area heat insulation specification candidate (specifically, door specification H1 to H3) of the door area M4 of the building X is more thermally insulated than the area heat insulation specification currently (currently) set for the door area M4. A highly effective part heat insulation specification candidate is reset as a part heat insulation specification of the door part M4 (corresponding to part heat insulation specification reset means). Specifically, among the heat insulation specification candidates for each part, among the candidates having a higher heat insulation effect than the part heat insulation specification set for the door part M4, the lowest heat insulation effect is set as the part heat insulation specification for the door part M4. Do. Thereby, the site | part heat insulation specification of the door site | part M4 is reset to a thing with a high heat insulation effect, and the heat insulation specification of the building X is reset to a thing with a high heat insulation effect by extension. In addition, the process of this step S51 (third heat insulation specification resetting process) corresponds to the fourth heat insulation specification resetting means. Further, the door portion M4 corresponds to the "appearance affected portion".

  Further, in the third heat insulation specification resetting process, the area heat insulation specification is reset only for the door area M4 among the outer skin areas M1 to M4. Therefore, in the present resetting process, the (currently) set-part heat insulation specification is maintained as it is for each of the skin parts M1 to M3 other than the door part M4.

  In step S52, the heat insulation performance calculation unit 23 recalculates the heat insulation performance of the building X based on the design data of the building X and the heat insulation specification of the building X reset in step S51. In the subsequent step S53, the target determination unit 24 determines whether or not the thermal insulation performance of the recalculated building X has reached the target thermal insulation performance. If the calculated thermal insulation performance has reached the target thermal insulation performance, the process proceeds to step S55.

  In step S55, a storage process is performed to store the heat insulation specification set for the building X in the storage unit 14 when it is determined that the calculated heat insulation performance has reached the target heat insulation performance. In this storage processing, the part heat insulation specification set in each of the skin parts M1 to M4 of the building X at the time of the target achievement determination is stored in the storage unit 14 respectively. Further, in the memory processing, in addition to the heat insulation specification of the building X, the heat insulation performance of the building X at the time of the target achievement determination, specifically, the UA value is also stored in the storage unit 14. After the present step S55, the present process ends.

  If it is determined in step S53 that the calculated thermal insulation performance of the building X has not reached the target thermal insulation performance, the process proceeds to step S54. In step S54, it is determined whether the door specification H3 having the highest heat insulation effect is set among the respective part heat insulation specification candidates (each door specification H1 to H3) as the part heat insulation specification of the door part M4 in the building X . If the door specification H3 is not set as the part heat insulation specification of the door part M4, the process returns to step S51, and the third heat insulation specification resetting process is performed again. And after that, each process of step S52-S54 is performed again. That is, in this case, each process of steps S51 to S54 is repeated until the door specification H3 is set as the area heat insulation specification of the door area M4 (unless determined YES in step S53).

  When the door specification H3 is set as the part heat insulation specification of the door part M4 in the step S54, the present process is ended. In this case, the thermal insulation performance of the building X did not reach the target thermal insulation performance even when the door specification H3 having the highest thermal insulation effect among the respective thermal insulation specification candidates is set as the thermal insulation specification of the door part M4. become. Therefore, in this case, this process is ended.

  Subsequently, the flow of resetting the heat insulation specification when the resetting of the heat insulation specification of the building X is repeated by the above-described second repeated process will be described with reference to FIG.

  As described above, in the heat insulation design support process, the second heat insulation specification initialization process (step S16) is performed prior to the second repeated process (step S17). Then, in this initial setting process, the heat insulation specification of the process number 7 is set. Therefore, in this case, the second repeated process (that is, repeated resetting of the adiabatic specification) is performed, starting from the process number 7 (the adiabatic specification).

