Once your project inventory is populated, the next step is to map each material to an EPD so RTLCA can compute GWP and other indicators. This prompt walks an AI agent through a safe, manual mapping flow — declared unit check, BR18 lifetime lookup, EPD search across Danish / Nordic / international generics, and an explicit user confirmation before any write to the project. This is the manual mapping use case — the agent always pauses for your go-ahead before calling rtlca_map_materials. For bulk auto-suggestions, run automapping separately.
Torn between two datasets for a high-impact material? Before you commit, compare the candidates and see what each one does to the project GWP.

Prerequisites

​
Run the prompt

Open a chat in your connected AI client, point the agent at the target project (by name or ID), and paste the prompt from the box below.

Map project inventory materials to EPDs (manual, user-confirmed)

Inside Real-Time LCA, you don’t need to paste this prompt. Attach the matching skill in the AI Agent instead. See Skills.

Next

For the materials that dominate the result, compare candidate EPDs to see what each dataset does to the project total before settling on one. Once your project is mapped, run a quality-assurance pass before generating reports.
