Description

  The present invention relates to a deterioration simulation system for exterior materials that predicts the degradation of exterior materials that are members facing the outside, such as outer wall materials and roof materials, in houses and other buildings.

  Exterior materials such as outer wall materials in buildings deteriorate due to the effects of solar heat, moisture, ultraviolet rays, etc., and the coating color changes over time. The diagnosis of color deterioration is performed, for example, by measuring a physical quantity such as Lab after aging and a physical quantity such as Lab of the base color member with a color difference meter and obtaining a color difference ΔE between the two. This ΔE is set to 6 or more by the US National Bureau of Standards, “a sense of color difference is large”. In Patent Document 1, regarding the coating of the outer wall, the color change with time according to the accelerated weather resistance test is referred to as a “deterioration prediction line”. In this regard, the current degree of deterioration is obtained by overlapping the color difference ΔE in the actual property. In addition, ΔE = 6 is set as the lifetime of the outer wall, and a method of displaying the time (maintenance time) when the lifetime is reached from both is considered. At the same time, maintenance costs are being calculated.

JP 2011-99707 A

  Even for exterior materials with the same specifications, the degree of deterioration varies depending on the amount of solar heat, moisture, ultraviolet rays, etc., and these vary depending on the weather conditions in each region. Moreover, the specifications of a building such as a house are different depending on the region, and the difference in the building specification is a difference in solar heat and moisture applied to the outer wall material, which also causes a difference in the degree of deterioration depending on the region. In the prior art, the degree of progress of deterioration due to such areas is not taken into consideration, and appropriate deterioration cannot be predicted.

  Further, the color difference ΔE is a general index indicating a color difference in terms of engineering, but it is an expression that is not familiar to ordinary people. Therefore, there is a problem that it is difficult to determine the degree of deterioration even if the threshold value ΔE = 6 is indicated. Furthermore, in the prior art, the degree of deterioration after maintenance corresponding to the maintenance specification is not displayed, and it is impossible to know how the deterioration proceeds by performing what kind of maintenance.

An object of the present invention is to provide an exterior material deterioration simulation system capable of appropriately predicting deterioration of an exterior material according to a region.
Another object of the present invention is to show the degree of deterioration in an easy-to-understand manner to ordinary residents.
Still another object of the present invention is to make it easy to select a maintenance specification by predicting and displaying deterioration due to the maintenance specification for a plurality of types of maintenance specifications.

The exterior material deterioration simulation system (1) according to the present invention includes:
For each region, a linear curve deterioration curve (a) indicating the relationship between the degree of color deterioration due to deterioration of exterior materials and the aging , the horizontal axis indicating the age of building, and the vertical axis indicating the degree of color deterioration was determined. Regional aging storage means (2),
Building data using exterior materials to be simulated, for example, basic information input means (3) for inputting and storing information for determining the address and age of the construction site;
Color actual measurement value input means (4) for storing information on the color actual measurement values of the exterior material to be simulated,
Color deterioration calculation means (5) for obtaining the degree of color deterioration from the color actual measurement values stored in the color actual measurement value input means (4);
From the building data stored in the basic information input means (3), an area defined in the local aging deterioration storage means (2) is specified, the deterioration curve (a) is selected, and the deterioration curve (a) Is obtained from the degree of deterioration obtained by the color deterioration calculation means (5) and information for determining the building age in the building data stored in the basic information input means (3), and the current point after the current point is calculated. A deterioration predicting means (6) that uses the portion of the deterioration curve (a) as a prediction result of deterioration;
Ru equipped with.
The exterior material is a member facing the outdoors in a house or other building, and may be an outer wall material or a roof material. The regional aging deterioration storage means (2) may be provided separately for each type of exterior material.

  According to this configuration, the deterioration curve (a) indicating the relationship between the degree of deterioration of the exterior material and the aging is determined for each region, and the deterioration curve (a) for each region is selected from the building data to predict deterioration. Use. Therefore, it is possible to appropriately predict the deterioration of the exterior material according to the difference in conditions due to the difference in area.

