Add a custom material with manually entered values when no EPD is available.
A non-verified (Custom) material is a Library entry that does not come from a published EPD. Use it when you need a material to map elements against but no EPD exists — for example, an early-phase estimate, an internal product specification, or a placeholder while you wait on a manufacturer’s documentation.Custom materials show up in the Library with the Custom type and are filterable just like any other material.
Custom materials are not third-party verified. Make sure that everyone in your organization understands that the indicator values are author-supplied estimates, not declarations.
From the Create Material page, click the Custom tab at the top.
Create Material — Custom tab, General Details, EPD Units, and EPD Sources
The Custom form is a leaner version of the Published form: there is no EPD specification, no document upload, no declaration number, and no owner/data source — because there is no underlying EPD to declare.
Enter the indicator values you want the material to contribute for each module (A1–A3, A4, A5, B1–B7, C1–C4, D).
Custom material life cycle indicators
The tables mirror the ones used for verified EPDs — environmental impacts, additional impacts, resource use, and waste output flows. Fill in whatever modules and indicators apply to your case and leave the rest as -.Most custom materials only need A1–A3 filled in. A partial row is fine; it is better to declare what you know than to invent numbers for modules you have not assessed.
Cloning an existing material (Library list → row’s ⋮ menu → Clone) is the quickest way to start a Custom material when you only need to tweak a few numbers.
Click Create Material at the bottom of the form. Your custom material appears in the Library with the Custom type tag and is available to every project in the current organization.
