Technical Field

[0002] As an important part of urban development work, building renovation involves an increasingly wide range of contents and is a comprehensive, overall, policy-based and strategic social system project. There are generally problems such as the loss of original drawings or inaccurate hand-drawn drawings in old buildings, and multiple local renovations during the construction process have not formed a systematic file (such as pipeline renovation, structural adjustment, etc.), resulting in a lack of reliable baseline data support during renovation. In the traditional renovation process, it often relies on manual on-site investigation, which is time-consuming and laborious, and it is difficult to quickly generate a visual basic model. In the design stage, the renovation of existing buildings still mainly focuses on basic repairs, lacking a systematic energy-saving optimization plan, and there are significant shortcomings in data integration and sustainability. Currently, most renovation projects are led by the government or developers, and residents' opinions are collected through one-way channels such as questionnaires, lacking a real-time interaction platform. Moreover, existing technologies have problems such as a lack of digital negotiation tool support, independent operation of each link, and data islands, with low levels of intelligent collaboration and dynamic interaction. In the output stage, traditional technologies are limited to communicating and spreading through drawings or videos, greatly restricting the communication efficiency of all parties and resulting in slow project progress. There is an urgent need to break through the bottleneck of the traditional renovation mode through innovative means such as digital twin technology and intelligent sensor networks. Therefore, combined with the current digital assistance technology requirements for building renovation and urban renewal, systematically sorting out the current general and easy-to-use digital software tools, constructing a new technical path and new work process for easy-to-operate and highly versatile digital information-assisted design and intelligent interaction, and improving work efficiency have important value and significance.
