To resolve the problems of the lack of systematicness and standardization of teaching content, the great dependence on off campus practice resources, and the low learning initiative of students in the production practice of building environment and energy application engineering specialty, a project driven immersion teaching mode of production practice course is put forward. Based on the actual engineering situation as the carrier, the knowledge of construction management, intelligent operation and maintenance, etc., is systematically connected in series with all element knowledge points of the HVAC system. Students play the role of various types of work in the production process, deeply immerse in the teaching process, and become the main body of active practice and knowledge exploration. The implementation process, teaching content, process and diversified scores formation mechanism of the teaching mode can fully stimulate students’ interest in actively participating in the practice, to truly achieve the combination of theory and practice, exercise hands-on skills and strengthen theoretical knowledge, and also helps to cultivate the spirit of labor.
