Carbon Emission Measurement and Analysis of Prefabricated Building Components Based on a Quota Analysis.

To address the problem of cumbersome and unrepresentative collection of activity-related data in the calculation of carbon emissions of prefabricated building components, the calculation method of social average carbon emissions based on quota data is proposed. On this basis, combined with the results of standardization of prefabricated components in China, three calculation methods are proposed based on the availability of data to form a standardized carbon emission database for prefabricated components, which extends the standardization of prefabricated component design to the field of carbon emission calculation. Through calculation and analysis, the equations of the steel content of prefabricated components, the carbon emission ratio of reinforced concrete, and carbon emission per unit volume are obtained. The proposed carbon emission calculation method is more convenient and universal, which can provide references for related research. [ABSTRACT FROM AUTHOR]
