Well-insulated and air-tight buildings are known to be vulnerable to overheating. An increase in the severity and duration of heatwaves is expected, resulting in more severe overheating risks, affecting in turn the health and mortality of building users. To achieve more future-proof buildings, it is crucial to design buildings that are “resilient” to overheating in future climate conditions.

It is the motivation of IEA EBC Annex 80 “Resilient Cooling of Buildings” to develop, assess and communicate active and passive solutions of resilient cooling and overheating protection. Resilience was defined and indicators were developed to assess the resilience of cooling technologies in subtask A “Fundamentals”. Moreover, shocks like heatwaves, were defined for all climate zones around the world. Subtask B “Solutions” systematically assessed the benefits, limitations, and performance indicators of resilient cooling solutions. In addition, specific R&D towards new developments and improvements of resilient cooling and overheating protection solutions was carried out. Subtask C “Field Studies” showed the opportunities and benefits of resilient cooling through the analysis and evaluation of well-documented applications. Finally, subtask D “Policy Actions” dealt with policy related endeavors, promoting energy efficiency and resilience in cooling.

This series of 4 webinars presented the results of IEA EBC Annex 80 on:

• Indicators to assess resilience of cooling in buildings [May 10^th, 2022 - 15:00-16:15 CET- Completed]
• Future weather data and heatwaves [May 31^st, 2022 - 16:00-17:15 CET - Completed]
• Examples of resilient cooling solutions [September 13^th, 2022 - 15:00-16:15 CET - Completed]
• Case studies and policy recommendations [September 20^th, 2022 - 15:00-16:15 CET - Completed]

This series of  webinars was organized by INIVE EEIG with the support of the IEA EBC Annex 80 Resilient Cooling of Buildings and the venticool platform , and in cooperation with the Air Infiltration and Ventilation Centre.
