Use cases
Where vyzn makes the difference.
Smart decisions. At the right moment.
-
01Competition
Compare entries objectively
Compare all teams in the study commission on the same data basis - objective and defensible, internally and externally.
-
02Early planning
Evaluate variants with confidence
Timber or concrete? Heat pump or geothermal? Every scenario quantified - and the project steered to the best variant.
-
03Before the build decision
Lock in the design stage
Does the design meet every project target? Review the whole design stage holistically and surface weak points before key decisions are made.
-
04Reporting
Data for Scope 3
Structured CO₂ data for Scope 3 reporting - auditable and report-ready.
-
05Portfolio analysis
Learn from your building stock
Spot the biggest drivers across your portfolio - for clearer requirements and better projects from the start.
The optimization gap
The costliest decisions are still made flying blind.
In early project phases the data is thinnest, because a holistic analysis traditionally takes around 60 weeks. vyzn gives you the knowledge edge, exactly when it matters most.
Without vyzn
for a holistic analysis: manual, fragmented, expensive
- ✕ Each discipline analysed on its own, never weighed together
- ✕ Decisions made before the data arrives
- ✕ The result: too expensive, too CO₂-intensive, high energy demand
With vyzn
for sharper results, simulated on the 3D model
- ✓ Cost, energy, CO₂ and comfort weighed together
- ✓ The data is there before you decide
- ✓ The result: the optimal building design, aligned with your project goals
The edge
With vyzn, you’re already ahead.
With AI-powered analyses you decide backed by data and get measurably more out of every project.
While others are still calculating, you’ve already decided.
Holistic optimization
Spot hidden risks and untapped potential - straight from the 3D model.
Cut costs with no compromise on CO₂ emissions, energy, comfort or safety: with vyzn you bring every project goal into balance.
Reduce CO₂ emissions and reach your sustainability goals.

The technology behind it
One engine: DMP.
AI agents: vyzn Advisor.
Deep Model Processing (DMP) makes any 3D model and any 2D plan simulation-ready in minutes. On top, AI agents act as your personal advisor: they analyse your project, answer all your questions and surface opportunities to improve.
- 2D plans, DWG or 3D model. Instantly simulatable.
- AI agents across every target dimension. The optimal variant for your projects.
In short
Better buildings, higher margin, less CO₂ - decided before it gets expensive.
- ✓ Cost, CO₂, energy and comfort - weighed together
- ✓ Precise, AI-powered and standards-compliant results, already in early project phases
- ✓ Use the vyzn platform yourself - or have a vyzn expert deliver the results
Testimonials
Leading owners & developers work 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 actively embraced the 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.
