Integrated Green Construction Technology System and Performance Evaluation for Urban Building Engineering toward Carbon Neutrality

Abstract

Driven by the national carbon neutrality strategy, the transformation of construction practices toward green development has accelerated; however, the current application of green construction technologies remains fragmented, weakly integrated, and insufficiently quantified in terms of environmental performance. This study constructs an integrated green construction technology system that combines low-energy-consumption material substitution, reusable formwork systems, dynamic carbon-emission monitoring during construction, construction waste recycling, and prefabricated building methods. A performance evaluation index is established through a life-cycle assessment (LCA) framework and carbon-emission accounting model. The results indicate that the proposed system significantly reduces energy consumption, carbon emissions, and material waste throughout the construction phase. The research provides theoretical support and engineering guidance for advancing green construction from policy orientation to systematic technological integration and evidence-based evaluation.
