Of the building components (for example, buildings, equipment, landscapes, etc.), the LCCO ₂ emissions of the buildings are about 10% of the LCCO ₂ emissions of the entire building, but are not negligible. It is desirable to appropriately evaluate the LCCO ₂ emissions of the chassis in each phase of basic design and implementation design and reflect them in the structural design and construction plan.

  However, the environmental performance evaluation system of Non-Patent Document 1 comprehensively evaluates the environmental performance of a building by evaluating various factors such as indoor environment (sound environment, thermal environment, etc.), functionality, and durability. There are very few evaluation items related to the chassis. That is, even if an attempt is made to evaluate the environmental performance of the chassis using the environmental performance evaluation system of Non-Patent Document 1, there is a possibility that the design specifications applied to the chassis cannot be reflected in the evaluation.

Further, in Patent Document 1, the LCCO ₂ emission amount is calculated by multiplying the quantity of members (materials) used in the casing by the basic unit. However, when the LCCO ₂ emission amount is calculated by paying attention only to the quantity, For example, there is a problem that the effect of extending the life of the housing, the effect of adopting an environment-friendly structure, and the like cannot be reflected.

  From this point of view, the present invention is an environmental performance evaluation system for a chassis used for evaluating the environmental performance of the chassis, and the design specifications applied to the chassis can be reflected in the evaluation of the environmental performance. Another object of the present invention is to provide an environmental performance evaluation system for a cabinet, and further to provide an environmental performance index calculation program for calculating an index for evaluating the environmental performance of the chassis.

The environmental performance evaluation system according to the present invention that solves the above-mentioned problems is applied to “a carbon dioxide emission basic unit of a material that may be used for a housing”, “a useful life according to a use of a building”, and “a housing. Storage means for storing “environmental consideration score of design specifications that may be applied”, “quantity of materials used for evaluation target enclosure for which environmental performance is to be evaluated”, “use of building related to said evaluation target enclosure ”And“ design specifications to be applied to the evaluation target enclosure ”, the carbon dioxide emission basic unit a _i stored in the storage unit, and the material input via the input unit Multiply the quantity b _i to calculate the carbon dioxide emission m _i (= a _i × b _i ) for each of the plurality of materials, and add them to obtain the total emission M (= Σm _i ). Total emission calculation means to calculate The useful life D corresponding to the application input via the input means is extracted from the storage means, and the reciprocal of the extracted useful life D is multiplied by the total emission M to obtain the annual emission Y ( = M / D) annual emission calculation means for calculating, and environmental consideration score x _j corresponding to the design specification inputted via the input means is extracted from the storage means, and the extracted environmental consideration score x _The total score calculation means for calculating the total score X (= Σx _j ) by summing _j and the reciprocal of the annual emission amount Y and the total score X are multiplied to obtain the environmental judgment value V (= X / Y). And an environment judgment value calculating means for calculating.

  In short, the present invention is an environmental performance evaluation system used for evaluating the environmental performance of a skeleton (enclosure) among skeleton (enclosure) and infill (interior and equipment) constituting a building, By inputting the “quantity of materials used for the chassis”, “use of building” and “design specifications applied to the chassis to be evaluated”, an index (= environment judgment value) correlated with environmental performance is calculated. .

  The environmental performance of the enclosure to be evaluated depends on whether or not environmentally friendly design specifications have been adopted. Since the environmental judgment value is obtained by using the environmental consideration score (numerical value indicating the degree of environmental consideration) defined for each design specification, if the environmental judgment value is used as an evaluation standard for environmental performance evaluation, The contents of the design specifications can be reflected in the evaluation of environmental performance. If the target value of the environmental judgment value is set in advance, it is possible to evaluate the environmental performance with easy-to-understand indicators such as “rating” and “target achievement”.

  In addition, the data that should be entered at the minimum when calculating the environmental judgment values are “quantity of materials used for the evaluation target enclosure”, “use of building”, and “design specifications applied to the evaluation target enclosure”. Since such data can be grasped from the stage of the basic plan, the environmental performance evaluation system according to the present invention can also be used when making the basic plan. That is, according to the present invention, environmental performance can be easily and objectively evaluated not only at the basic design and implementation design stages but also at the basic planning stage.

The “carbon dioxide emission basic unit” is a kind of environmental load basic unit and is a term meaning “amount of carbon dioxide emitted when producing one unit of material”. For example, “the carbon dioxide emission basic unit of concrete is A (kg / m ³ )” means that “A (kg) of carbon dioxide is discharged when producing 1 (m ³ ) of concrete” Means that.

  The design specifications are contents (for example, material type, construction method, design method, reference value, etc.) to be observed in the design. There are no restrictions on the types of design specifications that should be given environmental considerations, but design specifications that are expected to affect environmental performance (for example, design specifications that contribute to longer life, design specifications that contribute to resource saving, and reuse) Environmentally friendly scores for design specifications related to (reuse), design specifications related to recycling (recycling), design specifications related to variability in use, design specifications that affect the quality of living, etc. Is desirable.

