Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention.

The technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.
The grade evaluation mode of the existing green building takes the national standard 'green building evaluation standard' as the evaluation standard, the design evaluation index of the 'green building evaluation standard' is composed of six national standard large-class indexes of 'land and outdoor environment saving', 'energy saving and energy utilization', 'water saving and water resource utilization', 'material and material resource utilization', 'indoor environment quality' and 'improvement and innovation', and the total number of the national standard measures is 212. The design scheme of the building project participating in the green building certification needs to meet the technical measure combination corresponding to a plurality of 212 national standard measure items, the overall design scheme meets the standard of the corresponding certification level of the green building, the level division is divided into a three-star level, a two-star level, a one-star level and a basic level from high to low, wherein the basic level requirement is that the national standard score of each type is more than or equal to 40 points, and the total national standard scores of the one-star level, the two-star level and the three-star level need to reach 50 points, 60 points and 80 points respectively on the basis of meeting the basic level requirement.
In order to overcome the problem that in the prior art, a designer needs to manually select technical measures from 212 national standard measure items to combine according to design experience so that the designed green building scheme meets the evaluation standard of the corresponding national standard grade, the actual design operation process is complex, the time consumption is long, and the building design efficiency is influenced, the embodiment of the invention provides a system construction method of the green building scheme, and as shown in fig. 1, the system construction method of the green building scheme specifically comprises the following steps:
step S1: acquiring an item scoring result of each national standard measure item performing utility scoring according to item attributes, an item attribute weight result of each item attribute performing weight assignment and an item attribute weight result of each item attribute performing weight assignment according to item attributes, wherein the item attributes comprise: quality, ecology, technical difficulty and cost, and the project attributes include: authentication level, land price, owner type, building type, and item type.
Specifically, when a building item is being subjected to green building authentication, the building item needs to be authenticated according to the item attribute-related information of the building item, for example: the certification level declared by the construction project is one star, two stars or three stars, and the national standard total score required to be met is correspondingly different. In the embodiment of the present invention, the meaning of the item attribute of the building item and the attribute value corresponding thereto are detailed in table 1. In the embodiment of the present invention, a building design scheme with an authentication level of at least star level is taken as an example for description, in practical applications, a basic level green building design scheme may also be implemented by corresponding adjustment with reference to the embodiment of the present invention, and the present invention is not limited thereto.
TABLE 1
In the embodiment of the invention, the item scoring result, the item attribute weight result and the item attribute weight result are obtained by adopting a questionnaire survey and expert opinion collection mode of quantitative measure evaluation of a Likter scale, 0-6 parts of utility assignment is respectively carried out on all national standard measure items in four dimensions according to the expert opinion, the performance of the national standard measure items on quality, ecology, technical difficulty and cost is evaluated, and the item scoring result is obtained, wherein the item scoring result is shown in a table 2; weighting the four item attributes by using an analytic hierarchy process according to the expert opinions to obtain the item attribute weighting result, which is shown in a table 3; according to the expert opinion, the item attributes under different item attributes (authentication level, land price, owner type, building type and item type) are subjected to weight assignment to obtain the item attribute weight results, wherein the weight assignment under each item condition is obtained according to different item conditions, and the item attribute weight results under partial item conditions are shown in a table 4. It should be noted that, in the embodiment of the present invention, the item scoring result, the item attribute weighting result, and the item attribute weighting result are obtained in a manner of collecting expert opinions, in practical applications, other existing models or algorithms may also be used to calculate the item scoring result, the item attribute weighting result, and the item attribute weighting result, which only can implement the functions provided by the embodiment of the present invention, and the present invention is not limited thereto.
TABLE 2
TABLE 3
| Item attributes | Quality (Q) | Ecological (E) | Cost (C) | Technical difficulty (D) |
| Weighted value | 0.33 | 0.31 | 0.20 | 0.16 |
TABLE 4
Step S2: and aiming at each preset project, calculating the feasibility value of each national standard measure item of the preset project according to the project attribute, the item scoring result, the item attribute weighting result and the project attribute weighting result corresponding to the preset project. In practical applications, the practical feasibility of each national standard measure item is different for different preset projects, for example: some reconstruction and extension projects are limited by the influence of the original building design, and when the projects are designed, technical measures corresponding to some national standard measure items can not be actually constructed, so that the feasibility of each national standard measure item needs to be comprehensively evaluated by combining the characteristics of the project, so that the relatively optimal national standard measure item can be conveniently selected for scheme design.
Specifically, in one embodiment, in the step S2, the feasibility value of the national standard measure entry of the preset item is calculated according to the following formula (1):
wherein,
the feasibility value, C, of the national Standard measure item i representing the project ji1、Di1、Qi1、Ei1Item scoring results respectively representing national standard measure items i, Ci2、Di2、Qi2、Ei2Respectively representing item attribute weight results of national standard measure items i, Ci3、Di3、Qi3、Ei3Respectively representing the item attribute weight result of a national standard measure item i, wherein i is a positive integer from 1 to 212, j represents the number of a preset item, and j is a positive integer. In the embodiment of the present invention, the feasibility values of the national standard measure entries under different project conditions are calculated based on the multi-attribute effect theory, for example, the feasibility value of the national standard measure entry 1 in table 2 corresponding to the project condition 1 in table 4 is:
i.e. the feasibility value of national standard measure item 1 under project case 1 is 4.68.
