Eurovent has published a new recommendation on ventilation systems in new and renovated residential buildings. It provides guidance on the application of technologies that ensure good indoor air quality (IAQ).
The recommendation responds directly to the objectives of the recast Energy Performance of Buildings Directive (EPBD 2024/1275), advocating for harmonised IAQ and ventilation requirements across all EU member sates. It highlights the role of mechanical ventilation not only in new construction but also in major renovations, stressing that improved airtightness without proper ventilation can severely compromise occupant health and well-being.
The Vice-Chairperson of Eurovent Product Group Residential Ventilation Systems (PG-RVS), Arie Veldhuijzen, said: “It is important that the recast EPBD contains provisions for IAQ and ventilation and links this to health. In so doing, it is essential to clarify how this can be applied in practice. With this recommendation, we demonstrate how ventilation systems work and which ventilation solution is suitable for which situation. This is important for many people, not only for those involved in the implementation of the recast EPBD, but for anyone involved in new construction or renovation.”
The document is available as a free download from the Eurovent website.
