This webinar, will discuss the road towards a robust comprehensive IAQ metric for the assessment of the performance of ventilation.


It sets the starting stage for subtask 1 of the new IEA EBC Annex 86 ‘energy efficient IAQ management in residential buildings.


After a short introduction, the three speakers will first look at the open issues that remain after the work in Annex 68.

After all this, there will be time for discussion and input for future work.


This webinar is organized by the Air Infiltration and Ventilation Centre ( & the IEA EBC Annex 86 “Energy Efficient Indoor Air Quality Management in Residential Buildings” ( The webinar is facilitated by INIVE (
