AI Technical Summary

Technical Problem

In existing technologies, material flow data and carbon emission calculation models are disconnected, making it difficult to trace the carbon emission contributions of materials or components at each stage of a construction project, which affects refined management and emission reduction applications.

Method used

By constructing a material-component mapping table, generating a spatiotemporal flow sequence of materials, and combining it with a large-scale carbon emission model, carbon emission calculations are performed on each material flow record, including detailed calculations of the building material production, transportation, and construction stages, taking into account factors such as construction progress, transportation routes, and recycling.

Benefits of technology

It enables traceability of carbon emissions on a per-item basis, reflecting the composition and contribution distribution of carbon emissions at each stage of a construction project, improving the accuracy of measurement results and the ability to respond to dynamic changes in construction, and supporting refined management and traceability.

Abstract

The application discloses a kind of carbon emission measurement methods of fusing building project material flow and large model of carbon emission, belong to building carbon emission measurement technical field.For the defect that material flow data and carbon emission calculation model are split in existing measurement, material level measurement cannot be realized, the method is by extracting component list and material procurement list, mapping relationship table is generated by material coding association;From logistics and warehousing system, extract transportation, warehousing and delivery records, and generate material space-time flow sequence according to timestamp alignment, match with mapping relationship table, obtain material flow-component association data;Build carbon emission large model with built-in carbon emission factor database, including production, transportation and construction calculation module;Material flow-component association data is input into model, production carbon emission, transportation carbon emission and construction carbon emission are calculated, and the total cycle carbon emission measurement result is obtained by adding up, for the fine measurement of building project whole cycle carbon emission.
