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
  • Studying condensation risk and thermal bridge effect of 3D elements (e.g. brackets, fixations,...)
  • TRISCO contains revolve function allowing to easily model windows in 3D

 

BISCO Licence options

Licence options

  • BISCO is available with perpetual licences or with subscription licences.
  • Subscription licences are protected with a software licence locked to a computer (stand-alone, network or cloud-based floating). With a subscription licence you get access to the latest version of BISCO, technical support and Physibel Knowledge Base.
  • Perpetual licences are protected with a stand-alone licence locked to a hardware key. With a perpetual licence you get 1-year AMP (Annual Maintenance Plan). Renewal of AMP is not mandatory but continues your access to major version updates of BISCO, technical support and Physibel Knowledge Base.  

what's new in version 12?

  • New graphic output functions: visualisation of infra-red radiation, surface condensation and surface humidity and feature to add output labels. 
  • Integration of SCREWS according to EN ISO 12631 and LAYERS according to EN ISO 6946.
  • Improved algorithms for importing DXF files (BiscoDXF tool).
  • Software licence options (stand-alone/network floating/cloud-based floating).
