ABSTRACT
With the growing severity of global water resource shortages, rainwater harvesting and greywater reuse systems in green buildings have become one of the key strategies for achieving sustainable development. This study aims to explore and optimize the integrated design methods of rainwater harvesting and greywater reuse systems in green buildings, and to verify their feasibility and benefits through practical case studies. Based on relevant technical standards and theoretical foundations both domestically and internationally, and incorporating the concept of the building’s entire life cycle, an integrated design fr amework is proposed that organically combines the processes of rainwater collection, treatment, storage, and greywater reuse, while also considering the economic viability and environmental friendliness of system operation. A mathematical model was constructed to predict rainwater collection volumes and greywater demand under different climatic conditions, and a multi-ob jective optimization algorithm was employed to determine the optimal system configuration. At the practical level, a typical green building project was selected as a demonstration engineering case, where detailed design and implementation of the rainwater harvesting and greywater reuse system were carried out. Monitoring data revealed that the system achieved an average annual water-saving rate exceeding 40%, significantly reducing the building's reliance on municipal water supply. Furthermore, this study evaluated the economic benefits and environmental impacts of the system, with results indicating that compared to traditional water supply methods, this system demonstrates clear advantages in reducing carbon emissions and lowering operational costs. The innovation of this research lies in the first-time proposal of a system optimization design method based on dynamic demand matching, successfully achieving efficient synergistic utilization of rainwater resources and greywater reuse. This provides new ideas and technical support for water resource management in the field of green buildings. The research outcomes not only contribute to the advancement of green building technologies but also offer significant references for sustainable urban water resource utilization.
