Level(s) is the European Commission’s voluntary framework for reporting the sustainability performance of buildings. It is not a national regulation and not a certification — it is a common reporting structure that translates building performance into a set of core indicators understood across the EU. Real-Time LCA exposes a Level(s) calculation type in every country it supports. It uses the full EN 15978 module set with no threshold attached.

​
Coverage

  • Reference study period: 50 years.
  • Indicator: Global Warming Potential (GWP), kg CO₂-eq per m² GFA per year.
  • Threshold: none — Level(s) is a reporting framework, not a limit-value regulation.

​
When to use Level(s)

  • Reporting in a country without a national regulation in Real-Time LCA — France, Italy, the Netherlands, Spain, and the United Kingdom currently only have Level(s) and Custom as pre-configured calculation types.
  • Cross-border comparison — Level(s) produces results in a common structure that is meaningful across all EU member states.
  • Parallel reporting alongside a national calculation — a project can run a national calculation (BR18, TEK17, Klimatdeklaration, Climate Declaration, HMS, QNG, IGBC WLC, etc.) and a Level(s) calculation side by side without conflict.

​
Relationship to other standards

Level(s) uses EN 15978 as its calculation method and reads product data structured per EN 15804+A2. Selecting Level(s) on a project in Real-Time LCA therefore produces results that are simultaneously consistent with both standards.
