### Practical Significance  
The new theories, methods, and technologies developed in this research will provide foundational support for the design and optimization of zero-carbon architecture in tropical island settings in China. This study not only offers innovative solutions for engineering applications but also holds significant implications for driving the green transformation of the tropical island construction industry and achieving the national dual-carbon strategic goals. The research outcomes will foster technological advancements in the construction industry, promote the widespread adoption of green building practices, and contribute to achieving sustainability objectives. The practical significance of this research can be discussed from three perspectives:  
1. Practical Significance in Engineering Applications of Research Findings: In the unique climatic conditions of tropical islands, zero-carbon architectural design faces challenges such as specific climate environments, a lack of technical systems, and insufficient integrated experiences. This study constructs a theoretical framework and optimization methods for the quantification of energy utilization, energy conservation, energy production, and intelligent systems. It not only improves the energy efficiency of buildings and reduces operational costs but also enhances residents' comfort and health while minimizing negative environmental impacts. The engineering application of these research findings aids in promoting the concept of the zero-carbon architectural technology system and its systematic integration, fostering the application of green building technologies and providing sustainable building solutions for tropical island regions.
2. Practical Significance for the Transformation and Upgrading of the Tropical Island Construction Industry: With the increasing awareness of environmental protection and the widespread adoption of green sustainable development principles, the construction industry faces pressure to transition from traditional building systems to more environmentally friendly and energy conservation approaches. This research provides foundational theories and technical methods to support the transformation and upgrading of the tropical island construction industry. By applying the research outcomes, the construction industry can better adapt to the challenges of the tropical island climate, improve energy utilization efficiency, and reduce carbon emissions, thereby promoting sustainable development in the construction sector. Specifically,for tropical island regions like Hainan, the application of this research will contribute to advancing the modernization of the local construction industry, aligning with the construction goals of the Hainan Free Trade Port as a clean energy hub.
3. Practical Significance for Achieving the National Dual-Carbon Strategic Goals: China has committed to achieving the dual-carbon goals of peak carbon emissions and carbon neutrality. As a significant source of energy consumption and carbon emissions, the construction industry urgently needs a green transformation. The application of this research will facilitate progress in energy efficiency, renewable energy utilization, and intelligent energy management in the construction industry. Implementing the theory and practice of zero-carbon architecture in tropical island buildings can effectively reduce the carbon footprint in the construction sector, contributing to national-level environmental objectives. Particularly in vital tourism and economic regions such as Hainan, the promotion and application of zero-carbon architecture will become an integral part of achieving regional sustainable development, offering valuable experiences for the development of ZCB technologies in China's solar-rich areas.
