DETAILED DESCRIPTION OF THE INVENTION

[0016] An embodiment of the present invention (hereinafter referred to as the present embodiment) will be described in detail below with reference to the accompanying drawings. In the drawings, the same or similar components are designated by the same numbers or symbols throughout the description of the present embodiment.

[0017] FIG. 1 is a diagram for explaining an overview of a building-related information acquisition system according to one embodiment of the present invention. 1, the building-related information acquisition system 1 of this embodiment is a system that acquires various information from drawing data of a building. In the following explanation, an example will be described in which the building-related information acquisition system 1 acquires legal compliance information (for example, information necessary for determining energy conservation compliance) from drawing data of a building.

[0018] In the following description, an example will be described in which the building-related information acquisition system 1 acquires legal compliance information (for example, information necessary for determining energy conservation compliance) from building plan data.

[0023] In the explanation of this embodiment, as an example of a prescribed format, for example, when a building is inspected, an example of inputting information into prescribed fields (input fields) of a basic information input sheet (Form A), which is one of the documents to be submitted to a registered energy conservation assessment body (hereinafter referred to as a registered energy conservation assessment body) in order to receive an energy conservation compliance assessment (building energy consumption performance compliance assessment) from the competent administrative agency or a registered building energy consumption performance assessment body, will be explained.

[0024] FIG. 2 is a diagram showing an outline of a basic information input sheet (Form A) for inputting building-related information acquired by a building-related information acquisition system according to one embodiment of the present invention. The Basic Information Input Sheet (Form A) consists of the 15 input items shown below. 1. Sheet creation date 2. Person in charge of input 3. Building name 4. Building location 5. Energy conservation standard area classification 6. Annual solar radiation area classification 7. Total floor area 8. Uses specified in the attached format of the Building Standards Act Enforcement Regulations (symbols, use classifications) 9. Types of building models applied in the Model Building Law (architectural use, room use) 10.Floor area of ​​the part to be calculated 11. Floor area to be air-conditioned for the calculation target area 12. Number of floors to be calculated 13. Total floor height of the part to be calculated 14.Perimeter of the part to be calculated 15. Non-air-conditioned core part of the calculation target (direction, length)

[0025] The building-related information acquisition system 1 acquires at least some of the above-mentioned input items (e.g., 10. to 15.) of the basic information input sheet (Form A) from the drawing data as building-related information. The building-related information acquisition system 1 then inputs the acquired building-related information into predetermined input fields of the basic information input sheet (Form A) and outputs the basic information input sheet (Form A). Note that data for other input fields of the basic information input sheet (Form A) may be entered by the creator, or items that can be acquired from attribute information set in the building-related information acquisition system 1 may be acquired and entered into predetermined input fields.

[0026] FIG. 3 is a block diagram showing the functional configuration of a building-related information acquisition system according to one embodiment of the present invention. As shown in Fig. 3, the building-related information acquisition system 1 basically comprises, as necessary components, an output means 10, an operation means 11, an acquisition means 12, an arrangement means 13, an attribute information setting means 14, a calculation means 15, and a correspondence means 16. Each of these means is realized by hardware such as a computer incorporating a CPU, storage means (ROM, RAM, storage device, etc.) and its peripheral devices, and software such as programs and data for acquiring building-related information that can be read from a storage device by the computer's CPU and executed and processed.

[0027] The output means 10 is a monitor device that displays an operation screen, a display screen for read drawing data, a display screen for acquired building-related information, and a display screen for a basic information input sheet (Form A), and a printer that prints the basic information input sheet (Form A).

[0028] The operation means 11 is composed of a keyboard, a mouse, etc., and is used for various selection operations and input operations.

[0029] The acquisition means 12 is mainly composed of a computer CPU, and acquires, for example, drawing data (e.g., PDF data, etc.) from a designer's terminal (not shown) connected to the building-related information acquisition system 1, and stores the data in a storage means (not shown). In addition, for example, when the building drawing is on paper, the acquisition means 12 reads the building drawing with a scanner, generates drawing data, and stores the data in the storage means.

[0030] Here, the drawing data is a design drawing included in the design documents, for example, a floor plan of each floor, as shown in Fig. 4. If the building has multiple floors, the drawing data may include all floor plans of each floor, or may include only the floor plan of the floor where the calculation target portion is located, which is the target of calculation in the energy conservation compliance assessment. The drawing data may be image data (for example, bitmap data, etc.), or may be vector data in a vector format generated based on image data (by converting the image data) in the acquisition means 12, for example.

