Discussion

Analysis shows renovation reduces greenhouse gas emissions more than reconstruction, suggesting greater carbon reduction potential.

Renovation achieved a carbon emission intensity of approximately 1.37 × 10^3 kg–CO2eq/m2, reducing emissions by 46.21% compared to existing buildings.
Operational upgrades during renovation led to a 47.50% decrease in emissions through enhancements like insulation and renewable energy systems.
Reconstruction produced higher carbon emissions due to the necessity of new materials and demolition waste, despite some reductions.
Results highlight renovation as a viable strategy for carbon neutrality in the building sector by 2050, supporting design and policy frameworks.
