Green building design has also sparked a trend in the construction industry and is being widely applied. Therefore, when enterprises engage in architectural design, they should actively respond to national environmental protection policies, change traditional design methods, and adopt new energy-saving and environmentally friendly green building concepts. This paper uses data mining and BIM (Building Information Modeling) technology to analyse the green building design concept and verifies its application in architectural design through practical examples. Data mining technology analyses the key factors influencing green building design and establishes relevant correlations. The application of BIM systematic management technology to green building design is studied. The results indicate that the data mining-based graphical green building design better meets the requirements of modern architecture.
