Green building life cycle assessment method and system based on pile foundation data

This invention provides a green building life cycle assessment method and system based on pile foundation data. It acquires material and energy consumption data during the construction phase, including pile foundation data, and calculates the building's inherent environmental load by combining this data with an environmental impact factor database. During the service life, it collects pile foundation structural response monitoring data and uses a structure-foundation correlation model to invert and obtain the equivalent load time series of the superstructure reflecting the building's actual usage state. The equivalent load time series is input into a pile foundation performance degradation model to generate a maintenance plan and calculate the maintenance environmental load. Simultaneously, it identifies the building's actual usage mode and calibrates the building energy consumption model to calculate the operational environmental load. Based on the predicted state of the pile foundation performance degradation model at the end of the planned lifespan, it assesses the remaining bearing capacity of the pile foundation, formulates demolition, renovation, or reuse disposal strategies, and calculates the disposal environmental load. Finally, it summarizes the inherent, maintenance, operational, and disposal environmental loads to obtain the building's full life cycle environmental load assessment results.
