Open the Constructions tab at the top of the Library to switch the list from individual materials to multi-layer build-ups.
Constructions tab listing build-ups with their declared unit, layer description, category tag, and last modified date.

Constructions tab in the Library

Reading a construction row

Each row gives you everything needed to decide whether the construction is the right fit:
  • Name — the build-up’s name (for example, Yderside, zinkplader, underkonstruktion i aluminium).
  • Standard tag — Construction, plus the calculation framework it follows (for example, LCAbyg (2023)).
  • Short description — typical materials and thicknesses.
  • Tags — the dominant material category, such as Gips, Stål, or Konstruktionstræ.
  • Last modified date.
  • Compare, open in tab, favorite, and the ⋮ overflow menu — the same row-level actions you have on materials.
The toolbar above the list — search, filter, and + Construction — also mirrors the Materials tab. Search and filters apply to the active tab only.

Inspect a construction

Click a row to open the construction detail panel as an overlay on the list.
Construction detail panel with callouts for the opened construction, the declared unit, the layer rows, and the amount and share per unit.Construction detail panel with callouts for the opened construction, the declared unit, the layer rows, and the amount and share per unit.

A construction opened

The header carries the construction’s name, its owner, and when it was last updated, plus Emission data and the category tag. Below it, Declared unit is the amount the whole build-up is declared per — usually 1 m². Then comes the layer list: one row per material in the build-up, each with the material it maps to, its lifetime, its category, and how much of it goes into one declared unit — 1 m² pr. 1 m², 1.24 kg pr. 1 m² — followed by the share it represents.

Layers

The middle section lists the layers that make up the construction. Each layer shows:
  • The material name and its lifetime in years.
  • A category tag (for example, Gips, Aluminium, Zink).
  • The mass per declared unit (m²) for that layer and its share of the total weight.
At the bottom of the panel is the same plain-language description shown on the row.

Indicator chart

On the right, the Indicator dropdown lets you switch between environmental indicators (GWP, ODP, AP, POCP, ADPF, …) just like on a material. The chart shows the construction’s combined values across the EN 15804 modules (A1–A3, A4, A5, B1–B7, C1–C4, D).

Open in a tab or expand

The icon in the top-right of the panel opens the construction as a full standalone page — useful for sharing a direct link with a teammate or printing.

Search and filter

Constructions tab with the filters panel open showing favorites, collections, units, owners, and organisations.

Filtering constructions

The search bar and filters work the same way as on the Materials tab. They are scoped to the active tab, so a search you start on Constructions does not leak into Materials when you switch. Constructions filter by Units, Owners, and Organisations rather than by EPD specifics — Organisations is the one to reach for when you want only the build-ups your own team authored.

Edit, clone, or delete

Construction row with its overflow menu open, offering Edit, Clone, and Delete.

The row menu

The ⋮ menu on a construction you own offers Edit, Clone, and Delete. Cloning opens the create form prefilled with the layers and dimensions, which is the quickest way to make a 400 mm variant of a 300 mm wall.
Editing a construction changes it everywhere it is already mapped, and the affected projects recalculate. Clone it instead when you want a variant and need the original left alone.

Favorite and compare

The star and Compare actions on each row behave exactly like they do for materials — favorites are recalled via the Favorites filter, and Compare opens the side-by-side view for the constructions you have selected.
