The 41^st AIVC – ASHRAE IAQ joint Conference, co-organized by ASHRAE & AIVC, was held on 4-6 May 2022 in Athens. The event drew around 185 participants (in person and remotely) – academic researchers, engineering and consulting firms, industry representatives, people involved in standardisation, policy makers, manufacturers & stakeholders and international organizations.

During the event, the 90 minutes topical session “Ventilative Cooling to Reduce Overheating in Buildings to Achieve Good Well-Being: Framing, New Design Approaches and Cases – It Works!” organized by Christoffer Plesner (VELUX, DK) & Jannick Roth (WindowMaster, DK) took place. The session included 7 presentations by international experts and focused on ventilative cooling (VC) and its importance and showed documented case studies. New developments were revealed such as the implementation of VC in international standards, findings of recently finished research projects, etc. Furthermore, the workshop highlighted the aspects to be aware of to get a well-performing VC system and some recommendations going along with this.

The detailed agenda of the topical session follows:

• Introduction (Jannick Roth, WindowMaster International A/S, Vedbæk, Denmark)
• Introduction to Ventilative Cooling and Its Relevance (Per Heiselberg, Aalborg University, Aalborg, Denmark
• Upcoming European and International Technical Documents on “Ventilative Cooling Systems – Design” in CEN/ISO (Christoffer Plesner, VELUX A/S, Hørsholm, Denmark)
• Introduction to the International Venticool Platform and the IEA EBC Annex 62 Deliverables (Hilde Breesch, KU Leuven, Leuven, Belgium)
• Danish Design Guide on “Ventilative Cooling” for Natural Ventilative Cooling: Example from a Danish Residential Building in Ry (Per Heiselberg, Aalborg University, Aalborg, Denmark)
• Standardization of an Evaluation Methodology for Natural Ventilative Cooling Potential in Early Stage Design of Buildings (Annamaria Belleri, Ph.D., Eurac Research, Bolzano, Italy)
• Night Cooling as a Ventilative Cooling Solution for a Belgian Residential Building (Hilde Breesch, KU Leuven, Leuven, Belgium)
• Danish Office Buildings (Jannick Roth, WindowMaster International A/S, Vedbæk, Denmark)