The basic information input means (3) has an item for inputting a survey date on which the deterioration of the exterior material was actually measured. The actual color measurement value input means receives and stores the actual color measurement values of a portion where the progress of color deterioration of the exterior material of the survey date input to the basic information input means is small and a portion where the progress is large, and The color deterioration calculation means (5) is configured to obtain the degree of color deterioration from the difference in the degree of deterioration between the portion where the color deterioration is not progressing and the portion where the progress is progressing.
The exterior material is shaded or the like, so that there are a part with little color deterioration and a part with much color deterioration depending on the part, and there are parts where the deterioration hardly progresses even after several years. For this reason, the degree of color degradation can be obtained from the difference in the degree of degradation between the portion with little color degradation and the portion with much color degradation. If a new sample of the exterior material or a numerical value of a new color is already known, it is possible to know a more appropriate current state of deterioration by determining the deterioration as the new color information. However, there are few cases where such new samples and color data remain, and even if they remain, it is difficult to specify which type of exterior material is available and which type is present. For this reason, by determining the degree of deterioration from the color difference between the part with little color deterioration and the part with much color deterioration, any exterior material of any property can be easily and appropriately deteriorated to some extent. Can be predicted. For this reason, for example, even if the exterior material deterioration prediction is performed as one item of the building periodic diagnosis, the prediction can be easily performed, and the exterior material deterioration prediction is incorporated into the building periodic diagnosis item. Can be realized.
Further, the color deterioration calculating means (5) obtains the degree of color deterioration of the exterior material only from the difference in L value indicating the lightness in the color Lab display system.
Among the numerical values L, a, and b indicating the difference in color, the numerical value L of the lightness of the color is dominant as a numerical value indicating the degree of deterioration. Accordingly, the degree of deterioration of the exterior material can be easily and appropriately obtained by obtaining the degree of deterioration of the color of the exterior material from the change in the value of L indicating brightness.

In the deterioration simulation system (1) according to the present invention, the prediction result of the deterioration predicting means (7) is displayed as the color of the exterior material separately at the time of new construction, present and future, that is, the set number of years elapsed from the present. Basic prediction result display means (7) may be provided.
Unlike the case where the color difference is indicated by numerical values, by displaying the color of the exterior material at the time of new construction, the current time, and the set elapsed years as a predicted result of deterioration, the general owner such as the owner can also feel the degree of deterioration Can be easily understood.

In the deterioration simulation system (1) according to the present invention, the deterioration curve (a) stored in the regional aging deterioration storage means (2) indicates the difference between the climate for each region and the specifications of the building constructed for each region. It may be a deterioration curve (a) created by reflecting the above.
The climate greatly affects the degree of deterioration of the exterior materials and varies from region to region. In addition, building specifications tend to vary from region to region due to differences in climate, etc., and building specifications such as the outer wall insulation layer and ventilation structure greatly affect the deterioration of the outer wall exterior material. Therefore, taking into account the use of these climates and buildings, a deterioration curve showing the relationship between the degree of color deterioration and aging is established and stored, so that the prediction of deterioration of exterior materials can be made more in accordance with the region. It can be done more appropriately.

The exterior material degradation simulation system of the present invention shows the relationship between the degree of color degradation due to exterior material degradation and aging for each region, the age on the horizontal axis, and the degree of color degradation on the vertical axis. A local-year degradation storage means for determining a deterioration curve of a secondary curve, basic information input means for storing information for determining building data using exterior materials to be simulated, and exteriors to be simulated Color actual value input means for inputting and storing information on the actual color value of the material, color deterioration calculation means for determining the degree of color degradation from the actual color value stored in the actual color value input means, and the basic information Before selecting the deterioration curve from the building data stored in the input means and specifying the area defined in the regional aging deterioration storage means, and obtaining the current point in the deterioration curve by the color deterioration calculation means Determined from the information defining the age of the stored building data on the degree of deterioration and the basic information input unit, and a degradation prediction means to predict the result of deterioration of the part of the degradation curve of the subsequent current point, the The basic information input means has an item for inputting a survey date on which the deterioration of the exterior material was actually measured, and the actual color measurement value input means is a color of the exterior material on the survey date input to the basic information input means. The actual color measurement values of the portion where the progress of deterioration of the color is low and the portion where the progress is high are input and stored, and the color deterioration calculation means determines the color deterioration based on the difference in the degree of deterioration between the low color deterioration portion and the high color deterioration portion.

