Description

BIM-based decoration mode environment assessment method and device

Technical Field

The application relates to the technical field of building information model application, in particular to a decoration mode environmental assessment method and device based on BIM.

Background

China in the 21 st century is actively promoting the development of green buildings, energy-saving buildings and environment-friendly buildings. The green building emphasizes the concept of the whole life cycle from the stages of design, construction, operation and maintenance, and requires the building to achieve the purposes of energy conservation, land conservation, water conservation, material conservation and environmental protection, and to achieve the purposes of health, comfort and high efficiency. From the building perspective, the full life cycle concept itself includes the finishing stage of the building during construction. With the continuous deepening of the building greening and sustainable development theory, the concept of green building decoration is gradually introduced from green buildings, and the building becomes a new thinking and a new direction of the decoration industry. However, in view of the current market situation, the decoration industry has the current situations of relative dispersion and uneven levels, and the introduction of the green concept makes the 'greening' development of the industry more easily confused. In addition, while the government managers actively promote the development of green buildings, the government managers also pay attention to the guidance of related industries such as architectural decoration, but the development will have a certain lag. From the development perspective of the architectural decoration industry, the lack of related policies and management systems can also bring certain negative effects to the benign development of the whole architectural industry and market. Therefore, development of economical, low-carbon and environment-friendly green building decoration becomes a consensus of the industry, is a development trend of the building decoration industry, is also a necessary choice for building a resource-saving and environment-friendly society, converting a development mode and promoting scientific development of the industry.

BIM, Building Information Modeling, Building Information model, has been widely used in the construction, engineering, and construction industries to accommodate efficient collaboration among multiple design process participants. BIM provides a collaboration platform to facilitate information exchange and sharing among professional design participants to achieve better decisions. A decoration model system established by BIM related software subverts the traditional thinking mode, and all contents of the whole project including all professional departments can be presented in the system, namely the decoration model system is a platform for resource communication, and all information related to the project can be searched in the model. Utilize the setting of 3D information model, can promote operating mass with rated load in the decoration field, reduce problem and rework number of times. At present, building units do not pay attention to the application of BIM in the decoration stage, although some standards and specifications related to BIM have been established and widely popularized in China, a considerable part of developers and manufacturers only regard modeling as a surface project and do not realize specific functions and effects. The research on the BIM mostly focuses on some links of research such as concept, theory and management, and a breakthrough is still needed in aspects of comprehensively utilizing a building information model, considering the influence of multiple evaluation factors of green buildings and the like.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

First, a decoration BIM integrated management system to which the present application is applied will be described, please refer to a schematic diagram of functional module configuration shown in fig. 1.

As shown in fig. 1, the decoration BIM integrated management system includes a decoration design information collection and storage module, a decoration design information classification module, a decoration design information and building environment information expression module, a BIM architecture integration module, and a critique analysis module.

Based on the above functional modules, the following will describe the usage and implementation of the functional modules with reference to the flowchart shown in fig. 2:

referring to fig. 2, fig. 2 is a flowchart of a decoration method evaluation method applied to a decoration BIM integrated management system according to an embodiment of the present application, including the following steps:

s101: collecting and storing actual decoration design information of a target building through a design information collecting and storing module;

the specific way of designing the information acquisition and storage module to realize the purpose of the step can be as follows:

collecting actual decoration design information according to a standard checking method, a data checking algorithm or a model analysis method;

the actual finishing design information is described and stored using structured data and unstructured data.

The standard approval method is to approve related standards and specifications by combining with an information model according to different project requirements, transmit related information from design, specifications, components, processes, products and the like to the information model, collect and perform approval, and finally perform feedback through corresponding information, which can be seen in the following table 1:

TABLE 1 Activity level data acquisition

The data core algorithm starts with the material and influence index of the design information model, and the information possibly involves various stages through inputting the model, so that a corresponding data list is obtained, and actual possible attribute information is reserved. Data accounting is considered from the design, construction, recovery and environmental impact stages, and quantity information of different projects is input and accounted, which can be seen in table 2 below:

table 2 project output data information at different stages

The model analysis method combines information related to each component, material, equipment and the like in the information model through the information and can be used for simulation, thereby providing a basis for evaluation. The data information that different indexes need to be input and output is shown in table 3:

TABLE 3 design model input output data information

Meanwhile, in order to store the collected data, structured data and unstructured data can be adopted for description according to different file formats and data standards in the storage process and the requirements of actual description: the public data described by the standard storage belongs to the structured data, is the core of the BIM, and can be directly analyzed and stored in the database; the unstructured data comprises document information, tables, graphic information and the like which are related to projects, and the model information can be expressed through a file format of professional software or an IFC standard file format.

