Ventilation based on utilisation at work

The greatest energy savings in ventilation is often gained with demand-controlled operation.

The energy consumed by ventilation falls down to less than half when the power of ventilation is reduced by the same amount. When the rooms are empty, the need for ventilation decreases significantly and it is sensible to decrease ventilation.

Changing working environment – changing needs

The length of a working day used to be standard. Everybody was at work from eight to four and the need was at its greatest then. Nowadays, however, the rooms are more varied and work is more mobile. Offices may be empty for long periods of time as the employees work remotely, visit their customers or sit at meetings. The quality of air in a meeting room full of people can be lousy, whereas ventilation is at full power in the offices, consuming energy unnecessarily.

Decentralised ventilation and carbon dioxide sensors create automatic room-specific ventilation. The sensors measure the quality of indoor air and boost ventilation when needed. This ensures that air in the meeting room stays fresh and the participants stay awake, while ventilation in the empty rooms decreases, keeping energy consumption in control.
