The AIVC – TightVent – venticool 2022 joint Conference “Ventilation Challenges in a Changing World”, organized by the International Network on Ventilation and Energy Performance (INIVE) on behalf of the Air Infiltration and Ventilation Centre (AIVC), the Building and Ductwork Airtightness Platform (TightVent Europe), the international platform for ventilative cooling (venticool) & the Netherlands Organization for Applied Scientific Research (TNO), was held on 5-6 October in Rotterdam, Netherlands. The event drew just over 140 participants – researchers, engineers & architects, policy makers or regulatory bodies, manufacturers & stakeholders and international organizations from 22 countries.

The programme included 3 parallel tracks of structured sessions with around 130 presentations covering the main conference topics namely: Smart Ventilation, Indoor Air Quality (IAQ) and Health; Building & Ductwork Airtightness; Ventilative cooling – Resilient cooling. A special session i.e. “90 seconds industry presentations” was also organized and devoted to the sponsors of the event.

The event has also been a major discussion place for on-going projects such as, the IEA EBC annex 87 “Energy and Indoor Environmental Quality Performance of Personalized Environmental Control Systems”, and the IEA EBC Annex 80 “Resilient Cooling of Buildings”.

The airtightness track at the AIVC 2022 conference consisted of 24 presentations organized in 4 sessions of which 2 were topical sessions with a number of invited presentations. Three main topics were discussed: what are the national regulations regarding building and ductwork airtightness? How to check the implementation? And what about the building airtightness durability over time?

The article available here presents main trends, ideas, considerations and conclusions that emerged from the two days of the conference on this topic.