[0031] The arrangement means 13 is mainly composed of the CPU of a computer, and arranges objects in the drawing data acquired by the acquisition means 12 based on the operation of the operation means 11 by the user. The user places an object in the drawing data where they want to add attribute information, and adjusts the shape and size of the object to fit the location. The location where they want to add attribute information includes locations where attribute information needs to be added to obtain building-related information.

[0032] An object is a shape that has graphic information for expressing an object in drawing data, such as its position, shape, size, and color, as well as attribute information for the location where the object is placed in the drawing data. In this embodiment, the objects include room objects and line objects.

[0033] Specifically, room objects are objects placed in the drawing data in locations that are air-conditioned rooms, non-air-conditioned rooms, and rooms outside the calculation target. When room objects are distinguished by their location, they are called air-conditioned room objects, non-air-conditioned room objects, and rooms outside the calculation target. These are set using preset information, which will be described later.

[0034] The graphical information of the room object includes the position, shape, and size of the room object placed in the drawing data, and may further include the color of each room object to distinguish between air-conditioned room objects, non-air-conditioned room objects, and room objects not subject to calculation.

[0035] The position of the object is represented by, for example, coordinate information. In this embodiment, the shape of the object is a rectangle, but it may be a basic shape such as a triangle, polygon, or circle, or any shape set by the user. The color of each room object is arbitrary, and for example, by assigning a color set in the attribute information, it becomes possible to distinguish at a glance between air-conditioned rooms, non-air-conditioned rooms, and rooms not included in the calculation in the drawing data, and it is possible to clearly identify air-conditioned rooms, non-air-conditioned rooms, and rooms not included in the calculation in the drawing data. Note that it is desirable for the color of the object to be transparent or semi-transparent so that notations in the drawing data, such as letters and lines, that overlap with the room object can be seen.

[0036] Next, the line objects are specifically objects that are placed at the periphery of the non-air-conditioning core part and the periphery of the building in the drawing data. The graphic information of the line object includes the position and size of the line object placed in the drawing data, and may also include the color of the line object to distinguish between the periphery of the non-air-conditioned core and the periphery of the building. These are set by preset information, which will be described later.

[0037] As with room objects, by assigning a color to the line objects placed in the drawing data, for example, set in attribute information, it becomes possible to distinguish at a glance the perimeter of the non-air-conditioned core part and the perimeter of the building in the drawing data, thereby clarifying the perimeter of the non-air-conditioned core part and the perimeter of the building in the drawing data. In addition, the graphic information of the line object may include the line type (dotted line, double line, dashed line, etc.) and line thickness instead of the color of the line object, and by changing these, the periphery of the non-air-conditioned core and the periphery of the building in the drawing data may be clarified.

[0038] The attribute information of room objects and line objects is information indicating the name and characteristics of the location where the object is placed in the drawing data, and is set by the attribute information setting means 14, which will be described later. The attribute information items are defined in advance for each of the room objects and line objects. Note that, for room objects, the attribute information items may be defined in advance for each of the air-conditioned room objects, non-air-conditioned room objects, and room objects outside the calculation target.

[0039] FIG. 5 is a diagram for explaining an example of an object-arranged drawing in which objects are arranged in drawing data by the above-mentioned arrangement means 13. In FIG. In the example shown in Fig. 5(a), the object placement drawing is a design drawing (for example, a floor plan of a certain floor) as drawing data, in which a square air-conditioned room object R1 is placed in the location (office) that will become the air-conditioned room, and a line object L1 is placed on the side that constitutes the periphery of the building. Also, in the example shown in Fig. 5(b), the object placement drawing is a design drawing as drawing data, in which a line object L2 is placed on the side that constitutes the periphery of the non-air-conditioned core part.

[0040] Returning to FIG. 3, the attribute information setting means 14 is mainly composed of the CPU of the computer, and sets attribute information for objects that can be placed in the drawing data by the placement means 13 based on the user's operation.

[0041] Specifically, when an object that can be placed in drawing data is selected by the placement means 13 based on a user operation, the attribute information setting means 14 displays a screen (hereinafter referred to as an attribute information setting screen), for example a pop-up screen, for setting attribute information for the selected object (hereinafter also referred to as a selected object) based on preset information that has been set in advance for the selected object. Then, when the user inputs attribute information into the pop-up screen, the attribute information setting means 14 sets the input attribute information for the selected object.

