From digital building models to simulation-ready BEM – automatically

Today, building simulation models are still built manually, from scratch. That takes time and money – so simulations rarely happen when they'd matter most: at the very start of a project, when decisions have the greatest leverage.
In her first video, our CTO Romana explains how vyzn is changing that.
The problem with simulation today
Building energy models (BEM) are traditionally rebuilt by hand for every simulation. The effort is so high that early-stage planning teams skip simulation entirely – or run it late, once the key decisions are already locked in. As a result, the most consequential choices are made with the least insight.
Turning digital models into BEM, automatically
vyzn automatically transforms digital building models into simulation-ready Building Energy Models (BEM) – with no manual rework and no extra effort. The model you already have becomes the model you can simulate.
Fast insight from the very first decision
That means fast insight into energy demand and thermal comfort throughout early planning – not as a separate, one-off study, but as an integral part of the planning process.
And because vyzn evaluates these metrics alongside its analysis of CO₂ emissions and cost, the key performance dimensions are assessed together – not one at a time. The trade-offs between energy, comfort, carbon, and cost become visible at a glance, while there's still room to act on them.
This is the first in a short series. Part two is coming.