It is a relational chart showing the relationship between the degree of deterioration of the system and aging. It is a figure which shows the prediction result of the future color change of the system. It is a graph which shows the prediction of the deterioration accompanying the aging for every maintenance specification of the system.

  An embodiment of the present invention will be described with reference to the drawings. This exterior material deterioration simulation system 1 is a system for predicting exterior material deterioration in a house or other building, and is schematically shown in FIG. 2 in an information processing apparatus 1A (including an operation program) such as a personal computer. By installing the deterioration simulation program shown, each function achievement means shown as a block in FIG. 1 is configured. The information processing apparatus 1A only needs to function as a computer, and may be a multi-function mobile phone called a smartphone, or a portable information terminal in a tablet format or other formats. The deterioration simulation program can be executed by a computer. The information processing apparatus 1 </ b> A is provided with an input device 11, an image display device 12 such as a liquid crystal display device as an output device, and a printer 13 in or away from the housing. The input device 11 is a device such as a keyboard, a mouse, or a touch panel, or an external input terminal or an input terminal of a portable storage element.

  As shown in FIG. 1, this deterioration simulation system 1 includes a regional aging deterioration storage means 2, basic information input means 3, color actual value input means 4, color deterioration calculation means 5, deterioration prediction means 6, and basic prediction result display means. 7. A maintenance specification deterioration storage unit 8 and a maintenance specification prediction display unit 9 are provided, and a report creation unit 10 is further provided.

  The regional aging deterioration storage means 2 is a means for determining a deterioration curve indicating the relationship between the degree of color deterioration due to deterioration of the exterior material and the aging for each region, and includes a map 2a and a graph 2b. The degree of degradation depends on the climate of each region. For this reason, a map 2a and a graph 2b that relatively indicate the degree of deterioration are prepared in advance, and the deterioration level at the input construction site is determined. As shown in FIG. 5, the map 2a is, for example, a map of Japan, which is divided into regions with the same deterioration level, which is the degree of ease of exterior material deterioration, and is color-coded. Has address information (not shown) included in the category. In this example, the region is divided into seven stages of deterioration levels I to VII.

The graph 2b is represented by a deterioration curve a in which the horizontal axis indicates the age of the building and the vertical axis indicates the degree of color deterioration. The deterioration curve a is, for example, a linear curve (inclined straight line). In this case, the inclination of the deterioration curve a is stored as data of the graph 2b. The graph of the deterioration curve a is provided for each type of exterior material used, that is, for each type such as whether the exterior material is an outer wall or a roof. The map 2a may be common to the respective types of exterior materials, or may be different for each type. The deterioration curve a is created, for example, by reflecting the difference between the climate for each region and the specifications of the building constructed for each region. Differences in building specifications include cross-sectional structures such as outer walls and roofs, materials for each layer of the cross-section, uses of the room in which the exterior material of the building is used, and differences in living schedules. As the difference in building specifications, all the above items may be reflected, or some of them may be reflected, for example, only the cross-sectional structure and material of the outer wall.
In this case, for example, from the results of various accelerated deterioration tests conducted so far, a deterioration curve a as shown in FIG. 6 based on the lightness L is prepared in advance for each deterioration level. Is specified, the deterioration line a corresponding to the deterioration level at the construction site can be determined.

The basic information input means 3 is means for inputting and storing building data using an exterior material to be simulated, for example, information for determining the address and age of a construction site. The basic information input means 3 includes an input processing unit 3a and a storage unit 3b. The input processing unit 3a outputs a basic information input screen as shown in FIG. 3 to the image display device 12 and should input it. The item is displayed to prompt the input, and the input data is stored in the storage unit 3b. Items to be entered on this input screen include, for example, the name of the customer who is the owner of the building to be simulated, the address of the construction site, and the age of the building (the date of delivery of the building, the survey date on which the exterior material was actually measured) It is. When all items have been input and the software key displayed as “completed” is turned on, the input processing unit 3a stores the input items in the storage unit 3b.
When providing the graph of the deterioration curve a for a plurality of types of exterior materials in the regional aged deterioration storage means 2, for example, the basic information input means 3 or the like is made to input selection of the type of exterior material to be simulated. The graph of the degradation curve a corresponding to the type can be selected from the input type information. When the degradation simulation system 1 is dedicated to the simulation of a fixed exterior material such as an outer wall material or a roof material, it is not necessary to input the selection of the exterior material type.