[0042] Here, the preset information is information defined for simplifying the setting of attribute information for an object and for normalizing the attribute information to be set, and is defined for each room object and each line object. The building-related information acquisition system 1 stores preset information in the storage means for each type of information to be acquired from the building's drawing data. That is, preset information dedicated to acquiring legal compliance information, real estate information, GX-related information, 3D map information, etc. is stored in the storage means. Furthermore, preset information is stored in the storage means for each of a plurality of predetermined formats for acquiring the above-mentioned various types of information.

[0043] In the following explanation, preset information for acquiring building-related information to be input into predetermined fields of a basic information input sheet, which is one of the sheets for inputting legal compliance information (information necessary for determining energy conservation compliance), will be described.

[0044] The preset information includes multiple types of attribute information, including information to be set for room objects and information to be set for line objects.

[0045] FIG. 6 is a diagram showing an example of preset information and attribute information set in a room object of the building-related information acquisition system according to one embodiment of the present invention. As shown in FIG. 6(a), the preset information of the room object includes the item name of the attribute information, options for the item value associated with the item name, an input method for the item value, and a calculation method for the item value.

[0046] The item name "floor" is defined to be input (selected) from a pull-down menu that displays options for the floor number where the room object is located ("1 to 11" in the example shown in FIG. 6). Note that no calculation formula is set for the item name "floor". Also, the options "1 to 11" are merely examples and are not limiting.

[0047] The item name "Model Name" indicates the use of the building, and is defined to be entered (selected) from a pull-down menu that displays options (in the example shown in Figure 6, "office, hotel, school, hospital, welfare, retail, food and drink, assembly hall, and factory"). Note that no calculation formula is set for the item name "Model Name." Also, the options "office, hotel, school, hospital, welfare, retail, food and drink, assembly hall, and factory" are examples and are not limited to these.

[0048] The item name "Name of Room Not Subject to Calculation" is defined as the option to enter the name of the room not subject to calculation in the energy-saving compliance assessment, including the options "Factory manufacturing room, freezer / refrigerator room, data center, laboratory, etc., mechanical parking lot," and the "Model Name" from the pull-down menu that displays the options. Note that no calculation formula is set for the item name "Name of Room Not Subject to Calculation." Furthermore, the options "Factory manufacturing room, freezer / refrigerator room, data center, laboratory, etc., mechanical parking lot" are examples and are not limited to these. Furthermore, the item name "Name of Room Not Subject to Calculation" is not set as attribute information for air-conditioned room objects or non-air-conditioned room objects, and may therefore only be included in the preset information of the room object not subject to calculation.

[0049] Item name: Floor area (m 2In the item "Floor Area (m)", a formula is defined to automatically calculate the area of ​​the room object, which is the first step to calculate the floor area of ​​the location where the room object is placed. In this embodiment, the room object is rectangular, so Width*Height. 2 )" does not have any item value options.

[0050] The item name "floor height (m)" is defined so that the user can directly input the height of one floor (first floor) where the room object is placed. Note that it may also be defined so that only numerical values ​​can be input.

[0051] Fig. 6(b) shows the attribute information that the user inputs to the attribute information setting screen in accordance with the preset information shown in Fig. 6(a) and that is set for the selected object by the attribute information setting means 14. Note that the selected object is an air-conditioned room object.

[0052] The item name "floor" and the item name "model name" are set to values ​​selected by the user from a pull-down menu displaying options. In this example, since the selected object is an air-conditioned room object, the item name "room name outside calculation target" is not set, and therefore no input is set. In this way, by setting the value selected by the user from a pull-down menu displaying options, it is possible to simplify the user's input and normalize the user's input content.

[0053] In the item name "Floor Area", a calculation formula of the preset information is first set, and then the floor area of ​​the location where the selected object is placed is set, calculated based on the set calculation formula and the size of the selected object by a calculation means described later. The detailed calculation method will be described later. The item name "floor height" is set to a value that the user directly inputs into the attribute information setting screen.

[0054] Furthermore, preset information may be provided for each position where an object is to be placed. Specifically, for example, three types of preset information including the item names of the attribute information shown in FIG. 6(a), options for item values ​​associated with the item names, input methods for the item values, and calculation methods for the item values ​​may be stored in advance in a storage unit: for air-conditioned rooms, non-air-conditioned rooms, and rooms not subject to calculation. In this case, it is desirable that these three types of preset information have attribute information that colors the object in different colors. For example, an object to which preset information for an air-conditioned room is set becomes the above-mentioned air-conditioned room object.

[0055] FIG. 7 is a diagram showing an example of preset information and attribute information set for a line object in the building-related information acquisition system according to one embodiment of the present invention. As with the room object, the preset information of the line object includes the item name of the attribute information, the item value options associated with the item name, the method for inputting the item value, and the method for calculating the item value, as shown in Figure 7(a).

