Compare EPDs
Compare environmental declarations on a supported common basis.
What it does
Give Norma the declarations and the comparison question. Norma checks whether units, product scope and life-cycle boundaries align before comparing impacts. Incompatible evidence stays visibly unresolved.
Install
Connect Arch Studio in Claude or ChatGPT, then return to your conversation and ask Norma for the task. Your assistant uses its available file access and tools to carry out the skill.
Add to Claude

Usage
Ask Norma in plain language. With Arch Studio connected through MCP, no $ or / command is required. Norma is your assistant working with Arch Studio.
Use Arch Studio to compare these two flooring EPDs. First check declared units, product variants, impact indicators and life-cycle stages. If the inputs are incompatible, explain the gap instead of ranking the products.The full catalog lives in your assistant once Arch Studio is connected. Ask: Norma, what can you do?

What it checks
Product and unit
Norma verifies the product variant and declared or functional unit for each declaration.
Stages and indicators
Norma checks that the reported life-cycle stages and impact indicators support the intended comparison.
Conversions and ranking
Norma converts only from supported inputs and explains any excluded data. Norma does not rank products on incompatible evidence.
Workflow
- Identify — Norma reads the declarations and comparison criteria.
- Align — Norma checks units, scope and boundaries and identifies missing conversion evidence.
- Compare — Norma presents the supported comparisons and unresolved differences.
Pairs with
EPD specification clauses. Norma can use reviewed comparison evidence when drafting environmental specification requirements.
