Short Answer
vyzn is designed for the Swiss context (KBOB, SIA 380/1, eBKP-H). There is no country switcher (e.g. to Germany). Within the Swiss framework, however, you can choose between a broad selection of certification types and calculation bases.
Why It Matters
Depending on the project and certification goal, different requirements and thresholds apply. Choosing the correct norm configuration directly affects how your building is assessed – in terms of energy, ecology and costs.
How It Works in vyzn
Swiss Context
Calculations in vyzn are designed for the Swiss context:
- LCA according to KBOB (dataset 2022)
- Energy according to SIA 380/1
- Costs according to eBKP-H
A German setup with Ökobaudat or DIN 276 is not currently available. There is no simple "CH/DE switch" that changes all norms, databases and cost standards to another country.
Options Within the Swiss Framework
Energy (SIA 380/1): You can select the certification type – such as SIA 380/1, Minergie, Minergie-P, Minergie-A or Minergie-ECO – as well as the calculation basis (MuKEn 2014 or MuKEn 2017). Depending on your choice, different requirements and thresholds apply, which changes the energy assessment of your building.
LCA: The analysis uses KBOB environmental data. For the assessment, you can apply the appropriate verification framework (e.g. Minergie-ECO or SNBS), which emphasises different indicators and thresholds.
