BISCO Application fields

Application fields

  • Thermal performance of windows, doors and shutters (EN ISO 10077-2)
  • Thermal performance of curtain walls (EN ISO 12631)
  • Thermal bridge analysis: heat loss calculation, surface condensation (EN ISO 10211, EN ISO 13788)
  • Thermal transmittances of building components and elements (EN ISO 6946)
  • Heat transfer via the ground (ISO 13370)
  • Heat transfer in masonry and masonry products (EN ISO 1745)

 

BISCO Input and geometric modelling

Input and geometric modelling

  • 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

 

BISCO Thermal properties and boundary conditions

Thermal properties 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

 

BISCO RADCON feature for BISCO

RADCON feature for BISCO

  • Detailed simulation of radiation based on view factors

  • Extremely fast and stable calculation of non-linear radiation problems

  • Convection based on (calculated) convective heat transfer coefficient

  • Transparent materials for small cavities: conduction + radiation

  • Validated according to EN ISO 10077-2:2017 (radiosity method)

 

BISCO Output

Output

  • Isotherms, total heat flux, heat flow lines, infra-red radiation, surface condensation and high humidity zones
  • Minimum and maximum temperature, incoming and outgoing heat flows per colour
  • Balanced air temperature for enclosed air cavities
  • Thermal transmittances and thermal bridge performances
  • Automatic report generation

 

BISCO Compatibility with other Physibel tools

Compatibility with other Physibel tools

  • 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)

 

BISCO 3D manipulation of BISCO with TRISCO

3D manipulation of BISCO with TRISCO

  • BISCO projects can be loaded in TRISCO 
  • Extrusion of profiles in 3D
