The current development in building energy efficiency towards nZEB buildings represents a number of new challenges to design and construction. One of these major challenges is the increased need for cooling in these highly insulated and airtight buildings, which is not only present in the summer period but also in the shoulder seasons and in offices even in midwinter. Ventilative cooling can be an energy efficient solution to address this cooling challenge in buildings.

This webinar presented the main outcomes of IEA EBC Annex 62 on ventilative cooling design and gave examples of applications and lessons learned. This webinar was organised by INIVE EEIG ( with the support of the IEA-EBC annex 62 on ventilative cooling ( and the venticool platform (, and in cooperation with the Air Infiltration and Ventilation Centre (
