How to compare two versions

Purpose

See how the climate impact changes between two or more versions of the same project, e.g. before and after a change.

Prerequisites

The project has at least two versions, and they’ve been calculated.

Steps

1. Go to General information.
2. Check the versions you want to compare in the version list.
3. Watch the Version comparison chart at the top of the page update automatically.
4. Choose a unit (per m²/year, per m², or total) in the chart card’s unit selector, or choose Weight (kg) to compare the versions’ weight instead of climate impact (limit-value lines and the pass/exceeds status only show in the m²/year view).

Result

The chart shows the climate impact for each checked version side by side, so you can see whether a change improved or worsened the result.
