Within this Position Paper, the Eurovent Association requests the European Commission (DG Energy and DG Health) to introduce minimum requirements on the fine dust particle concentration in the supply air of ventilation systems in the future review of the EPBD:

• The provision of quality air is crucial in spaces designed for human occupancy, and in many industrial applications with hygienic demands as well.
• The supply air classes in standard EN 16798-3, which are based on WHO air quality guidelines, can serve as a basis for enforceable requirements.
• In the first instance, Eurovent proposes to require that the supply air of ventilation systems be at least SUP2.
• Requirements on particle concentration should be placed in regulations that apply to complete systems or buildings.

In a second step, Eurovent also requests the European Commission to monitor, report, and set EU-wide recommended limits on the particle concentration in indoor air itself.
