Opening a window is the biggest waste of energy in every modern home. That was the reason why physicist Noor van Andel and architect Jon Kristinsson invented the Breathing Window, which is now fresh-r®.

To let fresh air in, while keeping the temperature the same, can reduce the need to heat or cool homes to nearly zero. At he same it addresses two key concerns of homeowners:

  1. to take care of the building
  2. to stay healthy

It makes sure the humidity is expelled from the home. So no rot or mould. And the CO2 sensor monitors if the indoor air is fresh and healthy. We want it to be spring in your home, all year round.

The fresh-r® is also wifi-connected. This way you can see what the ventilator and the heat exchanger actually does all the time, real time.
