Overview

The starting page for LCA calculations: the building’s total result on one screen. See the full walkthrough in Read the result.

Four key figures at the top:

Element	Meaning
Climate impact vs. BR requirements (§298)	The building’s total result in kg CO₂-eq/m²/year, held up against the limit value: Passes or Exceeds. If the limit value cannot be determined, neither is shown, but the reason is
Benchmark	A short comparison against the dataset of reference buildings
Top contributor	The single building element that contributes the most, with value and share
Data basis (EPD data types)	How much of the result is based on specific EPDs rather than generic values

Below them sits one card per standalone view: GWP by module, Hotspot by building element, Sunburst chart, Sankey diagram, Materials, Accumulated GWP over time, Benchmark, Limit values, CO₂ development by version and Result table. Each card is a condensed version, click through for details.

Recalculate at the top right runs the calculation again: it never happens automatically. Next to it sits Export, the same Excel/BR export menu as in the result table, see How to export results to Excel.
