Eurovent, REHVA, and Nordic Ventilation Group have launched a common proposal on implementing Indoor Environmental Quality (IEQ) requirements introduced by EPBD under revision.

These new provisions added by the Commission's and Parliament's initiative, represent an important step forward to ensure healthy and comfortable IEQ in buildings.

Guidelines and examples

In this document, IEQ substance and requirements are explained just on a few pages

In this document, IEQ substance and requirements are explained just on a few pages. It is shown which items need regulatory effort and which aspects can be left for technical guidance documents such as European standards or national technical guidance.

Guidelines and examples are presented on how essential IEQ requirements can be implemented on a national level.

Article 11a updates

Also, some minor, but important changes are suggested to make Article 11a implementation technically and economically feasible.

The guidance was prepared in a joint effort by Eurovent, REHVA, and Nordic Ventilation Group. From Eurovent, input was provided by its newly set up Issue Group ‘Indoor Environmental Quality’ (IG-IEQ).
