[0122] In order to conduct a more comprehensive and reasonable evaluation of green and low-carbon buildings, this application comprehensively considers subjective weights and objective weights to weight the evaluation indicators.

[0123] Wherein, step S102 is a method for calculating the subjective weight. The embodiment of the present application can comprehensively utilize the Analytic Hierarchy Process (AHP) and the multi-person evaluation method to calculate the subjective weight of each evaluation index.

[0124] The process of calculating the subjective weight of the evaluation index may include: first, for each evaluation dimension, calculating multiple single-person evaluation weights; then, combining the above multiple single-person evaluation weights to obtain the multi-person evaluation weight of each evaluation dimension; finally, for each evaluation indicator, setting its subjective weight to the multi-person evaluation weight of the evaluation dimension corresponding to the evaluation indicator multiplied by the indicator value of the evaluation indicator.

[0125] In the embodiment of the present application, the above-mentioned single-person evaluation weight can be calculated using the AHP algorithm. Specifically, the above-mentioned step of calculating the single-person evaluation weight may include: obtaining the importance of each evaluation indicator according to the single-person evaluation; determining the importance of any evaluation dimension relative to other evaluation dimensions according to the importance. ij , and establish the judgment matrix A; calculate the eigenvector according to the following formula; W = [W 1 ,W 2 ,…,W n ] T ; W represents the feature vector, W 1 ,W 2 ,…,W n is the weight value of the evaluation dimension, n represents the number of the evaluation dimensions, where, Calculate the maximum eigenvalue corresponding to the eigenvector according to the following formula; (AW) i represents the i-th element of the matrix product AW; in response to the maximum characteristic root satisfying AW = λ max W, the weight value of the evaluation dimension is subjected to consistency check. The calculation can be terminated after the above weight value passes the consistency check, and the calculation is recalculated if it does not meet the consistency check.

[0126] The consistency check may include the following steps: calculating the consistency index f of the judgment matrix CI , f c1 =(λ max -n)(n-1); find the consistency index f of the corresponding matrix order based on the average consistency index RI ; Calculate the random consistency ratio f CR , if f CR<0.1, the judgment matrix is ​​considered to have ideal consistency, otherwise the judgment matrix is ​​adjusted to pass the consistency test. The consistency ratio calculation formula is f CR =f c1 / f R1 .

[0127] The above judgment matrix can be calculated by the following steps: obtain the expert score of each evaluation dimension according to the expert questionnaire score; use a ij Indicates the importance of any evaluation dimension relative to other evaluation dimensions, a ij >0,a ij =1 / a ji , a ii =1; according to a ij Construct a judgment matrix.

[0128] Among them, a ij The importance level is obtained according to the scoring criteria in Table 3.

[0134] The comprehensive weight of step S104 of the present application may be the product of the objective weight and the subjective weight. It should be noted that the sum of the comprehensive weights of all evaluation indicators should be 1.

[0135] The comprehensive score of step S105 of the present application can be determined by multiplying the comprehensive weight by the index value. The calculation formula of the index value can be: S i=(1-number of problem records / total number of records)*100.

[0136] According to the above content, the embodiment of the present application also divides green and low-carbon buildings into 4 levels:

[0137] Basic, one-star, two-star, three-star. Based on the rating range, the classification criteria are as follows:

[0138] When all control item requirements are met, the score is S>50, and the green building grade should be basic;

[0139] When all control item requirements are met, the score is S>70, and the green building grade should be one star;

[0140] When all control item requirements are met, the score is S>90, and the green building grade should be two stars;

[0141] When all control item requirements are met, the score is S>95 and the green building grade should be three stars.

In the case of such a distributed scenario, one of the multiple devices can only perform one or more steps in the method of one or more embodiments of the present application, and the multiple devices will interact with each other to complete the described method.
