BISCO v 10 w New program performances Automatic preparation of the bitmap to minimise the user intervention for the calculation of thermal transmittance of a window frame according to EN ISO 10077. New rules for type EQUIMAT (rules CEN_DIR_I and CEN_DIR_E), TRANSMAT (rule CEN_DIR_I) and BC_FREE (rule CEN_DIR_I) to calculate thermal conductivity and convective heat transfer coefficient from the real heat flow direction. These extensions are in line with the expected revision of the standard EN ISO 10077. The RADCON module needs to be installed to use these new rules. Distances and U values can be defined in a slanted direction (using Distances window). The Derived Thermal Properties dialog box is adapted to include possible references to those (slanted) distances and U values. Updated EN ISO 10077 -2 template. Current split zone parameters can be set as default parameters (saved in the BISCO parameter file).

New cavity simulation method EN ISO 10077 -2: 2003 & 2010 use an equivalent thermal conductivity for simulating convection or conduction and radiation in air cavities. A draft EN ISO 10077 -2 standard is running for approval. It contains an improved method for cavity heat transfer. Radiation is simulated using a view factor based radiosity method. Conduction (in case of still air) is simulated using thermal conductivity of air = 0. 025 W/m. K. Convection (in case of moving air) is simulated using an increased thermal conductivity of air (Nusselt x 0. 025 W/m. K). The Nusselt number is calculated from cavity dimensions, heat transfer direction and temperature difference. It can be expected that the new method yields to results that fit better to physical reality. The new method is implemented in BISCO version 10 w with the RADCON module. Technical information on the new method is given in the document PPB_frame_cavity_heat_transfer_BISCOv 10. pdf Physibel BISCO version 10 w
