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 resilient ventilative cooling (venticool) & the Dutch 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 international 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 “Resilient Ventilative Cooling” track at the AIVC 2022 conference consisted of 30 presentations organized in 5 sessions, 3 of which were topical sessions with a number of invited presentations:

1. Ventilative cooling & climate change
2. Resilient cooling in a changing climate
3. Ventilative & resilient cooling
4. New IEA EBC Annex 87 on Personalized Environmental Control Systems (PECS)
5. Ventilative cooling to reduce overheating in buildings in ventilation related standards and legislation in the context of well-being, sustainability and energy

The article available here presents main trends, ideas, considerations and conclusions that emerged from the two days of the conference on this topic. The main topics covered by the speakers varied from resilience (future weather data development, assessment, design), over new technologies & control to legislation & standardization.
