Smarter decisions,
better buildings.
The decisions that define your building project are made in early planning phases and in competition. vyzn brings clarity before it gets expensive.
- Steer cost, CO₂, energy and comfort at a glance - data-driven, not opinion-driven
- Capture potential, resolve trade-offs, fix risks - while change is still possible
- AI-powered, standards-compliant answers straight from the 3D model - without endless back-and-forth

Use cases
How vyzn helps you reach your goals
Smart decisions. At the right moment.
-
01Competition
Compare entries objectively
How do you compare competition entries when every team makes different assumptions? With vyzn you analyse all entries on the same data basis - precise, with no room for interpretation. A decision you can defend internally and externally.
-
02Early planning
Evaluate variants with confidence
Timber or concrete? Heat pump or geothermal probe? New build or renovation? vyzn gives you the basis to quantify every scenario systematically - and to steer the project deliberately toward the optimal variant.
-
03Before the build decision
Lock in the design stage
What can still be improved - and which weak points have to be eliminated? The more concrete the design stage, the more is at stake. With vyzn you can review every design stage holistically - standards-compliant and report-ready.
-
04Reporting
Data for Scope 3
Where does the CO2 data for your Scope 3 reporting come from, without weeks of manual work? With vyzn you get structured emissions data straight from the digital building model - auditable and report-ready.
-
05Portfolio analysis
Learn from your building stock
What are the biggest drivers across all your properties? The learnings feed into upcoming renovations and new builds: clearer requirements for the planning team, better projects from the start.
The optimization gap
Most decisions get made on opinions.
Done the traditional way, a holistic analysis takes around 60 weeks - so in the early phase it rarely happens. That is exactly where the difference between a good and an expensive real estate and building project is made.
Without vyzn
for a holistic analysis
- ✕ One metric at a time - never weighed together
- ✕ Decisions locked before the data arrives
- ✕ The result: too expensive, too many emissions, wasted resources, too hot in summer
With vyzn
for the same answers - on the real model
- ✓ Cost, emissions, energy & comfort on one basis
- ✓ Every variant compared on the same data
- ✓ A decision you can defend to the board and authorities
The edge
With vyzn, you’re already ahead.
Traditional analyses take weeks. You decide in minutes, backed by data - and get measurably more out of every project.
While others are still calculating, you’ve already decided.
Holistic optimization
One model. Five bundles. The optimal variant.
No single metric leads - vyzn weighs the whole building project at once. Each bundle includes several apps, usable on their own or combined - conformant to Swiss (SIA) and German (DIN) norms.
Reduce CO₂ emissions and reach your sustainability goals.

The technology behind it
One engine: DMP. Unlimited variants.
Deep Model Processing (DMP) turns any 3D building model into a clean, simulation-ready model in minutes - the foundation every bundle runs on. And it gets smarter with every project.
- Any 3D model. Instantly analysable.
- Simulation-ready in minutes
- ETH Zürich technology
- Smarter with every model
In short
Real analysis. Real model. Real numbers.
- ✓ One model, every metric: emissions, energy, cost and comfort straight from your 3D model
- ✓ Norm-ready results for Minergie, SNBS, DGNB, SIA and DIN - reports you can hand over
- ✓ Run it yourself - or let us run it for you as a service package
Testimonials
Leading construction professionals develop with vyzn
With the intelligent use of 3D models, we can precisely evaluate our sustainability goals using the vyzn software - all within a single platform. We are particularly impressed by the efficiency and clarity that vyzn brings to complex projects.
Sandro InfangerHead of Sustainability
Thanks to vyzn, we were able to examine detailed scenarios impacting greenhouse gases and embodied energy during the preliminary project phase, giving us as developers a competitive edge and a solid foundation for decision-making.
Fabian StutzHead of Sustainability & Innovation
Thanks to vyzn, a short sprint is enough to compare component costs, life cycle assessments, and energy consumption across different materialization options. vyzn provides analytically driven decision-making foundations.
Nathaniel LloydAcquisitions Manager / Architect SIA
With its model-based approach, vyzn fits seamlessly into our BIM processes and lets us run project analyses efficiently and precisely.
Ferenc GorHead of Digitalization / BIM
Open collaboration between the building owner, the general planner and vyzn is the key - everyone involved has to actively embrace innovative approaches.
Ralph HagenAbteilungsleiter Hochbauamt St. Gallen
From the competition phase through to realization, vyzn enables us to develop architectural design decisions and sustainability criteria in parallel and to evaluate them transparently. Collaboration with consultants becomes more efficient, since everyone works on the same platform, with the same data.
Leon DirksenLeadership Board
Reliable life cycle assessments across all SIA phases are crucial for us, so we can give our clients the best possible basis for their decisions. vyzn shows the direct link between the digital model and the LCA figures - a real added value.
Mikko LangeSenior Manager, Owner Advisory & Sustainable Building
vyzn enables my team to run digital processes efficiently and to calculate and optimise embodied energy and CO2 from 3D models - for sustainable building design.
