Description

  The present invention relates to a housing simulation system and program.

  In recent years, awareness of environmental issues has increased, and companies have been reviewing factories and product production lines to reduce carbon dioxide emissions. Also in homes, carbon dioxide is generated during construction, and environmentally responsive measures are required.

  From the viewpoint of suppressing carbon dioxide emission, it can be said that trees absorb and fix carbon dioxide by photosynthesis. The trees are cut into timber and used as raw materials for building materials such as pillars, beams, foundations, outer wall materials, inner wall materials, and roofing materials when constructing houses. In this case, the carbon dioxide absorbed by the wood is fixed in the building material and is effective as a means for fixing the carbon dioxide.

  In addition, there are building materials that are manufactured using thinned wood. For example, Patent Document 1 discloses a method of manufacturing an outer wall material using thinned material. When a house is constructed using such a building material, the thinned material can be effectively used and absorbed by the thinned material. Carbon dioxide is fixed in building materials, and in the thinned forest, tree growth is promoted and carbon dioxide absorption is increased.

On the other hand, there are building materials that do not use wood at all. For example, Patent Document 2 discloses a lightweight cellular concrete board, which is formed after placing a raw material slurry mainly composed of a siliceous raw material and a calcareous raw material on a molding form. Since it is manufactured by curing in an autoclave and does not contain wood, the carbon dioxide absorption is zero and the carbon dioxide fixation is zero.
Thus, the amount of carbon dioxide absorbed and the amount of carbon dioxide fixed by the building material vary greatly depending on whether or not wood is included.

  However, in the past, when designing a house, carbon dioxide fixation amount, carbon dioxide absorption amount, carbon credit, etc. have not been considered, design drawings are created, floor plans, roof shapes, windows, etc. After determining the position of the opening, the construction of the inner wall and the outer wall is stopped by arranging a plurality of building materials having various shapes, dimensions, patterns, patterns, and colors. The “carbon dioxide fixation amount” is an amount that is considered to be absorbed and fixed by the construction material containing wood. “Carbon dioxide absorption” is the amount of carbon dioxide that is considered to be absorbed in the growth process by the forest where the timber is produced because the building material contains thinned timber, and the timber contained in the building material is It includes the amount of carbon dioxide absorbed and the amount of carbon dioxide that the forest will absorb in the future growth process. “Carbon credit” is a proof of emissions reduction of greenhouse gases that can be traded. As described above, these “carbon dioxide fixation amount, carbon dioxide absorption amount, carbon credit” are different indicators, but all are indicators of the greenhouse gas emission reduction amount.

  For example, Patent Document 3 discloses a system that realizes a simulation for creating an exterior design of a house between a server and a client connected via a network. According to this system, by using a client device, data such as building material images necessary for simulation is acquired from the server device, and pasted on house image data or the like that is held in advance in the client device. However, it is not possible to calculate and take into account carbon dioxide fixation, carbon dioxide absorption, carbon credits, etc.

The building material file has environmental impact value data for each building material. The house design specification setting unit sets the design specifications of the house. The building material setting unit sets building materials. The calculation unit calculates the amount of building material required. Specifically, the calculation unit is configured to execute the target value setting unit based on the environmental impact value of the house set by the target value setting unit, the house design specification set by the house design specification setting unit, and the database information. Calculate the amount of building materials required for the environmental impact value of the set house. In addition, the calculating part can also calculate the quantity of building materials required for the environmental impact value of the house set by the target value setting part about the building materials set by the building material setting part.

Also, when deciding on a house, the degree of contribution to the environment can be clearly taken into account by numerical values.

In addition, the housing simulation system of the present invention is set for each building material by the housing design specification setting unit and the amount of building material required for the environmental impact value of the house set by the target value setting unit calculated by the calculation unit. A comparison unit for comparing the amount of building materials required for design specifications of the house, and the environmental impact value is a carbon dioxide fixed amount, a carbon dioxide absorption amount, or a carbon credit . A state in which the amount of building materials required to perform the housing design specifications set by the housing design specification setting unit by the comparison unit is less than the amount of building materials required for the environmental impact value set by the target value setting unit Can be prevented.

The carbon dioxide emission file is stored in the database, and the calculation unit calculates the carbon dioxide emission amount based on the data regarding the customer's self-activity set by the self-activity setting unit and the carbon dioxide emission file. Thus, the customer grasps the carbon dioxide emissions due to self activities, it is possible to set a clear target. The arithmetic unit calculates the necessary environment influence value from the carbon dioxide emissions calculated, the target value setting unit sets the calculated necessary environment influence value as a target value.

