Selected recordings from the venticool webinar “Ventilative cooling and summer comfort: Freevent project in France”


Ventilative cooling reduces overheating, improves summer comfort and decreases cooling loads. It is therefore one of the most efficient ways to improve summer comfort. Conditions on site, thermal inertia, solar control and other constraints have an impact on the choice of the system and its design. The overall performance is linked to good sizing, design, correct usage of thermal storage, and last but not least a correct control, commissioning and maintenance.

FREEVENT is a French multi-partner project (ALLIE’AIR, ALDES, EGE, ACA-O and APEBAT) on ventilative cooling,financed by ADEME. The project includes a bibliography study, monitoring activities on various
The principal objective of this webinar was to present this project and to give information and recommendations on designing these systems and assessing their performance.

This webinar was jointly organised by the FREEVENT project and venticool ( in cooperation with the Air Infiltration and Ventilation Centre ( The webinar was hosted by INIVE (
