Thermal Bridge definition | TerMus BRIDGE | ACCA software

Thermal Bridge definition

With TerMus BRIDGE you can define any kind of Thermal Bridge with graphical objects that contain all the relevant data and properties necessary for numerical calculation allowing you to manually input materials and boundary characteristics.

You can import construction details in DXF/DWG CAD file format to quickly draw a thermal bridge of any shape and form. Zoom, SNAP, radial or rectangular grids give extra drawing guidance.

If your Thermal Bridge is among the standard configuration models, you can easily select it from the archive (EN ISO 14863), and customize its thermal and geometric data to quickly generate the calculation model.

TerMus BRIDGE is integrated with TerMus PLUS, the ACCA dynamic energy analysis and simulation software.

Thanks to the live connection between the two solutions you can acquire the materials data inserted TerMus PLUS in TerMus BRIDGE.

Numerical calculations with TheBriNA integrated solver | TerMus BRIDGE | ACCA software

Numerical calculations with TheBriNA integrated solver

With TerMus BRIDGE you’ll be able to quickly get the thermal bridge calculation from a simple drawing thanks to TheBriNA calculation solver (Thermal Bridges Numerical Analysis) included in the software.

TerMus BRIDGE allows you to:

  • calculate the (Ψ Psi-value) linear thermal transmittance of thermal bridges
  • evaluate heat flows, thermal coupling coefficients and thermal bridges towards soils or any other temperature zones and verify the correct configuration of the thermal bridges in a given structure.
  • generate a chromatic contour line representation for further detailing including the critical isotherm curves
  • evaluate the risk of mould formation according to the EN ISO 13788 technical standard
  • evaluate the fRsi temperature factor
  • the minimum temperature risk for mould growth

TerMus BRIDGE analyses thermal bridges determining the linear thermal transmittance and heat flows using a finite element analysis model compliant with EN ISO 10211.

Mould growth risk assessment | TerMus BRIDGE | ACCA software

Mould growth risk assessment

TerMus BRIDGE, in accordance with EN ISO 13788, allows you to determine the minimum surface temperature to assess the risk of mould formation taking into account the effects of air humidity.

Assess the risk of mould growth on building surfaces in advance and avoid critical dimensional errors already in the design.
