Energy-efficient ventilation

Ventilation is necessary for the supply of fresh air and the removal of polluted air. When there is no need for ventilation (because there is no one in the room or building), the ventilation can of course be turned off or at a lower level. This saves electricity for the fans and energy for cooling or heating.

There are several options for setting the ventilation to be energy efficient:

Link with lighting

A simple form is to link the ventilation to the lighting switch. This can be used in rooms without windows, such as toilets and showers. Optionally, a timer can be built in, so that it stays on a little longer after the space is empty again.

Timer during operating times

Switch on the ventilation about thirty minutes before the first employee arrives and off when the alarm is switched on again. Check annually whether the timer is in accordance with the usage times of the building.

Overtime timer

In situations with occasional deviating operating times, set an overtime timer. If there is a need for ventilation outside the normal operating hours, the ventilation can be switched on for a certain (extra) period by operating the overtime timer.

CO2 control

With this setting, the installation ventilates based on the amount of CO2 in the air. This is especially applicable in schools and offices.

  • Heating and cooling
  • Check the settings of the heating and cooling every year
  • Demand-driven heating, cooling and ventilation
  • Heat recovery system
  • Infra-red heating panels
  • Use residual heat or cold
