Under the background of carbon peaking and carbon neutrality, there are new missions and requirements for talent cultivation in the fields of architecture and energy, and the curriculum system provides paths and tools for achieving the goals of talent cultivation. It is an urgent task to construct an undergraduate curriculum system of three parts, six levels, spiral progression and two-way interaction based on the industry-university-research integration platform, emphasizing the feedback effect of practical teaching on curriculum knowledge. This paper explores the research directions of professional courses, forms of centralized practice and theoretical courses. Practice has proven that the teaching research and reform is 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 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 curriculum system of applied undergraduate colleges.