Step S3: and generating a preset green building scheme corresponding to the preset project according to the sorting result of the feasibility values. In practical application, the feasibility values are respectively calculated for all national standard measure items of the preset project according to the formula (1) so as to conveniently select proper national standard measure items subsequently to form a green building scheme.
Specifically, in an embodiment, in the step S3, the step of generating the preset green building plan corresponding to the preset item according to the sorting result of the feasibility values specifically includes the following steps:
step S31: and sequencing the feasibility values of all the national standard measure items according to the national standard large categories, and selecting the national standard measure items in each national standard large category according to the sequence of the feasibility values from high to low until the sum of the scores of the selected national standard measure items reaches a first preset standard value. In practical applications, the first predetermined standard value corresponds to the score standard of the base level in the green building rating scale, and in the embodiment of the present invention, the first predetermined standard value is 40, specifically, taking the item 1 in the above table 4 as an example, the international entries and related information thereof are shown in table 5.
TABLE 5
Step S32: and further carrying out secondary sequencing on the unselected national standard measure items according to the feasibility value, and selecting the national standard measure items again according to the sequence of the feasibility value from high to low until the sum of scores of the selected national standard measure items reaches a second preset standard value, wherein the second preset standard value is larger than the first preset standard value. In practical application, because the embodiment of the present invention mainly aims at the green construction scheme with the star-level standard, the total score of the green construction design scheme needs to be greater than the corresponding score of the corresponding star-level standard under the condition that the score standard of the basic level is met, and the second preset standard value is 50 when the predetermined item needs to be evaluated as a star item; when the preset item needs to be evaluated as a two-star item, the second preset standard value is 60; when the predetermined item needs to be rated as a samsung item, the second predetermined criterion value is 80. Specifically, taking item 1 in table 4 above as an example, the international entries and related information thereof are shown in table 6.
TABLE 6
Step S33: and generating a preset green building scheme according to all the selected national standard measure items. Specifically, as can be seen from table 6, if the authentication type of the preset item is one star, the total score of the first selected item is 41.42 points and exceeds the first preset standard value by 40 points, the score of the second selected item is 8.78 points, the total score of all the items selected twice is 50.2 points, and the result meets the authentication standard of a star-green building, so that the green building scheme generated by combining the technical measures corresponding to the corresponding national standard items in table 6 meets the star-level identification standard of the preset item.
In practical application, by repeatedly executing the steps S31 to S33, the preset green building plan under all the preset project conditions can be obtained, all the preset project information and the preset building plan integrally form the database of the green building plan system, and a data basis is provided for the subsequent generation of the green building plan according to the project conditions.
Step S4: pairing all the preset items pairwise, and respectively calculating the attribute similarity and scheme similarity of the two preset items. Specifically, in the embodiment of the present invention, the database established in step S3 is used to obtain the relevant rule of the green building scheme by comparing the similarity of the preset items in the database with the similarity of the preset green building scheme, so as to facilitate the generation of the subsequent green building scheme.
Specifically, in an embodiment, in the step S4, the calculating the attribute similarity of the two preset items specifically includes the following steps:
step S41: and converting the item attributes corresponding to the two preset items into numerical values according to preset rules. Specifically, in the embodiment of the present invention, an assignment manner is adopted to convert the item attribute into corresponding numerical information, for example, see table 7 in detail, it should be noted that, in practical application, the item attribute may also be subjected to numerical conversion by using other preset rules, and the present invention is not limited thereto.
TABLE 7
Step S42: and respectively carrying out difference on the numerical values corresponding to the attributes of each item in the two preset items to obtain the attribute similarity of the two preset items. Specifically, taking item 1 and item 2 in table 4 as an example, assuming that the actual difference between the prices of the two is 45 ten thousand, the similarity of the attributes is as follows: the S certification rating is 0, the S place price is 45, the S owner is 0, the S building type is 1, and the S item type is 0.
Specifically, in an embodiment, in the step S4, the step of calculating the similarity between the schemes of the two preset items includes the following steps:
step S43: and converting the preset green building schemes corresponding to the two preset projects into item selection vectors. Specifically, in the embodiment of the present invention, taking the preset green building scheme of item case 1 shown in table 6 as an example, all the international entries to be selected are converted into a form of 01 vector, where one entry selection vector has 212 bits in total, and represents 212 international measure entries, where 1 represents an entry to be selected, and 0 represents a drop entry, and then the entry selection vector of item 1 is:
[1 1 1 1 1 1 1 1 0 1 0 1 1 0 0 0 0 0 0 0 0 0 1 1 1 1 0 0 0 0 0 1 1 00 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 00 0 0 0 0 1 0 1 1 1 1 1 1 1 0 0 0 0 0 0 0 0 1 1 0 0 0 0 0 0 1 0 0 0 0 0 0 0 00 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 1 0 0 01 0 1 1 0 0 0 1 0 0 1 1 1 0 0 0 0 0 0 0 1 1 0 0 1 0 0 0 0 0 0 0 0 0 1 0 0 0 00 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0]。
step S44: the scheme similarity is calculated from the item selection vector by the following formula (2):
wherein S isdist(m,n)Indicating the similarity of the preset green building plan corresponding to the item m and the preset green building plan corresponding to the item n,
an item selection vector indicating a preset green building scheme corresponding to the item m,
and expressing an item selection vector of the preset green building scheme corresponding to the item n, wherein T represents the total number of all the preset green building schemes, and m, n and T are positive integers.