When it is desired to calculate an environmental judgment value that more accurately reflects the characteristics of the use and the structure type, the “correction coefficient corresponding to the use of the building and the structure type of the frame” is stored in the storage means, and the correction is performed. The environment determination value may be corrected with a coefficient. In this case, the environment determination calculation unit extracts the correction coefficient K corresponding to the application and the structure type input via the input unit from the storage unit, and extracts the extracted correction coefficient K and the annual emission amount Y. Is multiplied by the total score X to calculate the environment judgment value V (= K × X / Y).
The environmental performance evaluation system according to the present invention may further include an evaluation sheet creating unit. In this case, the storage means stores a reference annual emission amount that is an annual emission amount of carbon dioxide in a standard enclosure, and the annual emission calculation means is the reference annual emission amount from the storage means. Extracting the amount, calculating a reduction rate of the annual emission amount relative to the reference annual emission amount, the total score calculating means calculating a CO ₂ consideration score by summing a plurality of types of the environmental consideration scores , The evaluation sheet creation means draws an environmental load evaluation chart with one of the reduction rate and the CO ₂ consideration score as the horizontal axis and the other as the vertical axis.

  The environmental performance index calculation program according to the present invention that solves the above-described problems is obtained by using a computer, the storage unit, the input unit, the total emission calculation unit, the annual emission calculation unit, the total score calculation unit, and the environment determination. It is an environmental performance index calculation program for functioning as a value calculation means.

  According to the present invention, it is possible to reflect the contents of the design specifications applied to the evaluation target enclosure in the evaluation of environmental performance. Further, according to the present invention, it is possible to easily and objectively evaluate the environmental performance of the evaluation target enclosure in any of the phases of basic planning, basic design, and implementation design.

For example, as shown in FIG. 15 (a), the evaluation score for each measure displayed in the evaluation score display fields 77a to 77e (see FIG. 14) is a graph. (The illustrated one is a radar chart).

  Further, as shown in FIG. 15B, the breakdown of evaluation scores for each countermeasure may be displayed on a graph. In FIG. 15B, the breakdown of the habitability evaluation score is displayed on the radar chart. The breakdown of the evaluation score for habitability is the total of environmentally friendly scores for the design specifications with “○” in the design specifications belonging to “6.1 Weight impact sound” in the design specification input form shown in FIG. Among the design specifications belonging to “6.2 Vertical vibration”, the total of environmentally-friendly scores of the design specifications marked with “○”, and among the design specifications belonging to “6.3 Wind habitability”, “○ ”Of the design specifications with“ ”and the total environmental consideration scores of the design specifications with“ ○ ”among the design specifications belonging to“ 6.4 Floor acceleration during earthquake ”, and“ 6 .5 Business Continuity ”is the total of environmentally friendly scores for design specifications with“ ○ ”.

  Further, in the present embodiment, the case where the environmental determination value V is calculated as an index for evaluating the environmental performance is exemplified, but it goes without saying that other evaluation indexes may be calculated.

For example, when the annual emission amount Y ₀ of carbon dioxide in a standard enclosure (hereinafter referred to as “reference annual emission amount Y ₀ ”) is stored in the storage means 1 in advance, the annual emission amount calculation means 32 In addition, a function of calculating a reduction rate R (= (Y / Y ₀ −1) × 100%) of carbon dioxide emission may be provided. The reduction rate R is stored in the result file 15. If the reduction rate R is seen, it can be objectively evaluated whether it is a housing which considered the reduction of the carbon dioxide emission amount.

In addition, the total score for the function to calculate the “CO ₂ consideration score”, which is the total of “long life evaluation score”, “resource saving evaluation score”, “reuse evaluation score”, “recycling evaluation score” and “variability evaluation score” While being provided in the calculation means 33, the evaluation sheet creation means 35 may be provided with a function of drawing an environmental load evaluation chart for evaluating the environmental load. The CO ₂ consideration score is stored in the result file 15.

As shown in FIG. 16, the environmental load evaluation chart is such that one of the reduction rate R and the CO ₂ consideration score is on the horizontal axis and the other is on the vertical axis. The environmental load evaluation chart is divided into a plurality of areas (five in FIG. 16). Since each area corresponds to “levels 1 to 5” of the environmental load, “points (marks)” corresponding to the reduction rate R and the CO ₂ consideration score of the evaluation target enclosure are plotted on the environmental load evaluation chart. It is possible to rate the environmental load level of the evaluation target enclosure. In this case, the evaluation sheet creation means 35 reads the reduction rate R and the CO ₂ consideration score from the result file 15, extracts the environmental load evaluation chart, and the rate of reduction of the evaluation target enclosure on the environmental load evaluation chart. A process of plotting points 81 corresponding to R and CO ₂ consideration scores is performed. In the “rating” in the environmental load evaluation chart of FIG. 16, the level “5” is the highest evaluation (that is, the environmental load is small), and the level “1” is the lowest evaluation ( In other words, it means that the environmental load is large.) The classification of the areas may be set as appropriate according to statistical data and empirical rules.

  Furthermore, the evaluation sheet creating means 35 may be provided with a function of drawing an eco-efficiency evaluation chart for evaluating the eco-efficiency of a building.
