What this is

Building is deciding.
And every decision leaves a mark for 50 years.

Descarboniza is the technical decision tool for building with less carbon. A side-by-side comparator of construction systems, a directory of verified manufacturers, and environmental data you can defend in front of a client, a project report or a tender.

The industry has spent years talking about sustainability without the tools to prove it. That's what we're changing.

Vega checks the DB-HE and tells you what to change.

Attach the IFC, answer only what is missing and in under a minute you get the verdict for HE0, HE1, HE4, HE5 and HE6, the plan to comply, the estimated energy label and the report. In the browser, nothing to install, and never replacing the officially approved software.
