Study on the Coupling Mechanism and Environmental Benefit Comprehensive Evaluation of Building-Landscape-Energy Systems in Zero-Carbon Campuses

摘要

Against the backdrop of China’s “dual carbon” strategy and high-quality development of higher education, zero-carbon campuses have become a key research focus in green and low-carbon campus construction. Most Chinese universities currently suffer from independent design, separate operation, and poor coordination among building, landscape, and energy systems, which limits carbon reduction and environmental improvement.This paper takes zero-carbon campuses as the research object, explores the coupling mechanism of building‑landscape‑energy systems, and establishes a comprehensive evaluation system covering carbon reduction, microclimate regulation, thermal comfort, energy efficiency, and ecological quality. Using numerical simulation and case analysis, it identifies how multi‑system synergy improves campus environmental performance.Results show that integrated optimization of building energy conservation, ecological landscape design, and clean energy systems can effectively reduce operational energy use and carbon emissions, enhance outdoor thermal environment and comfort, and boost overall campus sustainability. Finally, collaborative optimization strategies for planning, technology, and operation are proposed to support low-carbon campus renovation and the implementation of China’s dual carbon goals.
