As technology continues to evolve, the construction industry is undergoing significant transformation. The widespread adoption of information-based design has made the application of artificial intelligence in architectural design an inevitable trend. This article delves into the advantages and necessity of applying generative design techniques throughout the entire process of sustainable architectural design, introducing how to apply generative design and artificial intelligence technology from the training of generative models, generation of alternative schemes, optimization of schemes, to the export of visualization in the entire process of design. The results show that by introducing generative design, not only can design efficiency be improved, but the ecological attributes of design solutions can also be significantly enhanced. The findings of this paper can provide a new perspective for sustainable development in the field of engineering construction.
