Our Story

At C3RRO (pronounced "zero"), our story began with our extensive experience in developing some of the world-renowned WUFI products, including WUFI Plus, the hygrothermal building simulation tool, and WUFI Passive, the building energy certification software. Our work at the Fraunhofer Institute for Building Physics made us realize the importance of bringing these tools out of the research environment and into practical, modern solutions to get the next generation of these powerful building science tools into the hands of those who can best use them to create sustainable, healthy, and efficient buildings.

The name C3RRO represents our core services – Coding, Computing, and Consulting. With these services, we aim to help build a zero-carbon future, where buildings consume zero energy, with zero durability, comfort, or air quality issues.

As a Bavarian company, we draw inspiration from the white and blue Cirrocumulus sky and bring "moisture (simulation) into the cloud" through cloud-powered hygrothermal simulation. Our goal is to unleash the full potential of hygrothermal building simulation and contribute to a better, more sustainable built environment.
