The Sustainability Study and Exploration in the Building Commercial Complex System Based on Life Cycle Assessment (LCA)–Emergy–Carbon Emission Analysis

This paper focuses on the sustainable exploration of building systems, which combines ecological concepts and low-carbon designs for a comprehensive sustainability assessment investigation. The study employed Life Cycle Assessment (LCA)-Emergy (LCA)-Carbon emission methods to discuss range topics, including main contributing factors, index verification, sensitivity analysis, potential improvement measures. From an perspective, results indicate that operation stage plays critical role, accounting approximately 45% entire emergy in commercial complex. (ESI) is 0.354, below standard 1. Moreover, also significantly contributes carbon emissions, particularly 50th anniversary operation. Based these findings, recommends two strategies improve state design involve use renewable energy sink improvement, respectively.
