| Abstract: | In this paper the steady-state heat transfer mechanism and optical properties of frame supported glass curtain walls (FSGCW) are investigated. The differential method is applied to establish the numerical computation model of the heat transfer and optics performances of glass systems. Based on the two-dimensional steady-state heat transfer theory, the thermal performance finite element model is derived and established for frame systems in boundary conditions of convection, radiation as well as the couple of them. The FSGCW thermal performance analysis software is developed based on the secondary compiling of the AutoCAD using Visual C++ and ObjectARX. The correctness of the theory and numerical method of this paper is verified by comparing with various prevailing commercial softwares. |
