With the concern on the quality of the building environment, the course teaching of architectural physics has been paid more and more attention by universities and colleges. We analyzed shortcomings of the traditional course teaching of architectural physics and the application of digital technology in architectural design and presented the great potential digital technology application in course teaching of architectural physics. Combined with the course teaching reform of architectural physics in Chongqing University, we provided a new idea and direction for enhancing the students’ analysis ability on the physical environment and improving the course teaching effect of architectural physics.
