The implementation of the "new engineering" strategy is an important measure for China to cope with the global competition and promote the creation of a higher education power. For positive response to the national major development strategy, following the industry development trend, Tianjin university is seizing the opportunity to offer the intelligent building major on its advantage in disciplines of building environment and energy application engineering, electrical automation, etc. By building a teaching mode of mutual penetration and cross integration among disciplines, the aim is to cultivate talents that meet the needs of national development strategy. Since the intelligent building major of Tianjin University is still in its infancy and has not been widely recognized by students of other majors, it is of great significance to open a public elective course that can provide course selection for students of multiple colleges. In intelligent building course construction, the modular curriculum system is taken to design the focus of different teaching stage and intensive content. Combined with innovative teaching materials, theory teaching of technology application prospect and regression technical principle of practice teaching, supplemented with joint teaching by teachers with different research direction and professional background, the multidisciplinary integration curriculum features is interpreted, and the industry development and practical key points are paid attention to in the process of teaching. Through the analysis of curriculum organization mode, teaching arrangement and curriculum evaluation, the hybrid teaching mode for the intelligent building innovative course is put forward, the modular multi-dimensional cross course system and multi-disciplinary integration education platform are constructed, and the innovative talent training mode of mixed teaching is established.
