Download PowerPoint Show on U-value calculation of window frame (1.3 Mb)

• Conversion of DXF file to 256 colours BMP file, via input of colour for each DXF layer and input of bitmap resolution
• 256 colours BMP file contains geometric description required by BISCO
• Colours in BMP file are indices to materials and boundary conditions

• Linked to bitmap via colours
• Materials: thermal conductivity, surface emissivity.
  Automatic calculation of equivalent thermal conductivity for air cavities.
• Optimisation of air cavities by detecting grooves and interconnections
• Surface boundary conditions: ambient temperature, heat transfer coefficient, heat flux.
  Improved simulation of radiation and convection by use of RADCON module.
• Detection of surfaces with increased surface resistance (in edges or junctions between two surfaces)
• Line boundary conditions (fixed temperature or flux) in borderlines between two colours

• Colours with predefined thermal properties when starting from template file
• Load thermal properties from material database
• Triangular mesh generation based on mesh size per colour
• Calculation of linear thermal transmittance, and thermal transmittance of a window frame

• Isotherms, heat flux magnitudes, heat flow lines
• Minimum and maximum temperature, incoming and leaving heat flows per colour
• Balanced air temperature for enclosed air cavities
• Thermal transmittances and thermal bridge performances
• Automatic report generation

• Thermal bridge analysis: heat loss calculation, surface condensation (EN ISO 10211, ISO 13788)
• Thermal transmittances of building components and elements (EN ISO 6946)
• Thermal performance of windows, doors and shutters (EN ISO 10077-2)
• Heat transfer via the ground (ISO 13370)

• Dynamic version: BISTRA
• TRISCO can read BISCO data (creates extruded profile, based on bitmap)
• SOLIDO can read BISCO data (creates STL files per colour for extruded profile, based on triangulation mesh)
