Description

Technical Field

[0001] This application relates to the field of integrated and three-dimensional design of buildings and cities, and in particular to an integrated-three-dimensional design platform and method for the carbon reduction effect of buildings and cities. Background Technology

[0002] Building urban design and carbon sequestration assessment primarily rely on two traditional models: separate design and assessment, and experience-driven three-dimensional design. These models are costly and prone to significant assessment errors. To promote collaboration between building design and carbon sequestration assessment, the industry has gradually introduced information technology, resulting in two main improvement schemes, but significant limitations still exist.

[0003] Single-function carbon assessment software: Software focused on building carbon sink calculations has emerged on the market, capable of importing partial building design data for carbon index measurement. However, its limitations are as follows: First, poor compatibility, supporting only data formats from a few mainstream design software programs, insufficient support for commonly used design tools, and inability to directly access macro-level data such as land use types and POI distribution from urban geographic information systems, resulting in an assessment scope limited to single buildings and difficulty in achieving integrated building-city carbon assessment; Second, lack of real-time interaction, requiring offline calculations after design data is fixed, and the inability to adjust design parameters in real time based on carbon sink results, resulting in low collaborative efficiency between design and assessment.

[0004] Basic GIS visualization platforms: Some urban planning platforms have 3D map rendering and spatial data display functions, which can present information such as building outlines and land use layout. However, these platforms have obvious shortcomings in carbon sink collaborative design: First, they lack a carbon sink estimation module, and cannot calculate carbon sinks based on building spatial indicators, but can only provide a visual presentation of spatial form; second, their design parameter control capabilities are weak, and users cannot adjust parameters such as vertical greening rate and building height through convenient interactive methods such as sliders, nor can they achieve linkage feedback between parameter adjustment and carbon sink results, making it difficult to meet the need for real-time balance between "design technology application - carbon index assessment".

[0005] In summary, there is an urgent need for an integrated, three-dimensional design platform for the carbon reduction effect of buildings in cities, meeting the following core requirements: First, to achieve data collaboration, breaking down data barriers between design software, GIS systems, and carbon assessment tools, and supporting standardized access and sharing of multi-source urban spatial data; second, to achieve real-time interaction, establishing a dynamic linkage mechanism between design parameters and carbon sink results, allowing users to easily adjust parameters and view carbon sink changes in real time, achieving synchronous optimization of "design-assessment"; and third, to possess integrated functions, integrating modules such as data acquisition, parameter control, carbon sink estimation, and three-dimensional visualization feedback, forming a technical platform covering the entire process of "data input-design adjustment-carbon sink assessment-result display," meeting the real-time balance needs of "design technology application-carbon index assessment" in scenarios such as urban renewal and carbon neutrality pilot projects. Summary of the Invention

The design technology effectiveness evaluation and output module is used to determine the carbon reduction and carbon sink potential of buildings and regional transportation based on building and land use attribute data, and to map the overall carbon reduction potential classification, the regional building function hybrid carbon reduction level, and the regional road land carbon reduction level, respectively.

[0075] In the design technology effectiveness evaluation and output module, the executing entity is the computer-based carbon sequestration assessment subsystem. Its connection is to receive design technology application data from the design technology application type selection and control module. Processing content includes:

[0078] The carbon reduction of green travel coordination planning technology in urban areas is determined by using the technical formula.

[0079] The carbon sequestration of vertical greening design technology for buildings in urban areas is determined using the formula for such design.

[0080] The carbon reduction amount of the mixed-use building carbon reduction technology in a neighborhood is determined using the formula for carbon reduction technology based on the mixed-use building functions in a neighborhood.

[0083] Building layers are rendered based on the overall carbon reduction potential classification and the priority of three-dimensional carbon sink mapping.

[0084] The technical formula for the coordinated planning of green travel in the neighborhood is:

[0085] TCE = (VTA / TA) .

[0086] Among them, TCE is the carbon reduction of the green travel coordination planning technology in the block; VTA is the green travel road area; TA is the total road area; and α1 is the carbon reduction coefficient of the three-dimensional traffic design technology.

[0087] The formula for the vertical greening design technology of the street buildings is as follows:
