Managing linear thermal bridge libraries
Defining linear thermal bridges in the thermal model libraries allows users to detail their data, such as linear thermal transmittance. This data can be entered manually, imported from reference standard catalogues, or calculated using a linear finite element calculation model and will affect the thermal load analysis performed by the program.
The tools for managing the linear thermal bridge libraries in the thermal model of the building are located in the lower tab "Thermal loads", in the upper tab "Thermal model" and, in the "Project" definition area, in the "Libraries" tree located by default on the left-hand side.
The "Edge processing" option in the top toolbar is then used to edit and adjust the thermal bridges of the model as a whole. This way, the program automatically modifies the data of the thermal bridge types according to the configuration parameters of the edge processing.
However, a particular type of bridge can be edited or modified on an ad hoc basis using the options discussed in this section.
Linear thermal bridge library
When creating or editing a thermal bridge type, the program offers the possibility to configure the following parameters:
- Reference
- Type
The following types are available:- Slab-on-ground floor
- Front of the slab
- Outgoing corner
- Incoming corner
- Windowsill
- Lintel
- Jambs
- Description
- Psi (W/(m·K))
Linear thermal transmittance. - Value (Not defined / Entered / ISO 14683 / ISO 10211)
Origin of the value.
Automated data import
Thermal bridging data can be imported automatically using the following standards and methods:
- ISO 14683
Imports the thermal bridging data collected in different types of the ISO 14683 standard.
- ISO 10211
The thermal transmittance of linear thermal bridges can be determined using a finite element analysis based on EN ISO 10211. This method is equivalent to that used by independent programs such as CYPETHERM BRIDGES. The program displays a wizard with the following tabs, which show the following:- About…
Information text on the analysis method used and its implementation in the program. - Types
Selects the type of thermal bridge. - Model
Details the thermal bridge model by defining the layers of material located in each of the positions indicated in the graph. - Report
Report on the analysis of the linear thermal transmittance of the thermal bridge using the finite element analysis proposed in the indicated code.