  As described above, in the second repeated processing, when the heat insulation specification of the building X is reset, only the heat insulation specification of the door area M4 among the outer skin areas M1 to M4 is reset. Therefore, in the second repeated process, resetting of the heat insulation specification of the building X is performed (flowed) in the order of 7 → 8 → 9 as the process number. Therefore, in the second repeated process, the process of resetting process number 8 is first performed. At the time of this resetting, the part heat insulation specification of the door part M4 is reset to the door specification H2 (third heat insulation specification resetting process of step S51). Note that, in FIG. 9, a box with a white outline is added to the column of the process number 8 (second repeated process column).

  The setting process of the process number 8 is located above the target line. Therefore, in this case, in the heat insulation specification set in the setting process, the UA value of the building X exceeds the target value Uo, and the target heat insulation performance can not be obtained (NO in step S53). Therefore, the resetting process of the process number 9 is performed next. At the time of this resetting, the part heat insulation specification of the door part M4 is reset to the door specification H3 (third heat insulation specification resetting process of step S51). In FIG. 9, the box of the process number 9 (second repeated process box) is indicated by an open square.

  The setting process of the process number 9 is located below the target line. Therefore, in this case, according to the heat insulation specification set in the setting process, the UA value of the building X becomes equal to or less than the target value Uo, and the target heat insulation performance can be obtained (YES in step S53). Thus, the repetition of the resetting by the second repetition processing ends.

  Returning to the description of FIG. 8, in step S18 after the second iterative process (step S17), the output unit 25 displays the processing result of the first iterative process and the processing result of the second iterative process on the display unit 13. Perform output processing to output. In this process, the process result of each repetitive process stored in the storage unit 14 is read out, and the process result is displayed on the display unit 13.

  The display screen on which the process result was displayed on the display part 13 is shown by FIG. As shown in FIG. 12, on the display screen, the processing result of the first repeated processing is shown in the column of “Specification 1” and the processing result of the second repeated processing is shown in the column of “Specification 2”. In “Specification 1”, in the first repeated processing, the UA value (0.59) of the building X calculated when achieving the target of thermal insulation performance and the heat insulation specification of the building X that was set when the target was achieved (FIG. And (corresponding to the heat insulation specification of the process number 10) are displayed respectively. Similarly, in "Specification 2", in the second repeated processing, the UA value (0.60) of the building X calculated when achieving the goal of thermal insulation performance and the heat insulation of the building X that was set when the goal was achieved The specifications (corresponding to the heat insulation specification of the process number 9 in FIG. 10) are displayed respectively. Moreover, about heat insulation specification, the site | part heat insulation specification of each outer_skin | epidermis site | part M1-M4 is each displayed. In this case, since a plurality of heat insulation specifications (“specification 1” and “specification 2”) are presented as the heat insulation specifications capable of obtaining the target heat insulation performance in the building X, the user determines the heat insulation specification of the building X It is possible to expand the range of choices.

  Further, on the lower right of the display screen, cost information related to the cost of the heat insulation specification is displayed. As the cost information, for example, information on the cost difference between “specification 1” and “specification 2” is displayed. In FIG. 12, the difference of the thermal insulation specification of the skin part (specifically, the casing part M1, the door part M4) of the "specification 1" and the "specification 2" is displayed as the difference information. In this case, when the user determines the heat insulation specification of the building X, it can be determined in consideration of not only the heat insulation performance of the building X but also the cost.

  In the output process, when the process result of the second repeated process is not obtained (when YES in step S54 of FIG. 11), only the process result of the first repeated process is output to the display unit 13. .

  According to the configuration of the embodiment described above, the following excellent effects can be obtained.

  While acquiring the number of floors of the building X and the roof shape as building conditions, the information of the construction area where the building X is constructed was acquired. And the insulation specification of the building X was initially set based on the building conditions and construction area of the building X which were acquired. Both the construction area of the building and the building conditions (the number of floors and the shape of the roof) are considered to be factors that greatly affect the heat insulation performance of the building. Therefore, in this case, the insulation specification of the building X is initialized based on the construction area of the building X and the building conditions, whereby the insulation specification suitable for the construction area and the building conditions can be initialized. In this way, it is possible to avoid that the thermal insulation performance of the building X calculated based on the initially set thermal insulation specification falls far below the target thermal insulation performance, so the thermal insulation performance of the building X reaches the target thermal insulation performance. It is possible to reduce the number of re-setting of the adiabatic specification which is repeated repeatedly. Therefore, in this case, the number of man-hours can be reduced when obtaining the heat insulation specification that can obtain the target heat insulation performance.

