What BISCO users already knew
BISCO is a thermal analysis program for
two-dimensional steady state heat transfer.
BISCO is very useful for the thermal analysis of
windows and doors (EN ISO 10077-2), thermal
bridges (EN ISO 10211), building components and
elements (EN ISO 6946), hollow brick masonry and
ground heat losses (ISO 13370). BISCO was first
developed by Physibel in 1995 and due to its
popularity several new versions with an improved
user friendliness and with increasing simulation
power were developed since that time. It became
a reference program in consultancy, industry and
research in the thermal simulation world.Today
we are proud to present you BISCO version 9w.
Related Physibel programs.The program module
RADCON allows a more detailed conduction -
radiation - convection analysis.The program
BISTRA allows a transient 2D thermal analysis
(fire analysis, analysis of problems related to
solar radiation).The programs TRISCO and VOLTRA
allow three-dimensional steady state and
transient thermal simulations.

Whats new in BISCO version 9w ? Summary of new
performances
- Improved input of DXF files.- Read/write
compressed BMP files.- New bitmap editing
functions (e.g. import bitmap).- Faster response
times when using drawing tools.- Optimise air
cavities by detecting grooves and small
interconnections.- Equivalent thermal
conductivities based on editable surface
emissivities around cavities.- Equivalent
thermal conductivities based on calculated heat
flow direction in cavities.- Second insulation
panel possible for window frame calculation.-
Automatic initialisation of distances for window
frame calculation.- Detect zones of reduced heat
transfer.- View and adjust U values at bitmap
borders.- Relative humidity for surface
condensation.- Automatic report generator.

New BISCO-DXF module to convertDXF drawings into
coloured BMP bitmaps
New BISCO-DXF features.- Draw bitmap outline
inside window with DXF drawing.- Change bitmap
size and pixel size through dialog box.- Load
layer definitions from file.- Load colour
palette from bitmap template file.- Calculate
bitmap without automatic save.- Save
(compressed) bitmap and layer definitions into
files with user defined file names.

The bitmap conversion is limited to the zoomed
area (blue rectangle).The pixel size is editable.

13
Symmetry option for bitmap border cavities
Up to BISCO version 8w bitmap borders were always
considered as symmetry axes.The new option
allows considering cavities as closed by the
border, which causes slightly lower equivalent
thermal conductivities.

Automatic detection of heat flow direction in
cavities
15
Compared to previous BISCO versions, version 9w
can result in slightly lower frame U-values
according to the EN ISO 10077-2 standard, because
of the last 3 new performances - Optimised
subdivision of cavities in case of
interconnections lt 2 mm - Symmetry option for
bitmap border cavities- Automatic detection of
heat flow direction in cavities
16
Editable cavity surface emissivities
This feature allows calculating the cavity
equivalent thermal conductivity according to the
formula in EN ISO 10077-2.The RADCON module
allows a physically much more correct approach.
Using the colour type TRANSMAT, the conduction
through the air or gas at rest and the radiation
between the surface elements bordering the cavity
are simulated correctly.Using the colour type
BC-FREE, the convection between the air and the
surface elements and the radiation between them
are considered.

Use of a hard material when deleting (small)
zones
Up to version BISCO version 8w the pixels to be
deleted were replaced by the surrounding pixels
BISCO version 9w allows to define hard materials
that are not used when replacing pixels to be
deleted

Automatic distance initialisation for frame and
insulation panel

Automatic use of distances in Uframe definition

New distance definition features
extent MIN (line through clicked point up to
colour border) MAX (based on
dimension of bounding box of colour in bitmap)
FREE (coordinates of end points X1, Y1, X2, Y2
are freely modified)

Use of an alternative EN ISO 10077-2 template
with more soft colours for colouring cavities
BISCO version 9w allows a conversion between the
different templates
29
Generation of graphic and text files for reporting
Up to 8 bitmaps can be defined with parameters to
show or hide object lines, triangulation mesh,
isothermal lines, heat flow lines, distances,
legend and fill option (bitmap, materials,
temperatures, heat fluxes, heat flows, or no
fill).Data and result text files are created
automatically key values (pixel size, global
triangulation size, number of nodes, temperature
factor, linear thermal transmittance, equivalent
thermal transmittance, thermal transmittances of
flanking elements, frame, insulation panels) and
report text files (data, results, material
properties, boundary conditions, equivalent
thermal conductivities of cavities, temperature
factor table, linear thermal transmittance table,
frame thermal transmittance table).
