How to compare scenarios

Use EPD scenarios to compare Document Baseline results with product-specific options, and mark one scenario as the project Reference Case.

Steps

8 steps

1
Open scenario analysis
Go to the Scenario Analysis tab in your project.
2
Create a scenario
Click 'Create Scenario' and give it a clear name.
3
Choose a material
Select the material category you want to swap.
4
Search for an EPD
Find a product-specific EPD that matches your material.
5
Review EPD details
Confirm the functional unit, scope and validity period.
6
Apply to matching items
Map the EPD to the relevant line items in the project.
7
Review the reduction
Compare the scenario total with the Document Baseline result.
8
Set a reference case
Optionally mark Document Baseline or a scenario as the project Reference Case for comparisons.

Notes & tips

Quick check

Only select EPDs that match the actual product, material type and functional unit.

Reference Case vs Document Baseline

Document Baseline is the document calculation baseline used for reductions. The Reference Case is the optional project-wide scenario you choose as the comparison base.

Good scenario names

Low-carbon concrete option · Supplier EPD scenario · Tender proposed scenario · Combined EPD scenario.

Common issue: The EPD has a different unit

Check the unit conversion before using the reduction result.

Common issue: The reduction looks too large

Check that the EPD was applied only to relevant line items.
