ZUB Argos

• New: Import/export interface between ZUB Argos and ZUB E-CAD 
  ZUB E-CAD makes it easy to determine the lengths of thermal bridges. Thermal bridge lengths can be imported from ZUB E-CAD into ZUB Argos. Thermal bridges can also be imported from ZUB Argos into ZUB E-CAD.
  A detailed description of the new function is available via this link.

Information on entering custom window profiles

Custom window profiles can be entered in ZUB Argos Pro. However, creating these window profiles remains a highly complex and time-consuming process. This includes, for example, interpreting CAD templates and correctly assigning their elements, positioning components with millimetre or sub-millimetre accuracy, and individually assessing the thermal conductivity of air-filled cavities. We therefore recommend using the reference components provided.

The support service expressly does not include assistance with the creation of custom window profiles or similar components.

To help you get started with the software, please watch our video tutorials. Additional tutorials are available under Support / Tutorials.

Further tutorials can be found in the support section.

Modelling is a central element of thermal bridge calculation.

In ZUB Argos, real connection details are represented geometrically, including:

• Walls

• Floors and ceilings

• Window and French-door connections

• Floor slabs

• Façade connections

• Roof connections

The modelling is based on:

• Polygons and rectangles

• Real building component assemblies

Relevant standard requirements for section planes must be observed, for example:

• Minimum distances of ≥ 1 m or three times the component thickness

• Use of symmetry planes

• Consideration of the ground in foundation details

This ensures that the calculation is carried out in a physically accurate and standards-compliant manner.

The key strength of ZUB Argos lies in its calculation capabilities.

The software:

• Calculates heat flows

• Visualizes temperature distributions

• Determines ψ-values

The ψ-value represents the additional heat loss caused by a thermal bridge and is determined using:

• Thermal coupling coefficient (L2D)

• U-values

• Temperature differences

This calculation is essential for:

• GEG and GModG verification

• Energy performance assessment

• Optimization of building constructions

The results are presented not only numerically, but also visually.

ZUB Argos provides:

• Temperature fields

• Isotherms (lines of equal temperature)

• Heat flow visualizations

• FEM mesh visualization

• Comprehensive reporting functions, including KfW forms and computational proof of equivalence

• ψ-value correction factors for replacement systems in accordance with DIN 4108 Supplement 2

• Temperature correction in accordance with DIN 4108 Supplement 2 for the fRsi calculation of window and French-door connections

This makes it possible to:

• Identify critical areas immediately

• Understand heat losses

• Optimize problem areas in a targeted manner

This visualization is a decisive advantage, particularly for complex construction details.

ZUB Argos includes comprehensive integrated databases:

Building materials database
Materials with relevant building physics properties.

Construction database
Reusable building component assemblies.

Thermal bridge catalogue in accordance with DIN 4108 Supplement 2 (PRO)

• Details from the 2006 and 2019 editions

• Approximately 400 reference details, including ψ-reference values

In many cases, this eliminates the need to recreate details from scratch.

A particular advantage is the ability to compare custom details with reference details.

ZUB Argos enables:

• Linking custom constructions with details from DIN 4108 Supplement 2

• Automatic assignment of reference values

• Use for GEG and KfW verification

This significantly simplifies the proof of equivalence.

Thermal bridges can lead to:

• Increased energy consumption

• Lower surface temperatures

• Risk of mould growth

• Reduced thermal comfort

By definition, thermal bridges occur in areas where heat flow is locally increased, for example due to:

• Changes in materials

• Geometric changes

• Construction details

The physical complexity of thermal bridges makes manual calculation virtually impossible.

ZUB Argos makes it possible to:

• Perform standards-compliant calculations

• Model complex construction details

• Present results in a clear and comprehensible manner
