Title: What


1
Whats new in TRISCOversion
2
New performances summary
- TriscoDxf tool for fast input of 2D CAD
drawings (DXF files).- New template data file
initialising material properties and boundary
conditions.- Import bitmap based on either
superposition (i.e. with possible overlaps) or
juxtaposition (i.e. without any overlap) of
blocks.- Automatic grid subdivision function.-
Automatic initialisation of areas and U values of
flanking elements of a thermal bridge. The
areas are based on either exterior or interior
dimensions.- The U value of any flanking element
can be overwritten by an enforced U value.- Show
areas and U values in graphic output.- Revolve a
2D geometry containing a cross section (e.g. of a
window frame) over an angle of 90 to form a 3D
corner joint.- Split zones function.-
Equivalent thermal conductivities based on
editable surface emissivities across cavities.-
Critical relative humidity for surface
condensation.- Batch calculation write
calculation results (as in text output window)
into text file.- Automatic report generator.

Conversion of DXF drawings to BMP bitmapsfor
importing in TRISCO
TRISCO-DXF features- Input DXF file, typically
containing one or multiple construction detail
sections- Output BMP file, each colour
representing a material, a cavity or a boundary
condition- User defined pixel size- Multiple
Fill Mode options - Using template colours
material properties and boundary conditions are
automated in TRISCO

New colour template- material thermal
conductivity lt EN ISO 10456- surface heat
transfer coefficients lt EN ISO 6946- cavity
equivalent thermal conductivity lt EN ISO 6946-
A template can be loaded in background when
opening TRISCO.- Templates can be easily
modified.- EN ISO 10077-2 (window frames)
template available.

New colour templateEN ISO 10456 EN ISO 6946
Importing the bitmap in TRISCO, the pixel
resolution as specified in the DXFgtBMP
conversion is respected.
Importing the bitmap in TRISCO, the material
properties and boundary conditions are
automatically initialised.
7
Importing bitmap superposition or juxtaposition
Importing a bitmap in TRISCO, blocks are
generated either using superposition (with
possible overlaps) or juxtaposition (without any
overlaps).Superposition minimises the number of
blocks. Juxtaposition can be interesting for 3D
editing.
8
Automatic grid subdivision function
Applying Auto Split

(example values)- Meshes smaller than 200 mm are
split in parts of maximum 10 mm wide.- Larger
meshes are first split in 2 if they arent at
border positions,- and then split using a split
ratio either of 1.25 (rightwards or
downwards) or of 1/1.25 (leftwards or
upwards).

Automatic initialisation of areas and U values
of thermal bridge flanking elements
To derive the linear thermal transmittance ? of a
2D thermal bridge- the dimensions of the
flanking elements are initialised automatically,
either using external or internal dimensions.-
the U-values of the flanking elements are
initialised automatically.

Automatic initialisation of areas and U values
of thermal bridge flanking elements
To derive the linear thermal transmittance ? of a
2D thermal bridge- the dimensions of the
flanking elements are initialised automatically,
either using external or internal dimensions.-
the U-values of the flanking elements are
initialised automatically.
14
Using an enforced U value of a flanking element
The linear thermal transmittance ? is a
characteristic of a 2D thermal bridge. However,
in some cases the ?-value can be derived for
construction details in which the heat transfer
is 3D.In the example floor-wall junction above,
the floor U-value is derived first using a 2D
simulation.
15
Using an enforced U value of a flanking element
The derived floor U-value can be entered as an
enforced U-value.In that way the linear thermal
transmittance ? of the floor-wall junction can be
derived.
16
Improved graphic output
The graphic output is improved graphics showing
areas and U values can be created.

The powerful revolve function allows to create
automatically a 3D detail from a 2D cross
section.This allows for example a fast 3D
surface condensation risk analysis.

21
Split Zone function
For each air cavity an equivalent thermal
conductivity needs to be calculated and therefore
each air cavity needs its own colour. The Split
Zone function allows to assign different colours
to blocks that have initially the same colour.
In the example the white colour (index 1) is
split into grey colours (starting at index 192).

23
Equivalent thermal conductivitiesbased on
editable surface emissivities across cavities
The equivalent thermal conductivity of an air
cavity as specified in the standards EN ISO 6946
and EN ISO 10077-2 depends on the infrared
emissivity of the surfaces that are parallel to
the environments. A default emissivity of 0.9 is
assumed when calculating the equivalent thermal
conductivity (TRISCO EQUIMAT type).In TRISCO
version 12w the emissivity of these surfaces can
be edited.The example shown concerns a thin
insulation layer with low emissivity surfaces
applied in a roof.Alternatively using the
RADCON module allows a physical radiation
simulation.

Equivalent thermal conductivitiesbased on
editable surface emissivities across cavities
Example with thin insulation layer with surface
emissivity 0.9 (paper foil at both sides).

editable surface emissivities across cavities
Example with thin insulation layer with surface
emissivity 0.1 (aluminium foil at both sides).
26
Critical relative humidity for surface
condensation
The critical relative humidity at which surface
condensation occurs is reported.
27
Result text file created from batch calculation
Result text files are automatically created when
calculating in batch mode.
28
Automatic report generator
The automatic report generator creates multiple
text and graphical data and result files.
29
Automatic report generator
Using the macro TRISCO_Load these data and
results files can be imported automatically into
the MS-Word document TriscoReportTemplate.doc.

TriscoReportTemplate.doc can easily be prepared.
