This topical session provides insights into the challenges of resilient cooling in a changing climate. Research outcomes from the EBC Annex 80 as well as findings from topical related research work will be presented. Annex 80 sought to provide a sound basis for the assessment of cooling technologies by creating concise sets of future weather data and heat waves. Agnese Salvati together with Maria Kolokotroni are taking this approach further by assessing the impact of urban microclimate on ventilation and thermal performance of multi-family residential buildings. The definition of Key Performance Indicators (KPI) for resilient cooling has been an important task of Annex 80 since its start in 2019. Abantika Sengupta and Adam O’Donovan present two papers where these definitions are applied in the evaluation of case study buildings in Ireland and Belgium.
