The Materials tab of the Library lists every EPD available to your organization — generic datasets, product EPDs, and anything your team has created.

The Materials library

​
Reading a row

Each row gives you the whole picture without opening anything:
  • Name, then a meta line with the EPD type (generic or product), the standard (EN 15804+A1 / +A2), the dataset, the declared unit, the declaration number, and the headline GWP.
  • A short description of what the dataset covers.
  • The material category as a coloured chip.
  • Valid to and Last modified, with an Expires soon warning when the EPD is close to its end date.
An expired EPD can no longer be used in a compliant calculation. Watch the Expires soon flag and swap the material before the date passes.

​
Narrowing the list

  • Search materials matches names as you type.
  • The flag button limits the list to EPDs allowed in your project’s country.
  • The funnel opens filters — collections, specifications, types, owners, datasources, categories, organisations, indicators, and a validity date.

​
Inspect a material

Click a row to open the material detail panel over the list.
Material detail panel with callouts for the opened row, the category chip, the dataset and standard, the declared unit and validity, the service life, and the indicator selector.Material detail panel with callouts for the opened row, the category chip, the dataset and standard, the declared unit and validity, the service life, and the indicator selector.

A material opened

The panel carries the full EPD record — owner and update date, datasource, EPD type and standard, declaration number, weight per declared unit, declared unit, issued and valid-to dates, and lifespan — plus the description and an emissions chart. Lifespan reads Not Assigned when the EPD does not state one; you will be asked for it the first time you map the material. The Indicator dropdown switches between the indicators the EPD reports — GWP, ODP, AP, POCP, ADPF, and the rest — and Emission data shows the numbers per life-cycle module instead of as a chart. Navigate EPDs steps to the next row without closing the panel.

​
Compare materials

Tick the checkbox on two or more materials. A bar appears at the bottom with what you have selected.
Two materials ticked in the library with a selection bar at the bottom showing both names, a clear action, and a Compare (2/6) button.

Selecting materials to compare

Up to six materials can be compared at once. Compare opens them side by side.
Compare view with an attribute table for two materials and a chart comparing them per declared unit.

Comparing two materials

The Overview tab lines the materials up attribute by attribute — declared unit, mass unit, suggested lifetime, datasource, owner, validity dates, material category, and EPD standard — with a chart underneath.
Lifecycle stages tab with a calculation type selector, stage chips from A1-A3 to D, a totals table, and a per-stage comparison chart.

Comparing by life-cycle stage

Lifecycle Stages compares the same materials per module. Pick a calculation type — for example Full LCA (A-D) — or switch individual stages on and off, and the totals table and chart follow. Download exports the comparison.
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.