Furthermore, the information sharing and interaction can be realized by pre-establishing a design-related data information public data and resource library. Meanwhile, related information can be set as design information and auxiliary data, the design information is main model information, the related data is presented as related auxiliary results, and auxiliary support data such as template files or external reference libraries are provided. One specific expression form can be seen in a BIM data organization form diagram shown in FIG. 3, a data storage center is established, internal data in different fields and different specialties are combined for organization, and a shared data area is formulated for other fields to access; secondly, authority distribution is carried out through an access mechanism to guarantee safe data access; meanwhile, corresponding organization storage mechanisms are established for structured data and unstructured data.

S102: classifying the actual decoration design information through a decoration design information classification module to obtain classified design information;

before classification, the actual decoration design information can be further subdivided into classification in an acquisition processing process and classification in an information output process, and the two parts can conform to the same preset information classification principle.

The classification of the information acquisition and processing process can be classified according to the source mode of the information, and can be mainly divided into the following steps: geometric dimension information (derived from the design solution model and automatically obtained through the model), design input data (additional information required to be input after the basic solution design is completed);

the classification of the information output process can be classified according to corresponding evaluation three-level indexes, and in this case, the minimum granularity of the information at the bottommost layer of the database is data corresponding to the third-level indexes;

the information classification principle is that the BIM carries out information classification according to the characteristics of engineering projects, and specifically comprises the following four forms:

construction → part → material;

construction → part → material;

construction → part → construction → material;

building → part → component → technology.

For ease of understanding, one of the forms is chosen here for hierarchical presentation: an office (building) comprising a ceiling, a floor, and a wall (three main locations), wherein the ceiling employs a gypsum board suspended ceiling decoration scheme (component), the gypsum board suspended ceiling base employs a 38-keel suspended ceiling, the facing employs a 600X600 gypsum board (construction), the gypsum board employs 25mm thick surfacing materials (materials), and the construction and installation of the base and facing is a process.

Fig. 4 is a schematic diagram illustrating an exemplary implementation of classification of design information, which sets a room library, a component product library, a material library, a process library, a product information library (classified into two types, i.e., energy consumption and non-energy consumption), an air quality information library, a design specification information library, and the like to implement different classifications of design information.

S103: expressing the classified design information and the corresponding building environment information through a decoration design information and building environment information expression module to obtain expressed information;

for easy understanding, the implementation process of the step can be further decomposed into expressions of six parts, namely, design information component relation, building component material, geometry, attribute information, building equipment and information component and building environment influence information, wherein:

design information component relational expression by using IFC (Industry Foundation Classes, through IFC, in the whole life cycle of the building project promote communication, productivity, time, cost and quality, for the process in the global building and equipment profession promote the information sharing establishes a universal standard), EXPRESS (information modeling language, is the core of product model data exchange standard ISO 10303, provides a neutral mechanism, can be connected with various programming environments) description mode to EXPRESS the interrelation of different component entities, and carries out the expression of design related information.

The IFC expresses design objects, the attributes of the objects and the interrelations by using the concepts of the EXPRESS language and classes as a whole. And the interaction and sharing of the design model information among different analysis software are realized by combining the open data interaction standard of the BIM design information model. In the concrete information expression, the contents of possible components, materials, equipment and the like of the building decoration are combined and coded aiming at the information expression, so that the BIM information expression in the building decoration is realized, as shown in the following table 4:

TABLE 4 model component naming conventions

Building element material information expression is carried out by relating the incidence relation of the IFC and the building entity element information; the building geometry information expression is expressed by two modes of product description (IFC production replication) and relative coordinates (IFC Local Placement) in the IFC standard. Including information such as Product Shape description (IFC Product Representation Shape), Shape model (IFC Shape), and item description (ifcreepresentation). The detailed description is expressed by item description (IFC Representation). Relative coordinates (IFC Local Placement) express the position of the entire model in the coordinate system; the building Element attribute information expression is associated with building environment influence evaluation, the influence of design model information on the building environment influence evaluation is comprehensively expressed, and the building environment influence evaluation is described in two modes of primitive Quantity (IFC Element Quantity) and attribute information definition; the building equipment and the information Component expression are expressed by adopting an abstract entity of a primitive (IFC Element), and a pipeline distribution primitive (DistributionElement), an Electrical primitive (IFC Electrical Element) and a connection primitive (IFC Element) are added on the basis, so that the equipment and the system composition are comprehensively described.

