Decarbonizing the built environment through extensive green renovation requires a carbon footprint of deconstruction/renovation activities, which includes the carbon footprint of materials and components and a holistic approach. High-precision live digital twin models (DTMs) could integrate data repositories and provide a platform for scenario analysis, but standards and maturity are lacking. This project defines a model-building and application strategy, analyzes the requirements for standardizing renovation DTs by creating a digital building product passport and urban-scale DTs through open MIBSIG integration, automating the processes for generating renovation alternatives and their evaluation, combined with life-cycle cost and life-cycle analyses, integrated into DTs, with methods for calculating deconstruction and recoverability scores for renovation deployed by DT standards.
