Study on Whole-Life-Cycle Management of Green Building Projects

With the deepening of global sustainable development concepts, green buildings have demonstrated significant value in energy conservation, emission reduction, efficient resource utilization, and environmental friendliness. However, traditional project management often focuses on a single phase and lacks systematic control spanning from planning and design through operation and decommissioning. Based on Life Cycle Management (LCM) theory, this paper constructs a whole-life-cycle management framework covering four stages — planning and design, construction implementation, operation and maintenance, and decommissioning and recycling — and proposes key methods such as target setting, performance monitoring, cost control, and risk management. Through case studies of representative domestic and international green building projects, the effectiveness of the proposed indicator system and management strategies in controlling energy consumption, reducing carbon emissions, and optimizing economic benefits is demonstrated. The study shows that whole-life-cycle management not only enhances the overall performance of green buildings, but also promotes industry standardization and technological innovation, providing decision-making references and practical guidelines for governments, owners, and design-build teams.
