Open the **Constructions** tab at the top of the Library to switch the list from individual materials to multi-layer build-ups. Constructions tab showing build-ups for external walls, steel HEB columns, and wood I-joists with their standards, descriptions, and tags. ## 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 overlay for a zinc cladding build-up showing layers, weights, and a GWP chart. The panel has the same header you see on a material — **Name**, **Created by**, **Last modified**, links to **Emission data**, the category tag, and the data facts row (**Datasource**, **EPD type**, **EPD standard**, **Declaration number**, **Weight per declared unit**, **Declared unit**, **Issued**, **Valid to**, **Lifespan**). ### 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. In the example above, the build-up is 13 mm impregnated plasterboard plus an aluminium sub-structure and 0.8 mm zinc cladding — 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 The search bar and filters work the same way as on the [Materials tab](/user-guide/library/materials/browse-materials#search). They are scoped to the active tab, so a search you start on **Constructions** does not leak into **Materials** when you switch. ## 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.
