New to the platform: The Energy Efficiency app is here!

The vyzn app suite keeps growing: The new Energy Efficiency App is now available — fully released, compliant with SIA 380/1, and powered by Enerweb. It enables you to calculate heating demand directly within the 3D model - fast, simple, and transparent.

Real-time analysis for well-founded decisions

The new Energy Efficiency app makes it easy to calculate energy demand directly with your 3D model - precisely and intuitively:

• Real-time calculation – Heating demand based on SIA 380/1 is immediately calculated.
• Automated analysis – The thermally relevant building envelope is automatically detected and managed.
• Clear results – Structured outputs for transparent and well-founded decisions.
• Simple component management – Maintain construction assemblies via a comprehensive and editable catalog.

Two use cases, one goal: better planning

The Energy Efficiency app supports all levels of planning detail – from feasibility studies to official submissions.
It’s built to serve two primary use cases:

1. Optimization: Calculate and compare design variants to improve energy efficiency.
2. Regulatory compliance: Generate certified reports in line with official SIA 380/1 requirements.

Powered by Enerweb – for maximum practicality

Thanks to the integration of Enerweb as the calculation engine, the Energy Efficiency app is built on a robust and field-tested foundation, ensuring both precision and practical application in real-world projects.

“Very cool to see the vyzn app suite growing! We are pleased that Enerweb serves as the basis for the new energy efficiency app and is thus making a further contribution to the practical implementation of SIA 380/1. ”

— Chris Bürgi, Co-founder of Enerhaus Web Services GmbH

With the Energy Efficiency app, vyzn is taking another step towards enabling holistic planning. Heating demand and Life Cycle Assessment can now be analyzed directly in the 3D model - compliant, efficient and comprehensible.
