The purpose of the experimental teaching reform of architectural physics course, which is set up for students majored in architecture, is to ensure students having theoretical and sensible understanding of building physical indexes, having thorough understanding of the causality between thermal environmental parameters and the results of building thermal environment, and being able to use them on building environment control practice. We introduced thoughts and practice about the exploratory experimental teaching reform named as "building thermal environmental parameters measuring and analysis of thermal comfort". We introduced the change from single parameter measuring to comprehensive thermal environmental parameters measuring and analysis and from experimental data analysis to the analysis and reconstruction of building thermal environment, and how the students design experiment scheme by themselves. Then we presented the procedure and results of the experimental teaching, as well as the further thoughts about it.