  In the above building conditions (the number of floors and the shape of the roof), when the number of floors is different, the area of the outer wall in the buildings will be different when the number of floors is different. It is possible to come out. In addition, regarding the roof shape of the building, for example, the vertical height of the attic space is significantly different between the sloped roof (for example, the roof for roof and the roof for gable roof) and the flat roof, so that the heat insulation performance may be significantly different. Therefore, as described above, it is preferable to obtain the number of floors of the building X and the roof shape as the building condition and initialize the heat insulation specification based on the building condition in order to initialize the heat insulation specification suitable for the building X It can be said.

  When the heat insulation specification of the building X is initially set, the part heat insulation specification is set for each of the skin parts M1 to M4 of the building X so as to be initially set. And about each housing site | part M1 and the floor | bed base site | part M2 among each outer_skin | skin_skin site | part M1-M4, the site | part heat insulation specification was set using the heat insulation specification database 36. In this case, the heat insulation specification database 36 can be used to set the heat insulation specification suitable for the construction area of the building X and the building conditions for the housing part M1 and the floor foundation part M2, and as a result thereof , It becomes possible to initialize the insulation specification suitable for the construction area and the building conditions of the building X.

  In resetting the heat insulation specification of the building X, the skin part of any one of the skin parts M1 to M4 of the building X has a part heat insulation having a higher heat insulation effect than the part heat insulation specification set for the skin part The specification candidate is set again as the site heat insulation specification of the skin portion (steps S31, S36, and S51). For example, in step S31 (the first adiabatic specification resetting process), only for the casing site M1 among the outer skin sites M1 to M4, a site adiabatic specification having a higher adiabatic effect than the site insulation specification set for the casing site M1. It was decided to reset the candidate as a part adiabatic specification of the housing part M1. In this case, at the time of resetting of the heat insulation specification of the building X, the heat insulation performance is enhanced only at any one of the skin parts of the skin parts M1 to M4 of the building X. For this reason, it is possible to increase the thermal insulation performance of the building X little by little by resetting the thermal insulation specification, and as a result, the thermal insulation performance of the building X greatly exceeds the target thermal insulation performance by resetting the thermal insulation specification ( It is possible to avoid the occurrence of so-called excessive specifications.

  In the first repeated processing (FIG. 9), when the thermal insulation specification of the building X is repeatedly reset, the thermal insulation specification is reset by the first thermal insulation specification reset process (step S31), and the second thermal insulation specification reset process ((step S31) Among the re-setting of the heat insulation specification in step S36), the re-setting of the heat insulation specification by the first heat insulation specification re-setting process is performed with priority. Specifically, for the casing part M1, priority is given to resetting by the first adiabatic specification resetting process until the high adiabatic specification G4 having the highest adiabatic effect among the respective part thermal insulation specification candidates is set as the part adiabatic specification. I decided to do it. In this case, since the re-setting of the part adiabatic specification for the same outer skin part (that is, the part M1) is prioritized, when the re-setting of the adiabatic specification is repeated, the adiabatic performance of only the part M1 is increased gradually Be For this reason, when setting the heat insulation specification is repeated, it can be said that it is a preferable configuration in order to increase the heat insulation performance of the building X little by little.

