Success Story · Public Sector Client
Only one of three variants meets summer thermal protection. vyzn showed it at the preliminary design stage.
6design stages evaluated
4dimensions in one model
1 of 3variants meets SIA 180
The starting point
The Canton of St. Gallen is converting and extending its State Archives. The target is SNBS Building Gold. At the preliminary design stage it was unclear whether the design would stay within the limits for greenhouse gas emissions and embodied energy, and whether the building would remain comfortable in summer.
The result
- Every design stage assessed instantly: vyzn automatically evaluated 6 digital building models, covering emissions, energy, comfort and component areas according to eBKP-H as the basis for costs.
- The right variant found: only the variant with improved insulation and solar control glass in the roof window meets summer thermal protection and performs best overall.
- Ready to use for SNBS certification: the results feed directly into the verification.
- Risks spotted early: the adjustments were made at the preliminary design stage, before changes become expensive.
Beyond the project
- 1CompetitionCompare entries objectively
Competition entries can be checked against the same key figures before the jury decides.
- 2Before the construction decisionSecure the chosen variant
Every new design stage is automatically checked against the target values until the decision is made.
- 3PortfolioAll projects, one language
The canton's building projects become comparable using consistent key figures.
«Open collaboration between the client, the general planner and vyzn was the key - everyone involved actively supported innovative approaches.»
