Under the dual-carbon background, green building is a revolution in the development process of the construction industry, which has a far-reaching impact on the transformation of people’s concept of life and employment. This paper is oriented to the characteristics of the traditional construction industry and constructs the training mode for innovative green building professionals based on professional setting and practical ability. To verify its effectiveness, the fuzzy comprehensive evaluation method is utilized to determine the affiliation function and construct the evaluation system for talent cultivation mode. The evaluation index weights are determined using the improved entropy weight method at the same time. In the job demand analysis, the demand for sustainability design positions has grown the most, rising from 1,003 in 2005 to 5,172 in 2020, which is 5.16 times the original number. It shows that the number of positions related to low-carbon energy in the construction industry is increasing. In addition, from the perspective of talent cultivation mode, the average difference between the two different construction talent cultivation modes in the talent cultivation concept is the largest, .911. The average difference between the two modes in terms of students’ sense of identity is 1.345, and the significance of the difference is 0.000<0.005. Therefore, the green construction talent cultivation mode constructed in this paper can effectively strengthen the students’ practical ability of green construction and adapt to the current status quo of construction industry positions. Adjust to the current status of construction industry positions.
