BISCO
Efficient method to calculate 2D thermal transmittances via .dxf input according to EN 10077-2:2017
Features
- Steady-state thermal simulation of all shapes in 2D
- Automated input from DXF files via bitmaps
- Powerful finite element solver allows complex geometries with minimal simulation time
- Optimised for automated use according to EN ISO 10077-2:2017 (including radiosity method for cavities)
- Automatic reporting
- Software operational in English, French, German and Dutch
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)
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
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
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)
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
