Natural ventilation 

By natural ventilation the indoor climate is regulated by means of a controlled air change through windows that open and close automatically.

The indoor climate is regulated by sensors that measure the air quality in the room. When there is a need for fresh air the windows will open automatically.

Rain and wind sensors fitted outside the building makes sure that the windows will close in case of rain or strong wind.


Natural ventilation is architecturally more beautiful

  • No unsightly pipe or duct penetrations, and space consuming ventilation units.
  • Possibility of increased ceiling height, since natural ventilation does not require suspended ceilings.
  • More daylight and transparency, for example atriums that can be used for natural ventilation.


Reduced energy consumption

Natural ventilation regulates the indoor climate by a controlled air flow through the windows.

Compared to mechanical ventilation natural ventilation uses only a small amount of energy when the windows open and close.

A head to head comparison shows that natural ventilation has a 40% lower CO2 emission than a system with mechanical ventilation.