  Furthermore, in the housing simulation system of the present invention, the building material setting unit further presents to the customer as only applicable building materials applicable to the set design specifications of the house, and the building materials set by the customer are selected. It can also be determined. For example, the design specification file may include building material data applicable to each design specification so that only applicable building materials can be selected, or the design specification data applicable to each building material may be selected in the building material file. It is possible to include only the building materials that can be included in the housing design specification set by the housing design specification setting unit. Thereby, it can prevent selecting the building material which a customer cannot construct.

Further, the housing simulation system of the present invention, the design specification file, preferably having a data quantity required applicable building materials for each design specification, since the calculation of the environmental impact value of housing is smooth. In this case, the calculation unit calculates the amount of building material necessary for the environmental impact value of the house set by the target value setting unit for applicable building materials, and the comparison unit calculates the applicable building materials for Comparing the required amount of building materials calculated by the calculation unit with the required amount of building materials stored in the design specification file , set applicable building materials, and the building material setting unit can be applied by the comparison unit Only the judged building material can be presented to the customer as an applicable building material, and the building material selected by the customer can be determined as the set building material. Thereby, it can prevent selecting the building material which cannot satisfy | fill the target which the customer set. For the setting of applicable building materials by the comparison unit, specifically, the required amount stored in the design specification file or building material file for carbon dioxide fixed amount, carbon dioxide absorption amount, and carbon credit is better. This is the case.

  FIG. 5 is a flowchart schematically showing a processing flow in the first embodiment. Next, a usage pattern of the house simulation system according to the first embodiment configured as described above and operations of the client device 120 and the server device 100 will be described in detail.

  In the first embodiment, first, a target is set (step S11). FIG. 6 is an example of a screen for setting the environmental impact value of the house in the first embodiment, which is displayed by the target value setting unit 203, so that the customer can set the environmental impact value of the target house (for example, dioxide dioxide). Enter carbon fixation, carbon dioxide absorption, or carbon credits). In FIG. 6, a reference button is provided to refer to reference data for input. Then, by clicking the determination button 301, the value input by the customer is set as a target value in this simulation by the target value setting unit 203 and stored in the storage unit 201 of the server 210. Clicking on the return button 302 returns to the previous screen, and clicking the help button 303 displays the operation explanation screen.

  Next, the design specification of the house is set (step S12). FIG. 7 is an example of a screen for setting the design specifications of the house in the first embodiment. The house design linked to the house design specifications included in the design specification file 221 by the house design specification setting unit 204 is shown in FIG. Since the specification is displayed, the customer selects the design specification of the house. In the screen of FIG. 7, since the vertical axis shows the house design specifications and the horizontal axis shows the house building area (total floor area), the customer's desired design specifications and building area intersected. By clicking on the location, you can select the design specifications for the house, including the building area. In FIG. 7, a building area of 30 tsubo is selected for a wooden house, and a black intersection is shown where the vertical axis of the wooden house intersects the horizontal axis of the building area of 30 tsubo. The house design specification selected by the customer is set as the house design specification in this simulation by the house design specification setting unit 204 and stored in the storage unit 201 of the server 210. Since the design specification file 221 includes carbon dioxide emission data associated with construction, these pieces of information are also stored in the storage unit 201.

  Next, the building material setting unit 205 selects a building material that can be applied to the previously set design specification of the house (step S13). Since the design specification data of the design specification file 221 of the database 220 includes a building material product code applicable for each design specification, the building material setting unit 205 sets the design specifications of the house set from the design specification file 221 of the database 220. Design specification data is acquired, and applicable building material product codes included therein are stored in the storage unit 201 of the server 210 as applicable building materials. Since the design specification file 221 also includes assignment data of environmental impact values to each part, these pieces of information are also stored in the storage unit 201.

  When the process of step S13 is completed, a building material is set (step S14). FIG. 8 is an example of a screen for setting a building material in the first embodiment. Since only the building material stored as applicable in step S13 is displayed by the building material setting unit 205, the customer selects a building material. . In the screen of FIG. 8, the customer first extracts the building material to be selected by the usage classification at the left end of the table. In this system, since the building material file 222 includes usage data, it is easy to classify the building materials by usage by using the usage data. Click the lower triangle on the upper right corner of the cell to see a list of usages. Since the pull-down display is performed, the customer can extract the building material to be selected by use. In FIG. 8, if you click the upper right corner of the cell at the left end of the table, a list of columns such as columns, outer walls, roofs, and inner walls will be displayed, so the top cell is the column, and the cell below is the outer wall. Is selected. And to the right of those cells, a cell displaying a product name, product image, price, CO2 fixed amount, CO2 absorption amount, carbon credit, carbon footprint, and detailed information is listed. All of these cells are linked to the cell of usage classification at the left end of the table. In other words, the row is linked to the cell of usage classification. For this reason, in the top row, since a column is selected by use classification, only building materials that can be used as a column are displayed in the product name. The product image, price, CO2 fixed amount, CO2 absorption amount, carbon credit, carbon footprint, detailed information, etc. are linked to the selected product name, and information on the product selected by the product name is displayed. . In the detailed information, more detailed information about the product can be browsed. The building material selected by the customer is set as a building material in this simulation by the building material setting unit 205 and stored in the storage unit 201 of the server 210.

