Problems solved by technology

[0008] According to the content of the above application, these existing technologies have a common problem: they cannot be applied to the renovation design of existing buildings, because the renovation of existing buildings is different from new buildings, and the calculation of carbon emissions is more complicated. It is not only necessary to pay attention to the final completion indicators, Carbon emissions will also be generated in the intermediate link, that is, the indicators in the demolition stage should be calculated separately first, then the indicators from the completion of demolition to the completion of renov...

Embodiment 1

[0075] The construction of the BIM model before the renovation of the existing building includes the following steps:

[0076] (1) Import architectural engineering drawings into BIM software, automatically read readable building information such as beams, slabs, columns, walls, pipes, etc., manually input building coordinates, floor heights, and unreadable building information, and perform automatic mold overturning, Build the first BIM model before reconstruction;

[0077] (2) Arrange the sensors according to the geometric features of the building, and use the 3D scanning technology to obtain the real spatial data of the on-site building, that is, the measured point cloud data set of the existing building;

[0078] (3) Interacting the first BIM model and the on-site measured point cloud data set, adjusting the first BIM model to match the point cloud data based on the point cloud data, and establishing the second BIM model before the transformation;

[0079] (4) For the seco...

Embodiment 2

[0083] Calculation of carbon emission indicators for the entire life cycle of existing buildings before and after renovation. Taking the calculation of carbon emission indicators for the entire life cycle of existing buildings after renovation as an example, the automatic calculation of embedded carbon emissions is mainly realized through the secondary development of BIM software, which includes the following steps:

[0084] (1) Carry out step-by-step dismantling of the transformation process according to the building transformation plan, determine the part to be demolished and the new part of the original building after the transformation, and establish the fourth BIM model after the demolition of the building and the fifth BIM model after the transformation respectively;

[0085] (2) Interact the third BIM model with the fourth BIM model for the secondary development of BIM software, compare the BIM models before and after demolition, generate a list of building materials for...

Embodiment 3

[0095] The iterative optimization of the existing building renovation plan based on carbon emission indicators includes the following steps: analyzing whether the carbon emission indicators meet the standards, if not, return to the optimization and renovation steps, continue to optimize the renovation plan, and return to the fourth, fifth, and sixth BIM model building steps , carry out optimization until the carbon emission index calculated according to the renovation plan reaches the standard, and finally determine the existing building renovation plan.

[0096] The optimization scheme of this embodiment is based on multi-parameter dynamic sensitivity analysis to realize constrained nonlinear programming. The carbon emission index is used as the final target parameter, and various design parameters are used as the variables to be optimized. The real-time sensitivity of the variables to be optimized, and then look for the variables that have a greater impact on the carbon emiss...

Abstract

The invention discloses an existing building reconstruction digital design method based on full life cycle carbon emission calculation, and the method takes a digital tool as a carrier, i.e., building information model software and a secondary development plug-in thereof as tools to carry out existing building reconstruction design. According to the method, the reconstruction scheme is evaluated on the basis of the carbon emission index of the whole life cycle of the building, the carbon emission calculation method is embedded in the design process, and the existing building reconstruction scheme with the carbon emission index reaching the standard is finally obtained through repeated iteration, so that the double control of building energy conservation and emission reduction is realized, the digitization level of building reconstruction design is comprehensively improved, and the construction efficiency is improved. The design process is optimized, the design quality is improved, the living environment can be improved, and a high-quality green building can be built.

Description

technical field [0001] The invention belongs to the field of energy-saving renovation of existing buildings, and relates to a digital design method for renovation of existing buildings based on the calculation of carbon emissions in the whole life cycle. Background technique [0002] The energy-saving renovation of existing buildings is an important part of urban renewal, and it has certain requirements for carbon emissions. The carbon emission index after renovation is an important part of renovation design. At present, there is no professional automatic calculation software for building carbon emissions in China. BIM technology The application in the field of carbon emissions of new buildings is not mature enough, and the existing buildings have different indicators before and after renovation. The design and calculation process is more complicated than that of new buildings, and BIM technology is more difficult to apply and implement. [0003] Because the BIM model of the...
