Each row in the Materials list represents one material. The card shows the **name**, **EPD type**, **EPD standard**, **datasource** (for example, *Real-Time LCA*), a short description, the last modified date, and tags such as the material category or attributes like *hardwood*. Materials list with row-level Compare, PDF, favorite, and overflow actions. The row-level actions on the right of each material give you everything you need without opening it: | Action | What it does | | ---------------- | ------------------------------------------------------------------------------- | | **PDF** | Open the EPD document (when one is attached). | | **Compare** | Add the material to the comparison set. | | **Bookmark** | Save the material to a [collection](/user-guide/library/materials/collections). | | **Open in tab** | Open the material in its own browser tab. | | **Star** | Mark the material as a favorite. | | **⋮ (overflow)** | Additional actions — for example, **Clone**. | ## Inspect a material Click anywhere on a row to open the **material detail panel** as an overlay on the list. Material detail overlay showing owner, name, datasources, EPD type, declaration number, declared unit, lifespan, description, and a stage chart. The header summarises everything required to assess the material: * **Owner**, **Name**, **Created by**, and **Last modified**. * Quick links to **Documentation** (the EPD PDF) and **Emission data**, plus tags such as *hardwood*. * A row of facts: **Datasources**, **EPD type**, **EPD standard**, **Declaration number**, **Weight per declared unit**, **Declared unit**, **Issued**, **Valid to**, and **Lifespan**. * A short description on the left and an emissions chart on the right. ### Switch the displayed indicator Use the **Indicator** dropdown above the chart to view any of the environmental indicators reported on the EPD — for example, **GWP**, **ODP**, **AP**, **POCP**, or **ADPF**. Indicator dropdown listing GWP, ODP, AP, POCP, and ADPF among others. ### See all lifecycle stages The Overview chart highlights the modules with values for the selected indicator (A1–A3, A4, A5, B1–B7, C1–C4, and D). For the full numeric breakdown, switch to the **Lifecycle Stages** view. Lifecycle stages table showing every indicator value per module. Every indicator is listed with its unit and the value for each module — useful when you need exact numbers for reporting. ### Expand to a full page The icon in the top right of the panel opens the material on its own page. Tooltip on the expand button in the material detail header. The full-page view shows the same data with more room — handy when sharing a direct link with a teammate. Material Detail page rendered standalone instead of as an overlay. ### Open the EPD document When a row shows a **PDF** badge, click it to open the EPD document directly in the browser. In-app PDF viewer showing an Environmental Product Declaration for Wood flooring – TARKETT. ## Search The search bar across the top of the Library searches by **material name** (and synonyms). Results update as you type. Materials list filtered by the search term Galvanized steel profile. Search works alongside the filters and the **Materials/Constructions** tab — narrowing one does not reset the others. ## Filter Click the funnel icon next to the search bar to open the **Filters** panel. Filters panel with Favorites, At least valid to, Collections, Specifications, Types, Owners, Datasources, Categories, Organisations, and Indicators. From top to bottom: * **Favorites** — only the materials you have starred. * **At least valid to** — show only EPDs that remain valid on or after the date you pick. * **Collections** — narrow to materials saved to a specific collection. * **Specifications** — filter by the EPD specification standard (for example, *EN15804+A2*). * **Types** — *Custom*, *Generic*, *Industry*, or *Product*. * **Owners** — the manufacturer or organization that issued the EPD. * **Datasources** — the upstream database (for example, *Ökobaudat 2023-I*, *EPD Danmark*). * **Categories** — material category (*Aluminium*, *Brick*, *Steel*…). * **Organisations** — which workspace owns the material. * **Indicators** — show only materials that report the selected indicator (for example, *GWP*). You can combine filters freely; click **Clear** at the top of the panel to reset all of them. Collections filter expanded showing Low Carbon Collection. Specification filter listing EN15804A1 and EN15804A2. Type filter with Custom, Generic, Industry, and Product. Owner filter listing ASSA ABLOY, Associated Weavers, Astron, Aulis Lundell, Aura Light, Auraland Energibygg. Datasource filter listing B-EPD, Bovateket, Building Research Institute, CERTBUD, Ecovave. Category filter listing Aerated concrete, Aluminium, Asphalt, Brick, Concrete and cement mortar, Construction wood, Copper, Fibers and felt. Organisations filter listing Acme Corp, Other, and Real-Time LCA. Indicators filter listing GWP and GWP-IOBC. ## Favorite a material Click the **star** on a row to mark a material as a favorite. Favorited rows are highlighted, and you can find them quickly with the **Favorites** filter at the top of the filters panel. Galvanized steel profile row highlighted with a filled yellow star. ## Compare materials Use **Compare** on each row to add a material to the comparison set. The funnel icon shows a counter with the number of materials currently selected. Top of the Library showing a 2 next to the compare icon after adding two materials. Click the compare icon in the toolbar to open the **Compare** view. Compare modal listing Declared unit, Mass unit, Suggested lifetime, Datasource, Owner, Valid from, Valid to, Material category, and EPD standard for two materials. The Compare modal lets you: * Switch the **Indicator** at the top to recalculate the chart for a different impact category. * Click **Download comparison** to export the data. * Toggle between **Overview** (side-by-side attributes) and **Lifecycle Stages** (per-module values). * Read the underlying numbers in a unified table. Scroll down to the **Comparing materials** chart for a per-module visual comparison. Bar chart comparing Galvanized steel profile and Large gauge steel profiles Steel 4e across A1-A3, A4, A5, B-modules, C-modules, and D. Per EN 15804+A2, EPD data is only directly comparable when the building context and the product's specific performance characteristics are taken into account. The disclaimer at the bottom of the Compare view repeats this. ## Clone a material To start a new material from an existing one — for example, to author a variant — open the row's **⋮ overflow menu** and choose **Clone**. Overflow menu next to a material with a Clone action. Cloning copies the material's metadata and indicator values into the [Create Material](/user-guide/library/materials/create-materials) form so you can tweak whatever you need before saving.