[0056] The item name "orientation" is defined as having the option of "north, south, east, west" for the orientation of the line object, and the option to enter the orientation from a pull-down menu that displays the option. Note that no calculation formula is set for the item name "orientation." The item name "Length (m)" defines a formula for automatically extracting the length of a line object, for example, a formula for extracting the Length of a line object. Note that no item value options are set for the item name "Length (m)".

[0057] The item name "Line Type" defines that the line object type options are "Outer perimeter, Unconditioned core" and that the "Line Type" is entered from a pull-down menu that displays the options. Note that no calculation formula is set for the item name "Line Type." Furthermore, the "Outer perimeter" in "Line Type" refers to the perimeter of the building, and the "Unconditioned core" refers to the perimeter of the unconditioned core.

[0058] FIG. 7(b) shows the attribute information that the user inputs into the attribute information setting screen in accordance with the preset information shown in FIG. 7(a) and that the attribute information setting means 14 sets for the selected object. The item names "orientation" and "line type" are set with values ​​selected by the user from a pull-down menu that displays options. The item name "Length (m)" is first set with a calculation formula from the preset information, and then the length of the area where the selected object is placed is set using the calculation means described below, calculated based on the set calculation formula and the size of the object.

[0059] Furthermore, preset information may be provided for each position where an object is to be placed. Specifically, for example, two types of preset information, one for a non-air-conditioning core part and one for a perimeter length, including the item names of the attribute information shown in FIG. 7(a), options for item values ​​associated with the item names, a method for inputting the item values, and a method for calculating the item values, may be stored in advance in a storage unit. In this case, it is desirable that these two types of preset information have attribute information that color the object in different colors.

[0060] Returning to Fig. 3, the calculation means 15 is mainly composed of the CPU of the computer, and calculates the floor area and length of the location where the object is placed based on the size of the object that can be placed in the drawing data by the placement means 13 and the attribute information set for the object by the attribute information setting means 14, and calculates building-related information based on these. The building-related information includes the air-conditioned floor area of ​​the building in the drawing data, the perimeter length of the building, and the perimeter length of the unair-conditioned core part of the building.

[0061] Specifically, for a room object, the calculation means 15 calculates the floor area of ​​the location where the room object is placed from a calculation formula set in the attribute information of the room object and a numerical value representing the size of the room object, such as the length of the room object's sides used in the calculation formula and the scale of the architectural drawing on which the room object is placed.

[0062] In this embodiment, since the room object is rectangular, the calculation means 15 measures and obtains the width and height required by the calculation formula set in the attribute information from the location where the room object is placed, and calculates the area of ​​the room object using the calculation formula. The calculated area of ​​the room object is then divided by the scale of the architectural drawing to calculate the floor area of ​​the location where the room object is placed. The scale of the architectural drawing may be input by the user each time, or may be set in advance to the scale of a general drawing.

[0063] In addition, if the floor area is indicated at the location where the room object is placed in the drawing data, the indicated floor area may be used as the floor area of ​​the location where the room object is placed. This eliminates the need to adjust the shape or size of the object when placing it, simplifying the placement of the object. In addition, the calculated floor area may be compared with the indicated floor area, and the comparison result may be notified to the user, allowing the user to select which one to set as attribute information. This prevents calculation errors.

[0064] Furthermore, if there are dimensions parallel to the width and / or height of the room object and for the same length as the width and / or height, those dimensions may be acquired as the width and / or height and calculated as the floor area of ​​the location where the room object is placed. This eliminates errors that may occur due to scale. The acquired dimensions as the width and / or height may also be compared with the length acquired by measuring the room object, and the comparison result may be notified to the user.

[0065] For a line object, the calculation means 15 calculates the length of the location where the line object is placed by dividing the measured length of the line object by the scale of the drawing data. Note that if a dimension is described for a location parallel to the line object and has the same length as the line object, that dimension may be acquired as the length of the location where the line object is placed.

[0066] In addition, the calculation means 15 adds up the floor areas of the locations where each air-conditioning room object placed in the drawing data is placed, calculated using the method described above, and calculates the air-conditioning floor area of ​​the building in the drawing data.

[0067] The calculation means 15 measures and acquires the lengths of the portions where the line objects whose line type is "perimeter" are placed, sums up the acquired lengths, and divides the sum by the scale of the drawing data to calculate the perimeter length of the building in the drawing data. Note that the measured lengths may be summed up after being divided by the scale of the architectural drawing.

