Webinar: Future weather data and heatwaves

31. May 2022
Online, AT

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 on their 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.


This series of webinars is 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.

Content Description

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

About IEA EBC Annex 80 - Resilient Cooling of Buildings

Annex 80 Resilient Cooling of Buildings is an international research project of the IEA Energy in Buildings and Communities (EBC) programme. It is the motivation of Annex 80 to develop, assess and communicate solutions of resilient cooling and overheating protection.

Resilient Cooling is used to denote low energy and low carbon cooling solutions that strengthen the ability of individuals and our community as a whole to withstand, and also prevent, thermal and other impacts of changes in global and local climates. It encompasses the assessment and Research & Development of both active and passive cooling technologies. 

The Annex 80’s main objective is to support a rapid transition to an environment where resilient low energy and low carbon cooling systems are the mainstream and preferred solutions for cooling and overheating issues in buildings.

About venticool

The platform for resilient ventilative cooling, venticool supports better guidance for the appropriate implementation of resilient ventilative cooling strategies as well as adequate credit for such strategies in building regulations.

The platform philosophy is to pull resources together and to avoid duplicating efforts to maximise the impact of existing and new initiatives. venticool has been initiated by the International Network for Information on Ventilation and Energy Performance (INIVE EEIG) with the financial and/or technical support of the following partners: Agoria-NAVENTA, Reyaners Aluminum, Velux and WindowMaster.

About AIVC

Created in 1979, the Air Infiltration and Ventilation Centre is one of the projects/annexes running under the International Energy Agency's Energy in Buildings and Communities (IEA-EBC) Programme.

With the support of its member countries as well as key experts and two associations (REHVA, IBPSA, ISIAQ), the AIVC offers industry and research organisations technical support aimed at better understanding the ventilation challenges and optimising energy efficient ventilation.
