Under the background of the promotion of the new engineering construction, new opportunities and challenges appear for the heat transfer course of building environment and energy application engineering. Based on the research of the teaching status of heat transfer course in Nanjing Tech University, the teaching content, teaching method and evaluation modes are discussed. Several methods for increasing teaching efficiency are proposed while the carrier and catalyst effect of the internet under the new engineering background are confirmed. The results provide references for the teaching quality improvement of heat transfer course and the cultivation of outstanding students in building environment and energy application engineering.
