There is a climate crisis.

And we have a tool to counter it.

To overcome the climate crisis, we need solutions that can be implemented quickly. It takes technologies and successful companies to bring about rapid change.

Here is how it works

viboo in brief

If Europe's buildings consume 30% less heat, the continent's energy demand and CO₂ emissions could fall by around 10%. With viboo, we also make this possible for old buildings.

About us

To overcome the climate crisis, we need solutions that can be implemented quickly. Reducing heat consumption in every European building by 30% would reduce the continent's total energy demand and CO2 emissions by around 10%. It takes technologies and successful companies to bring about rapid change.

viboo is based on years of research at Empa and ETH Zurich as well as at other world-leading laboratories for building automation, such as RWTH Aachen and the Lawrence Berkeley National Lab.