The building environment influence information is an important data base for building environment evaluation. The building environment influence information expression includes component information, component attribute information, component geometry information, material information, equipment and system information, and the like. The data information of each part forms different information sources of the environment evaluation in a correlation mode.

S104: integrating the expressed information according to a preset BIM architecture level through a BIM architecture integration module to obtain integrated information;

the BIM model designed by the application is provided with a data layer, a model layer, a network layer and an application layer, so that the expressed information is layered and integrated according to the data layer, the model layer, the network layer and the application layer which are included by the BIM structure. Wherein:

the IFC of the data layer is an effective mode of BIM information, can realize the information description of an object model, and establish a relational database through a relational model to finish data structure recording and data information storage;

the model layer realizes the reading, storage, extraction, integration, verification and other work of IFC model data through a BIM information integration platform;

the network layer is built based on a network and a communication protocol, the working modes of different participants of a construction project are supported, and data interaction and access of the different participants are realized through a wide area network or a local area network;

the application layer is composed of application software in different stages, and the software comprises software applications in different stages in the whole life cycle of the construction project engineering, such as planning design, building design, structural design, construction management, property management and the like.

Based on the above, fig. 5 shows an actual schematic diagram of integrating the expressed data into a four-layer model.

S105: analyzing the integration information by combining a preset critique rule through a critique analysis module to obtain a critique analysis result;

on the basis of the steps, the integrated information is analyzed item by item from energy, material, water, space utilization and air quality according to the corresponding environmental assessment requirements, so that the final environmental assessment analysis result is obtained. Wherein, the environmental assessment requirements are extracted based on a frame of 'Green building evaluation Standard'.

The process of analysis can be seen in a schematic diagram shown in fig. 6, and the items of energy, materials, water, space utilization and air quality are docked one by one aiming at the decoration project, so that further refinement of evaluation of the green building project is better realized. And based on data information extraction, conversion, calculation and integration of each stage, green degree evaluation of decoration and fitment design is realized.

S106: and determining whether the evaluation of the current design scheme reaches the standard or not according to the evaluation result.

One approach to meet the criteria, including but not limited to passing a score threshold, may be:

extracting an actual environmental evaluation score from the environmental evaluation analysis result;

judging whether the actual environmental assessment score exceeds a preset environmental protection decoration threshold value or not;

if yes, judging that the environmental evaluation of the current design scheme reaches the standard;

if not, judging that the environmental evaluation of the current design scheme does not reach the standard.

Wherein the environmental protection finishing threshold is a pre-calculated environmental rating score, such as 60 or 75 points in percent, that can be used to distinguish environmental compliance from non-compliance. Of course, the judgment of whether the standard can be reached through the environmental evaluation can be made through the number of the standard-reaching items, and the judgment can be flexibly adjusted according to the actual situation and the requirement.

Obviously, on the basis of the traditional BIM model, the information in the design process is structurally defined and classified, and the information of environmental benefit, economy, energy efficiency and the like of different parts in decoration is scientifically and reasonably managed, so that the basis is laid for the management and circulation of the design information of the decoration green evaluation system, the BIM model is expanded and applied to the evaluation aspect related to decoration, the evaluation standard of the actual decoration scheme based on the system is specifically realized, and the reliable analysis result can be quickly and accurately obtained.

Furthermore, if the current design scheme does not reach the standard, the decoration BIM integrated management system can conveniently output the building components influencing the comprehensive score and the corresponding current part design scheme according to the requirements through the functional modules so as to serve as a reminder of targeted improvement, and even can give a reasonable improvement reminder, thereby reducing wrong attempts.

Because the situation is complicated and cannot be illustrated by a list, a person skilled in the art can realize that many examples exist according to the basic method principle provided by the application and the practical situation, and the protection scope of the application should be protected without enough inventive work.
