Mechanical ventilation

Mechanical ventilation refreshes the air in the house continuously, if properly applied and regularly maintained. Don't confuse this with a ceiling ventilator or an extractor hood; a mechanical ventilation withdraws air from the entire house, but does not put fresh air back in. The tenant should take care of this himself by means of natural ventilation


Modern mechanical ventilation is regulated with a sensor. Most common are sensor that measure the concentration of CO2 or the humitidy, compare this with a benchmark value and subsequently switch on or switch off the ventilation system.

Maintenance

Cleaning and maintaining the filters in a mechanical ventilation system is the responsibility of the tenant. The grid is best cleaned with a brush or with a vacuum cleaner. Sometimes it's possible to take out the grid and wash this with a mix of water and detergent. 

Ventilation tips

  • Ensure that air can always flow inside via grids. If the house is shut tight, air is withdrawn from the crawl space which often contains damp and mould
  • Never shut off mechanical ventilation, unless in case of an environmental disaster when it's asked to close doors and windows.
  • Set the ventilation on the highest setting during showering, cooking, if you're drying the laundry inside or if there are many people inside the house. 
  • After showering or cooking, leave the ventilation on the highest setting for approximately another 20 minutes. 
  • Set the ventilation on the lowest setting when you are not at home.
