Research on calculation methods for thermla performance of thermal bridge in building envelope

摘要

In accordance to comprehensive analysis of current situation of theoretical study on calculation methods for heat transfer of thermal bridge in building envelope, this paper has introduced the calculation method for heat transfer of thermal bridge in building envelope by using the PTemp, the 2-D software which is developed by the second author. Comparison with experimental results and numerical solutions show good agreement with the proposed 2-D software. This simulation tool provides foundation for revising the China building energy efficiency code.
