Carbon emission measurement and evaluation of large public buildings in the materialization stage.

• This study focuses on the materialization stage of large public buildings to unlock the carbon reduction potential of this stage. • The Life Cycle Assessment is a basic theory. Analytic Network Process and Fuzzy Comprehensive Evaluation combined method were used for carbon measurement and evaluation, and Super Decision is used to assist with calculations. • The materialization stage in large public buildings shows a "Good" carbon grade, while the building materials production stage, which shows an "Average" grade, has the most significant reduction potential. • Research expands carbon modeling for large public buildings, providing a framework for effective regulation during the materialization stage. The greenhouse gas emission during its materialization stage is characterized by time-concentrated and large emissions. This study first divided the materialization stage into three segments according to the life cycle theory: building materials production, building materials transportation, and construction. A carbon emission measurement model for the materialization stage of large public buildings was established by integrating the carbon emission coefficient method, and the emission reduction rate (ERR) was proposed as an indicator for quantitatively assessing carbon emissions during the materialization stage of large public buildings. After the initial indicator system was framed, the Analytic Network Process and Fuzzy Comprehensive Evaluation methods were used to establish the evaluation model for large public buildings at the materialization stage. Last, the model was verified at a convention and exhibition center in Xiamen, China, and it shows that the production stage of building materials has a large potential for emission reduction.