[0068] Similarly, the calculation means 15 measures and obtains the lengths of the locations where line objects whose line type is "non-air-conditioned core part" are placed, sums up the obtained lengths, and divides the sum by the scale of the drawing data to calculate the length of the perimeter of the non-air-conditioned core part of the building in the drawing data. In addition, the calculation means 15 identifies the "orientation" set in the attribute information of the longest line object among the line objects whose line type is "non-air-conditioned core part".

[0069] Furthermore, when room objects are set for all rooms in the drawing data, the calculation means 15 can calculate the total floor area of ​​the building in the drawing data based on the sizes of the air-conditioned room and non-air-conditioned room objects.

[0070] The association means 16 associates the items of construction-related information calculated by the calculation means 15 with the item names of the basic information input sheet (Form A) shown in Fig. 2. Then, the association means 16 inputs the calculated values ​​of the construction-related information into the input fields of the associated item names in the basic information input sheet (Form A) prepared in advance.

[0071] Specifically, the association means 16 associates the air-conditioned floor area of ​​the building-related information with the "11. Air-conditioned floor area of ​​the calculation target portion [m 2 ]" and "11. Air-conditioned floor area of ​​the calculation target part [m 2 ]" and enter the calculated value in the input field.

[0072] The correspondence means 16 corresponds the perimeter length of the building in the building-related information to "14. Perimeter length [m] of the part to be calculated" on the basic information input sheet shown in Figure 2, and inputs the calculated value into the input field for "14. Perimeter length [m] of the part to be calculated." The association means 16 associates the outer periphery length of the non-air-conditioned core part of the building and the orientation of the longest side of the non-air-conditioned core part in the building-related information with "15. Length [m] of the non-air-conditioned core part of the part to be calculated" on the basic information input sheet shown in Figure 2, and enters the calculated value in the "Length [m]" input field of "15. Length [m] of the non-air-conditioned core part of the part to be calculated" and the specified orientation in the "Orientation" input field.

[0073] In addition, the association means 16 associates the "model name" set as attribute information of the air conditioning object with "9. Type of building model to be applied in the model building law (architectural use)" on the basic information input sheet shown in Figure 2, and enters the "model name" in the input field for "architectural use" of "9. Type of building model to be applied in the model building law."

[0074] Next, the flow of the construction-related information acquisition process executed by the construction-related information acquisition system 1 will be described with reference to Fig. 8. This construction-related information acquisition process executes a series of steps mainly by the CPU of a computer executing a program for acquiring construction-related information. FIG. 8 is a diagram for explaining the flow of the construction-related information acquisition process executed by the construction-related information acquisition system according to one embodiment of the present invention.

[0075] In step S1, the acquisition means 12 acquires drawing data (see, for example, FIG. 4) of a building for which construction-related information is to be acquired. In step S2, the placement means 13 places an object on the drawing data acquired in step S1 based on the user's operation. In step S3, the attribute information setting means 14 sets, based on the user's operation, attribute information of the location where the object is placed in the drawing data in step S2. In step S4, the calculation means 15 calculates building-related information such as the floor area and perimeter of a predetermined location based on the size of the object placed in step S2 and the attribute information of the object set in step S3. In step 5, the association means 16 outputs an output screen or a printed document that outputs a basic information input sheet (Form A) created by inputting the construction-related information calculated in step S5 into the input fields of the corresponding items on the basic information input sheet (Form A) shown in Figure 2.

[0076] In addition, the above-mentioned construction-related information acquisition process is realized by the computer's CPU executing a program for acquiring construction-related information, which causes each means to function, and by executing processing related to a series of steps.

[0077] According to this type of building-related information acquisition system 1, by placing objects on various types of drawing data and setting attribute information for the objects, attribute information can be added to the drawing data, and building-related information, which is information related to buildings, can be calculated from the drawing data.

[0078] Furthermore, since the building-related information acquired is the input content of the basic information input sheet (Form A) used for determining energy-saving compliance, the building-related information acquisition system 1 makes it possible to create the basic information input sheet (Form A) used for determining energy-saving compliance from various types of drawing data. Furthermore, when calculating building-related information, which is information related to a building, from drawing data, the dimensions indicated in the drawing data are used, thereby simplifying the placement of objects.

[0079] Although the embodiments of the present invention have been described above, it goes without saying that the technical scope of the present invention is not limited to the contents of the above embodiments. It will be apparent to those skilled in the art that various modifications and improvements can be made to the above embodiments. Furthermore, it is clear from the claims that such modifications and improvements are also included within the technical scope of the present invention. [Explanation of symbols]
