Under the background of " carbon peak, carbon neutralization, " there are new missions and requirements for the cultivation of talents in the field of architecture and energy. The construction of curriculum system is based on the platform of integration of production, teaching and research, emphasizing the feedback effect of practical teaching on curriculum knowledge. On this basis, a spiral progressive curriculum system is formed in the whole process of undergraduate semester, forming three six-level and two-way interaction of theory and practice. According to the main research direction, the professional courses are subdivided into three parts : indoor and outdoor environment control, cold and heat sources and equipment, energy transmission and distribution system. The centralized practice has formed two levels of basic practice and professional practice ; theoretical courses are divided into mathematics and natural science foundation, professional foundation, professional characteristics, professional core and so on. Through the practical test of four graduates, it is proved that the construction mode of the curriculum system is feasible. In the teaching practice, the teaching research and reform are constantly promoted, and the construction path of the curriculum system to actively adapt to the development of the industry and the deep integration of schools and enterprises to meet the local needs is effective. Considering the three indicators of systematicness, hierarchy and innovation, the design and optimization method of the curriculum teaching system structure meets the design requirements of the curriculum system of applied undergraduate schools.
