Short summary
IEA EBC Annex 80 Resilient Cooling of Buildings was started against the background of a worldwide rapidly growing need for cooling. It aimed to develop, evaluate, and communicate solutions for resilient cooling and overheating protection of buildings during heat waves and power outages.
Methodology
Methodologically, the research activity is organized into four subtasks and further five over-arching task groups.
Systematic evaluation of existing cooling technologies, their potential, limitations, and qualities of resilience.
Development and improvement of cooling technologies in terms of robustness, efficiency, CO2 neutrality and affordability.
Evaluate the real-world performance of cooling technologies to identify performance gaps and develop solutions to systematically overcome them.
Identification and communication of regulatory measures that can support the broad application of resilient cooling technologies.
The results of Annex 80 are documented in seven deliverables in numerous scientific publications and are freely available.
Objectives
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. The term "resilient cooling of buildings" refers to energy efficient, low emission, and financially affordable cooling concepts that increase resilience and prevent thermal and other climate change impacts at global and local level.
Annex 80 covers the spectrum of the following four technology groups:
Reducing heat gains to the indoor environment and people environments
Removing sensible heat from the indoor environment
Increasing personal comfort apart from space cooling
Removing latent heat from indoor environment

Results
Annex 80 made significant contributions to the professionalization and application support of resilient cooling of buildings and expanded the possibilities for its application in a wide range of climate zones and building types through several scientific publications and handbooks. It assessed the state-of-the-art of numerous cooling solutions and contributed to the definition of “resilient cooling of building”. It developed and documented a method to create future weather files and an impact assessment guideline for building simulation modelling.