The actual color measurement value input unit 4 is a unit that inputs and stores the actual measurement value of the color of the exterior material, and includes an input processing unit 4a and a storage unit 4b. The input processing unit 4a outputs a color actual value input screen shown in FIG. 4 as an example to the image display device 12, and inputs each of a portion where the color deterioration of the exterior material is small and a portion where the color deterioration is large. The part with less color degradation is a non-sunlight surface, and the part with a large color deterioration is a solar radiation surface. The numerical values of the colors are, for example, numerical values of R (red), G (green), and B (blue) of the RGB display of the color. The input processing unit 4a enters the numerical values of the input units on the input screens, and turns on the software keys labeled “OK” to store the input numerical values in the storage unit 4b.
The input processing unit 4a of the actual color measurement value input means 4 may have a function of reproducing the color indicated by the numerical value of the input color in a part of the color actual value input screen or a part aligned with this screen. preferable.

The color deterioration calculation unit 5 is a unit that obtains the degree of color deterioration from the color actual measurement value stored in the color actual color value input unit 4. The color degradation calculation means 5 obtains the degree of color degradation from the difference in the actual color measurement values between the portion where the progress of the color degradation is small and the portion where the progression is large . Further, the color deterioration calculation means 5 converts the numerical value of the color input in the RGB display into the Lab display system, and changes in the L value indicating the lightness in the converted Lab display system, that is, the color deterioration. The degree of deterioration of the color of the exterior material is obtained from the brightness difference between the small portion and the large portion. In this case, the relationship between the brightness difference and the degree of deterioration of the exterior material is obtained and stored as a relation curve or function by a test or the like, and the degree of deterioration is calculated from the brightness difference.

  The degradation predicting means 6 selects the degradation curve a by specifying the area defined in the regional aging degradation storage means 2 from the address of the construction site in the building data stored in the basic information input means 3, Which position of the selected deterioration curve is the current point is determined from the degree of deterioration obtained by the color deterioration calculating means 5 and the delivery date and investigation date information stored in the basic information input means 3, The portion of the deterioration curve after the current point is set as a deterioration prediction result. In this case, the building age is from the date of delivery to the date of survey.

  Specifically, the deterioration predicting means 6 specifies the region in the map 2a of FIG. 5 from the address of the construction site and determines the deterioration level of the region, and as shown in FIG. 6, the slope corresponding to the deterioration level is determined. A deterioration curve a is obtained. The building age is defined as the value on the horizontal axis, the degree of color deterioration (such as the brightness difference) as the value on the vertical axis, and the intersection (shown with an asterisk in the figure) is defined as the current point. The deterioration prediction from the current point can be performed by moving the deterioration curve a so that it passes through the current point.

  The basic prediction result display means 7 displays the prediction result of the deterioration prediction means 6 in the format shown in FIG. 7, for example, at the time of setting elapsed from the time of new construction, the present, and the current future (in the figure, five years). The color of the exterior material is displayed on an output device such as the image display device 12 or the printer 13 separately. The basic prediction result display means 7 may display the map 2a shown in FIG. 5 on a screen or the like to indicate which deterioration level the construction site corresponds to.

  The maintenance specification degradation storage unit 8 is a unit that stores a plurality of types of maintenance specifications of the exterior material and relationship information for predicting the degree of degradation associated with aging for each type. The maintenance specifications include, for example, top coating of a chromatic color paint on the exterior material, top coating of a transparent paint, repainting of the entire coating film layer, and the like.

  The prediction display unit 9 for each maintenance specification stores the relationship information of the prediction of the degree of deterioration with the lapse of time for each maintenance specification of the exterior material stored in the deterioration storage unit 8 for each maintenance specification, such as the image display device 12 or the printer 13. Means for displaying on the output device. For example, as shown in FIG. 8, the horizontal axis represents the number of years elapsed from the present time, and the vertical axis represents the degree of color degradation (such as a difference in brightness) for each plan (ie, each maintenance specification). Display as a curve.