  When the high heat insulation specification G4 having the highest heat insulation effect is set as the part heat insulation specification for the housing part M1, the heat insulation specification is reset by the first heat insulation specification resetting process (step S31) and the second heat insulation specification Among the resetting of the heat insulation specification by the resetting process (step S36), it is determined that the heat insulating specification is reset by the second heat insulation specification resetting process. Then, in the second heat insulation specification resetting process, the heat insulation specification candidate having a lower heat insulation effect than the heat insulation specification set for the housing area M1 is re-selected as the heat insulation specification for the housing area M1. I decided to set it. In this case, in order to increase the heat insulation performance of the building X little by little when the resetting of the heat insulation specification is repeated, a more preferable configuration can be obtained.

  Repeated processing was repeated to repeatedly reset the insulation specification of the building X until the target determination unit 24 determined that the calculated insulation performance of the building X reached the target insulation performance. Specifically, as such repeated processing, the first repeated processing (FIG. 9) is performed to repeat resetting of the heat insulation specification by the first heat insulation specification resetting processing (step S31) and the second heat insulation specification resetting processing (step S36). And a second repeated process (FIG. 11) in which the heat insulation specification is reset again by the third heat insulation specification reset process (step S51). Here, in the first adiabatic specification resetting process and the second adiabatic specification resetting process, the site adiabatic specification is reset with respect to the casing site M1 and the floor foundation site M2, and in the third adiabatic specification resetting process, the door site M4 Reset the site insulation specification. In this case, the housing part M1 and the floor foundation part M2 are appearance non-influenced parts where the part insulation specification does not affect the appearance, while the door part M4 is the appearance affected part where the part insulation specification affects the appearance ing. Therefore, while repetition of resetting by the first repetition processing does not affect the appearance of the building, repetition of resetting by the second repetition processing affects the appearance of the building.

  And in said embodiment, the heat insulation performance of the building X is the case where the heat insulation performance of the building X becomes a target heat insulation performance by repetition of the reset by 1st repetition processing, and the repetition of the reset by 2nd repetition processing It was decided to output the heat insulation specification set for the building X at the time of achieving the target to the display unit 13 for each of the cases where the target heat insulation performance was achieved. In this case, since a plurality of heat insulation specifications having different building appearances are output to the display unit 13, the user can determine the heat insulation specifications of the building X while considering the appearance of the building X as well.

  The repetition of the resetting by the first repetition processing was performed before the repetition of the resetting by the second repetition processing. In addition, before the repetition by the second repetition processing, the second heat insulation specification initialization process (step S16 in FIG. 8) is performed to initialize the heat insulation specification of the building X, and in the second heat insulation specification initialization process, It was decided to perform initialization using the result of the repeated processing. Specifically, in the initial setting process, in the first repeated process, the heat insulation performance of the building X is set immediately before the heat insulation specification set for the building X when the target achieved the desired heat insulation performance. The thermal insulation specification was initially set as the thermal insulation specification of the building X. In this case, the heat insulation performance of the building X can be brought close to the target heat insulation performance by the initial setting of the heat insulation specification. For this reason, in the second repeated processing, when the resetting of the heat insulation specification is repeated until the heat insulation performance of the building X reaches the target heat insulation performance, the number of repetitions can be reduced, and the number of man-hours can be reduced.

  The present invention is not limited to the above embodiment, and may be implemented, for example, as follows.

  In the above embodiment, the first repeated process (step S14) and the second repeated process (step S17) are performed as the repeated process. However, among the respective repeated processes, only the first repeated process is performed. May be In this case, in the output process by the output unit 25, only the processing result of the first repetitive process is output to the display unit 13.

  -In the above embodiment, the heat insulation specification is repeatedly reset in the second repeated process only by the third heat insulation specification reset process (step S51), but it is changed, for example, the third heat insulation specification reset process and You may carry out by the 1st heat insulation specification reset process.

  In the above embodiment, in the second heat insulation specification initialization process (step S16), the heat insulation specification of the building X is initialized using the result of the first repetition process. There is no need to use the results. For example, the insulation specification of the building X may be initialized based on an input operation by the user.

  In the above embodiment, the heat insulation design support system in the present invention is configured by one device (more specifically, the heat insulation design support device 10), but is configured by a plurality of devices interconnected via a network such as the Internet May be
