Against the backdrop of global climate change and resource constraints, green buildings have become the core direction for the transformation and upgrading of the construction industry. As the source of project cost control, the design phase exerts a decisive impact on the economic efficiency and environmental performance of buildings throughout their life cycle. Based on the whole-life-cycle cost theory, this paper systematically analyzes the value, existing problems, and optimization paths of cost management in the design phase of green buildings, combined with practical tools such as BIM technology and standardized design. The research shows that by strengthening multi-dimensional collaboration, dynamic cost control, and the application of technological innovation in the design phase, the coordinated optimization of economic and environmental benefits can be achieved, providing theoretical support and practical guidance for the sustainable development of the industry.
