AI Technical Summary
Existing methods for calculating building carbon emissions suffer from high data requirements, slow calculation speed, and insufficient applicability. They are particularly difficult to provide effective guidance when data is missing or incomplete. Furthermore, existing methods cannot effectively integrate the strong inherent correlation between building materials, transportation, and construction processes.
By collecting full data from multiple historical building projects, key building materials were identified, and a carbon emission calculation method based on a linear regression model was constructed. Using Pearson correlation coefficient, variance expansion factor, and construction energy consumption coupling influence index, a quantitative relationship between building material consumption and total physical carbon emissions was established, enabling rapid calculation.
It enables accurate calculation of total emissions without requiring comprehensive monitoring of all auxiliary materials and construction facilities data, reducing the difficulty of data collection, providing a scientific basis for decision-making, and supporting low-carbon management and dynamic control in the construction industry.
