Natural Ventilation

Once your building's windows are under KNX control it is a simple procedure to enable natural ventilation. Using CO2 sensors and/or air quality sensors, the windows can be automatically opened if the carbon dioxide levels rise above a certain threshold or the air quality drops. This approach is widely used in rooms that regularly have a large number of occupants, e.g. classrooms.

Features

  • Adjustable CO2 / air quality thresholds.
  • Built in dead-band / hysteresis to prevent window ‘flap’.
  • Any off-the-shelf CO2 / air quality sensor can be interfaced to KNX
  • Real time CO2 /air quality measurements can be displayed on head end visualization

Benefits

  • Uses less energy than active fans
  • Delivers optimum environmental quality
  • Utilize existing KNX network
