The energy label for ventilation systems for living space was introduced in the EU on 1 January 2016 and was declared mandatory in Switzerland on 1 August 2016.
Together with the introduction of this label, requirements on ventilation systems were formulated which apply to ventilation systems for living space as well as for other uses, and these requirements have been adopted by Switzerland.
The energy efficiency of ventilation systems is to a large extent influenced by proper installation, and correct operation and maintenance.