  When the process of step S14 is completed, the number of building materials necessary to satisfy the target is calculated by the calculation unit 206 (step S15). Specifically, in the storage unit 201, the environmental impact value of the target house set by the target value setting unit 203, the design specification of the house set by the house design specification setting unit 204, and the design of the house Since the allocation data of the environmental impact value to each part in the specification, the carbon dioxide emission data associated with the construction in the design specification of the house, and the building material data set by the building material setting unit 205 are held, the calculation unit In 206, using these data, the quantity of each building material to satisfy the target environmental impact value of the house is calculated. More specifically, in order to consider carbon dioxide emissions associated with the construction of houses, each building material is calculated after adding the carbon dioxide emissions associated with construction in the design specifications of the set house from the environmental impact value of the target house. The quantity of is calculated. This calculation can be performed for any of carbon dioxide fixed amount, carbon dioxide absorption amount, and carbon credit. The calculated result is stored in the storage unit 201 of the server 210.

For example, if the number of building materials satisfying the target value of the fixed amount of carbon dioxide is calculated, it can be calculated as follows.
a = (b + c) × (12/44) × 2 / d
Where, a: Quantity of building materials (sheets)
b: Target value of fixed carbon dioxide (kg)
c: Carbon dioxide emissions associated with construction (kg)
d: Wood usage per building material (kg / sheet)
However, 50% of the weight (kg) of timber is carbon (kg) (from the Forestry Agency's document “Quantitative evaluation method for environmental contribution related to timber use (interim report)”).

  When the process of step S15 is completed, the calculation unit 206 calculates the quantity of building materials necessary for the set house (step S16). Specifically, since the storage unit 201 holds the house design specifications set by the house design specification setting unit 204 and the building material data set by the building material setting unit 205, the calculation unit 206 Using these data, the quantity of each building material necessary for the house is calculated. The calculated result is stored in the storage unit 201 of the server 210.

  When the processing in step S16 is completed, the comparison unit 207 then compares the quantity calculated in step S15 with the quantity calculated in step S16 for each building material (step S17). If the quantity calculated in step S16 is smaller than the quantity calculated in step S15, the process returns to step S12 again to make settings from the design specifications of the house.

  If the quantity calculated in step S16 is greater than or equal to the quantity calculated in step S15, the operation is completed, and the obtained result is stored with an operation result code in the operation result file. The customer can store the result calculated in this way in the client device 120 or print it.

  FIG. 9 is a functional block diagram schematically showing the internal configuration of the server apparatus in the second embodiment, and FIG. 10 is a flowchart schematically showing the processing flow. As a second embodiment of the housing simulation system of the present invention, only building materials that satisfy the target value can be selected. For this reason, the server 211 of the second embodiment does not have a comparison unit.

  Also in the second embodiment, first, a target is set (step S21). As a screen for setting the target, FIG. 6 can be used. Since the target setting screen is displayed by the target value setting unit 203, the customer inputs the target environmental impact value (for example, carbon dioxide fixed amount, carbon dioxide absorption amount, or carbon credit). To do. The value input by the customer is set as a target value in the simulation by the target value setting unit 203 and stored in the storage unit 201 of the server 210.

  Next, the design specification of the house is set (step S22). Although the example of the screen which performs the setting of the design specification of the house in this Embodiment 2 is shown in FIG. 11, it can be simplified very much. Since the screen for setting the design specification of the house is displayed by the house design specification setting unit 204, the customer selects the design specification of the house. The selected house design specification is set as a house design specification in this simulation by the house design specification setting unit 204 and stored in the storage unit 201 of the server 210.

  Next, the building material setting unit 205 selects a building material that can be applied to the previously set design specifications of the house (step S23). When the processing of step S23 is completed, the target value is satisfied for each applicable building material. The quantity for this is calculated (step S24). Specifically, in the storage unit 201, the environmental impact value of the target house set by the target value setting unit 203, the design specification of the house set by the house design specification setting unit 204, and the house Allocation data of environmental impact values to each part in the design specification, carbon dioxide emission data associated with construction in the design specification of the house, and building material data set by the building material setting unit 205 are stored. The unit 206 uses these data to calculate the quantity of each building material that satisfies the target environmental impact value of the house. This calculation can be performed for any of carbon dioxide fixed amount, carbon dioxide absorption amount, and carbon credit. The calculated result is stored in the calculation result file 223.

  When the process of step S24 is completed, the building material setting unit 205 selects a building material that can be applied to the previously set design specifications of the house and that satisfies the target value (step S25).