  The report creation means 10 is a means for creating a report in which results of periodic building inspections, for example, 10-year inspections, etc. are written in a predetermined format. As a part of the report to be created, the basic prediction result display The prediction result by the means 7 and the prediction result by the maintenance specification prediction display means 9 are described. Although it is necessary to input items used in the report creation means 10 other than these prediction results, the description thereof is omitted here.

  Next, the flowchart of FIG. 2 will be described. This figure is a flowchart showing each procedure of the deterioration simulation. The numbers in circles in the figure correspond to the items marked with () below.

In FIG. 2, in step S1, the basic information input screen G1 of FIG. 3 is displayed on the image display device 12, prompting the user to input the construction site address, delivery date, and survey date. When the operation of ("Done" key is turned on) is performed, the input items are stored.
Step S2 is a step of determining whether or not to use a digital camera for color information calculation. This embodiment is an embodiment in the case of using a digital camera, and step S2 is not a procedure for configuring this deterioration simulation program, but a procedure for inputting a determination result as to whether or not to use this digital camera. In addition to the deterioration simulation program, the color numerical value input screen may be different.

When using a digital camera, output the screen G2 (Fig. 4) for entering the actual measured values of the parts of the exterior material where color degradation is low and the actual measured values of the degraded parts. When input processing indicating completion of input ("OK" key is turned on) is performed, those numerical values are stored (step S3).
In this case, for photographs of exterior materials such as outer walls on solar and non-sunlight surfaces taken with a digital camera, color measurement values within a specified range using a personal computer using image processing software different from this deterioration simulation system (For example, RGB values) are obtained. The calculated actual color value is input to the input field of the input screen G2 as shown in FIG. The input color actual measurement value is reproduced, that is, displayed on the screen as shown in FIG. Such a function of displaying the color from the actual color measurement value is provided in commercially available spreadsheet software or the like, and the actual color measurement value input means 4 in FIG. Is displayed. The color measurement value of the non-sunlight surface may be used for calculation by the color deterioration calculation means 5 (FIG. 1) as the color at the time of new construction, and the color measurement value of the solar radiation surface as the current color. A color difference meter can be used by inputting a Lab value and converting it to RGB. Processing in that case will be described next.

In step S2, when the digital camera is not used, the processing of steps S10 to S12 is performed, although it is another embodiment. That is, a color difference meter is used to calculate color information ((step S10) (this step is not a step included in the deterioration simulation program)). When a color difference meter is used, Lab of exterior materials such as outer walls on the solar and non-sun surfaces can be obtained. Therefore, in the color measurement value input screen G2 (FIG. 4), the Lab values on the solar and non-sun surfaces are input. When a numerical value is input and input processing indicating completion of input is performed in the same manner as described above, the numerical value is stored. In this case, the color actual measurement value input means 4 has a procedure for converting the Lab value into the RGB value in Step S12, and stores the RGB value after the conversion.
Note that the Lab value obtained in step S11 may be stored in the actual color measurement value input means 4 without providing the conversion procedure in step S12, and the process may proceed from step S11 to step S4.

When the actual color measurement value is input as described above, the building age is calculated using the difference between the stored delivery date and the survey date as the building age (step S4). Specifically, the building age is calculated as follows: Age = (Consecutive days from the survey date to the delivery date) / 365.
Thereafter, the area classified according to the degree of deterioration is searched from the address of the construction site, and a deterioration curve a indicating the degree of progress of the deterioration of the construction site is determined (step S5). In this case, as shown in step S13, the map 2a of FIG. 5 is used, and the relationship diagram showing the relationship between the degree of deterioration and aging in FIG. 6 is used.

In step S6, the difference of the numerical value of the color of a part with little deterioration (non-sunlight surface) and a part with much (sunlight surface) is calculated, and this is used as the quantified degree of current deterioration. As for the degree of deterioration, the RGB value is converted into the Lab value, and the degree of deterioration is obtained from the difference in the L value indicating the lightness in the Lab value. Based on this value and the building age determined as described above, the current point is plotted and displayed in the graph of FIG. 6, for example, as indicated by an asterisk in the same figure (step S14).
When the Lab value obtained in Step S11 is stored and used without performing the conversion process in Step 12, the conversion from the RGB value to the Lab value in Step S14 is unnecessary, and the stored Lab value is used. This is used to calculate the degree of deterioration in step S6.

