The specialized course class hours were greatly reduced in the 2019 edition talent training plan of Hefei University of Technology. Building environment and energy application engineering would be included in the pilot program of civil engineering enrollment and cultivating. Based on this background, this paper discusses the specialty construction and talent cultivation of building environment and energy application engineering in civil engineering. The specialty characteristics are analyzed in depth, and its role in civil engineering is located accurately. Green energy is identified as professional characteristic, and energy engineer is the talent training goal. Theory teaching and practice teaching should be combined closely in the teaching process, and the curriculum system design focuses on making graduates not only familiar with the organization process of the whole industrial chain of the civil engineering industry, but also proficient in professional technology and management.
