Add and manage embodied carbon factors

To enable embodied carbon to be calculated in Tekla Structural Designer default embodied carbon factor (ECF) values have to be set up and saved. You can set up a local set of factors which apply to the current model only and a global set of factors which serve as the defaults for new models.

Set up a global set of factors

When setting up standard embodied carbon factors you should add them directly to a global settings set so that they are available for all new models.

This can be done as follows:

  1. On the Home tab, click Settings
  2. On the Embodied Carbon page of the dialog, click Edit...

The Embodied Carbon Factors dialog box is displayed from where you can manage the global set of factors for the active setting set.

When you have finished, click OK to close the dialog and OK to close Settings

Set up and edit the local set of factors

The local set of factors are initially inherited from the global set. Often you might want to customize these by making specific factors inactive. You might also want to add project specific factors, for example cladding for walls and roofs.

These operations should be performed using the Embodied Carbon Factors dialog box, which is accessed as follows:

On the Home tab, click Embodied Carbon Factors

The Embodied Carbon Factors dialog box is displayed from where you can manage the local set of factors.

Note: Changes to the local set do not get applied to new models unless they are saved to a global settings set.
When you have finished, click OK to close the dialog.