In step S7, the future change is calculated from the degree of deterioration obtained in step 6. In this case, since the most dominant element as the color change is lightness, the a value and the b value may not be considered due to changes over time, and are not considered in this embodiment. The future lightness L and the Lab value based on the current a value and b value are converted into RGB values (step 15).
The calculation result of step S7 is reproduced as shown in FIG. 7 (step S8). At this time, the future color is reproduced from the RGB values using the color setting function of the spreadsheet software, and the color is reproduced as shown in FIG. Each color of the newly constructed, current, and future (after 5 years and 10 years) may be displayed side by side on the same screen for comparison, or may be displayed by switching the screen.
Thereafter, a graph or a list showing the relationship between the maintenance specification and the deterioration is displayed (step S19).

According to this embodiment, as described above, the deterioration curve a indicating the relationship between the degree of deterioration of the exterior material and the aging is determined for each region, and the deterioration curve a for each region is selected from the address of the construction site, Used to predict deterioration. Therefore, it is possible to appropriately predict the deterioration of the exterior material according to the difference in conditions due to the difference in area.
Further, the color deterioration calculating means 5 obtains the degree of color deterioration from the difference in the degree of deterioration between the portion with little color deterioration and the portion with much color deterioration. A part with little deterioration and a part with many deterioration occur, and there are places where the deterioration hardly progresses even after several years. Therefore, the degree of color deterioration can be obtained from the difference in the degree of deterioration between the portion with little color deterioration and the portion with much color deterioration. If a new sample of the exterior material or a numerical value of a new color is known, the current state of deterioration can be known more appropriately by using the known information as new color information for determination of deterioration. However, there are few cases where such new samples and color data remain, and even if they remain, it is difficult to specify which type of exterior material is available and which type is present. For this reason, by determining the degree of deterioration from the color difference between the part with little color deterioration and the part with much color deterioration, any exterior material of any property can be easily and appropriately deteriorated to some extent. Can be predicted. For this reason, for example, even if the exterior material deterioration prediction is performed as one item of the building periodic diagnosis, the prediction can be easily performed, and the exterior material deterioration prediction is incorporated into the building periodic diagnosis item. Can be realized.

Since the basic prediction result display means 7 displays and indicates the color of the exterior material at the time of new construction, the current time, and the set elapsed years as shown in FIG. 7 and FIG. Unlike the case where the numerical values are indicated, general owners such as owners can understand the degree of deterioration as an actual feeling.
The maintenance specification prediction display means 9 shows the prediction result of the degree of deterioration for each maintenance specification as shown in FIG. 8, so that the maintenance specification, that is, which plan is selected and how the deterioration progresses can be known. This can be done by helping to select specifications.

The color deterioration calculating means 5 obtains the degree of color deterioration of the exterior material from the change in the L value indicating the lightness in the color Lab display system. Of the numerical values L, a, and b indicating the color difference, the color deterioration calculating means 5 calculates the color deterioration degree. The lightness value L is dominant as a value indicating the degree of deterioration. Therefore, the degree of deterioration can be easily and appropriately obtained by obtaining the degree of color deterioration of the exterior material only from the difference in the L value indicating the lightness.

  In this embodiment, the deterioration curve a stored in the regional aging deterioration storage means 2 is created by reflecting the climate of each region and the specification of the building constructed for each region as described above. It is a deterioration curve. The climate greatly affects the degree of deterioration of the exterior materials and varies from region to region. In addition, building specifications tend to vary from region to region due to differences in climate, etc., and building specifications such as the outer wall insulation layer and ventilation structure greatly affect the deterioration of the outer wall exterior material. Therefore, taking into account the use of these climates and buildings, a deterioration curve showing the relationship between the degree of color deterioration and aging is established and stored, so that the prediction of deterioration of exterior materials can be made more in accordance with the region. It can be done more appropriately.

The effects of this embodiment are summarized below.
