How to build a construction up from sub-constructions

In LCAbyg you can build constructions out of constructions, which lets you build a multi-layer construction (e.g. an exterior wall with several layers) by combining smaller constructions.

You’re on step 2 (Structure) in the new construction wizard.

  1. Click Add building product or Add sub-construction, depending on what the layer should consist of.
  2. Choose the element from the library, or create it on the spot.
  3. Enter the quantity of the element within the overall construction.
  4. Repeat for each layer/element: a construction can contain other constructions across multiple levels.

The overall construction’s climate footprint is calculated automatically as the sum of the sub-elements, multiplied by their respective quantities.
